The FCC put forward a proposal for rule changes on Wednesday that could significantly speed up better coverage for CDMA carriers in the US. It would use the same strategy that was used for the 700MHz and 1,700MHz (AWS) auctions, where licenses would be handed out based on auctions for regions. The earlier approach relied on analog signal propagation at cell sites and was now more of a hindrance than a help in areas where coverage had long since been filled out, the agency said.
