TD-LTE market add fuel to the flames and manufacturer design brilliant a great deal of slice group test under the multiple factor of quantity in the intersection of bottom layer and the intersection of technology and close, China, the intersection of integration and step that crystal plate design more and more fast, including Sequans, Beceem, and Wavesat unite, send department,etc., have already introduced or planned to develop towards goal of this integration.

WiMAX the intersection of crystal plate and loud factory Sequans introduce first LTE crystal plates SQN3010 too, China Mobile has already adopted the crystal plate of Sequans, apply to TD-LTE crystal plate and USB wireless network card. The show of TD-LTE router will appear at World Expo 2010 Shanghai of May for the first time.

Sequans is cooperating with big factory Motorola and Alcatel-Lucent of the telecommunication equipment, promotes the development of China Mobile in TD-LTE USB wireless network card together. This crystal plate is based on 3GPP R8 specification, can support 100Mbps transmission capacity of descenting of CAT-3, mainly take 2.3- 2.4GHz frequency band as the core. Sequans offers LTE solution to Asia and European TD-LTE router operator too and on Alcatel-Lucent cooperative programme, the frequency band in 2.6GHz, the relevant content will be shown in World Expo 2010 Shanghai together too.

It is not unique, WiMAX crystal plate big factory Beceem already in Palestinian Theron has received the communication exhibition of the action of the world (2010) too ,Announce a integration LTE and WiMAX technical multimode crystal plate, the transmission rate reachable 150Mbps of descenting, accord with the intersection of CAT-4 and the intersection of device and standard, it is estimated, come out will it be four seasons this year, begin batch productino the second quarter of next year. What merits attention is, this crystal plate can be according to the needs of actual transmission symmetrical ((paired) )Frequency demultiplication multiplexing (Time Division Duplex; TDD) And unsymmetry (unpaired) Time Division Multiplexing (Time Division Duplex; TDD) During change. The ones that adopt oneself to develop in this are multimode to respond to the function oneself, borrow it by the router type of automatic detection, to choose appropriate frequency band transmission again immediately.

Wavesat put out brilliant slice group Odyssey 9000 too last October, also possessed CAT-3 (100Mb/s descented, 50Mb/s up run) Transmission capacity, can also be compatible with WiMAX. Another WiMAX crystal plate manufacturer Israeli Altair Semiconductor, introduced the fundamental processor scheme too last year, also accord with CAT-3 brilliant slice group transmitting capacity. In addition, had united and taken place the department and already introduced WiMAX crystal plate to the new developing market last year and planned to introduce TD-LTE crystal plate again this year, the way of integration should be not far too.

The manufacturer that has already introduced the crystal plate sample at present includes Samsung, Altair Semiconductor, BitWave Semiconductor, Comsys Mobile, Infineon, Qualcomm, ST-Ericsson, LG and Wavesat,etc., add Beceem, Sequans, and estimate Chiang Kai-shek's majestic Rui's news report of sending subject and Weisheng of antithetical couplet of developing TD-LTE crystal plate, there are 13 manufacturers or plan to introduce LTE crystal plate, among them is expected to have 4 factories to develop towards WiMAX integration LTE crystal plate in Shang Dynasty. Though these manufacturers do not all have clear batch productino plan and time table, the first wave that the wireless network card should be WiMAX +LTE employs the focus.
