mobile and cellular radio移动和细胞广播in comparison to the relative stability and modest technical developments which are occurring in long haul wideband microwave communication systems there is rapid development and expanding deployment of new mobile personal communication system. These rang from wide coverage area pagers,for simple data message transmission,which employ common standards and hence achieve contiguous coverage over large geographical areas,such as all the major urban centres and transport routes in Europe,Asia or the continental USA.This chapter discusses the special channel characteristics of mobile systems and examines the typical cellular clusters adopted to achieve continuous communication with the mobile user.It then highlights the important properties of current,and emerging,TDMA and code division multiple access(CDMA), mobile digital cellular communication systems.Private mobile radioTerrestrial mobile radio works best at around 250 MHz as lower frequencies than this suffer from noise and interference while higher frequencies experience multipath propagation from buildings,etc,section 15.2.In practice modest frequency bands are allocated between 60MHz and 2GHz. Private mobile radio(PMR) is the system which is used by taxi companies,county councils,health authorities,ambulance services,fire services,the utility industries,etc,for mobile communications.PMR has three spectral at VHF,one just below the 88 to 108 MHz FM broadcast band and one just above this band with another allocation at approximately 170MHz.There are also two allocations at UHF around 450MHz. all these spectral allocations provide a total of just over 1000 radio channels with the channels placed at 12KHz channel spacings or centre frequency offsets. Within the 12khz wide channal the analogue modulation in PMR typically allows 7khz of bandwidth for the signal transmission.when further allowance is made for the frequency drift in the oscillators of these systems a peak deviation of only 2 to 3 khz is available for the speech traffic. Traffic is normally impressed on these systems by amplitude modulation or frequency modulation and again the receiver is of the ubiquitous superheterodyne design,Figure 1.4. A double conversion receiver with two separate local oscillator stages is usually required to achieve the required gain and rejection of adjacent channel signals.One of the problems with PMR receiver is that they are requiredto detect very small signals,typically—120dBm at the antenna output,corresponding to 0.2 uV,and,after demodulating this signal,produce ann output with perhaps 1W of audio equipment, the first IF is normally at10.7MHz and the second IF is very orten at 455KHz . unfortunately,with just over 1000 available channels for the whole of the UK and between 20000and30000issued licences for these systems,it is inevitable that the average busuness user will have to share the allocated channel with other companies in their same geographical area.There are various modes of operation for mobile radio communications networks, the simplest of which is singal frequency simplex. In simplex communication, traffic is broadcast, or one way. PMR uses half duplex(see later Table 15.3) where, at the end of each transmission period, there is a handover of the single channel to the user previously receiving, in order to permit them to reply over the same channel. This is efficient in that it requires only one frequency allocation for the communication link but it has the disadvantage that all units canhear all transmissions provided they are within rage of the mobile and frequencies are allocated for the transmissions. One frequency is used for the forward or downlink, namely base-to-mobile communications. This permits simultaneous two-way communication and greatly reduces the level of interference, but it halves other’s transmissions, which can lead to contention with two mobiles attempting to initiate a call, at the same time, on the uplink in a busy syetem.Although PMR employs relatively simple techniques with analogue speech transmission there have been many enhancements to these systems over the years . Data transmission is now in widespread use in PMR systems using FSK modulation. Data transmission also allows the possibility of hard copy graphics output and it gives direct access to computer services such as databases, etc. Data prembles can also be used, in a selective calling mode, when initiating a transmission to address a special receiver and thus obtain more privacy within the system.15.4.5 Trunked radio for paramilitary use集群无线电的军事使用Another related TDMA mobile radio standard is the European trunked radio(TETRA)network which has been developed as part of the public safety radio communications service(PSRCS) for use by police, utilities, customs office, etc. TETRA in fact is part of wider international collaborations for paramilitary radio use.In these portable radios there is a need for frequency hopping (FH) to give an antieavesdropping capability and encryption for security of transmission to extend military mobile radio capabilities to paramilitary use, i.e. for police, customs and excise offices, etc. these capabilities are included in the multiband interteam radio for the associated public safety communications office in the