ERF Wireless Announces GPS-Based e911 Solution for Drilling Rig Operations That Substantially Upgrades Its Network Offerings to Oil and Gas Customers and Improves Customer Safety

June 28, 2012

LEAGUE CITY, TX--(Marketwire -06/28/12)- ERF Wireless (ERFB), providing the largest national terrestrial wireless network servicing the domestic oil and gas exploration sector, has today announced a GPS-based e911 technological advancement that further distinguishes its "best of class" wireless network servicing the oil and gas sector through its Energy Broadband subsidiary.

The majority of the Company's revenue is derived from providing terrestrial wireless broadband communications, including VoiP telephone service, to oil and gas rigs operated in remote areas of the United States. These rigs operate in areas that many times do not have marked roads, highways or streets with the only access being a pathway across open ranch land or at best a road newly scraped out of the rocks and sagebrush. In addition, even if a physical address could be established for 911 purposes, it would not appear on any current map and the drilling rig moves to a new drilling location in a matter of weeks. A major challenge has been the ability of any communications company supplying telephone service to provide 911 ("emergency services") to these "nomadic" drilling and fracing crews operating in such remote oil and gas rich regions.

ERF Wireless has successfully implemented a specialized e911 system that uses GPS coordinates, associated with the VoIP telephones being provided to the drilling site, to locate the appropriate 911 call center and to dispatch emergency personnel who are suitably GPS equipped to specific geographic locations rather than physical street addresses. Before this breakthrough, the lack of physical address precluded the remote locations from having the same 911 service that most stationary work locations in the U.S. now have. Commenting on the e911 breakthrough, ERF Wireless CEO Dr. Dean Cubley said, "As our client base and network continues to expand, we recognize that from time to time customer emergencies may arise. We are very pleased to have deployed a solution to help protect the rig-site workers. This new development is just another example of our continuing effort to improve our products and services as we gain new business on a weekly basis and expand our networks to meet the ever changing oil and gas sector needs."
