the radio firmware, including data encryption, enabling or disabling
remote access channels, and password protection.
Security is not a one-step process that can be simply turned on and
forgotten. It must be practiced and enforced at multiple levels, every
day. Section
1.4 contains additional information about entraNET
security features.
License-Free
Operation
The transceivers are designed for frequency-hopping spread-spectrum
operation in the license-free 900 MHz or 2400 MHz band. They can
provide reliable long distance communications over line-of-sight signal
paths.
Multiple Services
Networks can include a mixture of equipment requiring Ethernet and
serial data interfaces on the same cell or AP. This flexibility allows the
transceiver to provide services in data networks that are on a migration
path from legacy serial or EIA-232-based hardware to faster and more
easily interfaced Ethernet systems.
Flexible
Management
Configuration, troubleshooting and other management activities are
performed using a connected PC, locally or remotely. Modes of access
include a local RS-232 console, local or remote IP access through
Ethernet, Telnet, or a Web browser, and Simple Network Management
Protocol (SNMP).
Feature Summary The MDS entraNET design makes installation and configuration an
easy task, while allowing for configuration changes in the future.
• Long-range transmission over favorable, unobstructed terrain, with
sufficient antenna heights
• Low power consumption—Sleep and Shutdown modes to enable
solar-powered operation
• Repeater configurations—A repeater scheme can be established to
extend the transmission range or to work around obstructions in a
network. This is accomplished by connecting two radios back to
back at a single site.
• Industrial-grade product—Extended temperature range for
trouble-free operation in extreme environments
• Robust radio communications—Designed to perform in
high-interference environments
• GE MDS Security Suite—Blocks common attack schemes and
prevents “rogue” hardware from gaining access to or control of a
network. Common attack events are logged and reported using
alarms.
• Fast, 106 kbps data speed—Ten times faster than 9.6 kbps radios
• Simple setup—Ethernet bridge configuration option requires
minimal setup
• Serial ports—Gateway for serial interface equipment to IP or
Ethernet networks with an embedded terminal server
