A portion of the 902-928 MHz (33 centimeter) band may become less
useful to radio amateurs in urban areas as a result of an FCC
Order.
The FCC has given Progeny LMS, LLC consent to begin commercial
operation of its multilateration location and monitoring service
(M-LMS) in the upper portion
of the band. According to the FCC, Progeny’s location service is
designed to operate on approximately 4 megahertz — about one-half of
the M-LMS portions
of the band between 919.750 and 927.750 MHz — where Progeny holds licenses.

“Progeny is deploying a wide-area positioning system to provide more
precise location services in areas where Global Positioning System
(GPS) and other
existing services may not work effectively, particularly indoors and
in urban canyons,”
