Report No. DC 95-78        ACTION IN DOCKET CASE               June 8, 1995


          FCC PROPOSES TO AMEND PARTS 22, 90, AND 94 OF THE RULES
                 TO PERMIT ROUTINE USE OF SIGNAL BOOSTERS
                           (WT DOCKET NO. 95-70)

     TX RX Systems, Inc., has asked the Commission to amend Parts
22, 90 and 94 of the  rules and regulations to permit routine use
of one-way or two-way signal boosters.   This proposal would
permit licensees to routinely use signal boosters in Part 22
common carrier paging operations, Part 90 land mobile radio  and
paging operations, and Part 94 multiple address system
operations.

     A signal booster is a device that receives an incoming
signal, amplifies it and retransmits it on the same frequency. 
Such devices are used to improve communications in locations
within the normal coverage area of a radio system where the
signal is blocked or shielded due to natural terrain or man-made
obstacles.  For example, a signal booster may be used in such
locations as valleys, tunnels, below-ground parking facilities,
or inside cargo vessels and aircraft hangers.

     Currently, under Part 90 Private Land Mobile Radio Service
rules, signal boosters may be used only on 10 Business Radio
Service frequency pairs in the 450-470 MHz band for
communications related to the servicing and supplying of aircraft
at certain specified airports.  Under Part 22 Public Mobile
Service rules, a form of signal booster, generally called a
cellular repeater, may be used by cellular licensees without
separate licensing provided that the repeater does not extend the
licensee's signal beyond the authorized cellular service area.

     The Commission has proposed to expand the use of signal
boosters to Part 22 common carrier paging operations at 931-932
Mhz; to Part 90 land mobile radio operations in all Part 90
frequency bands above 150 MHz; to Part 90 paging operations at
929-930 MHz; and to Part 94 multiple address system operations in
the 928-960 MHz band.  The Commission proposed to define a signal
booster as a device that automatically receives, amplifies, and 

                                  -more-



                                    -2-

retransmits on a one-way or two-way basis, the signal received
from base stations, mobile, and portable units, with no change in
frequency or authorized bandwidth.  

     The Commission would classify boosters as either narrowband
(Class A), in which case the booster amplifies only those
discrete frequencies intended to be retransmitted, or broadband
(Class B), where all signals within the passband of the signal
booster filter are amplified.  The Commission further proposed
that licensees may employ either Class A or Class B signal
boosters as required, be responsible for eliminating any harmful
interference that the signal booster may cause to other
licensees, and for ensuring that the basic authorized coverage
areas is not expanded.

     Comments are invited.

     Action by the Commission May 17, 1995, by Notice of Proposed
Rulemaking (FCC 95-204).  Chairman Hundt, Commissioners Quello,
Barrett, Ness, and Chong.
