Cellular router

Cellular routers (sometimes known as 3G 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, and can also be used as a secondary or business continuity plan should the primary cabled link fail.[2] Cellular routers range from simple SOHO network oriented devices through rugged industrial units with advanced features.[3]

Types

There are two types:

* Compact: the cellular modem and the router are the same device.
* Modular: one can connect the cellular modem to the router.

Data rates

Although advertised at 3.6 Mbit/s or even 7.2 Mbit/s download speeds,[4] cellular routers often suffer from low data rates due to bad reception especially in fringe areas of network coverage and densely populated areas where base station masts are obstructed by buildings, trees etc. Signal strength can be improved by connecting external antennas or amplifiers to the cellular router.
