Universal Wireless Communications Consortium & North American
GSM Alliance To Work Together For Multiple Third Generation Standards

ORLANDO, FLORIDA, Wednesday, September 23, 1998 - The North American GSM Alliance LLC and the Universal Wireless Communications Consortium (UWCC) announced today that the two organizations will work together to ensure that all new wireless technologies are made available to U.S. Consumers. Both organizations strongly support a United States position endorsing multiple standards for the next generation of global wireless technology currently under review by the International Telecommunications Union (ITU).

The ITU, an intergovernmental standards organization headquartered in Geneva, is coordinating a process to identify a family of global Third Generation wireless standards. Third Generation Wireless standards will provide high-speed data and Internet access, full-motion video and other sophisticated multi-media services. The U.S. Government submitted four proposals for Third Generation technology. These proposals represent the best technology for American manufacturers, operators and customers.

"Competing TDMA and GSM manufacturers and operators today come together and make it very clear: we support multiple 3G Standards," said North American GSM Alliance Chairman Don Warkentin, the President and CEO of Aerial Communications. "Efforts by other groups to artificially constrain the marketplace to one single standard are not in the best interests of the consumer."

UWCC Chairman Gregory G. Williams, Vice President - Wireless Systems SBC Communications, Inc. stated, "Currently, there are multiple technologies being deployed throughout North America and the world. This diversity of technology is good for the economy and consumers. Our cooperation with the GSM Alliance is to make sure that the interests of wireless operators, manufacturers, employees and customers are fairly represented throughout the world. "

The Chairmen of the UWCC and GSM Alliance announced they would work together on common areas of interest including 1. Free market choice of wireless technology. 2. The allocation of available spectrum independent of technology restrictions. 3. The deployment of multiple Third Generation standards. 4. The understanding that countries should not arbitrarily limit choice of standards to a single technology. 5. Agreement that second generation wireless customers and carriers be supported in the transition to 3G technology. 6. Agreement to investigate areas of potential convergence in the evolution of the technologies supported by the UWCC and the GSM Alliance.

As evidence of the cooperation between the UWCC and GSM NA, the first step in global convergence has been taken with the agreement on a common next generation of technical standards for: high speed modulation (8PSK), next generation air interface to support high speed data (200 kHz EDGE) and high speed packet data architecture (EGPRS).

Mr. Williams, stated "This effort was led by the TDMA and GSM operator community to provide a significant first step in achieving global TDMA radio interface convergence, and illustrates that a cooperative effort between even competing technology and market entities is possible when it is properly focused on customer requirements." Mr. Warkentin added "This demonstrates the commitment of the vendors and operators in the two organizations to the consumer, and bodes well for future cooperative efforts to evolve both technologies for the good of the marketplace."

The UWCC is a consortium of over 100 telecommunications carriers and vendors of wireless products and services. The consortium is dedicated to supporting TDMA, a digital wireless interface complemented by the Wireless Intelligent Network (WIN IS-41). The UWCC is a limited liability company formed in Washington State in 1996. The UWCC Board Members include: Alcatel USA, Argentina TDMA Association, AT&T Wireless Services (USA), BellSouth Cellular Corp. (USA), Cellcom (Israel), Celumovil (Colombia), Compaq Computer Corporation, Ericsson Radio Systems, HongKong Telecom CSL (China), Hughes Network Systems, Industar Digital PCS (USA), Lucent Technologies, Mobikom SDN BHD (Malaysia), Motorola Consumer Products, Movilnet (Venezuela), Nokia, Nortel, Philips Consumer Communications, Rogers Cantel (Canada), Southwestern Bell Mobile Systems (USA), Telecom New Zealand (New Zealand), VimpelCom (Russia), Sun Microsystems.

The GSM Alliance, L.L.C. is a group of U.S. and Canadian digital wireless PCS carriers, which helps provide seamless GSM wireless communications for their customers, whether at home, in more than 1,500 U.S. and Canadian cities and towns, or abroad.

GSM Alliance members include: Aerial Communications, Inc., Airadigm Communications, Inc.; BellSouth Mobility DCS; Conestoga Wireless Company; Cook Inlet PCS; DIGIPH PCS; Microcell Telecommunications Inc.; NPI Wireless; Omnipoint Communications LLC; Pacific Bell Mobile Services; Powertel, Inc.; Western Wireless Corp.; and Wireless 2000 PCS.
