The development prospect of 3g technology: Talking about the development prospect of three 3G technologies in the world.
At present, there are three kinds of 3G technologies in the world, WCDMA, CDMA2000 and TD-CDMA. The three technologies have different development prospects in the world because of their different launch dates and different standards supported by different countries.
1.Development of WCDMA
WCDMA mainly originated from the early third-generation wireless research activities in Europe and Japan. At present, there are four versions of WCDMA standard, among which the R99 version has reliable complete sets of equipment and an operational network that can be adopted. The data service provision ability of this version is not as good as that of CDMA2000 lx EV-DO, and the service provision ability of the terminal is weak. R4 version is a transitional version to full packet evolution, and R5 and R6 are both packet networks. In R5, a scheme of high-speed downlink packet access (HSDPA) is proposed, which can make the downlink rate as high as 10 Mbit/s, and the standard is still being worked out.
From the development trend, WCDMA is the dominant technology of 3G at present, with a strong development momentum. By the end of July this year, 82 WCDMA networks have been commercialized in 37 countries, 22 of which appeared in 2005, and 7 networks will soon join this camp. According to the survey, at present, the global WCDMA/HSDPA terminal products have reached 186 models, which are provided by 26 suppliers, among which 70 new terminals have been launched by merchants in the past six months.
Although the 3G license in China has not been issued, many domestic operators have expressed their interest in WCDMA. It is said that most domestic operators will choose WCDMA system. China Mobile is most likely to choose WCDMA, because WCDMA system can be set up on the existing GSM network, so the transition will be more convenient. China Telecom also stopped testing TD-SCDMA technology and turned to WCDMA technology. Moreover, it is understood that China Tietong and China Telecom have built several WCDMA-based base stations, which have been put into the ongoing 3G remote test.
At present, the commercialization process of WCDMA standard based on Europe is accelerating. Five operators, including Austria, Japan and Finland, have announced the launch of 3G services based on WCDMA technology. Li Ka-shing's Hutchison Whampoa is making great strides in 3G, and Britain's WCDMA-based H3G and Italian H3G will be launched soon.
According to the prediction of EMC, an authoritative global telecom and mobile market research and consulting company, the number of global mobile phone users will reach 654.38+06 billion in 2005. Among them, 80%-85% of users are GSM and WCDMA users, including PDC and TDMA users who are switching to GSM/WCDMA, and 10%- 15% are CDMA2000 users.
It can be seen that WCDMA has taken the lead in commercialization.
2.2. Development trend. CDMA2000 standard technology
CDMA2000 is the name used by TIA standard organization to refer to the third generation CDMA. The TIA specification suitable for 3G CDMA is IS-2000, and the technology itself is CDMA2000.
There are several versions of CDMA2000 standard. At present, CDMA2000 standard is based on Ro version and has evolved into EV-DO and EV-DV standards. The EV-DO standard has been commercialized, and there are Ro and Ra versions, among which Ro is relatively mature, and the maximum uplink and downlink rate of a single carrier can reach 153.6 KBit/s..Ra is an enhancement of Ro, but it is not yet mature. The highest single carrier rate can reach 307.2 kbit/s, which supports the concurrency of voice services and packet services. There are Rc and Rd versions of EV-DV standard, and the version standard has been determined. However, the base station and terminal chip of EV-DVRd version are expected to be launched at the end of 2004, and it is estimated that the equipment will not be supported until 2005.
By September 2004, 98 networks in 46 countries around the world had provided commercial 3G CDMA2000 services, with the number of users reaching1.65,438+0.26 billion.
In North America, CDMA*** has 64.5 million users and is the dominant mobile phone technology in this region. In March 2003, more than half of North American users adopted CDMA technology. There are 36 CDMA operators in Canada and the United States, of which 16 has started or is ready to switch to CDMA2000.
In Asia, Japan and South Korea, CDMA2000 1X is a successful business model. In the Japanese market, KDDI launched the third generation mobile phone service "CDMA20001X" using CDMA 2000 technology in 2002, and the total number of users reached150,000 on July 20th this year.
The research and development of CDMA2000 system equipment technology is the fastest in the current standards, and many 3G mobile phones are introduced first.
3.3. Development trend. TD-SCDMA standard technology
TD-SCDMA has become the fastest developing international 3G standard. After being integrated into the R4 standard of 3GPP, TD-SCDMA also participated in the improvement and update of R5 and R6 standards of 3GPP. At present, three experimental networks have been built in Beijing, Chengdu and Chongqing. The test results show that TD-SCDMA system initially has the independent networking capability covering the whole country. At the same time, TD-SCDMA also participated in the first and second phases of the Mobile Simulation Test Network (MTNet) of the Ministry of Information Industry. All indicators have basically passed, and the overall equipment operation of the system is basically stable.
TD-SCDMA standard system equipment technology is unique, and it has a huge market in China. This standard has attracted the attention of major telecom equipment manufacturers. The core network is invested by Nortel, ZTE, Siemens, Huawei, Putian and Alcatel. In terms of access network, Datang, ZTE, Putian, UT, Huawei, Siemens and other manufacturers are vigorously promoting the industrialization process of TD-SCDMA.
The research and development of TD-SCDMA terminal is integrated by 9 manufacturers including China Electronics, Southern Hi-Tech, Hisense and Samsung. European and American manufacturers are also moving closer to TD-SCDMA. Not only Siemens, Samsung and Philips in the early days, but Motorola and Nokia also indicated that they will produce TD-SCDMA mobile phones. At the end of March this year, Datang Mobile successfully developed the world's first TD-SCDMA mobile phone code-named DTM800l, marking a major breakthrough in the research and development of TD-SCDMA terminals and a step towards large-scale commercialization.
At present, TD-CDMA of Datang 3G is said to have reached the requirements of 3G, and it is estimated that 3G has dawned in China. However, the industry generally believes that the market positioning of TD-SCDMA should be better tied with WCDMA, so that there will be room for development in the world.
