Time:2022-01-26 20:42:41 Popularity:706

Why 4G routers are also called LTE routers

4G router is an industrial IoT high-speed router, compatible with 4G/3.5G/3G/2.5G network, flagship-level configuration, VPN link, industrial-grade protection, wide temperature design, can easily build high-speed and stable wireless transmission network , using the public LTE network to provide users with wireless long-distance data transmission.

The 4G router adopts high-performance industrial-grade 32-bit communication processor and industrial-grade wireless module, uses embedded real-time operating system as the software support platform, and provides 1 RS232 (or RS485/RS422), Ethernet LAN, Ethernet WAN and 1 WIFI interface, can connect serial device, Ethernet device and WIFI device at the same time, realize data transparent transmission and routing function.

Industrial LTE Router

The 4G mobile Internet standard is called LTE (Long Term Evolution), so its routers are called LTE routers. Technically speaking, it is FDD-LTE (Frequency Division Duplexing) and TDD-LTE (Time Division Duplexing). The main difference between the two technologies lies in the physical layer of the air interface (such as frame structure, time division design, synchronization, etc.). The uplink and downlink of the FDD system use paired frequency bands to receive and transmit data, while the uplink and downlink of the TDD system use the same frequency band to transmit on different time slots. Compared with the FDD duplex mode, TDD has higher spectrum utilization.

Common applications of 4G LTE wireless industrial routers:

Electricity: remote automatic meter reading, real-time monitoring and alarming of voltage and current data, urban power grid, street lamp control;

Security: road construction site video surveillance, remote access control system monitoring, anti-theft device alarm;

Energy: coal mine, natural gas, oil field data collection, heating system supervision;

Transportation: monitoring and dispatching system for motor vehicles and bank cash transport vehicles, license plate capture monitoring system, vehicle violation monitoring;

Environmental protection: real-time data collection and automatic control of gas pressure regulating station, real-time monitoring and maintenance of tap water, sewage pipelines, gates, pumping stations and water plants;
