Two licensed frequency data modems offer long-range communications (up to 40 miles) to extend Ethernet networks into difficult-to-access locations. Design features built into the wireless Ethernet modems provide dynamic network optimization and intelligent routing for high reliability, lower latency and deterministic power management. They support 315- to 512-MHz and 928- to 960-MHz configurations, can operate in access point/client configuration, function as a network bridge/router and serve as a serial server (RS-232/-485). The modems feature node-to-node deterministic mesh network repeatability for extended range and multiple-channel spacing options to increase network scalability. These modems are optimized for throughputs of up to 25.2 Kbps.
