Procedures to Measure and Locate Wireless Interference
Application Notes
Introduction
Wireless communication systems often share or reuse frequency spectrum. As a result, wireless systems are prone to interference. Interference can have many causes, however here we will explore interference that is created by wireless systems operating properly or improperly. In wireless communication systems, interference is commonly created by: one signal infringing on another, operating system components such as transmitters operating improperly, or the communication system itself triggering interference in sensitive equipment. Since all wireless communication systems are vulnerable to the effects of interference, the ability to quickly and accurately measure frequency spectrum in and around the wireless system is an essential step in restoring system integrity. This application note looks at the process and techniques for measuring and locating wireless interference using a handheld, portable spectrum analyzer.
