CDMA基础知识
掉线率低
基站是手机通话的保障，当用户移动到基站覆盖范围 的边缘时，基站就应该自动"切换"来保障你，否则就 会掉话。CDMA系统切换时的基站覆盖是"单独覆盖 －双覆盖－单独覆盖"，而且是自动切换到相邻较为 空闲的基站上，也就是说，在确认手机已移动到另一 基站单独覆盖地区时，才与原先的基站断开，这样就 保障了手机不会掉话。
三：CDMA技术的优点 技术的优点
1容量增加,是目前流行的GSM的3-4倍 2通话质量大幅度提高,接近有线电话的通话质量 3大大简化小区频率规划,因为所有小区使用相同的频点 4保密性能更强 5手机功耗更小,从而使手机待机时间更长,通话时间更长 6增强小区的覆盖能力,减少基站数目 7不会与现在的模拟和数字系统产生干扰 8 提供可靠的移动数据通信 9可靠的软切换方式大大降低了切换的失败次数

The aim of CPRI is to define a publicly available specification for the key internal interface of radio base stations.As a founder of CPRI, Huawei’s RRU is fully complied with CPRI 1.1 specification, which means operators can have the benefits of cost-effective and high quality from the whole CPRI industry.第二章 CDMA2000第一节展板介绍1.1Global Applications of Huawei CDMA2000Huawei CDMA2000 has been widely applied worldwide in over 50 countries, in Europe, Eastern Europe, CIS region, middle Asia, Asia & pacific, Africa, Middle East, Latin America and north America., such as U.S.A., Mexico, Brazil, Portugal, Romania, Russia, Belarus, Turkmenistan, Kirgizstan, Uzbekistan, Georgia, Azerbaijan, Kazakstan, Ukraine, Thailand, Indonesia, India, Pakistan, Vietnam, Brunei, Yemen, Saudi Arab, Egypt, Algeria, Nigeria, Ethiopia, …. The t otal capacity is c.a. 20 million subscribers. Especially, Huawei is the leading vendor of CDMA450 application with 66% market share worldwide, and 43% market share of CDMA-WLL, 5 commercial EV-DO networks and over 15 DO trial networks.In 2004, American operator (NTCH-CA) selected Huawei as the supplier of her CDMA network. And in the 1st phase, Huawei deployed 2 local networks in California and Arizona in 1900MHz, including SMS & MMS equipments. This is the first time that Chinese telecom vendor supplies CDMA system in United States of America. As we know, CDMA technology is originated from U.S.A. and applied in the first instance, they know CDMA very well, so they understand exactly the keys of CDMA. Huawei passed all the tests via series of excellent features and functions, and then got the first CDMA contract in United States of America.On the project of IUSACELL CDMA2000 network in Mexico, the capacity is 200,000 subscribers to cove 2 areas, section 1 and section 8, there are pairs of sates in each section.In section 1 the system is totally new CDMA2000 system, while in section 8 the system mainly comes from Huawei, the small part is from Motorola. In section 8 the system is at 800MHz frequency, while in section 1 the system is 1900MHz frequency, and the networks are 1X + EV-DO mixed configuration in both section. In phase I, the system is deployed with traditional MSC, and in second phase the SoftSwitch will be deployed. This is a turn-key project including infrastructure, transmission equipments, civil engineering, etc.Huawei provided the first CDMA network in Western Europe, it’s the nationwide CDMA450 network in Portugal, which is 1X + DO mixed network to offer 1X and DO services.CAT is a state-owned telecom operator in Thailand, the existing CDMA system was IS-95 technology provided by Lucent and NEC. The technology is outdated and the revenue was uneasy. So CAT carried out this bidding of CDMA2000 system over the whole country. In this bidding, 5 vendors took part in the bid works, in the phase of technology-evaluate, ZTE and Samsung were washed out. At the end, Huawei is the only vendor for CAT CDMA2000 network. In this network, Huawei will supply 1600 BTS to cover 51 provinces of total 76 provinces in 2 years, including 2.23 million subscribers. And all the BTS is 1X +EV-DO configuration.India is the hottest CDMA market in the world now, the population in India is over 1 billion. And it’s the No.1 CDMA market, so the competition in India is very active. In 2003, through a long time active competition, Huawei got the CDMA contract from MTNL, the capacity is 800,000 subscribers, coverage of Delhi and Mumbai, including OTAF and lawful interception equipments. These two cities are the top 2 biggest cities in India with large areas, dense population and dense buildings. The requirements from operator are very strict and various, Huawei passed all the test items in very short time.Huawei provided IN, CDMA infrastructure and terminals to PTCL in Pakistan. Five local CDMA networks will be distributed in 5 big cities - Islamabad, Lahore, Multan, Quetta and Peshawar, including 1 WIN/SMSC, 1 PDSN, 5 MSC/HLR, 5 BSC, 127 BTS, 305 TRX, BSS capacity is 213K subscribers, NSS capacity is 291k subscribers. Subscribe r’s traffic is 0.05Erl/subscriber. In the second phase of PTCL CDMA network, Huawei got 90% NSS capacity, (SoftSwitch + WIN), NSS capacity is 1275K subscribers (including 400K capacity of CDMA450, 875K capacity of CDMA1900), in 9 areas, total contract is over USD80M. Huawei is the biggest supplier.As you know, roaming is very important for the interconnection of networks. In Belarus, the first International roaming of CDMA450 was carry out on Huawei-built BelCel network and another operator Delta Telecom in St. Petersburg Russia.Huawei deployed its CDMA1900 network for Starcomms in Lagos Nigeria. Lagos is one of the most populated cities in the world. Huawei has provided S444 configured single cabinet BTS to provide dense coverage.In Tibet, CDMA450 network is supplied by Huawei. As we know, the terrain is so crude and hard in Tibet, and very harsh climate there. The nomadic people live in very spread regions. Huawei CDMA450 showed excellent features of coverage and service quality. The system provides telephone service in rural area to offer the nomad a link with the whole socity. In some of the places, before they have CDMA450 system, the people had to walk 6 hours to reach the nearest telephone. The CDMA450 system provides not only telephone services but also great changes of everyday life to Tibetans.1.2 End-to-end solution of Huawei CDMA2000Huawei provides CDMA2000 End-to-End solutions including network infrastructure, service platform, user terminals (inc. handsets and terminals) and after-sales service. The solution may be mobile network or Wireless Local Loop (WLL) system.
