大学生毕业后面临的挑战作文英语全文共3篇示例，供读者参考篇1The Road Ahead: Challenges Facing College GraduatesAs I approach the end of my college journey, I can't help but feel a mix of excitement and trepidation. The world beyond the familiar walls of academia promises new adventures and opportunities, but it also presents a daunting set of challenges that every fresh graduate must confront. In this essay, I will explore some of the key obstacles that lie ahead for those of us embarking on this new chapter of our lives.One of the most significant challenges facing college graduates is the highly competitive job market. With anever-increasing number of degree holders vying for limited positions, standing out from the crowd has become more crucial than ever. Employers are not only looking for academic qualifications but also seeking candidates with relevant experience, specialized skills, and a well-rounded personality. Building a strong resume and developing a professional networkduring college can give graduates a head start, but even then, the job search process can be grueling and filled with rejections.Furthermore, the mismatch between the skills acquired in college and the demands of the modern workplace can pose a significant hurdle. While our academic pursuits have equipped us with a solid theoretical foundation, many employers prioritize practical, industry-specific knowledge and the ability to hit the ground running. This gap can make the transition from student to professional particularly challenging, especially in rapidly evolving fields where the curriculum struggles to keep pace with real-world developments.Another formidable challenge that awaits college graduates is financial independence. For many of us, the safety net of parental support or student loans will soon disappear, and we will be solely responsible for managing our finances. Navigating the complexities of budgeting, saving, investing, and repaying student loans can be overwhelming, especially when coupled with the pressure of finding a well-paying job. Poor financial management during these crucial early years can havelong-lasting consequences, making it essential for graduates to develop sound money management skills.Beyond the professional and financial realms, college graduates also face personal and social challenges. Leaving the structured environment of college and the close-knit community of friends and classmates can be a significant adjustment. Building a new social circle, finding a work-life balance, and maintaining personal relationships can be difficult amidst the demands of a new career. Additionally, the pressure to achieve milestones such as finding a life partner, starting a family, or purchasing a home can weigh heavily on some graduates, adding to the already substantial stress.Mental and emotional well-being is another area of concern for many college graduates. The transition from the relatively sheltered life of a student to the fast-paced and often cutthroat professional world can be a jarring experience. Dealing with rejection, imposter syndrome, and the constant pressure to succeed can take a toll on one's mental health. Developing healthy coping mechanisms, seeking support when needed, and prioritizing self-care are essential for maintaining a balanced and fulfilling life.In addition to these personal challenges, college graduates may also face societal and global issues that can impact their future prospects. Economic downturns, political instability, andenvironmental concerns can all shape the job market and the overall landscape in which we will be launching our careers. Adaptability, resilience, and a willingness to embrace change will be key to navigating these broader challenges.Despite the formidable obstacles that lie ahead, I remain optimistic about the future. College has equipped me with a wealth of knowledge, critical thinking skills, and a passion for learning that will serve as valuable assets in overcoming these challenges. Furthermore, the experiences and lessons learned throughout my academic journey have instilled in me a sense of perseverance and determination that will undoubtedly prove invaluable in the years to come.As I embark on this new chapter, I am reminded of the wise words of Nelson Mandela: "After climbing a great hill, one only finds that there are many more hills to climb." The challenges facing college graduates are numerous and daunting, but they are not insurmountable. With hard work, dedication, and a willingness to adapt and learn, we can conquer these obstacles and pave the way for a successful and fulfilling future.In conclusion, the road ahead for college graduates is filled with challenges, but it is also brimming with opportunities for personal and professional growth. By embracing thesechallenges head-on, cultivating resilience, and continuing to learn and evolve, we can turn adversity into triumph and shape our own destinies. The journey may be arduous, but the rewards of perseverance and hard work will make it all worthwhile.