PTP SOLUTIONS GUIDE

The beneﬁt is that you can optimize a link before deployment by changing input data to see the effect on

performance and throughput. For example, if a link calculation indicates low throughput, then a number of

factors can be changed to see the improvement on link performance.

Operating range and data throughput is dependent on several factors, including:

• Path Length

• Antenna height on local or remote site

• Obstructions (height and distance)

• Antenna type - Integrated or Connectorized (with external antenna to provide additional system gain)

• Connectorized antenna options (Dual or single pole Flat Panels from 1’ to 2’, Parabolic from 2’ to 6’)

• Location of the link – site elevation and terrain

• Radio – select PTP 400 or PTP 600 to determine performance impact

Spatial Diversity with Connectorized Radios: The PTP Link Estimator can also be used to determine

the effect of using external antennas with the PTP 400 and PTP 600 Series Connectorized systems (each

Connectorized radio has two built in N-type connectors) with inherent spatial diversity. Spatial diversity is a

method of transmission and/or reception in which the effects of fading are minimized by the simultaneous

use of two or more physically separated antennas – ideally separated by one or more wave lengths. Here

are two conﬁguration examples of spatial diversity.
