And, in a compromise designed to mollify some interest groups opposed to expanding use of white-space spectrum, Google proposed a "safe harbor" on channels 36-38 of the freed-up analog TV spectrum for exclusive use by wireless microphones, along with medical telemetry and radio astronomy devices. In effect, no white-space devices could use these channels.
This large amount of spectrum, coupled with advanced signal processing techniques made practical by the exponential growth in computing power (Moore's law), can make data rates in the gigabits-per-second available in the not too distant future. As a result, we soon could see a low cost and open infrastructure, supporting near unlimited bandwidth; improving every year as computer and radio technologies continue to evolve. This would be akin to a faster, longer range, higher data rate WiFi serviceWiFi 2.0 if you will.
We live in an era marked by two competing models of packetized communications. One in which the network provider acts as a gatekeeper by deciding which communications (in terms of content, application used, protocol used, how expensive they are) move easily across its network and onto the (authorized) handsets of users (the cell phone model).
The other in which the network provider makes available an interconnected, commodity, non-discriminatory transport service (essentially, a utility connectivity product) on which competitive communications travel that can be introduced without the knowledge or permission of the network provider and can be accessed via any handset (the Internet model).
I dont expect that either of these models will go away any time soon. However, at some point in the future, I believe that you will see fewer people carrying around pocketfuls of different kinds of wireless devices. And, you and your customers, business partners and fellow employees will soon be able to do things that are currently difficult on todays limited wireless networks.

One of the ways around the issues of security and control that make some businesses wary of cloud computing is to build a private cloud -- one that remains within the corporate firewall and is wholly controlled internally. Private clouds also increase the agility of IT an organization's IT infrastructure and make it easier to roll out new technology projects. Download this eBook to get the facts behind the private cloud and learn how your organization can get started.
