, speed is the key to win, speed will be directly related to the user's choice, a look at the three major Internet card speed.
This column more highlights: http://www.bianceng.cn/Network/wxwl/
Mobile TD-SCDMA network card, the highest theoretical speed of 384Kbps, with the 2.5G Era Edge wireless internet card speed the same as 3G card, this speed users will certainly not accept. Fortunately mobile also saw this problem, in the TD-SCDMA two construction introduced HSDPA technology, the highest

(Here, I'm a little confused by what the original author meant, since you have modified JS or CSS, then the version of HTML introduced in these files will inevitably change, that is, HTML is also followed by changes, if you do not publish new H
3G mobile phone is commonly referred to as the third generation (the third Generation) mobile phone. With the development of technology and economy, the current mobile phone varieties and models are also many people dizzying, from the first generation analog mobile phones to the second generation of GSM, TDMA and other digital mobile phones, and then to the current third generation of mobile phones, mobile phones have become a set of voice communication and multimedia communications combined, an

Finally, a brief introduction to the use of 3G network for wireless internet access.
3G Internet is following the GSM, GPRS, edge of the new technology, one of the three major domestic operators China Mobile is the independent property rights of TD-SCDMA, speed up to 2.8M; China Telecom uses CDMA 2000 technology, now erected EV
supports synchronous dynamic random memory (SDRAM) and NAND flash RAM.3, multi-mode mobile terminal baseband chip is inevitable, that is, eventually on a baseband chip to support all mobile network and wireless network format, including 2G, 3G, 4G and WiFi, etc., multi-mode mobile terminal can achieve a global range of mobile networks and wireless network between the seamless roaming. such as 3G baseband chip most support GSM/GPRS and WCDMA two modes, Qualcomm Company launched has CDMA2000, WCD
(Flash RAM). Extended memory generally supports synchronous dynamic random memory (SDRAM) and NAND flash RAM.3, multi-mode mobile terminal baseband chip become a must. Finally, on a baseband chip to support the entire mobile network and wireless network format. Includes 2G, 3G, 4G, WiFi, and more. Multi-mode mobile terminals enable seamless roaming between multiple mobile networks and wireless networks around the world.For example, 3G baseband chips support GSM/GPRS and WCDMA two modes.
