From the development of the 3G mobile phone market, nearly half of the citizens indicated that they would definitely use 3G services. However, the most critical factor is which operator can provide the fastest internet speed, which may become the main factor for users to choose 3G services. "The Internet has changed human society, and the arrival of mobile Internet will more profoundly affect 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 China Unicom's 3G phone strategies, except for China Mobile's 3G phones which use China's own technical standard and only have TD phones available domestically, there are rarely any tricks involved. Under China Telecom's three-dimensional marketing offensive, the consumer market is full of anticipation for Tianyi 3G internet phones. Domestic and international mobile phone brands are all striving, launching multiple latest CDMA2000 format 3G phones, aiming to seize market opportunities.
Facing the hot trend in the 3G mobile phone market, experts recently reminded that when purchasing a 3G phone, attention should be paid to the adopted technology platform, as different platforms have significant differences in network bandwidth for 3G phones. For example, different CDMA2000 EVDO 3G phones using different technology platforms can have internet speeds that 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 download speed of 2.4Mbps and an upload speed of 153Kbps. The other uses the new generation EV-DO Rev.A platform, where EV-DO Rev.A platform 3G phones support a download speed of 3.1Mbps and an upload speed of 1.8Mbps.
This means that the download 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 upload rate is exactly 12 times that of the EV-DO Rev.0 platform 3G phones. When at theoretical peak, downloading an ordinary MP3 with a 3G phone using the EV-DO Rev.A platform takes only 1-2 seconds, faster than fixed network speeds, making web browsing, software downloads, online videos, and online games much smoother.
Domestic brands mostly adopt EV-DO Rev.A technology, showing obvious advantages. Internationally branded 3G phones currently sold domestically are mostly older models slightly modified for domestic sales, many adopting EV-DO Rev.0 technology. From the already launched CDMA 2000 3G phones, many international brand phones use EV-DO Rev.0 technology. Domestically, recent launches have been mostly EV-DO Rev.0 products, among which Coolpad E200 from Yulong is a representative work of EVDO RevA platform 3G phones. This phone not only has prominent upload and download network transmission speeds but also provides a user-friendly and easy-to-use experience for high-end business professionals, fully supporting China Telecom's Tianyi 3G phone services. In addition, 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 to ensure 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, existing 3G equipment, and nationwide network coverage." Traditional 2G era mobile internet speed can 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. Additionally, its signal will be stronger and more stable, with radiation being only one-tenth of a regular phone."
