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 could become the primary reason for users to choose 3G services. "The Internet has changed human society, and the arrival of mobile Internet will more profoundly influence people's lives, even changing their lifestyle. To lead in the 3G era, the basic construction of the 3G network has become a top priority. Now, whether it is 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 standard (TD-SCDMA), only China itself has TD phones, so there are fewer tricks involved. Under China Telecom's multi-dimensional marketing offensive, the consumer market is full of anticipation for Tianyi's 3G internet phones. Domestic and international phone brands are making efforts, launching multiple latest CDMA2000 format 3G phones, aiming to seize the market first.
Faced with the hot market conditions of 3G phones, experts have recently reminded that when purchasing a 3G phone, one should pay attention to the technology platform used, as there are significant differences in network bandwidth among different platforms. For example, different CDMA2000 EVDO 3G phones use different technology platforms, and the maximum internet speed can differ by up to 12 times.
EV-DO Rev.A Platform Phones Have Obvious Advantages
Currently, CDMA2000 format 3G phones are divided into two camps: one uses the EV-DO Rev.0 platform, supporting download speeds of 2.4Mbps and upload speeds of 153Kbps; the other uses the newer EV-DO Rev.A platform, where the EV-DO Rev.A platform supports download speeds of 3.1Mbps and upload speeds of 1.8Mbps.
This means that the download rate of EV-DO Rev.A platform 3G phones is 1.3 times faster than those using the EV-DO Rev.0 platform, while the upload rate is exactly 12 times faster. When at theoretical peak, downloading an ordinary MP3 with an EV-DO Rev.A platform 3G phone takes just 1-2 seconds, faster than fixed network speeds. Whether it's web browsing, software downloads, online videos, or online games, these phones perform much better.
Domestic Brands Mostly Use EV-DO Rev.A Technology, Showing Significant Advantages
International brands currently selling CDMA 3G phones domestically are mostly older models slightly modified for sale in China, many adopting EV-DO Rev.0 technology. From the already launched CDMA 2000 3G phones, quite a few from international brands use EV-DO Rev.0 technology. In contrast, domestic manufacturers have recently launched more EV-DO Rev.0 products. Among them, Coolpad E200 by Yulong is a representative work of EVDO RevA platform 3G phones, not only having outstanding upload and download network transmission speeds but also providing 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, ensuring high transmission rates of the 3G network from the terminal hardware perspective, thus enjoying a more genuine 3G internet function experience.
For China Telecom's Tianyi phones, the biggest advantage lies in the existing network, ready-made 3G equipment, and nationwide network coverage." Traditional 2G-era mobile internet speeds can only ensure 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 current mobile internet speeds. Additionally, its signal will be stronger and more stable, with radiation only one-tenth of that of regular phones."
