March 31, 2006

    GAITHERSBURG, Md., March 31 /Xinhua-PRNewswire/ -- GL
Communications Inc. today announced a "drive testing
enhancement" to their Wireless Voice Quality Testing
(VQT) Solutions ( http://www.gl.com/drivetesting.html ). 
Users of this new product can automatically analyze voice
quality of their wireless network as they drive through
their geographic region of interest. Features include: a
complete portable solution, automated call control for most
mobile phone models, support for Bluetooth(TM), and mapping
software with voice quality results and mean opinion scores
stamped with GPS time and location coordinates. 

    Rob Bichefsky, Senior Manager at GL explained,
"This tool is conveniently packaged, just plug it into
the cigarette lighter, connect to a PC Notebook using USB
connections, and start the test.  Calls are automatically
and continuously placed and voice quality statistics are
gathered and mapped."  Other quality measures include
round trip delay (RTD) measurements, noise and signal
levels, jitter, and clipping occurrences. 

    Along with automated wireless network testing, GL's VQT
