Small cellular/WiMAX routers with integrated VPN

Low-Power Ambient Light Sensor Reduces System Cost and Simplifies System Design

Digi Connect WAN cellular/WiMAX routers provide secure high-speed wireless connectivity to remote sites and devices. These 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.

The Digi Connect WAN family is also ideal for use where wired networks are not feasible, or where alternative network connections are required. Applications include new construction locations, industrial automation, power utility substations, retail/POS sites, railroad, temporary facilities without primary wired connections, and many more.
