““A wireless operator without enough spectrum is like A wireless operator without enough spectrum is like a body without enough blood… If you don't have a body without enough blood… If you don't have enough blood you're going to face major medical enough blood you're going to face major medical challenges. Likewise, Wireless operators will need challenges. Likewise, Wireless operators will need more spectrum to be able to offer new services and more spectrum to be able to offer new services and applications.”applications.”

The amount of microwave spectrum is finite and has The amount of microwave spectrum is finite and has been assigned.been assigned.

It takes It takes manymany years for the FCC to go through the years for the FCC to go through the regulatory process of re-assigning spectrum (usually regulatory process of re-assigning spectrum (usually from Point-To-Point Fixed to Multipurpose, from Point-To-Point Fixed to Multipurpose, PTMP/Mobile).PTMP/Mobile).
