Link planning
Link planning
Process
The majority of the 6 to 38 GHz spectrum is licensed on a link by link basis.
Licensing regimes vary from country to country, and the planning process must
sometimes be adapted to local circumstances.
The link planning process typically consists of the following steps:
x
Identify suitable sites at the ends of the link
x
Determine the data capacity and availability required for the link
x
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.
x
Use the PTP LINKPlanner to check that a satisfactory, unobstructed, line-of-
sight path is possible between the ends.
x
Use PTP LINKPlanner to investigate the performance increase provided by
enabling ACM
x
Apply for an individual license.
x
Use the PTP LINKPlanner with the license details to identify a Bill of
Materials for the link.
x
Order equipment from Motorola.
Motorola offers a license coordination service for links in the USA. The service
includes link study, PCN, FCC application filling, Schedule-K completion and one
year license protection warranty. The FCC Microwave license coordination service
may be ordered as Motorola part number WB3659.
Site selection
The ODU and antenna should be mounted in elevated positions from the immediate
surroundings and above obstructions to provide a clear line-of-sight path to the
other end of the link. It is particularly important that no obstructions or reflecting
surfaces must be present within the near field zone in front and to the sides and
rear of the antenna.
