WinLink™ 1000 User Manual Release 1.9 B-1
Appendix B
Link Budget Calculator
Overview
The Link Budget Calculator is a utility for calculating the expected perfor-
mance 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 (fixed to 20 MHz for WinLink™ 1000)
• 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 follow-
ing data required for link budget calculations:
• Maximum Transmit power (per modulation)
• Receiver Sensitivity (per modulation) for Ethernet service and for
TDM services at various BER
• Maximum linear input power (used to calculate minimum distance)
