HOUSTON, and WARWICK, England, Feb. 23 /PRNewswire/ -- Crown Castle International Corp. (Nasdaq: TWRS) today announced that its subsidiary, Crown Castle UK Limited, has signed an initial agreement with BT Cellnet whereby BT Cellnet will lease space on a minimum of 1,500 Crown Castle sites throughout the United Kingdom for their 3G rollout over the next three years.

The sites selected by BT Cellnet include a significant number on existing BT exchanges, which were part of the REACH agreement signed between Crown Castle and BT Wholesale in 2000. These BT sites are located in major metropolitan areas and have direct access to BT's wholesale fiber network, providing wireless operators with a premier platform for deploying 3G services. Work on surveying and designing the first 500 of the selected sites is well underway in anticipation of this major deal.

Ted B. Miller, Jr., Chairman and CEO of Crown Castle International Corp., stated, "The BT Cellnet agreement is significant for us because it reinforces our position as a leading provider of 3G infrastructure. We look forward to building on this relationship as we continue to meet the needs of technically challenging 3G infrastructure requirements. Always mindful of the possible impact on the environment and local communities, we are building the sites with capacity to minimize the number of towers required."

Crown Castle International Corp. engineers, deploys, owns and operates technologically advanced, shared wireless infrastructure. The Company offers near-universal broadcast coverage in the United Kingdom and significant wireless communications coverage to 68 of the top 100 US markets, more than 95 percent of the UK population and more than 92 percent of the Australian population.
