Initial Planning

Determine your hardware requirements based on the
number of RUs you will need, the distances between each
RU and the NCU. Line-of-sight limitations (i.e., physical
obstructions) should be assessed. It is advisable to have
the NCU located at the highest elevation point in the
network in order to overcome line of sight limitations. If
this is not possible, an SCU can be added to the network
to compensate.

Review your communications and networking needs and
perform a site survey. Draw a map of the network that
indicates how many units will be required, and their
locations relative to the location of the NCU.

You will need to install Subnetwork Control Units in the
network if any RU:

Will be more than 14-20 miles from the NCU
(depending on data speed).

Will not have a direct line of sight to the NCU (such
as obstruction from buildings, trees, mountainous or
hilly terrain, etc.).
