Range Calculation for 300 MHz to 1000 MHz Communication Systems

Range Calculation for 300 MHz to 1000 MHz Communication Systems
(file size: 417233, 20 pages, revision B, updated: 05/2010)

This paper begins by introducing the Friis Transmission Equation and examining the terms comprising it. Then, real-world environmental factors which influence RF communication range and how they affect a "Link Budget" are investigated. Following that, some methods for optimizing RF-link range are given. Range-calculation spreadsheets, including the special case of RKE, are presented.
