Interference Detection Tools Analyzed

Network Computing turns in a long feature looking at tools that help troubleshoot and monitor Wi-Fi networks? health by examining the radio frequency space they operate in: The monitoring space is very hot; I?m asked all the time to be briefed on the latest product or product revision. I?ve demurred because Wi-Fi Networking News lacks an RF testing environment. The folks at Network Computing show how to examine the field. They look at a dozen products from several manufacturers, only some of which directly overlap by function.

The reviews sort products into spectrum analyzers, calibration tools (just a single entry), wireless protocol analyzers, site surveying tools, and performance and security evaluators. Spectrum analyzers look at the RF patterns and are typically intended for more sophisticated users and uses; protocol analyzers deconstruct data into known patterns to see how the airspace is being used by data devices. A spectrum tool can show if a microwave oven is disrupting your network or an errant cordless phone, while a protocol tool will let you see how 15 networks on the same channel in a small space are producing throughput degradation.
