RADWIN 5000 HPMP User Manual Release 3.2.00 18-1Chapter 18Link Budget CalculatorOverviewThe 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 linkrange.The utility allows you to calculate the expected RSS of the link, and find the type of servicesand their effective throughput as a function of the link range and deployment conditions.User InputYou 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 typeLink Budget Calculator Internal DataFor each product (or Regulation and Band) the calculator stores the following data requiredfor 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
