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.Paragon Drive Backup
