» Tier 2 is designated as Priority Access License (PAL). The licenses for this service were auctioned in mid-2020 (Band 3550 – 3650 MHz).
» Tier 3 is the General Authorized Access (GAA) with administration by Spectrum Access System (SAS), who centrally coordinates access the shared spectrum, enforcing priorities and monitoring the incumbent operation for the RF environment.
» School Districts to provide Broadband Wireless Connection.
