Link Budget Calculator
Overview
The Link Budget Calculator is a utility for calculating the expected performance of the
RADWIN 5000 HPMP wireless link within a sector and the possible configurations for a
specific link range.
The utility allows you to calculate the expected RSS of the link, and find the type of services
and their effective throughput as a function of the link range and deployment conditions.
