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
1.4 on Page 10 contains
additional information about entraNET’s security tools.
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 up to distances of 30 miles (50 km) or more under
favorable conditions. The units employ digital signal processing (DSP)
techniques for high performance operation, 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 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 path from legacy
serial/EIA-232-based hardware to the faster and more easily interfaced
Ethernet world.
Flexible
Management
Configuration, commissioning, troubleshooting and other maintenance
activities can be done locally or remotely. Four different modes of
access are available: local RS-232 console, local or remote IP access
through Telnet, web browser access, and via SNMP. 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.
Transceiver
Features
The MDS entraNET 900’s design makes the installation and configura-
tion easy, while allowing for changes in the future.
• Long Range—30 miles (50 km) over favorable terrain, with suf-
ficient antenna height in a point-to-multipoint configuration
• Industrial-Grade Product—Extended temperature range for
trouble-free operation in extreme environments
• Robust Radio Communications—Designed to operate in
high-interference environments
• Robust Network Security—Prevents common attack schemes
and hardware from gaining access or control of network. Com-
mon attack events are logged and reported by alarms.
• Fast, 115.2 kbps data speed—Much faster than 9.6 kbps radios
• Plug-and-Play Connectivity—Ethernet bridge configuration
option requires very little setup
• Serial Ports—Gateway for serial interface based equipment to
IP/Ethernet networks with embedded terminal server
