Beetle

™  is  a  handheld,  low-cost  wireless  instrument  designed  specifi-

cally for installing and maintaining 802.11a Wi-Fi networks. The calibrated 
receiver measures a wide range of RF spectrum from 5.150 GHz through 5.825 
GHz (low, middle and upper U-NII band). 

Beetle

™ measures and demodulates 

beacon packets from any 802.11a OFDM access point, bridge or client card in ad-
hoc mode and provides stats like MAC, SSID and signal strength as well as 
WEP encryption status. 

Beetle’s

 frequency range makes it ideal for wire-

less IT network technicians looking to install, verify, optimize and even 
align their 5.8 GHz antennae for point-to-point, point-to-multipoint and 
network backhaul. 

Beetle

™ is a passive, wireless tester so that users 

may study all nearby 802.11a networks “invisibly” and accurately for 
true wireless measurements and features a built-in display with keypad 
button interface for portable, PC-independent operation anywhere.
