 Yellow Jacket Wifi Spectrum Analayzer
Yellowjacket B/A/G is a handheld, 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, 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 Bundpol 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), SNR (Signal-to-Noise Ratio), 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.

Frequently Asked Question

Does the YellowJacket do both 802.11b/g and 802.11a studies?
Yes, the calibrated Yellowjacket receiver can detect and demodulate both 802.11b/g, 802.11a and even 802.11h (European standard) packets. Both 2.4GHz and 5GHz spectrums.

How do I get GPS data for my 802.11 measurements?
Yellowjacket 802.11b/a/n/g model contains an internal 12-channel GPS receiver for use in outdoor drive-studies for example.

Does Yellowjacket perform site surveys?
Yes. With optional Swarm software, Yellowjacket allows mapping of any floorplan or map by overlaying Wi-Fi network coverage.
