Smart 4G Phone Functional Features
Nov 06, 2017

In theory, 4G communication reaches the transmission rate of 100Mbps, and the 4G network is much higher than the bandwidth of the cellular system of the 3G network in the communication bandwidth. Every 4G channel will have 100MHz of spectrum, 20 times the size of the w-cdma 3G network, and more than N times faster than current cable broadband. The 4G mobile phone is the 4G mobile phone, and the mobile 4G mobile phone has the highest download speed of over 80Mbps, which is more than 10 times that of the mainstream 3G network and twice the 3G 3G network.

Scope of application

Personal application: high-speed Internet, video call, TV/video, music, online game, mobile reading, mobile phone navigation/road condition/location, etc.

Family application: family video monitoring, home multimedia phone, smart home etc.

Vehicle-mounted application: vehicle navigation, on-board TV/video/music, vehicle monitoring/security, vehicle remote maintenance, etc.

Medical application: telemedicine monitoring, mobile medical care, telemedicine, etc.

Other sectors of the industry: video conference, intelligent transportation, journalism instant communication, video customer service, etc.

Functional features

In terms of appearance, the actual appearance of the 4G mobile phone is indistinguishable from that of a common smartphone, which is characterized by high resolution, large memory, high frequency, fast processor, high definition of camera.

The 4G mobile phone is embedded with td-lte module, which is also the hardware core of China's independent research and development of 4G technology. When selecting a network, the screen signal is 4G, which means that the representative is connected to the 4G network.

As of September 2013, td-lte has the highest download speed of more than 80M BPS, more than 10 times faster than the mainstream 3G network, to download a 2g-sized movie for example, it only takes a few minutes. In addition, the user time delay is less than 0.05 seconds, and only a quarter of 3G is used. Even at the speed of hundreds of kilometers per hour, mobile 4G still offers services.

Use terminal

Mobile phones, or mobile phones, are the most common 4G terminals.

Data card: a multimode modem, with a USB port, provides a simple interface for laptops and desktops.

MIFI: MIFI is a portable wideband wireless device with a combination of modems, routers and access points. A built-in modem can connect to a wireless signal, and an internal router can share this connection between multiple users and wireless devices.

CPE: wireless router that integrates modem functions.

Number of transmission rate fast: mobile td-scdma LTE 4 g phone highest download speeds of more than 80 MBPS, reached the mainstream 3 g network speeds of more than 10 times, download movies, for example, a 700 m high-definition movie, 4 g network to download, can complete the fastest 1 minute.

The network spectrum is wider: 4G communication theoretically reaches 100Mbps, and 4G bandwidth is much higher than 3G network bandwidth. Every 4G channel will have 100 MHZ of spectrum, 20 times the 3G network.

There is an autonomous network structure: the 4G network will be a completely autonomous and adaptive network, which can automatically manage and dynamically change its structure to meet the requirements of system change and development.

Wireless network delay: user delay is less than 0.05 seconds, and only a quarter of 3G. Even at the speed of hundreds of kilometers per hour, mobile 4G still offers services.

The speed of data communication is high: the upstream of 4G network is about 10 times that of 3G, and it will improve the information capacity of surrounding environment and improve the experience performance of peripheral users. The Internet is faster and the video phone will be more fluid.

The content is broader: 3G's core application is mobile broadband Internet, video call, mobile TV, mobile phone music, mobile phone shopping, wireless search and mobile phone network, etc. The 4G will provide more high-performance mobile media content and become a personal identification device through the ID application
