John Keith explains why:

... Free and low-cost wireless is available - I use it all the time, at the public libraries in Copley Square and in the South End. Starbucks has monthly plans costing $29.99 and $39.99. The city has also announced plans to install wireless along its "Main Streets."

If there was a demand for wireless access, throughout the city, you can bet that a private company would have already entered the market.

That no one has, shows there is really no interest in this, beyond a few, good-intentioned, but misguided politicians. ...
