Settings
Mode
Three different roles can be assigned to a node: master, alternate master, or slave. Each
role governs how links are established. Links are defined as either upstream or
downstream.
Master: The master is the root node that provides the upstream connection to the
ground network that the other nodes want to reach. The master will only create
downstream local mesh links to alternate master or slave nodes.
Slave: Slave nodes can only establish upstream links with master or alternate master
nodes. Slave nodes cannot establish downstream links with other nodes.
Alternate Master: An alternate master node must first establish an upstream link
with a master or alternate master node before it can establish downstream
connections with an alternate master or slave node.
Mesh ID
Unique number that identifies a series of nodes that can connect together to form a local
mesh network.
Allowed downtime
The maximum time (in seconds) that a link can remain idle before the link actually gets
deleted. When a slave (or alternate master) looses its link to its master, the discovery
phase is re-initiated.
Minimum SNR
(Alternate master or slave nodes)
This node will only connect with other nodes whose SNR is above this setting (in dB).
SNR cost per hop
(Alternate master or slave nodes)
This value is an estimate of the cost of a hop in terms of SNR. It indicates how much SNR
a node is willing to sacrifice to connect to node one hop closer to the root node, because
each hop has an impact on performance, especially when using a single radio.
Initial discovery time
(Alternate master or slave nodes)
Amount of time that will be taken to discover the best available master node. The goal of
this setting is to delay discovery until all the nodes in the surrounding area have had time
to startup, making the identification of the best master more accurate. If this period is too
short, a slave may connect to the first master it finds, not necessarily the best.
Security
Enable this option to secure data transmitted on the wireless link. The APs on both sides of
the wireless link must be configured with the same security options.
