2.5.7 Time
Synchronization
When operating two or more collocated base stations, transmitter operations MUST be
synchronization to minimize inter-sector interference. Each BS has a synchronization
port located on the front panel to receive synchronization pulses.
2.6 Deployment
Models
The base station supports point to point (PTP) and point to multipoint (PMP) deployment
scenarios.
2.6.1 PTP
Deployment
When deployed in a PTP configuration the base station establishes a dedicated bi-
directional link to a single subscriber. The PTP deployments typically use a directional
narrow beam antenna for both ends of the link.

2.6.2 PMP
Deployment
When deployed in a PMP configuration the base station establishes bi-directional links to
more than one subscriber. PMP deployments typically use a wide beam (sector) antenna
at the base station and a narrow beam antenna at the subscriber. Service flows are used to
police service level agreements for each subscriber.
2.6.3 Non
Line-of-Sight
The RedMAX system supports line-of-sight (LOS), optical line-of-sight (OLOS), and
non line-of-sight (NLOS) operation. A clear LOS link has no obstacles within 60% of the
first Fresnel zone of the direct path. An OLOS link has obstructions within 60% of the
first Fresnel zone, but a visible path exists between the base station and subscriber. Refer
to the following illustration.
