ISL067R
The ISL067R transceiver is a narrowband radio designed for license-free operation in 900MHz
ISM band.
The ISL067R has a fixed 1mW of output power for use in the USA and Canada 902MHz
– 928MHz ISM bands.
This is a full-duplex wireless data transceiver which is integrated with an ultra speed MCU
and a powerful RF chip.
A software application is offered so that users can modify the settings of the module. Its slim
size, and ultra long transmission distance makes itself the most popular selection of many
applications in different fields.
3. Theory of operation
3.1 Network Topologies
Topology refers to the shape of a network or the network’s layout. How different nodes
communicate with each other is determined by the network topology. The ISL067R support a
point-to-point and a point-to-multipoint network topology.
3.2 Point-To-Point
A point-to-point network consists of only two radios, one configured as a receiver and one
configured as a transmitter. Sometimes referred to as a wireless bridge, a point-to-point link
replaces a single communications cable.
