1. Introduction
1.0 Product Overview
The IP920 is a high-performance wireless ethernet bridge and serial device
gateway. When used properly very long distance communication at very
high speeds can be accomplished. The IP920 operates in the 902 - 928 MHz
ISM band, and uses frequency-hopping spread-spectrum technology to
provide reliable wireless ethernet bridge functionality to extend LAN
network to remote locations; it also is capable of facilitating a IP/Ethernet
gateway for serial devices. The small-size and superior RF performance of
this product makes it ideal for many applications. Typical uses for this
modem include:
SCADA
Remote Telemetry
Surveillance
Traffic Control
Industrial Controls
Remote Monitoring
Fleet Management
GPS
Wireless Video
Robotics
Security
Display Signs
Railway Signaling
Many others
While a pair of IP920 modules can link two terminal devices (“point-to-
point” operation), multiple modules can be used together to create a network
of various topologies, including “point-to-multipoint” and “repeater”
operation. Multiple independent networks can operate concurrently, so it is
possible for unrelated communications to take place in the same or a nearby
area without sacrificing privacy or reliability.
