RF spectrum is divided up to give what most think is fair access to all worthy users. TV has had to give up some of its spectrum as is, i.e channels 52-83. Not a tiny chunk.
I guess you are part of "what most think."I think you would find that there are many worthy users and viable applications that cannot get spectrum.
By the way, spectrum above the 700 MHz band was reallocated to other uses a long time ago. UHF TV has been limited to channel 69 for decades. Here is what the frequencies above 700 MHz were reassigned to:
* 806-824 MHz: pocket pagers and Nextel SMR band (formerly TV channels 70-72)* 824-849 MHz: Cellular phones, A & B franchises, mobile phone (formerly TV channels 73-77) * 849-869 MHz: public safety 2-way (fire, police, ambulance - formerly TV channels 77-80) * 869-894 MHz: cellular phones, A & B franchises, base station (formerly TV channels 80-83)
THE DTV transition will reassign channels 53-69 (the 700 MHz spectrum) to other uses.
Speaking of other uses, the emergency services folks have been crying for more spectrum for several decades. A significant portion of the 700 MHz spectrum will be re-assigned to public safety applications.
Are you happy with your cellular telephone service? Does it work well inside buildings?Do you like the fact that the scarcity of spectrum for "this" application allows it to be controlled by an oligopoly that forces you to buy their approved devices and to pay through the nose for the use of a public resource?
These are the kinds of trade-offs I am talking about. These are some of the issues that Google and the White Spaces coalition are talking about.
We "could" have a free to air multichannel TV service like the U.K.We could have a broadband wireless service that is open to device attachment and advertiser supported, like the "free" TV service we once had.
What we DO HAVE is government spectrum policy and regulations that prop up monopolies and oligopolies that would not exist (in their current form) without political gerrymandering.
