Through this network set up procedure, the AvMesh
TM
Communications System can
deduce how many lights need to repeat commands or be ‘nodes’ to provide the airfield
enough coverage. ‘
After ten days of continuous operation, each light will perform a reset in which it will restart
its network set-up procedure. This allows the AvMesh
TM
Communications System to be re-
arranged without the need to power cycle each light individually.
In some cases, such as when the mesh network has been set up from different ends of the
runway, different networks can arise. Generally, networks with the lower number are better
and it is possible for some primary or reserve nodes to combine the network to which they
belong with a better network.
An example of bridging between primary nodes is shown below:
Nodes 1, 2 and 4 at one end of the runway have become primary nodes as per the network
set-up procedure and they will share the same network ID (e.g. network 132). Since nodes
9,11 and 12 are not within range of nodes 1, 2 and 4, they will also become primary nodes,
but with a different network ID (e.g. network 153). As a result, two separate networks will be
created in the same lighting system.

NOTICE:
The AvMesh
TM
Communications System is designed to be stationary to
allow the lights to run through the network setup procedure and allow
the mesh network to calibrate. If a product in the airfield needs to be
moved, it must first be turned
OFF before
being moved and can then
be turned back
ON after
being deployed in the new position to allow
the mesh network to recalibrate.
