Abstract

The SRM6200E is a frequency hopping spread spectrum Ethernet radio modem that operates in the 902 to 928 MHz frequency band. It is based on the SRM6000 radio modem that operates using the same technology. It has a 10baseT interface with a 10baseFL available. The SRM6200E can operate in transparent simplex, half duplex or full duplex modes. In order to increase the throughput efficiency, the SRM6200E learns the MAC addresses on the LAN to which it is connected and forwards only those frames destined for another LAN. Its LAN table stores up to 10000 addresses and is automatically updated. and forwarding is at the maximum theoretical rate of 15000 frames per second (wire speed). The buffer can hold 256 frames with a throughput latency of one frame. Filtering can be disabled for extender or segmented applications, allowing all traffic to flow over the WAN
