   Authorized frequency. The frequency assigned to a station by the
   Commission and specified in the instrument of authorization.

   Authorized power. The power assigned to a radio station by the
   Commission and specified in the instrument of authorization.

   Experimental radio service. A service in which radio waves are employed
   for purposes of experimentation in the radio art or for purposes of
   providing essential communications for research projects that could not
   be conducted without the benefit of such communications.

   Experimental station. A station utilizing radio waves in experiments
   with a view to the development of science or technique.

   Harmful interference. Any radiation or induction that endangers the
   functioning of a radionavigation or safety service, or obstructs or
   repeatedly interrupts a radio service operating in accordance with the
   Table of Frequency Allocations and other provisions of part 2 of this

   shelter, servicing, or repair of aircraft, or for receiving or
   discharging passengers or cargo.

   Market trial. A program designed to evaluate product performance and
   customer acceptability prior to the production stage, and typically
   requires testing a specific product under expected use conditions to
   evaluate actual performance and effectiveness.

   Open Area Test Site. A site for electromagnetic measurements that has a
   reflective ground plane, and is characterized by open, flat terrain at
   a distance far enough away from buildings, electric lines, fences,
   trees, underground cables, pipelines, and other potential reflective
   objects, so that the effects due to such objects are negligible.

   Person. An individual, partnership, association, joint stock company,
   trust, corporation, or state or local government.

   Product development trial. An experimental program designed to evaluate
   product performance (including medical devices in clinical trials) in
   the conceptual, developmental, and design stages, and typically
   requiring testing under expected use conditions.
