About RadioFrame Networks

A leading supplier of targeted base-transceiver station solutions to the wireless communication industry,
RadioFrame Networks pioneered the concept of supplemental coverage and capacity in cellular RF. Today
we offer two major product lines that scale and adapt for a wide variety of mobile-network operators’
needs to optimize performance in the radio-access network (RAN). These products integrate into existing
cellular networks, extending the reach of coverage, increasing capacity and reducing operating costs and
capital expenditures. The latest RadioFrame Networks™ product line, the S-Series system, opens an
untapped market for customer-premise cellular base stations that promises improved service to small
enterprises and consumers in their homes.

RadioFrame Networks was founded in 1999 by McCaw Cellular veteran, Rob Mechaley, who saw a strong
need for indoor cellular coverage. With buildings made of concrete, steel and other materials, radio waves
have difficulty penetrating, causing cell phone users to find the nearest window to make a call.

In March 2001, employing about 30 employees, RadioFrame Networks launched its first product – a tiny
cellular site which supported both voice and data (Wi-Fi, WLAN and wireless voice). IT Departments could
install it without the need for RF engineers. In February 2003, RadioFrame Networks demonstrated a new
version of the product which converged GSM & WLAN = part basestation part wi-fi, thus allowing
expansion into the European market, while still supporting its former iDEN in-building product, used widely
by Sprint Nextel.

In 2005, RadioFrame deployed its MC-Series iDEN microcell basestation, initially used for BTS Hoteling and
in-building coverage.

Currently, RadioFrame is pioneering a solution that combines the innovative RadioBlade transceiver
functionality and all necessary service logic for IP backhaul. The RadioFrame S-Series and H-Series (future,
smaller home base station model) product lines have been developed as a flexible system capable of
adapting to carrier needs for flexibility in size, capacity and radio-interface technology. This unit is
designed to communicate directly with a BSC equipped with an IP interface. This small-capacity, all-in-one
BTS is primarily intended for those opportunities in which mobile operators are seeking fixed-line
replacement into the home or small to medium enterprise (SME). There is considerable interest in this
approach in the US, where it is estimated that 47M homes will have broadband access by 2007, and in
Europe where capabilities could even grow faster.

RadioFrame’s strategy is to forge partnerships with major equipment makers and wireless operators to
design and deploy carrier-grade solutions to meet demanding and changing customer needs. To date,
wireless operators have used our scalable, modular and future-proof platform solutions to drive their
product roadmaps and meet the ever demanding call coverage, quality and capacity needs, while enabling
new services—solutions that equate to new revenue streams.

Our innovative software-controlled radios, flexible architecture and converged platform have provided our
customers with unmatched long-term usability and ROI. We have proven experience in delivering cost-
efficient and reduced time-to-market carrier-grade wireless voice and data products. Our commitment to
adaptable design, quality manufacturing, continued process improvement and world-class customer
support has made us the leading equipment maker in the global pico-cell wireless market.
