From the development of the 3G mobile phone market, nearly half of the citizens expressed that they would definitely use 3G services. The most critical factor is which operator can provide the fastest internet speed, which may become the primary factor for users to choose 3G services. "The Internet has changed human society, and the arrival of mobile Internet will more profoundly impact people's lives, even changing their lifestyles. To lead in the 3G era, the basic construction of the 3G network has become a top priority. Now, whether it's China Telecom's Tianyi 3G phones, or China Mobile and Unicom's 3G phone strategies, aside from China Mobile's 3G phones using China's own technical standards, only China itself has TD phones, so there are rarely any tricks. Under China Telecom's three-dimensional marketing offensive, the consumer market is full of anticipation for Tianyi 3G internet phones. Domestic and foreign mobile phone brands are all making efforts, launching multiple latest CDMA2000 format 3G phones, aiming to seize the market advantage. Faced with the hot trend of the 3G mobile phone market, recently experts have reminded that when purchasing a 3G phone, attention should be paid to the technology platform used, as different platforms have significant differences in network bandwidth for 3G phones. For example, different CDMA2000 EVDO 3G phones use different technology platforms, and the internet speed can differ by up to 12 times.
EV-DO Rev.A platform phones have obvious advantages. Currently, there are two camps for CDMA2000 format 3G phones. One uses the EV-DO Rev.0 platform, supporting a downlink speed of 2.4Mbps and an uplink speed of 153Kbps. The other uses the new generation EV-DO Rev.A platform, where the EV-DO Rev.A platform 3G phone supports a downlink speed of 3.1Mbps and an uplink speed of 1.8Mbps.
In other words, the downlink rate of 3G phones using the EV-DO Rev.A platform is 1.3 times that of 3G phones using the EV-DO Rev.0 platform, while the uplink rate is exactly 12 times that of 3G phones using the EV-DO Rev.0 platform. When downloading a regular MP3 at the theoretical peak speed, it takes only 1-2 seconds, faster than fixed-line internet speeds. Whether it's web browsing, software downloads, online videos, or online games, it performs much more efficiently.
Domestic brands mostly adopt EV-DO Rev.A technology, with obvious advantages. Internationally branded CDMA 3G phones currently sold domestically are mostly products already launched overseas, slightly modified for domestic sales, mostly using EV-DO Rev.0 technology. From the already released CDMA 2000 3G phones, many international brand phones use EV-DO Rev.0 technology. From the domestic manufacturers' perspective, most recent releases are EV-DO Rev.0 products. Among them, Coolpad E200 by Yulong is a representative work of EVDO RevA platform 3G phones, not only featuring outstanding uplink and downlink network transmission speeds but also providing a humanized and easy-to-use control experience for high-end business professionals, fully supporting China Telecom's Tianyi 3G phone services.
Additionally, ZTE's D90+ is also an EVDO RevA platform 3G phone. If consumers have higher requirements for the application of 3G phone internet functions, they should try to choose EVDO Rev.A platform 3G phones, ensuring high transmission rates of the 3G network from the terminal hardware, thus enjoying a more genuine 3G internet function experience.
For China Telecom's Tianyi phones, the biggest advantage lies in its existing network, ready-made 3G equipment, and nationwide coverage. In the traditional 2G era, mobile internet speed could only guarantee around 150Kbps, but after the 3G network is built, the internet speed of Tianyi 3G phones can reach 3.1Mbps, meaning it is 20 times faster than the current mobile internet speed. Moreover, its signal will be stronger and more stable, with radiation only one-tenth of that of ordinary phones."
