Computerworld reports that New York City will build a wireless network to supports 10,000s of public-safety users at speeds of up 70 mph: Bids are expected next month. They'll start with a three-month pilot project to test with multiple bidders, and then award a five-year contract with the potential for two five-year renewals.
The bid's spec apparently calls for two Mbps access and simultaneous streaming for 1,000s of users. The first phase would support about 5,000 fire, police, and emergency medical personnel.
The full cost could be $500 million to $1 billion, but the city won't confirm it. Mesh architecture is practically a necessity, the article quotes experts as saying. Tropos says they could deploy such a network with 600 of their access points in the 2.4 GHz band. More would be needed to use the 4.9 GHz public-safety band. Lucent suggests that EvDo running at 2.4 Mbps in the 1.9 GHz band would be an option as well.