篇2Challenges Facing University GraduatesAs I approach the end of my university journey, I can't help but feel a mix of excitement and trepidation about the road ahead. The student life I've known for the past few years is coming to a close, and I'm being thrust into the great unknown of the "real world." While I'm eager to put my education to use and start my career, I'm also acutely aware of the many challenges that await fresh graduates like myself.One of the biggest hurdles we face is the intense competition in the job market. With each passing year, more and more students are earning degrees, flooding the workforce with qualified candidates vying for a limited number of entry-level positions. Employers can afford to be extremely selective, often requiring not just a degree but also relevant work experience, a polished resume, and a dazzling array of soft skills.For many of us, the concept of finding a job related to our field of study is already a struggle. We've spent years honing our knowledge and skills in a specific discipline, only to discover that the jobs we thought we were preparing for are either scarce or highly competitive. This mismatch between our educational training and the actual job market can be disheartening, forcing us to either settle for positions outside our areas of expertise or continue our studies to make ourselves more marketable.Even for those who manage to secure a job in their desired field, the transition from student to professional can be jarring. The structured, predictable rhythms of university life are replaced by the fast-paced, ever-changing demands of the workplace. We must quickly adapt to new environments, office politics, and the expectations of our employers and colleagues. The ability to multitask, prioritize, and work well under pressure becomes paramount, skills that may not have been emphasized enough in our academic careers.Financial pressures also loom large for many graduates. After years of accumulating student debt, we're expected to not only find employment but also earn enough to start repaying our loans and supporting ourselves independently. The cost of living in many major cities can be prohibitively high, forcing us to makedifficult choices between pursuing our dream jobs and settling for more affordable but less fulfilling positions.Beyond the practical challenges of finding employment and achieving financial stability, there are also personal and emotional hurdles to overcome. Leaving the familiar comfort of university can be isolating, as we're separated from the social networks and support systems we've relied on for years. Building new connections and communities in the working world can be daunting, especially for those who have relocated to new cities or countries for their careers.Moreover, the pressure to "have it all figured out" can be overwhelming. Society often expects us to seamlessly transition from students to full-fledged adults with clear career paths and long-term plans. The reality, however, is that many of us are still grappling with questions of identity, purpose, and what we truly want from our lives and careers. This internal conflict between societal expectations and personal exploration can breed anxiety, self-doubt, and a fear of making the "wrong" choices.Despite these formidable challenges, I remain hopeful and determined. My university experience has equipped me with not just knowledge but also valuable skills in critical thinking, problem-solving, and adaptability. While the road ahead may beuncertain, I'm confident in my ability to navigate its twists and turns, learning and growing along the way.Overcoming these challenges will require resilience, patience, and a willingness to embrace discomfort and uncertainty. It will mean being proactive in seeking out opportunities, networking, and continuously developing new skills. It will involve taking calculated risks, stepping outside my comfort zone, and not being afraid to fail and learn from those failures.Most importantly, it will mean staying true to myself and my values, not losing sight of what truly matters to me amidst the pressures and noise of the working world. Whether it's pursuing a passion, making a positive impact, or simply finding a career that brings me fulfillment and balance, I must remain grounded in my aspirations and let them guide me through the challenges ahead.The path from university to the "real world" is rarely a straight line, and the challenges we face as graduates are numerous and varied. But with determination, resilience, and a willingness to adapt and learn, we can not only overcome these obstacles but also emerge stronger, wiser, and better prepared to tackle whatever life throws our way.For now, I'll savor these final moments of my student life, grateful for the experiences and knowledge I've gained, while simultaneously steeling myself for the adventures and challenges that lie ahead. The road may be long and winding, but I'm ready to embark on the journey, embracing all that it has to offer with open arms and an open mind.