Business Editors

ORLAND PARK, Ill.--(BUSINESS WIRE)--April 13, 2004

Centennial Puerto Rico Operations Corporation (Centennial de Puerto Rico) has signed an agreement to purchase Andrew Corporation's Geometrix(R) E911 wireless caller location systems to provide public safety agencies with accurate caller location information on cellular calls to 911.

The Andrew Geometrix system, which will be installed in the Centennial de Puerto Rico cellular network, will be compatible with Centennial's current CDMA digital technology and customer handsets, and is adaptable to future technologies that Centennial may implement.

"Centennial de Puerto Rico will not have to replace or modify its customers' handsets, because the Andrew system will provide the location capability completely in the Centennial network," said Tom Cogar, executive vice president & chief technical officer of Centennial Caribbean Operations. "Our customers will benefit immediately when the system is installed and will not have to purchase expensive new handsets in order to be located in emergency situations. One of the most important factors in Centennial's selection of the Andrew system is its ability to bring the added safety of 911 caller location to existing, as well as new customers."

Andrew's Geometrix has been selected by more carriers than any other 911 location system. Geometrix systems are in commercial service with all digital and analog wireless technologies in use in North America. In commercial service in wireless networks since October 2001, Geometrix is the only wireless location system in operation with both national and regional wireless carriers. The Geometrix system for Centennial de Puerto Rico will help the company meet Federal Communications Commission Phase II E911 wireless caller location regulations. The Geometrix system determines the position of wireless 911 callers and automatically forwards the caller location information to public safety agencies that receive 911 calls. In addition to wireless 911 caller locating, Geometrix can provide accurate location support for Location Based Services (LBS) that may be offered in the future.

"Andrew's Geometrix location system has provided emergency location support for millions of urban and rural cellular users since 2001, and now will do the same for Centennial de Puerto Rico's customers. Carriers have chosen our system above all others to provide the best emergency coverage for their customers without forcing their customers to buy new handsets. Andrew is most gratified to have been selected as Centennial de Puerto Rico's caller location system supplier," said Terry Garner, president of the Andrew Network Solutions Group.

The Geometrix location system will allow Centennial de Puerto Rico to provide locations of wireless 911 callers to emergency response centers, called Public Safety Answering Points (PSAPs), that are equipped to receive such information. Centennial customers and roamers will be able to continue using their existing handsets and current 911 calling procedures. To maintain caller privacy, Geometrix systems are designed to provide location information only when a caller initiates a 911 call.
