SUBJECT: HIGH-SPEED INFRA-RED NETWORK SYSTEM
DATE: January 25, 1996
The networking company claims it has leaped the networking industry
with its latest release, an infra-red networking system that works
at distances of up to 500 meters at data transmission speeds of 125
megabits- per-second (Mbps) under normal weather conditions 230 meters under
the worst conditions.
A spokesperson for the company, told that
traditional infra-red systems have worked at between one and sixteen Mbps,
while for faster speeds, some networking companies have turned to laser
"The problem with many laser "wireless" airlinks is that anyone who looks
into the line of the laser light puts their eyesight at risk," he said. "If
you put a laser airlink system on your roof and a guy who is cleaning
windows happens to peek into the light source, the company opens itself up
to a possible lawsuit. With the new device, you avoid that problem, as
well as opening up high-speed transparent networking over long distances."
The company claims that the system can operate at distances of several
kilometers, but the specified maximum is 500 meters. "This allows the system
to work in most weather conditions, including rain, snow, and light fog. At
longer distances you tend to get fading under certain weather conditions, so
we don't recommend beyond 500 meters for this reason," .
A spokesman claims that the wireless infra-red airlink system is the
networking industry's first LED (light emitting diode)-based wireless system
to achieve ultra fast data rates, and so support ATM (asynchronous transfer
mode), Fast Ethernet (100Mbps) and FDDI (Fiber Distributed Data Interface)
Leasing fiber optic links between buildings can take
several months in some countries and situations. The system,
meanwhile, can be installed quickly and efficiently, with a complete system,
including two stations, costing from $10,000 to $15,000.
"If you just want a single network application, such as Token Ring or
Ethernet, the price is the lower reaches of this band, while if you want a
transparent link that can handle all network technologies, it's towards the
higher end of this price band," was explained.
