Smart 4G Phone Choose The Reason
Aug 22, 2017

4G communication theory to achieve 100Mbps transfer rate, 4G network bandwidth in the 3G network than the cellular system bandwidth much higher. Each 4G channel will occupy 100MHz spectrum, equivalent to 20 times the W-CDMA 3G network, the network transmission speed is much faster than the current cable broadband N times. [1] 4G mobile phone is to support 4G network transmission mobile phone, mobile 4G mobile phone maximum download speed of more than 80Mbps, to mainstream 3G network speed of 10 times, is Unicom 3G 2 times.

Features

From the appearance point of view, 4G mobile phone real machine appearance and common smart phone is no different, their main feature is the high resolution, memory, high frequency, the processor running fast, camera HD.

4G mobile phones are embedded in the TD-LTE module, which is China's independent research and development of 4G hardware core technology. When selecting a network, the screen signal shows 4G 'that is connected to the connected 4G network.

As of September 2013, TD-LTE mobile phone maximum download speed of more than 80M bps, to mainstream 3G network speed of 10 times to download a 2G size of the film as an example, only a few minutes. In addition, the use of the user delay is less than 0.05 seconds, only 3G 1/4. Even in the hundreds of kilometers per hour high-speed running, mobile 4G can still provide services.

Choose the reason

Compatibility is better: 4G compatible with existing 2G, 3G, 4G network, "multi-mode multi-frequency" has become a standard 4G mobile phone.

Transmission speed: mobile TD-LTE 4G mobile phone maximum download speed of more than 80Mbps, to mainstream 3G network speed of 10 times, to download movies, for example, a 700M high-definition movies, with 4G network download, the fastest 1 Minutes can be completed.

Broad spectrum of the network: 4G communication theory to achieve 100Mbps transmission, 4G network bandwidth than 3G network bandwidth much higher. Each 4G channel will occupy 100MHz spectrum, equivalent to 20 times the 3G network.

Autonomous network structure: 4G network will be a fully autonomous, adaptive network, can be automatically managed to dynamically change their structure to meet the system changes and development requirements.

Wireless network delay reduced: the use of the user delay is less than 0.05 seconds, only 3G 1/4. Even in the hundreds of kilometers per hour high-speed running, mobile 4G can still provide services.

Data communication speed: 4G network uplink and downlink speed is about 10 times the 3G, and will improve the surrounding environment, information capacity, improve the performance of peripheral users experience. Internet speed is faster, video phone will be more smooth.

Broadband content: 3G core applications for mobile broadband Internet access, video calls, mobile TV, mobile music, mobile shopping, wireless search and mobile online games and so on streaming applications; 4G will provide more high-performance mobile media content, and through ID application becomes a personal identification device

Main services: 4G packages, sets of traffic than 3G packages increased significantly. To 3G basic package comparison with the monthly fee similar to the 4G package file, set the voice to improve the set of data flow also increased a lot.

4G extensive operation will enable domestic and foreign telecommunications equipment manufacturers to provide 4G mobile phone manufacturers, as well as the domestic Internet industry benefited. Yang Peifang, chairman of the China Society for Information Economics, said that there are 1.3 billion people in China, the number of mobile phones has 1.1 billion, it is possible to reach 1.2 billion, 4G development space is huge. Experiments show that technology is no longer a problem.

The use of 4G mobile phone can not only call, Internet, but also have the entertainment and payment and other new games, users can easily and safely brush mobile phone consumption
