What is the speed of 3G Internet?

First, the experience of video call, after the temptation of high-speed Internet. Today, the three 3G technical standards will start completely. However, the parties on the 3G high-speed publicity despite the overwhelming, there is said that the test speed has reached 15Mbps, there are claims that the speed of 7.2Mbps, but the average consumer or "Mongolia check", 3G in the end how fast? Industry experts said that the original mobile internet users in some video downloads, 2G is impossible, it may be done in a moment. The future operator launched the music download, originally a complete song may have 5 m, have to download 20 minutes or even half an hour, now quickly, 1 minutes to solve. This should reflect the 3G in the personal life is a big "speed-up".

China Mobile (TD-SCDMA)

Download Songs 5 times times faster than the GSM era

Although TD-SCDMA (TD) in the domestic start than the other two major standards to one year earlier, but in the international, TD or Junior, belong to the rookie. At this stage, China Mobile TD has been fully upgraded HSDPA, can obtain a higher download speed, the current test results are connected to the speed of 2mbit/s, according to the local different, download speed in 80kb/s or even higher.

According to previous reports, TD downlink speed Peak theory can reach 3.6mbit/s (one said 2.8mbit/s), the peak speed can also reach 384kbit/s.

Life Trivial example: Music wireless download is a lot of mobile phone users are enthusiastic about things. In the GSM era, originally a complete song may have 4m~5m, download 20 minutes or even half an hour, and now using 3G network is very fast, a minute to download the finished.

China Telecom (CDMA EVDO)

The download speed is nearly 20 times times of CDMA 1X

Beijing Telecom has begun the commercial application of CDMA EVDO. The current experience test data shows that China Telecom CDMA2000 ev-do actual download speed 150kb/s, peak up to nearly 200kb/s. In theory, the current theory of telecom CDMA ev-do speed can reach 3.1mbit/s downlink and 1.8mbit/s uplink data service speed. The download speed is nearly 20 times times of CDMA 1X.

Life Trivial example: Beijing Telecom Deputy general manager Liu Bo said CDMA evdo speed ratio than fixed net 512K or 1M faster. Under 2mbit/s conditions, the use of high-definition camera notebook, wireless transmission, the user in any location shooting content can be transmitted through the 3G mobile transmission channel accurately.

China Unicom WCDMA

Download 100MB video A few minutes to complete

According to the media use of 3G mobile phone test data, has not yet begun to test commercial China Unicom WCDMA Network, download the average speed can reach about 322kb/s, peak unexpectedly can reach about 500kb/s. Open the Web page and play online video speed can reach 120kb/s.

Theoretically, the HSDPA of the WCDMA network can reach the upstream speed of 7.2mbit/s and 5.76mbit/s after the realization of the theory.

A small example of life: Using China Unicom's previous GSM network, downloading video can be cumbersome. However, in the download speed can reach about 322kb/s 3G conditions, you calculate a 100MB video, now it may be completed in a few minutes, is almost "instantaneous."

Read the operator's 3G speed

To know:

Read the operator's 3G speed

1.MB Relationship to MB

The relationship between the two is not clear, it is likely to be confused by the 3G speed terminology. MB is usually an abbreviation for MByte (megabytes), whereas MB is the abbreviation for Mbit. 1 bytes = 8 bits, so generally 100kb/s speed is 800kb/s.

Carriers are actually selling MB rather than MB, and if anyone claims to provide 2M of wireless broadband, the actual download rate should be 2MBIT/8, probably close to 260kb/s.

2. Sharing and Exclusive

Can you enjoy this speed by providing 2M of wireless broadband? 3G network bandwidth is still extremely limited and is fully shared. Operators said that the assumption that the allocation of mobile Internet bandwidth is 2Mbps, if the entire community (1 carrier frequency) Only one person online, then the wireless internet speed can reach 2Mbps, when 10 people, at most only 200Kbps.

3. High speed does not determine everything

People in the industry say that if you download only one program, or download a Web site file, or download a video, the speed of the 3G network provided by the operator does not determine everything and is subject to downstream restrictions.

Overall, now the domestic 3G network is still in the test or trial commercial stage, 3G network is not very mature, and the corresponding standards to achieve the theoretical value of a larger distance. Therefore, users have every reason to believe that the future mobile 3G network speed is not only more than the current ADSL fixed network, but should be to open a new high-speed network era.