USA while Europe has adopted the TETRA standard.TETRA is essentially the digital TDMA replacement of the analogue PMR systems. The TETRA standard has spectrum allocations of 380 to 400 and 410 to 430MHz, with the lower band used for mobile transmissions and the upper band for base station use. TETRA mobile have 1 W output power and the base stations 25 W using error with the data throughput rate varying, to meet the required quality of service. TETRA can accommodate up to four users each with a basic speech or data rate of 7.2kbit/s. with coding and signaling overheads, the final transmission rate for the four-user slot is 36 kbit/s. this equipment is large and more sophisticated than a commercial cell phone, and it sells for a very much higher price becase the production runs are much small. However, its advanced capabilities are essential for achieving paramilitary communications which are secure from eavesdropping.15.5 Code division multiple accessAnalogue communication systems predominantly adopt frequency division multiple access (FDMA), where each subscriber is allocated a narrow frequency slot within the available channel. The alternative TDMA(GSM) technique allocates the entire channel bandwidth to a subscriber but constrains the subscriber but constrains the subscriber to transmit only regular short bursts of wideband signal. Both these accessing techniques are well established for long haulterrestrial, satellite and mobile communications as they offer very good utilization of the available bandwidth.15.5.1The inflexibility of these coordinated accessing techniques has resulted in the development of new systems based on the uncoordinated spread spectrum concept. In these systems the bits of slow speed data traffic from each subscriber are deliberately multiplied by a high chip rate spreading code, forcing the low rate (narrowband data signal) to fill a wide channel bandwidth.15.7.2 3G systemsThe evolution of the third generation (3G)system began when the ITU produce the initial recommendations for a new universal mobile telecommunications system(UMTS)[www.] The 3G mobile radio service provides higher data rate services ,with a maximum data rate in excess of 2Mbit/s, but the achievable bit rate is linked to mobility. Multimedia applications encompass services such as voice, audio/video, graphics, data, Internet access and e-mail. These packet and circuit switched services have to be supported by the radio interface and the network subsystem.Several radio transmission technologies(RTT) were evaluated by the ITU and adopted into the new standard, IMT-2000. the European standardization body for 3G, the ETSI Special Mobile Group, agreed on a radio access scheme for 3G UMTS universal terrestrial radio access(UTRA) as an evolution of GSM. UTRA consists of two modes : frequency division duplex(FDD) where the uplink and downlink are transmitted on different frequencies; and time division duplex(TDD) where the uplink and downlink are time multiplexed onto the same carrier frequency. The agreement assigned the unpaired bands (i.e. for UTRA TDD ). TD-CDMA is a pure CDMA based system. Both modes of UTRA have been harmonised with respect to basic system parameters such as carrier spacing, chip rate and frame length to ensure the interworking of UTRA with GSM.The 3G proposal were predominantly based wideband CDMA(WCDMA) and a mix of FDD and TDD access techniques. WCDMA is favoured for 3G in poor propagation environments with a mix of high modest speed data traffic. It is generally accepted that CDMA is the preferred accesstechnique and, with the increase in the data rate, then the spreading modulation needs to increase to wideband transmission.WCDMA is based on 3.84Mchip/s spreading codes with spreading ratio, i.e. , K values, of 4-256 giving corresponging data ratas of 960-15 kbit/s. the upper FDD uplink band I from 1920-1980 MHz is paired with a 2110-2170 MHz downlink. In addition uplink bands II & III at 1850-1910 MHz and 1710-1785 MHz are also paired, respectively, with 1930-1990 MHz and 1805-1880 MHz allocations. the system is configured on a 10 ms frame with 15 individual slots to facilitate TDD as well as FDD transmissions. TDD is more flexible as time-slots can be dynamically reassigned to uplink and downlink functions, as required for asymmetric transfer of large files or video on demand traffic. 3G WCDMA systems use an adaptive multirate speech coder with encoded rates of 4.75-12.2 kbit/s. receivers commonly use the easily integrated direct conversion design, in place of the superheterodyne design . receiver sensitivities are typically -155dBm.The 3GPP2 standard aims to achieve a wide area mobile wireless packet switched capability with CDMA2000 1×EV DO revision A (sometimes called IS-856A). Here 1×refers to the single carrier 1.25 Mchip/s system. It achieves a 3.1 Mbit/s downlink and a delay sensitive services. The 3GPP standard has gone through many release with R4 in 2001 which introduced packet data services and R6 in 2005 to further increase the available data transmission rate . R6 pioneers the use of high-speed downlink packet access and multimedia broadcast multicast services which offer reduced delays and increased uplink data rates approaching 6 Mbit/s.In parallel with the European activities extensive work