BOCA RATON, Fla. -- CableRunner North America, LLC, a public/private business venture part owned and operated by the City of Vienna, Austria, Water and Sewer Department (Wien Kanal Abwassertechnologien GmbH - WKA) and a leading fiber optic infrastructure provider, announced today that the company's new Flexible system has been used to extend high speed services for home, business and government use in the City of Vienna, Austria. The installation was added onto Vienna's existing city network that was initiated in 1999 and that was built using the City's own CableRunner technology. The addition brings Vienna's total fiber optic infrastructure length to 400 km, housing nearly 20,000 km of fiber installs, making it one of the largest independent city networks in the world, entirely built by the City and exclusively using the City's own technology. CableRunner NA also announces Vienna's commencement of the next phase of installation, called doc.net, that will connect 30 hospitals, most of the City's emergency centers, pharmacies, administrative buildings and 911 call centers. Estimated completion of doc.net is within two years. "doc.net is a huge undertaking for Vienna, but the outcome is priceless -- saving lives and expediting emergency services," states Helmut Kadrnosk, CEO, WKA. "doc.net will be completely installed using our own CableRunner Flexible technology." Both the latest installation and doc.net utilize the Flexible system's advanced technology for backbone and access builds in both man and non-man accessible existing city infrastructures. Vienna is showcasing and promoting its city-owned network as a private, secure fiber optic infrastructure that most city, state and federal governments can install themselves and even profit from. Vienna uses portions of its network for its own private sharing of critical government information, public access to e-gov initiatives, and generating revenue by leasing to telecom companies and other providers. In its first year of operation, the City recorded new revenue of approximately $20 million. CableRunner North America LLC
