RF Propagation, Antennas, and Regulatory Requirements
Understanding the propagation characteristics of an environment is essential in properly implementing and troubleshooting wireless networks. This chapter covers the fundamentals of RF propagation, range estimation, and range improvement techniques. Basic characteristics of antennas are also reviewed because selection of the antenna can have a considerable impact on the overall performance, range, and size of a wireless node.
