Andrew Debuts EOCell RF Over Fiber Solutions.Business Editors ORLAND PARK, Ill.--(BUSINESS WIRE)--Nov. 13, 2002 Andrew Corporation's (NASDAQ NASDAQ in full National Association of Securities Dealers Automated Quotations U.S. market for over-the-counter securities. Established in 1971 by the National Association of Securities Dealers (NASD), NASDAQ is an automated quotation system that reports on :ANDW) new EOCell(TM) RF Over Fiber solutions provide efficient transport of wideband RF signals over optical fiber. Applications for EOCell include wireless distribution networks needed for "base station hotels," airports, campuses, road tunnels, and metro systems. Essentially, an EOCell system will convert RF signals to fiber optic signals for long distance transmission and then convert them back to RF signals at a remote location. Because a typical EOCell system requires only one base station site to support multiple cells, its benefits include the reduction of recurring back-haul costs, and simplified zoning approvals. A system can also be used in multi-provider deployments for even greater cost savings. "We are extremely excited about EOCell's potential for cost-effective base station hotelling See hoteling. for both single carrier and shared networks," said Matt Melester, Director of In-Building and Wireless Solutions, Andrew Corporation. "EOCell's advantage is that it carries much, much more information over far, far longer distances." A typical EOCell system might comprise a master site Fiber Optic Distribution Unit that accommodates up to eight independent long haul fiber transceiver links, two active signal combiners, redundant power supplies, and an alarm/communications processor card that relays alarm data back to an operations center. Each transceiver link provides an FM-modulated subcarrier A secondary telecommunications channel that resides within the main channel (a carrier within a carrier). A type of multiplexing, the subcarrier is a modulated carrier signal at a lower frequency that is combined with the main carrier signal running at a higher frequency. capable of carrying voice or RS-232C (3-wire) data for relaying control and status signals to and from remote transceiver nodes. EOCell fiber transceivers are available as stand-alone modules. EOCell fiber transceivers can also be used to distribute Cellular and PCS (1) (Personal Communications Services) Refers to wireless services that emerged after the U.S. government auctioned commercial licenses in 1994 and 1995. This radio spectrum in the 1. signals to the Andrew InCell(TM) in-building fiber optic distributed antenna system As defined by PCIA - the Wireless Infrastructure Association, and it's DAS Forum, A Distributed Antenna System ,or DAS, is a network of spatially separated antenna nodes connected to a common source via a transport medium that provides wireless service within a geographic area or and to Andrew high power outdoor Cellular and PCS repeaters. The broadband operation of the EOCell fiber transceiver (88-2500 MHz (MegaHertZ) One million cycles per second. It is used to measure the transmission speed of electronic devices, including channels, buses and the computer's internal clock. A one-megahertz clock (1 MHz) means some number of bits (16, 32, 64, etc. ) enables the distribution of a variety of other signals for FM radio, CATV (Community Antenna TV) The original name for cable TV. It used a single antenna at the highest location in the community in order to deliver a quality signal to homes in areas with hilly terrain or other interference. , trunked radio, satellite, and ISM See ISM band. applications. EOCell systems designed and installed by Andrew Corporation's Distributed Communication Systems Division, are currently being used in subway wireless access systems in Atlanta, Philadelphia, and Hong Kong.
