Link planning
When planning the link, follow the high level process described in this section. Take
account of factors such as site selection, wind loading, cable length and power supply. Use
PTP LINKPlanner as a tool to plan the link.
Process
The majority of the 6 to 38 GHz spectrum is licensed on a link by link basis. Adapt the
planning process to suit the licensing regime that is in force in the country of operation.
To plan the link, follow this high-level process:
1
Identify suitable sites at the ends of the link.
2
Determine the data capacity and availability required for the link.
3
Select an RF band, taking into account the range of link, the capacity required, the
availability required, the licensing policy for bands in the region or country, and
likely availability of individual licenses in that band.
4
Decide whether or not Spatial Diversity is required. Regulations may mandate, or at
least recommend Spatial Diversity for certain lengths of link. Use PTP LINKPlanner
to estimate the performance increase provided by enabling Spatial Diversity.
5
Decide whether or not to deploy 1+1 Hot Standby. This may be required for very
critical links where outages due to equipment failure cannot be tolerated. If Spatial
Diversity is selected, 1+1 Hot Standby automatically becomes available.
6
Decide whether to install the Radio Frequency Units on the mast (ODU) or indoors
(IRFU). Use the same option at both ends of the link.
7
Use PTP LINKPlanner to check that a satisfactory, unobstructed, line-of-sight path
is possible between the ends.
8
Use PTP LINKPlanner to estimate the performance increase provided by enabling
ACM.
9
Apply for an individual license.
1 0
Use PTP LINKPlanner with the license details to identify a Bill of Materials for the
link.

Order equipment from Cambium.
