Yellowjacket® is a calibrated wireless receiver module that interfaces with HP’s iPAQ® PocketPC® in sweeping, analyzing and optimizing 2.4 GHz Wi-Fi Networks. The receiver measures all 14 OFDM/DSSS network channels which operate on the IEEE 802.11b/g standard allowing the user to determine the AP’s MAC, SSID and RSSI signal levels for all access points on or off any 802.11b/g WISP or Hotspot. The Yellowjacket® system uses a custom receiver, custom software and interfaces with an iPAQ giving Yellowjacket® the distinction of being the only true RF spectrum protocol analysis and direction finding tool accurate to within 1 dB. Berkeley’s calibrated receiver sweeps and measures all RF energy in the 2.4 GHz range as well as on each of the 14 OFDM/DSSS channels for detailed network inspection of any nearby 802.11b/g APs or STAs. Yellowjacket® is a passive, network independent device with the ability to see the “whole picture” as well as pinpointing channel interference and hackers that plague so many 802.11b/g WISPs and Hotspots. Yellowjacket® can contain an optional 12-channel GPS receiver for realtime GPS data so that every 802.11b/g measurement is time/date/location stamped for post analysis using spreadsheets or Berkeley's own Dolphin™ mapping coverage analysis software. · 2.4 GHz Spectrum Analysis · SSID Detection · Direction Finding (for use with optional DF Antenna) · W.I.S.P.
