Radio Link-Budget Calculations for ISM-RF Products

Abstract: This application note provides a customizable spreadsheet to help designers using Maxim's industrial, scientific, and medical radio-frequency (ISM-RF) products estimate the range and link margin they can achieve with a given radio design. The spreadsheet accepts inputs for frequency, transmitter and receiver performance, and radio path characteristics. It calculates the link margin and range for free space, outdoor flat earth, and indoor conditions. This spreadsheet also estimates the range and link margin of almost any radio at a carrier frequency between approximately 100MHz and 10GHz.
