Broadband for First Responders Act of 2010 - Amends the Communications Act of 1934 to increase the electromagnetic spectrum allocation for public safety services by 10 megahertz and reduce such allocation for commercial use by the same amount.
Directs the Federal Communications Commission (FCC) to: (1) allocate the paired electromagnetic spectrum bands of 758-763 megahertz and 788-793 megahertz (referred to as D Block) for public safety broadband communications and assign such paired bands to public safety; (2) establish rules to permit a public safety broadband licensee to authorize public safety service providers to construct and operate a wireless public safety broadband network in the licensee's spectrum if such authorization would expedite public safety broadband communications; (3) require that any wireless public safety broadband network be fully interoperable, provide for user roaming, be disaster survivable, and have the appropriate level of cyber security; (4) establish regulations to authorize the shared use of the public safety broadband spectrum and network infrastructure by entities that are not defined as public safety services; (5) establish regulations to allow use of the public safety broadband spectrum by emergency response providers; and (6) develop a public safety agency statement of requirements that enables nationwide interoperability and roaming across any communications system using public safety broadband spectrum.
