Gateway function of 4g lte modem router

The difference between a gateway and a router

A gateway is a computer system or device that ACTS as a transformation agent. A gateway is a translator between two systems that use different communication protocols, data formats, or languages, or even completely different architectures. Unlike Bridges that simply convey information, gateways repackage the information they receive to suit the needs of the intended system.

The differences between a gateway and a router are as follows:

The role of a router is to connect different networks and transmit information. According to usage, it can be divided into: access, enterprise level, backbone level, terabyte, multi-WAN and 3G wireless, etc.

A gateway can be a router, switch, or PC. For communication within the same network segment, it is not necessary to involve the gateway. Only when the host and non-local network segment devices communicate, it is necessary to send all the data packets to the gateway device, and then forward or route them through the gateway device.