篇3The Daunting Challenges Awaiting College GraduatesAs I approach the culmination of my college journey, a myriad of emotions engulfs me. Excitement, trepidation, and a profound sense of uncertainty intermingle, forming a complex tapestry of feelings. The prospect of venturing into the uncharted territory of post-graduate life is both exhilarating and daunting, for the challenges that await are numerous and formidable.The first and most pressing challenge that looms large is the monumental task of securing gainful employment. The job market, ever-competitive and unforgiving, presents a formidable obstacle. With a vast pool of talented individuals vying for limited opportunities, the process of standing out and distinguishing oneself becomes an arduous endeavor. Crafting acompelling resume, honing interview skills, and effectively showcasing one's abilities are critical components of this intricate dance.Moreover, the transition from the structured confines of academia to the dynamic and often unpredictable professional realm can be jarring. The comfort and familiarity of the college environment, with its well-defined schedules and expectations, are replaced by the ever-shifting landscapes of the corporate world. Adapting to new organizational cultures, navigating office politics, and effectively managing time and priorities become paramount skills to cultivate.Financial independence is another formidable challenge that awaits. Gone are the days of relying on parental support or student loans; now, the responsibility of managing one's finances falls squarely on our shoulders. Budgeting, saving, and making prudent financial decisions are essential to achieving long-term stability and success. The temptation to indulge in impulsive spending must be tempered by the wisdom of responsible money management.Relationships, both personal and professional, also undergo significant transformations during this pivotal phase. Maintaining close friendships forged during college years canbecome increasingly challenging as individuals disperse to pursue diverse paths. Simultaneously, the need to forge new connections and build a professional network becomes ever more crucial. Striking the delicate balance between nurturing existing bonds and cultivating new ones is a skill that must be honed.Furthermore, the pursuit of continuous learning and professional development is an imperative in today's rapidly evolving job market. The knowledge and skills acquired during college, while invaluable, may quickly become outmoded in the face of technological advancements and shifting industry demands. Embracing a growth mindset and committing to lifelong learning are essential to remain competitive and relevant in one's chosen field.Perhaps one of the most profound challenges lies in the realm of self-discovery and personal growth. The college years serve as a crucible for self-exploration and identity formation, but the journey does not end there. Post-graduate life presents a myriad of opportunities and choices that can shape our paths in profound ways. Navigating these choices, aligning our actions with our values, and remaining true to our authentic selvesamidst the pressures and expectations of the world is a constant endeavor.Amidst these multifaceted challenges, the importance of resilience and adaptability cannot be overstated. The ability to bounce back from setbacks, learn from failures, and pivot when necessary is a invaluable asset in the ever-changing landscape of the post-college world. Cultivating a growth mindset and embracing a willingness to step out of one's comfort zone are key to thriving in the face of adversity.Yet, despite the formidable nature of these challenges, they also present opportunities for personal growth, self-discovery, and the cultivation of invaluable life skills. Each obstacle overcome is a testament to our strength, determination, and capacity to adapt. The challenges we face today will shape the individuals we become tomorrow, forging us into resilient, resourceful, and well-rounded individuals capable of navigating the complexities of the world.As I stand at the precipice of this new chapter, I am acutely aware of the trials that lie ahead. Yet, I am also emboldened by the knowledge that countless individuals before me have traversed this path, emerging triumphant and transformed by their experiences. With determination, perseverance, and anunwavering commitment to personal growth, I am confident that I, too, can conquer the challenges that await, emerging as a more capable, resilient, and well-rounded individual.The journey ahead may be fraught with obstacles, but it is also rife with possibilities and opportunities for self-discovery. By embracing a growth mindset, cultivating resilience, and remaining true to our values, we can navigate the tumultuous waters of post-graduate life and emerge as the architects of our own destinies.。

过程比结果重要英语作文
