Today, with the rapid development of the Internet of Things, Internet of Things devices are understood and touched by more and more people. Jinbotong editors talk about the Internet of Things as a 4G module in communication devices.

       What is the 4G module?

       In the Internet of Things, the 4G module is an LTE network standard that supports TD-LTE and FDD-LTE, and has the characteristics of faster communication, Internet frequency bandwidth, and communication flexibility. The 4G module refers to a general term for a commodity that a hardware device is loaded into a specific frequency band, the mobile phone software is compatible with the standardized LTE protocol, and the hardware software aspect ratio is integrated and modularized. The hardware equipment integrates the radio frequency and baseband on a small PCB board for wireless network reception, transmission point, and baseband signal resolution. Mobile phone software is compatible with functions such as voice dialing, short message receiving and sending, dial-up connection to the network, etc.

     Types of 4G modules

      In the Internet of Things, 4G modules are divided into five-mode full Netcom 4G modules, seven-mode full Netcom 4G modules, mobile dual-mode 4G modules that support mobile 2G, 4G, and its mobile dual-mode 4G modules only support mobile 2G and 4G networks. The five-mode full Netcom 4G module supports Netcom communications that support GSM / TD-SCDMA / WCDMA / TD LTE / FDD LTE, and the seven-mode full Netcom adds telecommunications 2G 3G network (CDMA / EVDO). The 4G module has high-speed transmission, stable performance and other transmission characteristics. The 4G module can also carry out remote communication, real-time control, monitoring and sensing of industrial robots. The backplane of the control system has a network port or a serial port communication terminal. The 4G industrial wireless router can realize the collection and transmission of encrypted data channels of the VPN intranet. You can also use the 4G DTU serial RS485 / RS232 to directly transfer the data back to the server. The platform software collects and filters the fault information of the controller's command records.
