Link Budget Calculator

Overview

The Link Budget Calculator is a utility for calculating the expected performance of the WinLink
1000 wireless link 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
• Channel Bandwidth
• Tx Power (maximum Tx power per modulation is validated)
• Antenna Type (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)
• Required Fade Margin
• Rate (and Adaptive check box)
• Service Type
• Required Range

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 and for TDM services at var-
ious BER
• Maximum linear input power (used to calculate minimum distance)
• Antenna gain and cable loss for ODU with integrated antenna
• Available Channel Bandwidths
