Cellular Modem vs. Digi Cellular Gateways
■Although the Digi Connect® WAN family products are are able to perform most functions of a cellular modem, they actually do much more. Digi Connect WAN family products are intelligent gateways with a full TCP/IP stack and embedded Real Time Operating System (RTOS) which allow remote devices and networks to be natively integrated with IP devices and applications across high-speed digital cellular networks.
■Cellular modems operate in the voice channel. This means throughput is slow and airtime is expensive. In addition, cellular modems typically require a one-to-one connection to an analog (POTS) modem connection at the opposite end of the connection. Multiple connections require modem banks to which remote sites dial in.
■Digi Connect WAN family products operate as true TCP/IP devices. They connect seamlessly to the cellular provider's IP network where only one WAN access point is required to connect thousands of devices.
