Bumblebee Wi-Fi Spectrum Analyzer

Enter Berkeley Varitronics Systems' latest spectrum-analysis offering. As surely as the worker bee tends to specific chores around its hive, the BumbleBee Wi-Fi Spectrum Analyzer tracks all radio noise interfering with your WLAN. As I found when testing the product at our Syracuse University Real-World Labs®, it performs this task with a precision that general-purpose spectrum-analysis tools like AirMagnet's Handheld Analyzer and Fluke Networks' WaveRunner can't match.

The BumbleBee handheld device graphically represents RF (radio frequency) signatures and displays numerical signal values in the bands where wireless networks and bridges play. Signal strength versus bandwidth is quantified for the 900-MHz, 2.4-GHz and 5-GHz unlicensed U.S. bands.

BumbleBee's prime directive? To track down offending radio interference without looking at the network-related details of WLAN clients, access points and other info that more general-purpose products give. This detailed but limited view will be most helpful to those who truly understand RF. General-purpose tools can indicate the presence of RF problems, but they may not adequately isolate and capture the proof of the engineering-level view provided by BumbleBee.
