Radar and Cell Phones Don't Mix

The National Telecommunications and Information Administration will support the National Broadband Plan by having commercial wireless carriers share 100 MHz of spectrum in the 3550-3650 MHz band currently used for operation of Navy radar systems.

Those radars are so powerful NTIA said it will have to establish exclusion zones on the Atlantic, Pacific and Gulf coasts where cellular companies will not be able to operate.

These exclusion zones run as far inland as the Massachusetts/New York border on the Atlantic side, and Sacramento, Calif., on the West Coast, according to handy dandy maps provided by the NTIA in its spectrum reallocation plan.

Since the bulk of the population lives within a hundred miles or so of the coastline, does it make any sense go through the trouble of developing a shared spectrum plan?
