902-928 MHz Frequency Hopping Spread Spectrum Transceiver
MDS...Global wireless solutions. Industrial Wireless Performance.
For almost two decades Microwave Data Systems (MDS) has been providing wireless networking solutions with applications in SCADA, telemetry, telecommunications, and online transaction markets. MDS provides licensed and unlicensed solutions, approaching 1,000,000 radios installed in 110 countries.
Introducing MDS TransNET™
Today’s SCADA/Telemetry
systems require the transport of large
amounts of data at ever-increasing
speeds. Additionally, the need for
greater packaging flexibility has
redefined the “ideal” wireless platform
in many applications. MDS is pleased to
introduce MDS TransNET™ a flexible, high
speed, compact license-free wireless
solution.
Product Overview
The MDS TransNET utilizes FHSS
(Frequency Hopping Spread Spectrum) in
the ISM Band of 902 – 928 MHz to provide
reliable long range data transportation
at up to 115.2 kbps. The TransNET
provides transparent data communications
for nearly all SCADA/Telemetry and EFM
protocols including MODBUS.
Any MDS TransNET may be configured as a
repeater extension. This allows store
and forward data operation to extend the
operating range of the network. Mulitple
repeaters may exist at any level of the
network preventing a single radio
failure from disabling the entire
network. There is no limit to the number
of repeaters which may be used. This
product is available for use in Class 1,
Division 2, Groups A, B, C & D hazardous
locations.*
Why consider an MDS TransNET™ solution?
High system
performance and data integrity!
Robust construction, digital signal
processing (DSP) technology with
self-equalization, automatic CRC/ARQ and
powerful forward error correction.
Flexibility and rapid
installation! Quick return on
investment due to plug-and-play
installation. License-free radio design
with the ability to communicate with any
asynchronous protocol without extra
software or additional programming.
Performance under the most
adverse conditions! Robust
design provides excellent performance in
the face of interference or difficult
signal paths.
Small footprint!
Exceptionally small design allows
installation inside RTU or PLC housing.
MDS network-wide diagnostics
software simplifies tasks and
reduces the cost of managing the network
infrastructure by eliminating trips to
the field. Provides a non-intrusive
means of maintaining link and radio
network performance.
Flexible interfaces!
All TransNETs come equipped with RS-232
for direct connection to most RTU/PLC’s
and RS-485 for multidrop environments.
Low Power Consumption!
Sleep mode for extremely low power
consumption requirements - typically
draws 7 mA - yet still recovers quickly
for fast access to your critical data.
MDS TransNET is the
price/performance leader;
offering flexibility and reliability for
both point-to-point and point-to-mulitpoint
requirements.
