Brewing in the next year, 3G telecom Speed: Theoretical speeds up to 9.3Mbps

Informed sources, China Telecom is preparing to upgrade its 3G network again, using the latest version of CDMA 3G technology, will enable 3G speed 3 times faster than now, theoretical downlink speeds of up to 9.3Mbps.

7 upgrades since January testing 3G technology

3G networks currently used by China Telecom is the version of EV-DO Rev.A technology (hereinafter referred to as A version), Theory of rate behavior of 3.1Mbps, but the equipment manufacturers have already developed a version of EV-DO Rev.B technology (hereinafter referred to as the B version), Theory of rate behavior of 9.3Mbps. It is reported that China Telecom is evaluating whether to adopt the version of EV-DO Rev.B technology, will begin testing in July.

The move is mainly Competition between operators due to the rate. China Unicom has announced that its WCDMA network technology used for the downlink maximum speed 14.4 Mbps, WCDMA terminal current rate of 7.2 Mbps, so the current stage of the launch of 7.2 Mbps high speed downlink, which led to China Telecom is also trying to overtake in technology.

Stakeholders also admitted that China Telecom really launched an upgraded version of CDMA 3G technology depends on two conditions: first, whether there is market demand, one is the system equipment and IRF7821TR datasheet and terminals maturity.

It is reported that equipment manufacturers can be released in the fourth quarter of this year, the upgrade version of CDMA 3G equipment, but the terminal will have later. The industry is expected version of Qualcomm chips to B this year out of the fourth quarter, system vendors will be later than three months. This latest 3G CDMA terminals will have to be out next year.

May be the worlds first use

CDMA 3G technology has so far this latest in the world and IRF7821TR price and no carriers, China Telecom Accidentally seems to be the first possible carriers of the latest technology on the global CDMA networking technologies will have a major impact . Therefore, China Telecom in this issue for the industry on how to choose a high degree of attention. At present, China Telecom has not yet finally decided, KDDI in Japan is also considering the matter, it is clear the attitude of China Telecom, KDDI in Japan will also have a significant impact.

Which is a very important decision factor is that in the end will come when LTE, B version of whether the technology will be very brief transitional technology.

Response, the industry believes that "Chinas 3G license issuance and IRF7821TR suppliers and other seven or eight years, who do not know when LTE issued a license. In addition, LTE also need to solve many technical problems, not soon be launched in . LTE large-scale construction until 2012, therefore, before, on the B version of Chinas telecommunications needs.
