BVS Partners with EDX for Complete WiMAX Test Solution

FOR IMMEDIATE RELEASE
BVS Partners with EDX for Complete WiMAX Test Solution

METUCHEN, New Jersey. – January 14, 2009 — Berkeley Varitronics Systems and EDX Wireless partner to provide compatibility between the YellowFin™ Mobile WiMAX analyzer and EDX® SignalPro® software.

WiMAX carriers are expeditiously building out WiMAX networks coast to coast throughout the United States and the world. This requires a significant
investment in advanced test tools and software packages that will enable proper antenna placement and verification so that each WiMAX network will
have optimum performance to support the growing number of WiMAX 4G mobile devices being released. According to Scott N. Schober, President/CEO
of Berkeley Varitronics Systems, “We are excited to work with EDX Wireless who has established themselves as a global leader in wireless network
design and planning tool technology. As the WiMAX build out takes place our collective customer base require comprehensive solutions comprised of
the most advanced demodulating WiMAX receiver coupled with powerful RF planning software from EDX Wireless.”

EDX SignalPro + Network Design Add-On Module
EDX SignalPro is the principal building block of EDX’s comprehensive line of wireless network engineering tools. Appropriate for any system, including broadband wireless
WiMAX & Wi-Fi, cellular, and mobile radio, it offers all of the study types you need to design a basic wireless network, including area studies, link/point-to-point studies
and route studies. With the Network Design Add-On Module, the overall solution becomes a carrier-class design tool, complete with automatic system layout, automatic
traffic loading and automatic frequency planning – putting the Power of Smart Planning to work for you.

YellowFin™ Mobile WiMAX analyzer is the world’s first truly portable calibrated, demodulating WiMAX test receiver. This handheld unit utilizes the Samsung Q1 Ultra
Premium tablet UMPC as an interface in conjunction with Berkeley’s precision receiver technology for complete spectrum analysis as well as WiMAX packet demodulation.

The receiver sweeps the 2.0 – 5.9 GHz spectrums to within +1.5 dB accuracy. WiMAX 802.16e packet analysis includes RSSI measurements, Cell ID & Segment
information, multipath analysis and CINR (Carrier-to-Interference-plus-Noise-Ratios) on a preamble basis. The optional DF (Direction Finding) Antenna allows engineers
to pinpoint sources of WiMAX interference, rogue base stations and even nearby hackers. An internal 12-channel/satellite GPS receiver allows for geo-coded site surveys
and drive-studies using optional mapping software.
