4. Understanding RangeLAN2

RangeLAN2 radios use a radio technology called frequency
hopping spread spectrum. This means that the radio signal is
constantly moving from one frequency to another while sending
packets of data. This hopping technique allows for multiple
hopping patterns to be used in the same area and minimizes
interference.

RangeLAN2 Software Parameters

Station_Type

default=2
In order for this system to work, in each subnetwork there must
be one unit that coordinates the hops. This station is called the
Master. It might help you to think of the Master as the conduc-
tor of a frequency hopping orchestra. The Master keeps time so
all units know when to hop and what frequency to hop to.
Units classified as Stations synchronize to the Master and follow
its signal to learn what frequency in the pattern the Master is
currently using.
An acting "Master" can be configured either as a Master or
Alternate Master. Alternate Masters act either as a Master or a
Station. If an Alternate Master unit is unable to locate any other
Master within range, it acts as a Master. If a Master station is
already present, then the Alternate Master acts as a Station.
When there are multiple Alternate Masters, they coordinate
amongst themselves to determine who will become the Master.
