Using frequency planning
Networks will benefit from the use of fixed channel allocations if (a) the network
consists of multiple PTP links, and (b) RF interference predominantly arises from
equipment in the same network.
Frequency planning is the exercise of assigning operating channels to PTP units so as
to minimize RF interference between links. Frequency planning must consider
interference from any PTP unit to any other PTP unit in the network. Low levels of
interference normally allow for stable operation and high link capacity.
The frequency planning task is made more straightforward by use of the following
techniques:
x
Using several different channels
x
Separating units located on the same mast
x
Using high performance (directional) external antennas
For help with planning networks, refer to
