China Mobile LTE terminals are compatible with multi-standard or make wedding clothes for others

4g is accelerating. At the just concluded 2012 Beijing telecommunication exhibition, a number of TD-LTE terminal products were unveiled in China for the first time, and China Mobile also put forward the spectrum requirements for terminals for the first time, that is, they are required to be compatible with five systems: TD-LTE, fdd-lte, GSM, TD-SCDMA and WCDMA

3g era, most manufacturers are not interested in TD system, resulting in the terminal short board that China Mobile can't get rid of. When 4G is approaching step by step, gb/t 5277 ⑴ 985 fasteners, bolts and screw through holes, China Mobile will take the lead in launching multi-mode multi frequency terminals, which will undoubtedly pave the way for it to obtain 4G competitive advantage in China

China Mobile LTE development focuses on multi-mode terminals

China Mobile's growth has slowed significantly in the 3G era. In order to break through the 3G dilemma, China Mobile has been building TD-LTE from network to terminal step by step. In terms of network construction, up to now, China Mobile TD-LTE scale pilot cities have been carried out in 13 cities. China Mobile Hong Kong also announced recently that it will build a seamless dual system integration network of FDD LTE and TD-LTE in Hong Kong

at this year's Beijing Telecom exhibition, China Mobile clearly put forward its requirements for creating a new process mode and frequency in the purchase of LTE terminals for the first time, that is, in the next stage, whether it is the large-scale purchase of data terminals or voice terminals, it is required to support at least five systems: TD-LTE, fdd-lte, GSM, TD-SCDMA and WCDMA. It can be seen that China Mobile plays a multi-mode integration card in the development of terminals

chip is a key factor in the development of terminal industry. For the requirements of multi-mode terminals, at this communication exhibition, all chip manufacturers came up with corresponding products, and focused on the display that the prices of power batteries and four major materials of TD-LTE multi-mode chips will fluctuate greatly. On the booth of TD industry alliance, Spreadtrum showed a TD-LTE chip sc9610, which integrates multi-mode standards in a single chip, including multi band TD-LTE and TD-SCDMA, as well as edge/gs/gprs, which can be used for high-end smart and data cards. Lianxin exhibited multi-mode solutions supporting td-lte/lte fdd/td-hspa/gge, etc

it is reported that China Mobile plans to purchase more than 30000 LTE terminals such as data cards, MiFi, CPE, etc. in 2012, and the supply will be started within the year

terminal multi-mode integration is the development trend

with the continuous evolution of LTE industry over the years, the dual-mode development of TD-LTE and FDD LTE has become the general trend, and the future development of terminals will also move towards the multi-mode era

the value of LTE lies in meeting the needs of high-density data generation areas, and non hotspot areas still need to rely on 3G facilities; LTE does not carry voice service, and voice communication should be decentralized to 2G and 3G. In order to meet the requirements of different operators for voice service support after the introduction of LTE network, the chip needs to support voice solutions, so multi-mode chips must be used

in addition, the communication level of all countries and even the development within a country are uneven. In developed countries such as Europe and the United States, 2G networks have been closed and 4G has quietly arrived. In some countries, 3G development is strong, but there is still a great demand for 2G in many Third World countries and domestic rural areas, and 2G may exist for a long time in the future. In other words, 2G, 3G and 4G will coexist in the future. If LTE terminals want to have roaming capability in different regions and countries, they need to support multiple communication modes and multiple frequency bands, and realize the interconnection of multiple standards. Terminal integration is inevitable

Xi Guohua, chairman of China Mobile, said in June that China Mobile would work with upstream and downstream industries such as system equipment, terminal chips, testing instruments and meters to launch more mature products such as multi-mode integration chips and terminals faster. Li Yue, President of China Mobile, also said at the 2012 world mobile conference held in Barcelona that China Mobile will lead all sectors of the industry to integrate TD-LTE and FDD LTE from standard to industry, including network integration and terminal integration, so that LTE can become a global roaming boutique network

chips are an important part of the terminal industry chain. It is understood that at present, there are 16 domestic and foreign chip manufacturers participating in the research and development of TD-LTE chips, covering all mainstream terminal chip enterprises. All manufacturers plan to support tdd/fddlte integrated chips. It can be seen that multi-mode terminals will be the development trend in the future, and China mobile power multi-mode terminals are based on this

launch multi-mode terminals to take the lead in 4G

since this year, China Mobile has significantly accelerated the pace of LTE construction. In the first half of the year, China Mobile said that in 2012, China Mobile will vigorously promote the integration of TD-LTE and FDD LTE dual-mode multi frequency WiFi terminals, and promote the common development and integration of TD-LTE and FDD LTE dual-mode. Compared with China Mobile's frequent actions on LTE, Chinatelecom and China Unicom seem not to be interested in the construction of LTE. Coupled with China Mobile's efforts to follow the situation, multi-mode terminals will not only complement the terminal shortcomings in the 3G era, but also walk in the forefront of domestic 4G development

the prospect is bright, but the medical electronic Venue: Miss Xiang Yingying, Miss Chai Zhangfan: +86 21 - 155, 502 China Mobile will also face many problems while leading the development of domestic 4G. With the development of mobile Internet, network has gradually become the key for operators to successfully operate data traffic. At the moment when 2G, 3G and even quasi 4G coexist, how to manage data traffic well is a serious problem that China Mobile will face

in terms of multi-mode interoperability, there is still a lot of testing and verification work to be done. Multimode LTE intelligence generally requires 3G chips and LTE baseband chips, and such an architecture poses a great challenge to power optimization. How to solve this problem tests the ability of chip enterprises, and will indirectly affect the experience of LTE terminals. The most realistic thing is that if TD-LTE in the future repeats the mistakes of TD-SCDMA today, the multi-mode terminal of China Mobile may become someone else's wedding dress
