Mounting options for the PTP-SYNC GPS receiver
If PTP-SYNC is the selected TDD synchronization method, with a GPS receiver as the
timing reference source, then the GPS receiver must be mounted as described in this

CAUTION
Ensure that the GPS receiver module is mounted in a position where all
protection requirements can be met.

The GPS receiver for PTP-SYNC must be mounted at a location that meets the
following requirements:

.
•
It must have an un-interrupted view of the sky.
•
It must receive an adequate signal from at least four GPS satellites.
•
It must be mounted at least 1 m (3 ft), preferably 2 m (6 ft), away from other GPS
receiving equipment.
•
It must not be sited in the field of radiation of co-located radio communications
equipment and should be positioned at a distance of at least 3 m (10 ft) away.
Mount the GPS receiver on the wall of the equipment building, if there is a suitable
