The Federal Communications Commission’s new auction application filing and bidding system known as the Integrated Spectrum Auction System ("ISAS"), which comprises a Form 175 electronic filing component and a bidding component, has replaced the previous FCC Form 175 system and the FCC Automated Auction System.

Compared with the previous systems, ISAS includes FCC Form 175 application enhancements — such as automated checking of data accuracy, improved application search functionality, and integration with FCC Form 602 — as well as bidding system changes for easier navigation, customizable results, and enhanced bidding features. The new bidding system allows for multiple types of auctions (e.g., simultaneous multiple round auctions or simultaneous multiple round auctions with package bidding).
