902 mhz study sought

''Adopt no rules without further study,'' the ARRL has recommended to
the FCC, in a Commission proposal to expand the use of Automatic
Vehicle Monitoring (AVM) systems in the 902-928 MHz band.

The proposal, in PR Docket 93-61, would allow the  expansion of AVM
systems through the creation of a new location and monitoring
service (LMS) in the 902-928 MHz band. Amateurs already share this
band with government radiolocation, fixed, and mobile services, in
addition to industrial, scientific, and medical (ISM) equipment and
various non-licensed, low-power ''Part 15'' devices.

The FCC said in its Notice of Proposed Rule Making that such an
expansion of AVM in this frequency range ''could lead to rapid
congestion of available spectrum'' and asked current users of the
band if they could handle any increased congestion.

''If not,'' the FCC said, ''commenters should offer potential
solutions, short of removing Part 15 users and amateur operations
from the band, restricting where such users could operate in the
band, or placing stricter limitations on the operations in this
band.''

The League said that no action should be taken until the FCC has
studied the potential for interaction between AVM and wind profiler
radar systems, the suitabliity of AVM operations for highway safety
sytems in a crowded RF environment, and the alternative technologies
available for the same purpose served by AVM and Location and
Monitoring Services.
