MINNEAPOLIS--(BUSINESS WIRE)--Sept. 25, 2000

All-Digital Platform Extends Indoor

Wireless Communications Coverage - Anywhere

ADC (Nasdaq: ADCT; www.adc.com), a leading global supplier of fiber optics, network equipment, software and integration services for broadband, multiservice networks, today announced the availability of the Digivance(TM) Indoor Coverage Solution (ICS). The Digivance ICS is an all-digital distributed antenna system (DAS) that transports RF signals digitally within or between buildings and is the initial product in ADC's Digivance(TM) family of digital RF transport solutions for managing and increasing wireless coverage and capacity.

The Digivance ICS will be unveiled in Chicago during PCIA GlobalXChange, Sept. 27-29, in ADC's booth No. 3713. ADC will also be presenting a paper on digitized wideband RF transport technology at the CDMA 2000 Technology Conference in Lisle, Ill. on Sept. 26.

The Digivance ICS is the only indoor coverage solution to offer a fully digital platform. To date, indoor coverage systems have used only analog transport platforms. By using patented technology, the Digivance ICS digitizes all signals in the full allocated bandwidth, digitally transports them over multimode fiber, and reconstructs the signals at the far end. The fully digital platform maintains the high dynamic range required for higher data rate broadband-type services, making the system even more cost effective and, in effect, future-proofing the network. Because the entire bandwidth is digitized, transportation of the signal is transparent to modulation technology, be it CDMA/TDMA/GSM/AMPS, and the signal is reconstructed at full bandwidth. In addition, balancing the system is therefore not required, saving valuable installation and set-up time.

"In our increasingly wireless world, users of mobile phones and other wireless devices expect a crisp and consistent signal regardless of their location," said Jeff Quiram, vice president and general manager for ADC's Broadband Connectivity Group, Wireless Division. "With the Digivance ICS we've employed the latest in digital RF technology, providing the infrastructure needed to ensure clear wireless communications, including the higher data-rate services such as web access over a mobile device, within or between buildings."

The Digivance ICS, by utilizing a digital platform, offers a number of advantages over current analog methods of RF extension (twisted pair, coax, fiber or microwave). With ADC's patented technology, RF signals are replicated at full dynamic range, regardless of the fiber length or the number of splits. Digital RF transport introduces no loss due to attenuation and no degradation of the quality of the signal. The higher dynamic range increases the capability for data throughput, resulting in greater versatility while maximizing indoor wireless coverage and capacity.

ADC holds six patents for its digitized RF transport technology, which has been utilized since 1993 by ADC's CityCell(R) fiber optic microcell. CityCell systems are designed for long distance RF transport.
