BELLSOUTH ENTERPRISES COMPLETES FIRST E-TDMA CALL

 MOBILE, Ala., Feb. 9 /PRNewswire/ -- The first wireless telephone call using the Extended Time Division Multiple Access (E-TDMA) technology took place today when two BellSouth Enterprises (BSE) executives completed a call from an E-TDMA network built here by Hughes Network Systems (HNS) and BSE.
 E-TDMA is a potential digital operating standard developed by Hughes that could increase cellular network capacity by as much as 15 times over existing analog capabilities.
 Earle Mauldin, group president, mobile systems of BellSouth Enterprises, received the call in his Atlanta office from Eric Ensor, assistant vice president, Worldwide Wireless Strategy Group of BellSouth, who was inM?obile.
 "It's another first for BellSouth Enterprises wireless operations," said Mauldin. "We're testing E-TDMA because we've got an obligation to provide our customers with the most advanced and efficient wireless services available. This technology has the potential to improve our services, and we're going to find out if it will."
 BellSouth and Hughes began the field trial of E-TDMA last year when Hughes began installing its GMH2000(TM) Cellular Telephone System alongside BellSouth Cellular's existing mobile telecommunications system in Mobile. With the network complete, BSE is now in the process of selecting approximately 200 participants for the user phase of the trial. The participants will test system capabilities and characteristics through the use of cellular telephones that comply with both AMPS (analog) and IS-54 (digital) standards, as well as current E-TDMA (digital specifications).
 The user phase will last three-four months, with each participant being provided a modified HNS M6100 handset to use for the duration of the trial. Air time also will be free. The participants' reaction to the service and equipment will be determined through a series of telephont?erviews. Focus groups will also be used at the conclusion of the trial.
 "E-TDMA is a promising standard for increasing the capacity of wireless communications systems," said Ensor. "Given the continuing growth of cellular and the potential of new wireless services like PCS, it's critical that we continue to explore ways to improve transmission quality, coverage and other operational aspects of our wireless systems."
 "High-capacity E-TDMA provides cost-effective, increased use of cellular radio spectrum," said Pradeep Kaul, executive vice president of HNS. "This will allow cellular operators to significantly increase their network capacities to handle the anticipated cellular growth, especially as personal communications services emerge in the U.S. In addition, Hughes has already applied the E-TDMA cost/capacity advantages in the international market to service the pent-up demand for 'plain old' telephony services.
 "We are pleased to be working with BellSouth on such a far-reaching project and one that places the cellular industry one step ahead," said Kaul.
 The GMH2000 network includes a class 5 end-office digital switch, which provides the advanced, innovative and stable technology that will be required for cellular systems in the coming environment of intelligent networks and the myriad capabilities they will offer.
 E-TDMA is an extension of the current TDMA industry standard, the adopted digital standard of the Cellular Telecommunications Industry Association (CTIA). In addition to expanding capacity, E-TDMA also offers features such as frequency-hopping, improved security and enhanced channel performance and signal quality. The radio system can be remotely configured for selection of mode of operation (analog or digital), or can self-adapt to the type of traffic in the local cell. The cell site radios are expected to further reduce the costs of operations and maintenance for operators. The network itself is designed to accommodate older analog customer equipment, as well as new digital terminal equipment, allowing for the universal introduction of E-TDMA cellular service wherever AMPS-based systems are deployed. And since E-TDMA is an open architecture standard, multiple manufacturers will be able to develop equipment for it.
 The Worldwide Wireless Strategy Group studies the market and technical viability of wireless communications systems. BellSouth Cellular has operations in more than 50 markets and provides cellular service to more than 1.4 million customers. Both companies are subsidiaries of BellSouth Corporation (NYSE: BLS), a regional telecommunications holding company based in Atlanta.
 Hughes Network Systems, Inc. is a world leader in advanced digital telecommunications. The premier provider of interactive satellite networking equipment, the company also provides high-speed data transfer technology. HNS provides complete digital cellular technologies with the M6100 dual-mode cellular telephone and the GMH2000 digital cellular system. Headquartered near Washington, Hughes Network Systems is a subsidiary of Hughes Aircraft Company, a unit of GM Hughes Electronics.
