QTEL Americas and TekVoice Communications Form Joint Venture to Launch High Quality and Low Cost WiFi VoIP Offerings in Latin America.

DALLAS -- Access to an Estimated $8 Billion Dollar Market by 2010 with Advanced Wireless Services That Will Displace Current Mobile Operators

NewMarket Technology Inc. (OTCBB:NMKT) today announced that its affiliate, TekVoice Communications, a leader in Voice over IP (VoIP), and QTEL, a pioneer in the installation and management of secured wireless networks, have entered into a joint venture agreement to offer converged broadband voice and data services to the Enterprise, SoHo and residential markets in Latin America.

Both companies have extensive experience in Latin America. QTEL has implemented the only secure wireless network in Costa Rica, with nationwide coverage. It is currently developing additional network expansion plans across the region. TekVoice maintains Voice over IP (VoIP) services, including back office services, enterprise IP Centrex offerings, as well as domestic and international long distance services. All of these services are run on a proprietary billing and operations support platform. It maintains an extensive network of associates and distributors, as well as regional offices in Venezuela, Peru and the USA. The joint experience and in-depth knowledge of the Latin American market of both companies is an integral part of the companies' short-, mid- and long-term strategic plans.

Both companies estimate that the large market for metropolitan wireless networks based on WiFi technology are the reason for the launch of the mobile operators of the future. The convergence of a 100% IP-based broadband wireless network will allow the explosion of additional services and applications such as Logistics and Distribution, Location, Security and Surveillance, as well as expanding enterprise voice and data services into wireless private networks. The market for such services in Latin America is estimated to grow to more than $8 billion by 2010.

John Puente, President of QTEL Americas, said, "The broad experience of TekVoice in the VoIP market and its robust service and support systems are key to the development of our wireless solutions." The President of TekVoice Communications, Henryk Dabrowski, expressed, "We are very excited with this opportunity to work together in making a giant leap into the future of wireless networks. The convergence of our joint solutions of Voice over IP over QTEL's secured WiFi wireless networks makes us the first regional broadband wireless operator. We are confident that this Joint Venture will be successful in penetrating and expanding into this rapidly growing marketplace."
