Cellular router
Cellular routers are routers that provide shared Internet access by incorporating a cellular data modem and providing traditional interfaces like Ethernet and WiFi.[1]
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.
[edit] Types
There several types of devices. The compact variety is where the cellular modem and the router are the same device. These are also called "integrated" or "embedded" cellular routers. A modular device is one that connects the cellular modem to the router. These are sometimes called "slide" devices if there is a receptacle for a cellular data card. Other types allow for a USB wireless modem to plug in. Smartphones also have the ability to act as a mobile hotspot, though the mobile network operators do charge a fee for this convenience.[2]
