ERF Wireless' New Canyon Lake Network Fully Operational

New Network Offers Significant Opportunities for ERF Wireless to
Expand WISP, Regional Banking and Fiber-to-the-Home Business Segments
in Central Texas 
LEAGUE CITY, Texas--(BUSINESS WIRE)--May 22, 2008
ERF Wireless (OTCBB:ERFW), a leading provider of enterprise-class
wireless and broadband products and services, announced today that the
company's new Canyon Lake WISP Network, is now fully operational and
serving the Central Texas communities of Bulverde, Sattler,
Startsville, Canyon City, Hancock, Mystic Shores, Potter's Creek and
surrounding areas. The large network, covering almost 500 square miles
around the exclusive communities surrounding Canyon Lake, utilizes
eight tower locations which are provided by the Canyon Lake Water
Service Company under a cooperative agreement in return for the
construction of a high-speed data communications network to serve the
water utility, as well as ERF Wireless commercial and residential
Dr. H. Dean Cubley, Chairman and CEO of ERF Wireless, commented,
"We believe the communities served by our Canyon Lake Network will
allow us to build and expand a significant revenue base in all three
of our strategic business segments - Wireless Internet Service
Provider (WISP) operations, regional banking networks and
fiber-to-the-home (FTTH) communities." 
The Canyon Lake area just north of San Antonio is one of the
fastest growing areas in the country. According to Bob McClung, CEO of
Bundled Wireless Services, ERF Wireless' WISP operations, "The hilly
terrain of the area makes communication services a challenge for
traditional landline providers and, until now, Canyon Lake has been
greatly underserved. However, this is a good fit for our high-capacity
wireless networks and we are pleased to be rolling our service to this
high-growth market." 
"This is a virtually untapped market for reliable, high-speed
wireless broadband," adds R. Greg Smith, CEO of Enterprise Network
Systems. "And, with the population in Comal County of thousands of
commercial businesses, over 78,000 residents and 21 regional and
community bank charters, we see an exceptional opportunity to capture
a substantial share of the market's communications business. There
even appears to be some opportunities to apply our triple-play FTTH
expertise to providing complete voice, video and data systems to
luxury gated communities in the area, as well as follow-on maintenance
and operational support."
