EDX Wireless Expands Its Carrier-Class Ecosystem To Include WirelessLogix As The First WiMAX Drive Test Equipment Vendor

EUGENE, Ore., December 13, 2007 – EDX Wireless has added WirelessLogix to its
Vendor Partner Program as the first drive test manufacturer to join the EDX ecosystem.
Under the terms of the partner agreement, the data collected by WirelessLogix’ XCAL-X
tool is able to be used in EDX SignalPro® directly, without any data conversion processes.

The smooth integration between the network planning tool and the data derived by the
network drive test tool brings increased value to the engineering process. Direct access
to this data saves time for RF engineers and makes the process more consistent and

As part of the network planning process, EDX SignalPro uses the drive test data to
provide a comparison of predicted versus measured coverage, as well as to automatically
tune propagation models used to predict network performance. Further, the data can be
used to determine the signal loss caused by clutter, such as trees, which can be unique to
each market.

“EDX’s WiMAX customers are pleased to see this integration with WirelessLogix,” said
Ted Hicks, Vice President of Product Management for EDX Wireless. “WirelessLogix
has the first complete real-time WiMAX data collection tool and providing this
integration is a natural addition to the ecosystem we’re building to support our growing
customer base.”

“WirelessLogix is quite excited to expand it’s partnership with EDX in support of the
WiMAX ecosystem,” said Larry Smith, WirelessLogix COO. “Our customers are calling
for an integrated solution that supports both WiMAX network design and optimization,
and the partnership with EDX satisfies this request.”

Current versions of EDX SignalPro and its modules have the integrated connectivity to
WirelessLogix data, making the combined solution immediately available. Pricing is
dependent on final configurations of each product.
