Link Budget Calculator

Overview

The Link Budget Calculator is a utility for calculating the expected performance of the RAD-
WIN 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.
User Input
You are required to enter or choose the following parameters. Depending on the product,
some of the parameters have a default value that cannot be changed.
• Band, which determines frequency and regulation
• HSU series used
• Channel Bandwidth (currently 10 and 20MHz)
• Tx Power (maximum Tx power per modulation is validated)
• Antenna Type (currently dual; cannot be changed for ODU with integrated antenna)
• Antenna Gain per site (cannot be changed for integrated antenna)
• Cable Loss per site (cannot be changed for integrated antenna)
• Fade Margin (currently 6dB)
• Rate
• Required Range and climate type
Link Budget Calculator Internal Data
For each product (or Regulation and Band) the calculator stores the following data required
for link budget calculations:
• Maximum Transmit power (per modulation)
• Receiver Sensitivity (per modulation) for Ethernet service
• Maximum linear input power (used to calculate minimum distance)
• Antenna gain and cable loss for ODU with integrated antenna
• Available Channel Bandwidths
