PAL (as the name indicates) is licensed to give interference protection from GAA users. These licenses will be auctioned in 10 MHz channels. Up to 70 MHz of PAL spectrum will be available in a given county (these 70 MHz will come from the lower 100 MHz of the CBRS band, 3550-3650 MHz). The license term is 10 years, and will be renewable. A single bidder can obtain up to 4 licenses. They are generic blocks of spectrum (i.e. you don’t bid on a specific frequency). Any frequency not being used by a PAL license is automatically considered GAA, and can be used by any qualifying GAA user. PAL licenses will be purchased at auction, which is expected to start June 25, 2020. The rules and additional information surrounding this auction are posted at the FCC website here: https://www.fcc.gov/auction/105. There are a LOT more details surrounding the PALs, and the overall auction process (including minimum bids, downpayment requirements, etc.), so please read the fact sheets, and bidding process rules to be prepared if interested.
