EtherWave - WMR
1.0 Overview
The EtherWave-WMR is a high-performance wireless ethernet bridge
and serial gateway. Alternately, a Master EtherWave-WMR unit may
be configured to operate as a wireless ethernet router (and serial
gateway).
When properly configured and installed, long range communications
at very high speeds can be achieved.
The EtherWave-WMR operates within the 902-928MHz ISM fre-
quency band, employing frequency hopping spread spectrum
(FHSS) and also, for 1.1Mbps operation, digital transmission service
(DTS) technology.
They provide reliable wireless ethernet bridge functionality as well
gateway service for asynchronous data transfer between most equip-
ment types which employ an RS232, RS422, or RS485 interface.
The small size and superior performance of the EtherWave-WMR
makes it ideal for many applications. Some typical uses for this mo-
dem:

A BRIDGE separates two network
segments within the same logical
network (subnet).
A SERIAL GATEWAY allows
asynchronous serial data to enter
(as through a gate) the realm of IP
communications.
The serial data is encapsulated
within UDP or TCP packets.
A ROUTER forwards data across
internetworks (different subnets).
