1.0 Overview

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

The IP Series is a high-performance wireless ethernet bridge and
serial gateway. Alternately, a Master IP Series unit may be config-
ured 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 IP Series operates within the 902-928MHz ISM frequency 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.

1.1 Performance Features


transmission within a public, license-exempt band of the radio
spectrum
access fees or recurring charges (such as those incurred by
cellular airtime)

maximum allowable transmit power (1 Watt)

longest range

transparent, low latency link providing reliable wireless IP/
ethernet communications with constant baud rate over
distance
Key performance features of the IP Series include:
1 920-928MHz, which is license-exempt within North America, may need to be
factory-configured differently for other areas: contact Microhard Systems Inc.
