Wi-Fi Interference Analysis
 
 

BumbleBee Wi-Fi Spectrum Analyzer

 BumbleBee is a precision calibrated spectrum analyzer that interfaces with HPs iPAQ PocketPC. The handheld receiver measures combinations of distinct wireless bands in three different models: 900 MHz, 2.400-2.500 GHz and 5.150-5.900 GHz. BumbleBee allows the user to capture, display and record each of these bands for network installation, coverage and interference analysis. The iPAQs touch screen allows field engineers to tap on points of interest in the waveform and zoom in for further analysis. Advanced spectrum analysis features include 3 waveform traces, peak hold, peak search, and user selectable power triggers. Bumble Bee allows for on-the-fly switching of bands for realtime spectral analysis of many wireless standards including RFID, VoIP, 802.11(b,a,g & Bluetooth) and cordless phones/video. Bumble Bee does the job of multiple wireless test instruments all in the palm of your hand.

FAQs
Does the BumbleBee do both 802.11b and 802.11g studies?

BumbleBee does not demodulate packets but instead scans and displays all RF energy from various popular bands including 2.4 GHz and 5 GHz frequencies.
