Smart 4G Phone The Scope Of Application
Sep 12, 2017

4G communication theory to achieve 100Mbps transfer rate, 4G network bandwidth in the communication than the 3G network 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.

The scope of application

Personal applications: high-speed Internet access, video calls, TV / video, music, online games, mobile phone reading, mobile navigation / traffic / positioning and so on.

Home applications: home video surveillance, home multimedia phone, smart home and so on.

Car applications: vehicle navigation, car TV / video / music, vehicle monitoring / security, vehicle remote maintenance.

Medical applications: telemedicine, mobile medical care, telemedicine, etc.

Industry other categories: video conferencing, intelligent transportation, news industry that is, that is, video customer service.

Features

From the appearance point of view, 4G 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 technology hardware core. When the network is selected, 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.

Use the terminal

Mobile phones (ie mobile phones) will be the most popular 4G terminal.

Data Card: A multimode modem that uses a USB interface that provides a simple interface to the laptop and desktop computer.

MIFI: MiFi is a portable broadband wireless device, set the modem, router and access point three functions in one. The built-in modem can access a wireless signal, which can share this connection between multiple users and wireless devices.

CPE: Wireless router with integrated modem function.

Choose the reason

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

The number of 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 HD movie, 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 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 media applications; 4G will provide more high-performance mobile media content, and through ID application becomes a personal identification device
