Have you tried to use a mobile phone as a "cat?

"In addition to video calls, what is fun with 3G mobile phones? It is said that it is capable of high-speed Internet access and Internet access in the 2G age. What's so strange ?" Recently, with China Unicom and China Telecom's 3G business coming soon, reporters are facing this issue more and more. Indeed, in the hearts of many citizens, the biggest selling point of 3G mobile phones is video calls, followed by mobile Internet access. However, this function is not a new function strictly, 2g/2.75g networks can also access the internet.

Is this really all about the facts? Are there any secrets we have not tapped into for high-speed Internet access through 3G mobile phones? Take TD-SCDMA as an example, in addition to direct mobile Internet access and TD-SCDMA data card Internet, TD-SCDMA mobile phone can also be "modem", connected to the PC on the Internet.

3G Internet access is not far away

3G technology combines the Internet, fully considering the needs of multimedia services, through the use of broadband RF channels, increase the speed of the code, and so on to achieve high-speed transmission. Therefore, in the 3G era, mobile Internet surfing has become a boom. The theoretical rate of TD-SCMDA is 384 K/s, which is higher than the existing data transmission modes in the 2G era. Through the reporter's mobile phone Internet experience, under normal conditions, the video programs and cell phone TV on the network are relatively smooth, and the channel switching speed is relatively fast, about 3 ~ The channel switching is completed in about 5 seconds. It is reported that the download speed of the TD-SCDMA is quite fast, although it failed to reach its theoretical rate of 384 K/S, but the download of the two video clips, the peak rate of more than 200 K/s. A 29-second video is downloaded in about 5 seconds. Of course, the above is achieved when the TD signal coverage is good.

The functionality of TD-SCDMA Internet is nothing more than that, and there is an app you may ignore-wireless Internet access via a computer. Using a TD-SCDMA data card or using a TD-SCDMA phone as a modem can all be connected to your PC. According to some testers, the network signal coverage is good, the computer connection TD-SCDMA speed is still quite fast, higher than the existing GSM and CDMA 1X wireless access.

Upgrade HSDPA for faster transmission

Generally, 3G is transmitted indoors (3 km/h), outdoors (30 km/h), and high-speed mobile environments (FDD: 500 km/h, TDD: 120 km/h ), 3G mobile phones can process images, music, videos, and other multimedia information at a rate of 2 Mbps, 384 kbps, and kbps respectively, supports applications such as video calls, mobile TVs, and high-speed Internet access.

Upgrading to Gbps makes the Internet feel "fast. HSDPA, also known as the 3.5G Technology for High-Speed Downlink access, is an upgraded version of the global construction technology. It can be used without changing the current 3G network structure, increase the peak rate of the downstream link to a single carrier of 2 to 8 m.

The maximum downstream speed of 3G mobile phones using HSDPA technology can reach 2.8 Mbits, which is nearly seven times faster than that of normal mobile phones. When two identical mobile phones are playing streaming media on the HSDPA network and edge network, we can see that playing in the HSDPA status is very smooth and has almost no latency, while in the edge state, the screen is very cartoon, And the mosaic and screen delay is serious.

Three-way TD-SCDMA surfing

Direct Internet access via mobile phone

Directly log on to WAP or HTTP web browsing through a TD-SCDMA phone. To avoid high Internet traffic fees, you are advised to select a package containing Internet traffic fees. Currently, the packages launched by China Mobile include 20 RMB 150 m, 50 RMB 500 m, 100 RMB 2g, and 200 RMB 5g. The traffic fee exceeding the package is 0.01 RMB/kb, and the monthly ceiling is 1000 RMB (for details, consult your local company and refer to the published price ).

TD-SCDMA data card connected to computer internet

Similar to the 2G era of GSM/CDMA 1X Internet access, coupled with a TD-SCDMA dedicated data card, can be connected to the computer, in the computer "network connection" dial settings, you can use the data card to connect to the TD network to surf the Internet.

When modem is connected to a computer

When the mobile phone "cat", in fact, not new, simply said, is the first installation of TD-SCDMA mobile phone itself configured in the disc mobile phone Internet software to the computer, connect the phone to the computer through a USB cable; reference manual, set the network connection in the TD-SCDMA phone to "phone modem Internet ", then, set up the mobile Internet access software installed on your computer, and click the software to dial the internet. In addition, there are pre-stored phone bills that can be purchased for 1 yuan in the Guangzhou Mobile Business Hall, among which there are mobile phones that can be used as "Cats", such as "coolai 6168" and "da t2222 ".
