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 here 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, even changing people's lifestyles. To take the lead in the 3G era, the basic construction of the 3G network has become the 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 due to China's own technical standards, only China has TD phones, so there are rarely any tricks. Under China Telecom's three-dimensional marketing offensive, the consumer market is full of expectations for Tianyi 3G internet phones. Domestic and foreign mobile phone brands are making efforts, launching multiple latest CDMA2000 format 3G phones, aiming to seize the market advantage. Faced with the hot market of 3G phones, experts recently reminded that when purchasing a 3G phone, attention should be paid to the technology platform used, as there is a huge difference in network bandwidth between different platforms. 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 EV-DO Rev.A platform, where EV-DO Rev.A platform 3G phones support a downlink speed of 3.1Mbps and an uplink speed of 1.8Mbps. That is to say, 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 the EV-DO Rev.0 platform 3G phones. When downloading a regular MP3 at the theoretical peak with EV-DO Rev.A platform 3G phones, it takes only 1-2 seconds, faster than fixed network speeds, allowing smoother web browsing, software downloads, online videos, and online gaming.
Domestic brands mostly adopt EV-DO Rev.A technology, with significant advantages. International brands currently selling CDMA 3G phones domestically are mostly products already launched overseas, slightly modified for domestic sales, adopting EV-DO Rev.0 technology. From the currently available CDMA 2000 3G phones, many international brand phones adopt EV-DO Rev.0 technology. In contrast, from domestic manufacturers, the recently launched models are mostly EV-DO Rev.0 products. Among them, Yulong Coolpad's Coolpad E200 is a representative work of EVDO RevA platform 3G phones, not only having prominent uplink and downlink network transmission speeds but also providing a user-friendly and easy-to-use experience for high-end business people, fully supporting China Telecom's Tianyi 3G phone services. Additionally, ZTE's D90+ is also an EVDO RevA platform 3G phone.
Consumers who require higher performance for 3G phone internet functions 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 the 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. Moreover, its signal will be stronger and more stable, with radiation only one-tenth of that of ordinary phones."
