From the development of the 3G mobile phone market, nearly half of the citizens have expressed that they will definitely use 3G services. However, the most crucial factor is which operator can provide the fastest internet speed, which could become the main factor for users to choose 3G services. "The Internet has changed human society, and the arrival of mobile Internet will inevitably have a more profound impact on people's lives, possibly even changing their lifestyles. In order to lead in the 3G era, the basic construction of 3G networks has become the top priority work. Now, whether it is China Telecom's 3G mobile phones or China Mobile and China Unicom's 3G mobile phone strategies, except for China Mobile's 3G phones which use China's own technical standards and only TD phones are available in China, there are rarely any tricks. Under China Telecom's three-dimensional marketing offensive, the consumer market is full of expectations for the 3G Internet mobile phones of Tianyi. Domestic and foreign mobile phone brands are all making efforts, successively launching multiple latest CDMA2000 format 3G mobile phones, aiming to gain the market advantage. Faced with the hot market situation of 3G mobile phones, recently experts have reminded that when purchasing 3G mobile phones, one should pay attention to the technology platform used, as different platforms have huge differences in network bandwidth for 3G mobile phones. For example, different CDMA2000 EVDO 3G mobile phones use different technology platforms, and the highest 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 mobile 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 EV-DO Rev.A platform 3G mobile phones support a downlink speed of 3.1Mbps and an uplink speed of 1.8Mbps. That is to say, the downlink rate of 3G mobile phones using the EV-DO Rev.A platform is 1.3 times that of 3G mobile phones using the EV-DO Rev.0 platform, while the uplink rate is exactly 12 times that of 3G mobile phones using the EV-DO Rev.0 platform. When downloading an ordinary MP3 at the theoretical peak, 3G mobile phones using the EV-DO Rev.A platform can download in just 1-2 seconds, faster than fixed-line internet speeds. Whether it is web browsing, software downloads, online videos, or online games, these phones perform much more efficiently.
Most domestic brands use EV-DO Rev.A technology, showing obvious advantages. Internationally branded mobile phones currently sold domestically are mostly products already launched overseas earlier, slightly modified for domestic sales, and mostly use EV-DO Rev.0 technology. From the already listed CDMA 2000 3G mobile phones, many international brand phones use EV-DO Rev.0 technology. As for domestic manufacturers, most of the newly listed products are EV-DO Rev.0 products. Among them, Coolpad E200 from YuLong Coolpad is a representative work of EVDO RevA platform 3G mobile phones. This model not only has prominent uplink and downlink network transmission speeds but also provides a humanized and easy-to-use control experience for high-end business professionals, fully supporting China Telecom's Tianyi 3G mobile phone services. Additionally, ZTE's D90+ and others are also EVDO RevA platform 3G mobile phones.
If consumers have higher requirements for the application of 3G mobile phone internet functions, they should try to choose EVDO Rev.A platform 3G mobile phones to ensure high transmission rates of the 3G network from the terminal hardware, thereby enjoying a more genuine 3G internet function experience.
For China Telecom's Tianyi mobile phones, the biggest advantage lies in the existing network, existing 3G equipment, and a nationwide coverage network. "In the traditional 2G era, the mobile phone internet speed could only be guaranteed around 150Kbps, but after the 3G network is built, the internet speed of Tianyi 3G mobile phones can reach 3.1Mbps, meaning it is 20 times faster than the current mobile phone internet speed. Moreover, its signal will be stronger and more stable, with radiation only one-tenth of that of regular mobile phones."
