Domestic communications, 4G in addition to supporting modules FDD LTE/TD-LTE two LTE standards also need to be backward compatible with 2G/3G, support TD-S ** /W ** /EDGE/GP/G/ ** 1X/EVDO and other modes. In data services the maximum drop rate can reach 100Mbps and the maximum rise rate can reach 50Mbps, providing customers with high-speed Internet access and wireless data connectivity. In addition to providing high-speed data access, it also provides voice, SMS, communication and other functions, which can be widely used in notebook computers, tablet PCs, touch-screen communication devices, smart phones, video surveillance, multimedia cell phones, in-vehicle equipment and other terminal products and vertical applications. Today to introduce you to what is 4G how to use the module 4G module.
First, what is 4G module
4G module said TD-LTE and FDD-LTE and other LTE waiting network system collectively. With fast communication speed, wide network spectrum, communication flexibility, etc. 4G module refers to the hardware loaded to the specified frequency band, software support standard LTE protocol is the general term for hardware and software highly integrated modular products. The hardware integrates RF and baseband together PCB wireless receiving, transmitting, baseband signal processing functions completed on a small board. The software supports voice dialing, SMS sending and receiving, dial-up network and other functions.
Second, how to use the 4G module
4G module is usually inserted into the circuit board or patch module welded to the circuit board, and insert the appropriate module SIM card, networking through 4G cellular network. In the common transmission mode, you can use 4G to send data directly to the target server on the module G The module can simultaneously receive data from the server and send the data to the serial port side G Receive the serial port device connected to the module. Users do not need to pay special attention to the data conversion process between serial data and network packets. They only need to insert the module into the target location and set up simple connections and parameters for transmission between the serial port side and the network side.
