Every problem looks like a nail. I'm sorry, but I have to disagree with both Tom Evslin and Sascha Meinrath on their analysis regarding this article in the New York Times and their posts about it here (Tom's) and here ( Sascha's ). The issues that I have with Tom's take, is that most cops just want a working radio, and don't want to have to be dealing with a crashing smartphone when chasing somebody, and, to put police and life safety communications on a protocol and WLAN technology that can be so easily screwed up by somebody interfering with it, is just begging, begging for disaster. Sometimes open source or open spectrum is not the magic bullet in this case.
Also, the estimates of how much it would cost to blanket the entire City of New York and the subways are just way off base. Do you know how much the union prevailing wage is for electricians in New York? Do you know how expensive it is to use that labor in the middle of the night which is when the installations need to be done? Also, throwing a bunch of wi-fi radios in the subway is not going to work. The preferred method for signal distribution in buildings and tunnels is leaky coax and distributed antenna systems. It was true in '98, and it remains so today.
