Simple link budget estimation and performance measurements of Microchip sub-GHz radio modules



Assessing the link budget with this app note (PDF) from Microchip:

This application note describes a simple link budget
analysis, measurement and techniques to evaluate the
range and performance of wireless transmission with
results, and uses developed models to estimate the
path loss for short range Microchip Sub-GHz modules
using MRF89XA and MRF49XA radios both for indoor
and outdoor environment. Hence, an attempt is made
to provide designers with an initial estimate on wireless
communication system’s performance. The
performance parameters include range, path loss,
receiver sensitivity and Bit Error Rate (BER)/Packet
Error Rate (PER) parameters which are critical in any
