Management of secondary operations in HF bands

In July 1997, the FCC granted to Terion (a.k.a., Flash Comm, Inc.) an unusual secondary licence to operate in the land mobile and fixed services portions of the high frequency radio spectrum. The licence was granted under waivers, since no rules existed for this type of service. As with the introduction of any new service, the HF community was concerned about the ability of the service to operate in a non-interference mode at HF. This presentation explains the conditions under which the FCC granted the license, and the methods Terion uses to comply with those conditions. The license itself allows Terion to construct and operate, on a secondary basis, a nationwide, commercial, two-way short-data messaging system in the HF range of the electromagnetic spectrum. But for the Wireless Telecommunications Bureau to grant such an authorization, the FCC had to waive several of its Part 90 rules
