Sec.  22.401   Description and purposes of developmental authorizations.

   Eligible  entities  ( see  Sec. 22.7) may apply for, and the FCC may grant,
   authority to construct and operate one or more transmitters subject to the
   rules in this subpart and other limitations, waivers and/or conditions that
   may be prescribed. Authorizations granted on this basis are developmental
   authorizations. In general, the FCC grants developmental authorizations in
   situations and circumstances where it cannot reasonably be determined in
   advance whether a particular transmitter can be operated or a particular
   service can be provided without causing interference to the service of
   existing  stations.  For  example,  the  FCC  may  grant developmental
   authorizations for:

   (a) Field strength surveys to evaluate the technical suitability of antenna
   locations for stations in the Public Mobile Services;

   (b) Experimentation leading to the potential development of a new Public
   Mobile Service or technology; or,

   (c)  Stations transmitting on channels in certain frequency ranges, to
   provide  a trial period during which it can be individually determined
   whether such stations can operate without causing excessive interference to
   existing services.
