Sec. 90.179  Shared use of radio stations.

    Licensees of radio stations authorized under this rule part may 
share the use of their facilities. A station is shared when persons not 
licensed for the station control the station for their own purposes 
pursuant to the licensee's authorization. Shared use of a radio station 
may be either on a non-profit cost shared basis or on a for-profit 
private carrier basis. Shared use of an authorized station is subject to 
the following conditions and limitations:
    (a) Persons may share a radio station only on frequencies for which 
they would be eligible for a separate authorization.
    (b) The licensee of the shared radio station is responsible for 
assuring that the authorized facility is used only by

[[Page 334]]

persons and only for purposes consistent with the requirements of this 
rule part.
    (c) Participants in the sharing arrangement may obtain a license for 
their own mobile units (including control points and/or control stations 
for control of the shared facility), or they may use mobile stations, 
and control stations or control points authorized to the licensee.
    (d) If the licensee shares the land station on a non-profit, cost 
shared basis to the licensee, this shared use must be pursuant to a 
written agreement between the licensee and each participant which sets 
out (1) the method of operation, (2) the components of the system which 
are covered by the sharing arrangements, (3) the method by which costs 
are to be apportioned, and (4) acknowledgement that all shared 
transmitter use must be subject to the licensee's control. These 
agreements must be kept as part of the station records.
    (e) If the land station which is being shared is interconnected with 
the public switched telephone network, the provisions of Sec. 90.477 et 
seq. apply.
    (f) Above 800 MHz, shared use on a for-profit private carrier basis 
is permitted only by SMR, Private Carrier Paging, LMS, and DSRCS 
licensees. See subparts M, P, and S of this part.
    (g) Notwithstanding paragraph (a) of this section, licensees 
authorized to operate radio systems on Public Safety Pool frequencies 
designated in Sec. 90.20 may share their facilities with Federal 
Government entities on a non-profit, cost-shared basis. Such a sharing 
arrangement is subject to the provisions of paragraphs (b), (d), and (e) 
of this section. State governments authorized to operate radio systems 
under Sec. 90.529 may share the use of their systems (for public safety 
services not made commercially available to the public) with any entity 
that would be eligible for licensing under Sec. 90.523 and Federal 
government entities.
    (h) Notwithstanding paragraph (a) of this section, licensees 
authorized to operate radio systems on Industrial/Business Pool 
frequencies designated in Sec. 90.35 may share their facilities with 
Public Safety Pool entities designated in Sec. 90.20 and with Federal 
Government entities on a non-profit, cost-shared basis. Such a sharing 
arrangement is subject to the provisions of paragraphs (b), (d), and (e) 
of this section.
    (i) The provisions of this section do not apply to licensees 
authorized to provide commercial mobile radio service under this part, 
including licensees authorized to use channels transferred or assigned 
pursuant to Sec. 90.621(e)(2).
    (j) On the Interoperability Channels in the 700 MHz Public Safety 
Band (See 90.531(b)(1)), hand-held and vehicular units operated by any 
licensee holding a license in the 700 MHz Public Safety Band or by any 
licensee for any public safety frequency pursuant to part 90 of the 
Commission's rules may communicate with or through land stations without 
further authorization and without a sharing agreement.