on 3G mobile radio was also performed in Japan. The Japanese standardisation body also chose WCDMA, so that the Japanese and European proposals for the FDD mode were already aligned closely. Very similar concepts have also been adopted by the North American standardization body.In order to work towards a global 3G mobile radio standard, the third generation partnership project(3GPP), consisting of members of the standardization bodies in Europe, the USA, Japan, Korea and China, was formed. It has merged the already well harmonized proposals of the regional standardization bodies to work on a common 3G international mobile radio standard, still called UTRA. The 3GPP Project 2(3GPP2), on the other hand, works towards a 3G mobile radio standard based on cdmaOne/IS-95 evolution, originally called CDMA2000.比起相对稳定、适度的技术发展是发生在宽带微波通信系统,有长期快速发展和扩大部署的新的移动个人通讯系统。

科技英语新闻翻译MARGIE NEWMAN: "When you can go to a place and not only see what's next and see how to better use what's already here, but also connect with people who love it as much as you do, it's just kind of a special thing. A lot of people call South by Southwest Interactive the geek spring break. And that's pretty accurate."纽曼：“当你来到这里，不仅能看到下一个技术热点，了解如何更好的运用当前科技。
还可以和有着相同兴趣的人一起交流。
这是非常特别的经历。
很多人把SXSW盛典称为奇客春假（怪人云集），这是相当准确的。
South by Southwest Interactive has seen the successful launch of several products. It helped push Twitter into mainstream popularity in two thousand seven. In two thousand nine, a company called Foursquare launched its mobile networking service at the festival. The service lets friends tell other friends where they are by "checking in" using a mobile application or a text message. Foursquare's owners say they now have more than six and a half million users around the world.SXSW盛典见证了几个产品的成功推出。
2007年该盛典推动了Twitter的普及。
2009年，一家名为Foursquare的公司在SXSW盛典推出了手机网络服务。
这项服务允许朋友之间通过手机程序或短信“检入”（checking in）分享自己所处的地理位置。
Foursquare公司表示，现在他们在全球拥有超过650万用户。
Margie Newman says quick response codes are big news at this year's festival. The codes turn URLs and text into barcode-like images that can be scanned using a mobile phone or a QR code reader.出自VOA Special English Technology ReportA shortwave radio might seem like ancient technology these days. But for some people, it remains their only link to the wider world.短波收音机如今看来可能像是一种很古老的技术。
但对一些人来说，短波收音机仍是他们与外界联系的唯一工具。
Ears to Our World is an organization based in the United States. It provides shortwave radios to schools and communities in some of the poorest areas of the world.“聆听世界”（Ears to Our World）是一家总部位于美国的组织。
该组织为世界上一些最贫穷地区的学校和社区提供短波收音机。
The radio is small, about the size of a book, and self-powered. Users turn a crank. Winding it for two minutes provides about forty minutes of listening time.这种收音机体积非常小，只有一本书大小。
收音机自身可以发电，用户打开发电手柄摇转2分钟，就能提供40分钟的收听时间。
Ears to Our World is supported by private donations and partners including Eton, the company that makes the Eton Grundig radios.“聆听世界”由私人捐助的支持，其合作伙伴包括制造根德（Grundig）收音机的伊顿公司。
Thomas Witherspoon started Ears to Our World in two thousand eight.托马斯·威瑟斯朋2008年创办了“聆听世界”组织。
THOMAS WITHERSPOON: "Our radios are going to people who have no other source of international news and information. It's hard for them to learn new languages and be connected to the bigger world.威瑟斯朋：“我们的收音机提供给了没有渠道获取国际新闻资讯的人们。
对他们而言，学习新语言并和世界保持联系非常困难。
"In fact, in a lot of these communities, the feedback we get is before they had their radio, most of their news and information came word of mouth, from other people. So this way they're getting more accurate information. And teachers use this information in the classroom to enhance a student's learning ability about the world around them."“事实上，我们从大部分社区得到的反馈信息是，在他们得到收音机以前，他们大部分新闻资讯是通过他人之口传来的。
因此通过收音机他们能得到更多确切信息。
而老师们也能在课堂上利用这些信息，增强学生们对周边世界的学习能力。
”Ears to Our World works with local organizations to get the radios to where they are needed most. Mr. Witherspoon says the radios are now in eleven communities, most of them in Africa.“聆听世界”组织与当地组织合作将收音机送到最需要的地方。
威瑟斯朋先生说，这些收音机现在提供给了11个社区，这些社区大部分在非洲。
He says many of these communities are unable to get information any other way.他说，这些社区中的大多数无法通过其他方式获得信息。
THOMAS WITHERSPOON: "We take our radios to parts of the world that lack access to the Internet, to a national power gridof any sort. We're talking about places maybe in South Sudan that are very, very remote. No one in the community or the village has power in their homes."威瑟斯朋：“我们把收音机送到了世界上部分没有互联网和任何电力网的地区。
我们提到的也许就在南苏丹非常、非常遥远的地区。
这些社区或村庄的人们家里都没有电。
”Thomas Witherspoon says information is the most important tool to improve the lives of poor people.威瑟斯朋表示，信息是改善穷人生活最重要的工具。
THOMAS WITHERSPOON: "In this economy, information is sort of the lifeline for all of us to function and get along. Especially if you're living in a place where you have no information, information is your way out of poverty."威瑟斯朋：“在当今经济环境中，信息是我们所有人工作与生活的生命线。
特别是在缺乏信息的地区，信息是人们的脱贫途径。
”The self-powered radios are also useful in emergencies. Teachers in Haiti used them to get information after last year's earthquake.这种自供电收音机在紧急情况下也非常有用。
海地的老师们在去年的地震后就使用这种收音机获取信息。
Mr. Witherspoon says Ears to Our World has sent out about one thousand two hundred radios. More than half have gone to earthquake victims, mostly in Haiti. About five hundred have gone to individual teachers and schools.威瑟斯朋先生说，“聆听世界”组织已经发放了大约1200台收音机。
