Overview
Warwick
Wireless products provide a quick and easy way of
connecting RS232, RS422 and RS485 serial data networks
without wires. Ideal for portable equipment or equipment
in locations where cabling is not practical.
Depending
on the frequency, RF power, height and type of antenna
and the topology of the location, ranges of up to
20Km can be achieved using a 500mW Transmitter.
Each device can be configured as a Repeater thereby
extending radio range. If a greater range is required,
either high gain Yagi Antenna or 5W, X8200HP can
be used. Both these options will generally require
consultation with the regulating Authorities.
For
a given RF power, the range decreases by one upon
the square of the frequency. If the frequency doubles
then the range is decreased by one quarter. Hence
the propagation at 2.4 GHz will be 50 times less
than at 400MHz.
