Yellowjacket® B/A/G is a wireless test receiver system that demodulates, sweeps, analyzes, and optimizes all popular 802.11 Wi-Fi network standards including 802.11b/g (2.4 GHz), 802.11n, 802.11h and even 802.11a (5 GHz). The calibrated receiver is a passive measurement device that is network independent so it remains "invisible" to any 802.11 Wi-Fi network. Yellowjacket® B/A/G is also a powerful spectrum analyzer that measures RF energy (2.0-4.0 & 4.9-5.9 GHz) allowing not only detailed interference analysis but the ability to see the "whole picture" of your 2.4 and 5 GHz network WISP or hotspot. When equipped with a BVS DF (Direction Finding) antenna, Yellowjacket® B/A/G locates and pinpoints rogue APs and STAs and even detects interference from sources such as microwave ovens and cordless phones. Powerful packet analysis features such as Multipath (Ec/Io), Delay Spread, Channel Frequency Response (CFR), SSID and Received Signal Strength Indicator (RSSI) give Yellowjacket® B/A/G the distinction of being the only true handheld RF spectrum protocol analysis and direction finding tool accurate to within 1 dB. Yellowjacket® B/A/G functions as a complete WLAN analysis system offering both measurements made through packet demodulation and spectrum analysis in a rugged, handheld package.
