1.1 PRODUCT DESCRIPTION
The MDS
i
NET 900 unit is designed to provide an easy-to-install wire-
less local area network (LAN) service with plug-and-play hardware,
with Ethernet, and serial data interface options supporting up to
512 kbps.

Rugged Packaging
The
i
NET 900 is housed in a compact and rugged cast-aluminum case
that needs only to be protected from direct exposure to the weather. It
contains a single printed circuit board with all necessary components for
radio operation and data communications. The only user-serviceable
component within the case is the fuse on the DC power input.
Simple Installation
The basic installation typically utilizes an omni-directional antenna at
the Access Point location and a directional antenna at each Remote unit.
The antenna is a vital link in the system and must be chosen and installed
correctly. Consult the
PLANNING AN iNET RADIO NETWORK
on
Page 97 about choosing a site and antenna selection.
For basic services, just hook up an antenna, connect your Ethernet LAN
to the

NET 900’s
LAN
port, apply primary power, check and set a few
operating parameters as necessary and you are done. No license is
required for operation in the U.S.A., Canada, and many other countries.
Robust Radio
Operation
The
i
NET 900’s radio transceiver is designed for frequency-hopping
spread-spectrum operation in the license-free 900 MHz band. The
MDS
i
NET 900 can provide reliable communications up to distances of
30 miles (50 km) under favorable conditions, even in the presence of
weak signals or interference.
Flexible Services
Users with a mixture of equipment having Ethernet and serial data inter-
faces can choose to use one or two of the user-configurable serial ports
through the use of a Remote Dual Gateway. This flexibility allows the
i
NET unit to provide services in data networks that are on a path from
legacy serial/EIA-232-based hardware to the faster and more easily
interfaced Ethernet world.
Transceiver
Features
The MDS
i
NET 900’s design makes the installation and configuration
easy, while allowing for changes in the future.
