Point to-point links and base stations must be registered in the pursuant to procedures to be established by the Wireless Telecommunications Bureau prior to operation. Prior to filing a site registration, a licensee must successfully coordinate with the relevant co-channel Federal and non-Federal licensees. Site registrations will be processed in order of receipt unless a later filed registrant provides evidence that it completed coordination prior to the other registrant.

(a) Federal military operations have priority in the 37-37.2 GHz band (priority access). Non-Federal licensees can register and deploy sites in the 37-37.2 GHz band, but must modify or cease operations in the future if those operations conflict with later-deployed military operations. A licensee's operations in this band will not be protected from harmful interference from subsequent military deployments.

(b) If a licensee is notified that its operations conflict with incoming military operations and priority access has been invoked, the licensee must work with the Federal military operator in good faith to either modify service to be consistent so it does not conflict with the military operations or cease operations if coexistence is not possible.

(a) After giving licensees an opportunity to obtain nationwide non-exclusive licenses, the Wireless Telecommunications Bureau shall, by public notice, establish procedures for licensees to file an initial set of site registrations (the initial site registration round).

(b) In the initial site registration round, licensees may register a maximum of two 100-megahertz channels at any given site.

(c) Sites registered in the initial registration round must be constructed and providing service within 120 days of the site registration being granted.

(d) If multiple site registrations with overlapping Phase One contours are filed during the initial site registration round, the Wireless Telecommunications Bureau will grant the earlier filed registration (based on the Universal Licensing System's time stamp). Both licensees shall then engage in Phase Two coordination with respect to the later-filed registration. The licensee with the later-filed registration may amend its application to facilitate coexistence with the other licensee so long as the amendment does not conflict with any other site registration filed during the initial window or with any existing or proposed Federal operations. If Phase Two coordination is successful, the later-filed registration will be successful. If, after good faith discussions and efforts to accommodate the later-filed registration, Phase Two coordination is not successful, the later-filed registration will be dismissed.