过程比结果重要英语作文英文回答：The journey is more important than the destination. This is a common saying that suggests that the experiences and lessons learned along the way are more valuable than achieving a specific goal. While there are certainly times when the destination is the most important thing, such as when you are trying to reach a place of safety or when you have a deadline to meet, there are also many times when the journey is more important.One reason why the journey is more important than the destination is because it is during the journey that you learn and grow. When you are focused on reaching a goal, you may not be paying attention to the things around you. You may not be taking the time to appreciate the scenery or to learn from the people you meet along the way. However, when you take the time to enjoy the journey, you are more likely to learn new things, to grow as a person, and tocreate lasting memories.Another reason why the journey is more important than the destination is because it is during the journey that you build relationships. When you are working towards a goal, you may be so focused on the goal that you neglect the people around you. However, when you take the time to enjoy the journey, you are more likely to build strong relationships with the people you meet along the way. These relationships can last a lifetime and can be a source of support and encouragement in the years to come.Of course, there are times when the destination is important. However, even when the destination is important, it is important to remember that the journey is just as important. The journey is where you learn, grow, and build relationships. The journey is where you create memoriesthat will last a lifetime.中文回答：过程重于结果。

The commercialization of femtocells was investigated in 2008 (through tenders, technical trials, and business models) by MOs worldwide. Femtocells or femto access points (FAPs) are miniature base stations connected to an MO’s network via a broadband connection (e.g., asymmetric digital subscriber line [ADSL]), typically designed for use in residential or small office/home office (SOHO) environments [1–3].For MOs, femtocells may constitute a solu-tion to:•Increase mobile usage indoors — and thus revenues — by combining coverage/capacity enhancements with inexpensive voice ser-vices•Offer innovative data services (music/photo/video download/synchronization, mobile TV, etc.), thus making the mobile phone competitive with a fixed phone, PC, and/or TV•Offer fixed-mobile convergence (FMC) inresponse to WiFi/voice over IP (VoIP),Homezone, and UMA offerings.In addition, femtocells may contribute to:•Churn reduction (e.g., by “capturing” all the members of a family)•Operational expenditure (OPEX) savings on the (macro) backhaul network (due to traffic offload)•Capital expenditure (CAPEX) savings since no new base stations or capacity expansions are needed.End-user benefits from the introduction of fem-tocells, apart from better coverage and inexpen-sive voice tariffs within the “femto zone,” may include “one-phone-one-number-one-bill” and the same services indoors and outdoors.An MO, prior to commercial introduction of femtocells, has to address a considerable list of issues such as possible interference with the macro network [4], impact on the core network,security concerns, interoperability, regulatory/electromagnetic compatibility (EMC) concerns,use of service level agreements (SLAs) for quali-ty of service (QoS) guarantees (especially for voice) over the broadband connection, and avail-ability of platforms/features and packages to be offered.The aim of this article is to investigate whether femtocells may add value to the user and operator. The analysis is based on certain decision making factors (both technical and commercial) that will be assessed according to the experience gained through a request for pro-posals (RFP), a technical trial, and a custom-made investment-revenues analysis tool.The structure of the article is organized as follows. We present generic factors affecting theintroduction of new services/technologies. We investigate the potential exploitation of femto-cells based on the findings derived from certain projects run within COSMOTE in 2008. Finally,we draw some concluding remarks.F ACTORS A FFECTING N EW S ERVICES ’/A PPLICATIONS ’I NTRODUCTIONThe level of adoption and success of a new mobile technology and/or service or application depends on the value offered to both the user and the MO. On the user’s side, value is offered by innovative services and applicationsIEEE Communications Magazine • September 2009A BSTRACTThere is a continuous pursuit by mobile oper-ators (MOs) to improve indoor coverage in order not only to improve voice quality but also to enable higher data rates in home/office envi-ronments. Indoor coverage improvement, in con-junction with inexpensive (voice) offerings, will enable MOs to compete with and take away voice-call-related revenues from fixed network PTTs and/or VoIP operators. Femtocells consti-tute a promising solution to address all of the above. In this article we present our experience from our extensive study and trials of early (pre-standard) femtocell solutions that were available in the 2007–2008 timeframe.George Korinthios, Elina Theodoropoulou, Niki Marouda, Ioanna Mesogiti, Eftychia Nikolitsa, and George Lyberopoulos, COSMOTE — Mobile Communications S.A.Early Experiences and Lessons Learned from Femtocellsscrambling code), interference with the macronetwork [4] and other closely located FAPscould be mitigated. Otherwise:•For a 2G-femto network, a different set ofBCCH frequencies shall be allocated forthe femto network than that utilized in themacro network to avoid co-channel inter-ference between femto-macro layers. Trialresults indicated that co-channel interfer-ence between neighboring FAPs can beparticularly intense (no call establishment)in distances less than 4 m in an open spaceenvironment, whereas no adjacent channelinterference was observed (either FAP-FAPor FAP-macro).