Td Terminal First Single Two Million Td / Edge Automatic Switch-td, Mobile, Network - Communications
With the TD-SCDMA network construction under way
, TD-SCDMA terminal part of the industry's focus, especially for China Mobile's network evolution, TD-SCDMA/GSM dual-mode mobile phone program change, from the initial The TD-SCDMA/GSM/GRPS evolved into TD-SCDMA/GSM/GPRS/EDGE. Early in June, days? And NXP announced the two sides together, first in the industry to achieve a TD-SCDMA and GSM / GPRS / EDGE multi-mode automatically switches between voice, which launched at the end of this year for the corresponding way for a commercial solution.TD / EDGE dual-mode out of the fourth quarter of commercial aircraft
Days? Technology CTO, said Dai Jun: "TD-SCDMA and GSM / GPRS / EDGE automatic switching function between the successful, can ensure that the TD-SCDMA mobile phones and 2.5G network, backward compatibility to remove the TD-SCDMA the largest mobile phone technology in the commercial barriers to early. "
NXP Zhuzhao Liang, vice president of China sales, said: "NXP's EDGE solution from the 2004 program delivery, there are already 50 million EDGE mobile phone with the program." Zhang Jun said that the new generation of solutions in the power of and the cost is not higher than TD-SCDMA/GSM/GPRS program.
Present, the switching function has been in Datang Mobile, ZTE and Ding Bridge vendor TD-SCDMA network equipment to achieve. According to reports, the program is based on the ARM9 platform development, ARM9 processor without plug-in. Program to achieve the uplink 128Kbps, 384Kbps downlink transmission rate.
Zhang Jun said on behalf of: "TD / EDGE dual-mode phone will appear in the fourth quarter." And this time generally and Datang Mobile TD / EDGE dual-mode chip solution launched in the same time. Datang Mobile (Shanghai), Liu, vice president of product Tong said: "Datang Mobile will be completed in October beta version at the end of the commercial development."
Time assistant president of Spreadtrum, said: "Now the commercial TD-SCDMA terminal the process is very tight, the Government and operators focus on the tasks assigned us to solve the TD-SCDMA terminals, low power consumption, HSDPA, dual-mode terminal automatic switching problem. These three issues are whether TD-SCDMA terminals guarantee a successful business is something of particular concern to operators. "He further explained that, for dual-mode terminal automatically switch as TD-SCDMA network construction has not yet completely finished, the lack of on-site physical validation conditions are more difficult to achieve them. Therefore, dual-mode terminal chipset TD-SCDMA/EDGE R & D priority will be relatively low, is expected in the fourth quarter.
Dual-mode terminal development, focusing on the design needs of chip makers and terminal manufacturers support. In With the mature, stable design, the device manufacturers can quickly launch the appropriate product.
TD terminal first one about 200 million
Despite news that China Mobile will increase the terminal's input, but industry analysts say, TD-SCDMA terminals of the first order will not be too much, procurement quantity should be around 200 million units. TD-SCDMA terminals of the network testing start in the third quarter, while the bid for the fourth quarter was mainly to see the situation the user experience.
In the three major operators, China Mobile TD-SCDMA network construction to carry out the ten cities, the population reached 7200 million in the first half of this year there are 13,000 base stations have been put into application. According to forecasts that TD-SCDMA users in 2011 will reach 75,000,000. Can be achieved if the true figure, which means TD-SCDMA users in four years the average annual growth rate to more than 100%. TD-SCDMA terminals that preparations be?
ITU Telecom show in the last year, domestic enterprises have a focus on end appearance, ZTE, Hisense, Haier, Yulong, Holley, Inventec, Amoi, Samsung, LG have launched a TD-SCDMA/GSM / GPRS dual-mode terminal.
