Before you scoff, remember that Apple has been down this path before. It first petitioned the FCC for Data-PCS frequencies for nomadic computing back in 1991. This resulted in the allocation of a juicy 20 MHz slice smack in the middle of the aforementioned PCS bands. Unfortunately for the PC industry, defeat was snatched from the jaws of victory when the entrenched telephony interests shanghaied the band in pursuit of a home for cordless PBXs. The petition proposes spectrum sharing by fixed and mobile users on a completely ad-hoc basis.
Spectrum etiquette imposes no centralized control and assumes no traffic prioritization.
Rather, it is a low level media access scheme similar to the rules we follow for private conversations at crowded cocktail parties. Beyond that, anything goes. But beware of the lobbyist-loaded coterie that frustrated Apple's plans last time. Flying under the WINForum banner, the telephony interests are angling for the same spectrum with a rival petition. Their technical approach, however, asserts the primacy of circuit-switched voice, necessitating a hierarchical architecture with choke points and centralized control.
