"We view our new relationship with Teligent as an exciting opportunity to work with a company that is demonstrating real leadership in the fast-growing sector of e-business solutions," Sampson said.

Teligent offers businesses a flat monthly bill for local services with savings of up to 30 percent off the rates they pay their local phone providers.

TELIGENT SERVICE FEATURES E.MAGINESM, an interactive, Web-based business management tool that enables customers to access their billing and account information anytime they choose. Many of the benefits that Teligent offers its customers - simplicity, service, savings and speed - are the direct result of its digital SmartWave(TM) technology. ABOUT TELIGENT'S BROADBAND NETWORKS Teligent's local communications networks represent the integration of the latest advances in high-frequency microwave technology with traditional broadband wireline equipment. Together these technologies enable Teligent to increase its local network efficiency and significantly lower network costs. Teligent delivers fixed wireless services by installing small antennas on the roofs of customer buildings. When a customer makes a telephone call or accesses the Internet, the voice, data or video signals travel over the building's internal wiring to the rooftop antenna. These signals are then digitized and transmitted to a "base station" antenna on another building, usually less than three miles away. Each base station antenna gathers signals from a cluster of surrounding customer buildings, aggregates the signals and then routes them to a broadband switching center. At the switching center, ATM (Asynchronous Transfer Mode) switches and data routers distribute the traffic to other networks, such as public circuit-switched voice networks, packet-switched Internet and private data networks. ABOUT TELIGENT Based in Vienna, Virginia, Teligent, Inc. (NASDAQ: TGNT) is a global leader in broadband communications offering business customers local, long distance, high-speed data and dedicated Internet services over its digital SmartWave(TM) local networks in major markets throughout the United States.
