Cellular router
Encyclopedia
Cellular routers are routers that provide shared Internet access by incorporating a cellular data modem
and providing traditional interfaces like Ethernet
and WiFi
.
They can be deployed as a primary WAN link to a location where wired connections are not cost-effective, can also be used as a secondary or business continuity
plan should the primary cabled link fail, or can be used in moving vehicles to provide Internet access while in motion. Cellular routers range from simple SOHO network oriented devices through rugged industrial units with advanced features.
Modem
A modem is a device that modulates an analog carrier signal to encode digital information, and also demodulates such a carrier signal to decode the transmitted information. The goal is to produce a signal that can be transmitted easily and decoded to reproduce the original digital data...

Types
There are two types:- Compact: the cellular modem and the router are the same device. These are also called "integrated" or "embedded" cellular routers.
- Modular: one can connect the cellular modem to the router. These are sometimes called "slide" devices if there is a receptacle for a cellular data cardWireless modemA wireless modem is a type of modulator-demodulator which connects to a wireless network instead of using telephone or cable television lines...