•For a 3G-femto network, if utilization of aseparate carrier is not possible, the scram-bling codes allocated to FAPs shall be dis-tinct from those allocated to the macronetwork.In terms of mobility and service continuitysupport, there are the following alternatives forthe operator:•Adjustment of macro and femto networkcell reselection parameters so that userequipment is automatically camped onFAPs once detected1•Exploitation of hierarchical cell structure(HCS) to achieve prioritization of the fem-tocell layer over the macro one•Definition of a separate PLMN-ID (forexclusive use by the femto network)•Introduction of equivalent PLMN feature,which, unlike the case of a separate PLMN-ID, does not require any UE SIM modifica-tionIn the 2G-femto trial, COSMOTE adoptedthe vendor’s recommendation on the use of asecond PLMN-ID. This approach providedinherent support of rove-in and rove-out of thefemto network, by means of searching for thepreferred HPLMN (femto network) or anallowed VPLMN (COSMOTE), respectively.The trial results indicated that the time requiredfor the rove-in procedure (macro->FAP) mayvary from a couple of seconds up to six minutes(i.e., the minimum timer value that can be set atSIM for periodic search of the HPLMN), whilethe rove-out procedure (FAP->macro) requiresa few seconds up to a couple of minutes to becompleted, during which the femto subscriberremains “out of coverage,” experiencing serviceunavailability.On the operator’s side, the implementation ofa dedicated second PLMN-ID for femtocellsnecessitates considerable effort, including:•Request for a new PLMN code (femtoPLMN-ID) from the local regulatoryauthority•Massive replacement of SIM cards for all(existing) subscribers who become femtousers2•Establishment of new international roamingagreements (for the new IMSI series)3•Activation of additional features on corenetwork elementsIn addition, it shall also be investigatedwhether the core network nodes to be connectedto the FGW need to be upgraded (softwareand/or hardware) so as to support the FGWinterfaces. A 3G-FGW, for example, may sup-port standard Iu-CS/Iu-PS interfaces over IPtoward the core network, while a 2G-FGW maysupport a Gb over IP interface to the SGSN. Inaddition to network element upgrades, band-width upgrades on specific interfaces (backhaul,backbone, “routes” to the Internet) might berequired. The expected traffic on these inter-faces can be assessed by means of a dimension-ing study.Integration— In the context of COSMOTE’s2G-femto trial, the integration tasks included IPinterconnection tasks like FQDN to IP mappingwithin DNS4and configuration of a DHCP serv-er to provide IP addresses to FAPs, connectivitytasks like time-division multiplexing (TDM) andGb over IP links between FGW-MSC/SGSN (for2G-femto), SS7 links between AAA-HLR host-ing femto subscribers and/or FAPs (SIM-basedauthentication), in order for users to have accessto all services provided to ordinary subscribers(SMS, MMS, WAP, Internet, voice mail, infor-mation services, etc).The adoption of the second PLMN imple-mentation necessitated:•The activation of the “multiple PLMNs”feature at all MSCs/SGSNs•New femtocell PLMN definition, along withPLMN-specific parameters, at allMSCs/SGSNs and HLR(s)•The activation of the “National Roaming”feature at all MSC/SGSN nodes, along withthe appropriate configuration, in order torestrict the usage of the femto HPLMNonly to femto subscribers and force femtosubscribers to use COSMOTE’s macro net-work while roaming out of FAP coverage•New IMSI analysis (for the IMSI/GPRSattachment of femto subscribers) at allMSCs/SGSNs•Definition of the femto location/routingareas at all MSCs/SGSNs•Number Portability Registrar update withentries for the new femto IMSI series andfemto MSISDN ranges pointing to therespective HLR(s)The HLR/AuC(s) were configured with theIMSI and authentication data for the FAPembedded SIM cards and the femto subscriberSIM cards. In addition, the Alias-IMSI featurewas activated at the HLR to support mapping oftwo IMSIs to a single MSISDN.Provisioning of a Femto User and/or FAPSIM Card— Femtocells necessitate mutualauthentication/certification between the FAPand FGW. Depending on the FAP vendor, thisis done using either standard SIM/USIM authen-tication or a hard protected built-in module(e.g., authentication chip). In case of SIM/USIMauthentication, FAP SIMs shall include —among other data — the following information:IMSI, Ki, certification authority (CA) root cer-tificate, and the FQDN of the FGW. SIM-specif-ic information shall also be configured in theHLR.5To bypass the international roaming agree-ments requirement (due to the second PLMNimplementation) COSMOTE investigated andIEEE Communications Magazine • September 2009implemented “dual-IMSI subscribers SIMs”;provided by an undisclosed SIM vendor. The dual-IMSI SIMs, by utilizing a purpose-built applet at power-on, enabled the use of femto-IMSI whenever a subscriber roams within the allowed PLMNs in “home country” (femto HPLMN or roaming in COSMOTE’s network),whereas the “COSMOTE” PLMN IMSI is used only when the subscriber is roaming abroad, thus eliminating the need for new roaming agree-ments for the new IMSI series.The dual-IMSI SIM shall be provisioned with a single authentication key (Ki) for both IMSIs along with SIM-specific algorithms to enforce the desired functionality. For the realization of the dual-IMSI SIM concept, the HLR shall sup-port mapping of two IMSIs to a single MSISDN,made possible through the alias-IMSI feature.Proper operation of the dual-IMSI SIM card (location update within FAP, macro, and foreign network) was verified through numerous tests.Integration Charging/Provisioning/OSS Sys-tems — The majority of 2G/3G-femto solutions rely on the core network elements to generate call detail records (CDRs), which are subse-quently sent to the existing billing system. Theimplementation of a special charging plan forfemto services may force operators to perform a number of tariff-related modifications within their existing billing system. Modifications should allow for tariff differentiation of transactions performed by femto subscribers between the femto and macro networks or between FAPs.The femto solution itself, however, should sup-port the generation of location-specific informa-tion (unique identifiers) within CDRs according to which tariffs shall be applied. In the 2G-femto trial, tariff differentiation between the femto and the macro was enforced by means of a unique location area assignment to FAPs.A femto solution may incorporate its own provisioning system or be integrated into an existing one. A separate provisioning system will need to be integrated into third party (existing)business support systems like customer relation-ship management (CRM, northbound) and to third party network elements (HLR or AAA,southbound). Prior to any integration, an opera-tor should verify interface compatibility and pro-ceed with the necessary adaptations (if required).The integration of an interactive voice recogni-tion (IVR) system or SMS to the femto provi-sioning system would require additional (integration) effort.Integrating a femto solution in an existing provisioning system is considered less complicat-ed. The procedures used for the provisioning of services to ordinary subscribers shall apply to femto subscribers as well. As a result, only a few amendments to existing procedures may be anticipated.Finally, FGW support (fault management,network statistics, traffic monitoring) in the existing operating system support (OSS) shall be investigated.P ROFITABILITY /P AYBACKFemto-related investment (CAPEX/OPEX)depends on the cost of the femto platform,FAPs, existing network upgrades, O&M/support services, rental and installation (for “public” use of FAPs), labor, advertising/marketing, user acquisition/retention, interconnection/termina-tion fees, FAPs distribution, and so on, while revenues greatly depend on the number of femto subscribers (or FAPs), average revenue per user (ARPU) (based on monthly fee, extra call min-utes), and so on.As far as femtocell deployment is concerned,an MO should take into account certain tariffing restrictions arising from similar packages (e.g.,home zone) of either the same operator or the competition and exploit possible opportunities,for example:•Offer FAPs as a fixed-telephony-like alter-native, to address the greatest possible mar-ket share —individuals or families/SOHO,small to medium enterprises (SMEs), users in public areas (malls, restaurants, cafes,etc.)•Offer simple packages that may allow all members/employees to share a certain amount of free voice call minutes per month or customized packages offering dif-ferentiated sub-packages for each family member/employee•Provide competitive services bundles (voice/non-voice applications: SMS, WAP/MMS, Mobile TV, VoD, etc.) with attrac-tive/affordable pricingResults from our own Investment-Revenues Analysis Tool, incorporating all the above men-tioned parameters, indicate that the FAP price strongly affects the subsidization costs, thus becoming a crucial parameter for the profitabili-ty of extensive deployments [7]. It is envisaged that initially, femtocells will be utilized for oper-ator coordinated coverage extension purposes (e.g., public hotspots, malls) rather than mass market offerings.T IMEFRAME FOR I MPLEMENTATIONFrom the technical viewpoint, a typical imple-mentation project for the commercial launch of a 2G/3G-femto solution, including delivery of equipment, design, and installation/integration/acceptance testing would last for three to four months, depending on hardware availability (platform/FAPs), lead times, power/space avail-ability, and SIMs availability.At the time of the RFP, all 3G vendors offered proprietary solutions (in terms of the FAP-FGW interface), while most of them stated that commercial availability was expected at the end of 2008 or early 2009. Due to the absence of standards, wide market adoption and economies of scale could not be achieved at that time (lim-ited variety and volume availability of FAPs, lack of homogeneity in terms of supported capabili-ties). 