Overview of RF500 Mesh Networking

The RF500 Wireless Monitoring System uses the IEEE 802.15.4 radio transmission standard to implement a radio

mesh network.

A mesh network is comprised of the following devices:

• Gateway

• Mesh Transmitter

• Transmitter

On installation each transmitter is associated with a particular Gateway by serial number. Messages are transferred

between transmitters and the Gateway using two-way communication with acknowledgement of successful message

reception.

Transmitters which are physically close to their associated Gateway such as transmitter A in Figure 18 below will

most likely transmit directly to it. Others such as transmitter B which are further away rely on meshing transmitters to

forward messages to and from the Gateway on their behalf.

The route taken by the message can vary depending on network load and link reliability. The ability to dynamically

recongure the network is termed self-healing. In the gure below the self-healing ability is shown.
