HOUSTON, April 11 /PRNewswire/ -- Crown Castle International Corp. (Nasdaq: TWRS) today announced that its subsidiary, Crown Castle UK Limited, has completed its first fully outsourced wireless network, and that its customer, One 2 One, has launched in Northern Ireland. Crown Castle completed the 200-site network within 15 months of receiving the design and build contract from One 2 One, supporting its launch network targets. Crown Castle owns and operates the network, has an initial 11-year contract with One 2 One, and expects to use this infrastructure to provide services to additional 2G and 3G customers.

"Our vision for expanding the independent wireless infrastructure industry beyond tower space has reached a true milestone with the completion of our network in Northern Ireland," stated Ted B. Miller, Jr., Chairman and CEO of Crown Castle International Corp. "The future of communications infrastructure is more visible than ever before: complete design, deployment, ownership and operation of shared networks by independent infrastructure providers like Crown Castle. We pioneered this operating strategy in broadcasting after acquiring the BBC assets in 1997, and again lead the way in shared communications infrastructure for telecom."

"We chose Crown Castle to design, build and operate the network because of their significant technical expertise and successful operating track record in the United Kingdom," stated Paul Innes, Director of Network Build and Maintenance, One 2 One. "By outsourcing the network, we have avoided capital costs and reduced the need for on-site technical servicing. The agreement with Crown Castle has allowed us to make a significant entry into the Northern Ireland market while minimizing the risks."

Crown Castle engineers, deploys, owns and operates technologically advanced, shared wireless infrastructure. It 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. Pro forma for all closed and previously announced transactions, Crown Castle owns, operates, and manages over 13,000 wireless communication towers internationally.
