Did you see the new cellular router from DIGI? Digi Connect WAN 3G EV-DO Sprint Wireless router
Digi Connect WAN cellular products can be used for reliable primary wireless network connectivity to equipment at remote locations, as well as for a backup to existing landline communications. They are also ideal for use where wired networks (e.g., leased line / frame relay, ISDN, DSL) are not feasible, or where alternative network connections are required.
Digi Connect WAN products are able to provide a primary Wireless WAN connection to remotes sites containing Ethernet and / or serial devices. Applications include new construction locations, power utility substations, retail / POS sites, temporary facilities without primary wired connections, and many more.
They can also be used for backup network access.
Sprint has an MVNO plan that will be discussed on a con call coming up. If interested email me for the NDA and info.
