apply power, set a few operating parameters and you are done. No

license is required for operation in the U.S.A., Canada, and many other

countries. Check the regulations in your country before placing the units

on the air.

Secure Operation

Network security is a vital issue in today's wireless world. The

MDS entraNET system provides multiple tools to help you build a net-

work that minimizes the risk of eavesdropping and unauthorized net-

work access. Some are inherent in the radio's operation, such as the use

of spread-spectrum transmission; other techniques include data encryp-

tion, enabling/disabling remote access channels, and password protec-

tion.

Remember, security is not a one-step process that can be simply turned

on and forgotten. It must be practiced and enforced at multiple levels,

24 hours-a-day and 7 days-a-week. Section 1.3 on Page 8 contains addi-

tional information about entraNET’s security features.

Robust Radio

Operation

The transceivers are designed for frequency-hopping spread-spectrum

operation in the license-free 900 MHz band. They can provide reliable

communications at distances up to 30 miles (50 km) over line-of-sight

signal paths. The units employ digital signal processing (DSP) tech-

niques for high performance operation, even in the presence of weak

signals or interference.

Multiple Services

Users with a mixture of equipment having Ethernet and serial data inter-

faces can employ a combination of both types of Remotes on the same

cell or Access Point. This flexibility allows the transceiver to provide

services in data networks that are on a migration path from legacy

serial/EIA-232-based hardware to faster and more easily interfaced

Ethernet systems.

Flexible

Management

Configuration, troubleshooting and other maintenance activities may be

performed locally or remotely. Four different modes of access are avail-

able: local RS-232 console, local or remote IP access through Telnet,

and web browser access. SNMP functionality is planned for a future

release. When available, this feature can be added to existing units by

performing a simple firmware upgrade.

At AP transceivers, the text-based interfaces (RS-232 console and

Telnet) are implemented in the form of easy-to-follow menus, and the

terminal server configuration includes a “wizard” to help you set up the

units correctly. At Remote units, a basic command line interface is used

for this function.

Transceiver

Features

The MDS entraNET 900’s design makes installation and configuration

an easy task, while allowing for changes in the future.

• Long Range—30 miles (50 km) over favorable, unobstructed

terrain, with sufficient antenna height in a point-to-multipoint

configuration
