               ERF Wireless Reports First Quarter 2007
                               Results

  Progress on US-BankNet Development and Fiber-to-the-Home Agreement
               Position Company for Solid Growth in 2007

    LEAGUE CITY, Texas--(BUSINESS WIRE)--May 22, 2007--ERF Wireless
(OTCBB:ERFW), a leading provider of enterprise-class wireless and
broadband products and services, announced today that the company has
filed its Form 10-QSB with the Securities and Exchange Commission
reporting results for the first quarter ended March 31, 2007.

    Dr. H. Dean Cubley, CEO of ERF Wireless, commented, "Although the
timing of our first quarter report doesn't allow us to fully reflect
in this 10Q the significant progress we've already made this year, the
company is well-positioned to achieve solid revenue growth in 2007. We
spent the first quarter of 2007 designing and developing the Louisiana
portion of our US-BankNet system, a secure, nationally planned,
enterprise-class wireless network for the banking industry. We also
focused our efforts on expanding our product and service offerings for
financial institutions as well as upscale gated communities in order
to close significant new contracts in the near future that will
contribute to solid revenue increases for the balance of 2007."

    For the first quarter of 2007, the company reported total net
sales of $505,000, a decrease of 41% compared with $862,000 in the
first quarter of 2006. The decrease in revenue during the first
quarter of 2007 as compared to the revenue generated in the first
quarter of 2006 was primarily attributed to the timing of new
contracts and the focus of the ERF Wireless engineering and sales team
in preparing and pricing the company's new US-BankNet system in the
state of Louisiana. This preparation, now complete, was required
before the company could sign any significant new contracts with banks
operating over its US-BankNet. The company also reported Loss from
Operations of $1,128,000 for the first quarter of 2007, as compared to
a Loss from Operations of $1,321,000 for the first quarter of 2006.
The decrease in Loss from Operations was primarily attributed to an
overall decrease in operating expenses totaling $259,000 for the first
quarter of 2007 as compared to the same period a year ago. Cash used
for operating activities in the first quarter of 2007 was $534,000,
down from $799,000 in the first quarter of 2006. Primary and
fully-diluted Net Loss per share for the company's first quarters of
2007 and 2006 were ($0.05) and ($0.08), respectively.

    RECENT EVENTS

    Subsequent to the quarter ended March 31, 2007, the company:

        Golf and Beach Club of San Jose del Cabo, Mexico, to provide a
        complete Fiber-to-the-Home (FTTH) network with a voice, video
        and data system for the entire development that includes the
        operations of the private club, as well as all of the
        multi-million dollar homes in this exclusive gated community.

        Louisiana.

voice, video, and data FTTH network and a major portion of its
US-BankNet across the state of Louisiana within the next few months.

agreements during the balance of calendar 2007 and, accordingly, will