2G-femto solutions are commercially avail-able today by a limited number of suppliers offering their own brands of FAPs.Technology immaturity and unavailability of a fully standardized implementation (based on the Iuh interface), including FAPs from various manufacturers, may strongly affect MOs’ strate-gic decisions regarding solution adoption and time to market.Finally, the operator should not underesti-mate the time required for the preparation and provisioning of commercial offerings, since the provision of femto services is quite different than that of traditional mobile ones.R EGULATORY I SSUESSince femtocells are in essence base stations, public concern regarding the levels of RF radia-tion may appear. According to 3GPP TS25.104, the maximum output power of FAPs should range between 17–20 dBm (without/with trans-mit diversity or multiple-input multiple-output [MIMO]). In addition, FAPs must comply with the guidelines for human exposure to electro-magnetic emissions issued by the International Commission on Non-Ionizing Radiation Protec-tion (ICNIRP) and other relevant regulatory authorities.Given the low output power of FAPs, they could be considered to have the same level of radio frequency (RF) exposure risk as WiFi access points, commonly used in home/office environments, thus facilitating wide market adoption. In this context, MOs could be relieved of reporting (to a regulator) femto base station locations and functional characteristics (e.g.,operating frequency, output power, antennapolarization).V ENDOR/P LATFORM S ELECTIONSimultaneous support of 2G and 3G by the samefemto platform is neither currently supportednor foreseen. As such, an operators’ first choiceshould be between 2G- and 3G-femto alterna-tives. It is worth noting that 2G-femto solutionsaddress the whole subscriber base, thus savingthe operator from replacement/subsidizationcosts; however, a 2G/3G handset owner with suf-ficient 3G coverage at the home/office, uponinstalling a 2G-femto, will no longer enjoy3G/HSPA services, unless a 3G-only network ismanually selected.Femtocell vendor selection takes into accounta plethora of requirements regarding solutionarchitecture, functionality of femto platform andFAPs, range and roadmap/evolution of femtoproducts, NMS/charging/provisioning require-ments, cost efficiency, and vendor experienceand knowledge. An operator’s typical wish listregarding femto platform features may include:•Support of simultaneous voice and data ses-sions•Network access policy (open, closed, groupmode)•Deployment options (same or other PLMN/carrier)•Mobility support (FAP<->2G/3G reselec-tion/handover, FAP<->FAP handover)•Service (voice over data) prioritization•Emergency calls (femto user, all users, pre-emption of a normal call)•Active system presentation (location indica-tion via PLMN-ID, SMS, MM_info, CBS)•FAP auto-configuration (frequency, scram-bling code, CPICH) and self-optimization•FAP lock capability (SIM, FQDN, ADSL,CGI/LAI)•Air interface synchronization (macro net-work, NTP/clock server)•Security and authentication (IPsec IKEv2,EAP-SIM, EAP-AKA, FAP serial numberciphering)•FAP management (remote softwareupgrade, TR-069, fault/performance man-agement)•Auto-fallback to macro in case of failure•Access overload controlHowever, both the RFP and trials indicatedthat as of mid-2008 the femtocell solutions werestill not ready for full-scale commercial deploy-ment. This was justified by the following facts:•The pre-commercial 2G solution trialed didnot support ciphering, closed and groupaccess modes, automatic femtocell plan-ning, a backup mechanism for air interfacesynchronization where no macro coverageexists, macro<->FAP handover, emergencycalls originated from non-femto users,ADSL and macro network (CGI or LAI)lock.6•The majority of 3G vendors did not sup-port: high-capacity FAPs (suitable for enter-prise use), HSUPA, WB-AMR, open andgroup access modes, 2G/3G macro->FAPhandover, FAP<->FAP cell reselectionand handover, user prioritization, active callre-direction to macro, emergency calls forunregistered user, FAP locks (ADSL,FQDN based), self-optimization (incl. SC,frequency and output power), as well asauto-fallback to macro in case of failure,domain specific access control, access/bar-ring, access overload control.