Legislators support first responders communication equipment

Sens. John McCain (R-Ariz.) and Joseph Lieberman (D-Conn.) and Reps. Jane Harman (D-Calif.) and Curt Weldon (R-Pa.) got together and wrote "A Fix for First Responders". Here's the only paragraph that isn't filler:

The federal government needs to develop a comprehensive, interoperable emergency communications plan and set equipment standards, fund the purchase of emergency and interoperable communications equipment, and provide additional radio spectrum that will allow first responders to communicate over long distances using the same radio frequencies and equipment.

Apparently there's pending legislation regarding some or all of that. Of particular interest is the spectrum part; is there the possibility that that would interfere with other uses?
