Exhibit 99.1 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.