•All 3G-femto vendors offered proprietarysolutions with respect to the FAP-FGWinterface (GAN Iu (UMA), proprietaryand/or standard Iu/IP implementation),putting certain restrictions on the varietyand volume availability of FAPs.In addition, we observed differences amongthe vendors’ implementations regarding the fol-lowing features/capabilities:•HSDPA implementation (e.g., dynamicpower allocation or semi-static code alloca-tion, proportional-fair and/or Round-Robinscheduling)•Support of multi-RAB combinations (e.g.,1CS+1PS, 2PS, 1CS+2PS, 3PS, etc. wherePS can be DCH or HS-DSCH)•Authentication (SIM/USIM-based or hard-coded information within a chip)•FAP<->2G/3G macrocell reselection (viaparameterization or HCS)•UL/DL Interference estimation (path lossinformation, CPICH auto-configuration)while major shortcomings may be identified inthe support of macro->FAP handover; arduousmanual definition of every single FAP (FAPCell-ID, RNC-ID, scrambling codes, etc.) in2G/3G macro neighbor lists.Femtocell solutions necessitate the establish-ment of IPsec tunnels between the FAP andFGW over which traffic/signaling/OAM traffic isencrypted, while the IKEv2 and IPsec EAP pro-tocols offer confidentiality. All vendors supportnormal core network authentication proceduresbetween UE and the MSC/HLR. Air interfaceciphering and integrity protection is not support-ed by all FAP manufacturers, but the imperativeto utilize ordinary handsets and UE SIMs forIEEE Communications Magazine • September 2009accessing the FAPs forces them to use ordinary UMTS (Kasumi-based) encryption and integrity protection algorithms UEA1 and UIA1, respec-tively.Access to FAPs can be restricted utilizing closed mode, where selected users/MSISDNs per FAP can be serviced, and/or group mode, where only selected users/MSISDNs may access a cer-tain FAP group. Closed/group modes are not supported by all vendors.Mutual authentication/certification between FAPs and FGWs can be based on dedicated FAP SIM/USIM (EAP-SIM/EAP-AKA),7hard-coded authentication chips built in the FAP, dig-ital certificates stored in FAPs’ SIM, software coded authentication certificates pre-stored in FAPs’ Operating System or MAC addresses.Depending on FAPs capability (embedded SIM,built-in chip, etc.) the operator may be forced to support more than one authentication/certifica-tion options.M ARKETABILITYFor MOs, femtocells constitute an attractive solution for indoor coverage improvement, andmay offload macro network traffic and/or offer inexpensive voice and data services. However,investment in core network infrastructure (and possible FAPs subsidization) is required; macro network planning can be affected, while SLAs may be required to guarantee QoS. End-user benefits may include quality of experience improvements (voice, data), inexpensive voice tariffs within the femto zone, “one-phone-one-number-one-bill,” and the same services indoors and outdoors. The end user, however, is required to pay for a broadband connection to the Inter-net (which s/he may already own) and possibly for the FAP equipment; it depends on the oper-ator’s strategy.The same architectural approach with femto-cells is implemented by UMA/GAN. Although UMA/GAN is considered a mature and com-mercially available standards-based technology,for quite long time, wide market adoption has not been achieved yet since it necessitates the use of purpose-built UMA/GAN handsets.Besides femtocells and UMA, other technolo-gies could be exploited (repeater-like solutions,fixed wireless terminals) presenting similar capa-bilities and functionalities [5, 6]. Although not directly comparable, each solution addresses dif-ferent technical and commercial issues. More specifically:•Repeater-like solutions may boost indoor coverage, for both voice and data, without requiring core network infrastructure.•FWT could be considered as a means to extend indoor coverage for data services only (via WiFi and Ethernet interfaces),while voice/fax services are provided via plain old telephony service (POTS) inter-faces.However, since both solutions reuse macro network resources, network expansions could be envisaged for extensive use. Home-zone tariffing may by applied to both of the above solutions,while — in contrast to femtocells — neither of them is functional in areas with no macro net-work coverage (at least –110 dBm required).C ONCLUSIONSOur as well as other operators’ involvement and experience with pre-standard femtocell solutions has revealed some of their early draw-backs that restrained them from massive-scale commercial launches. However, the accumulat-ed experience from all these trials as well as the recent standardization activities in 3GPP/3GPP2 will lead to a new generation of stan-dardized femtocell solutions and raise the expectation for commercial market success for operators and vendors alike. It is envisaged that initially, femtocells will be utilized for coordi-nated coverage extension purposes (e.g., public areas) and niche markets (high-value customers,enterprise packages), rather than mass market commercial offerings. Upon the advent of stan-dardized 3G-femto solutions, the increase of competition at FAP level (models, volume availability, cost reduction) will contribute to the extensive commercialization of femtocells,which will be further boosted by the introduc-tion of LTE home Node-Bs.R EFERENCES[1] 3GPP TR 25.820, “3G Home NodeB Study Item Techni-cal Re p ort.”[2] 3GPP TS 22.220, “Service Requirements for HomeNodeBs (UMTS) and eNodeBs (LTE).”[3] 3GPP TS 25.467, “UTRAN Architecture for 3G HomeNode B (HNB); Stage 2 UTRAN Architecture for 3G Home NodeB (HNB).”.[4] Femto Forum, “Interference Management in UMTS Fem-tocells,” htt p :///femto/Files/File/Interference_Management_in_UMTS_Femtocells.p df,Dec. 2008.[5] A.
