§ 90.353 LMS operations in the 902-928 MHz band.
LMS systems may be authorized within the 902-928 MHz band, subject to
the conditions in this section. LMS licensees are required to maintain
whatever records are necessary to demonstrate compliance with these
provisions and must make these records available to the Commission upon
request:
(a) LMS operations will not cause interference to and must tolerate
interference from industrial, scientific, and medical (ISM) devices and
radiolocation Government stations that operate in the 902-928 MHz band.
(b) LMS systems are authorized to transmit status and instructional
messages, either voice or non-voice, so long as they are related to the
location or monitoring functions of the system.
(c) LMS systems may utilize store and forward interconnection, where
either transmissions from a vehicle or object being monitored are
stored by the LMS provider for later transmission over the public
switched network (PSN), or transmissions received by the LMS provider
from the PSN are stored for later transmission to the vehicle or object
being monitored. Real-time interconnection between vehicles or objects
being monitored and the PSN will only be permitted to enable emergency
communications related to a vehicle or a passenger in a vehicle. Such
real-time, interconnected communications may only be sent to or
received from a system dispatch point or entities eligible in the
Public Safety or Special Emergency Radio Services. See subparts B and C
of this part.
(d) Multilateration LMS systems will be authorized on a primary basis
within the bands 904-909.75 MHz and 921.75-927.25 MHz. Additionally,
multilateration and non-multilateration systems will share the
919.75-921.75 MHz band on a co-equal basis. Licensing will be on the
basis of Economic Areas (EAs) for multilateration systems, with one
exclusive EA license being issued for each of these three sub-bands.
Except as provided in paragraph (f) of this section, multilateration EA
licensees may be authorized to operate on only one of the three
multilateration bands within a given EA. Additionally, EA
multilateration LMS licenses will be conditioned upon the licensee's
ability to demonstrate through actual field tests that their systems do
not cause unacceptable levels of interference to 47 CFR part 15
devices.
(e) Multilateration EA-licensed systems and grandfathered automatic
vehicle monitoring service (AVM) systems ( see § 90.363) are authorized
on a shared basis and must cooperate in the selection and use of
frequencies in accordance with § 90.173(b).
(f) Multilateration EA licensees may be authorized to operate on both
the 919.75-921.75 MHz and 921.75-927.75 MHz bands within a given EA (
see § 90.209(b)(5)).
(g) Multilateration LMS systems whose primary operations involve the
provision of vehicle location services, may provide non-vehicular
location services.
(h) Non-multilateration stations are authorized to operate on a shared,
non-exclusive basis in the 902-904 MHz and 909.75-921.75 MHz sub-bands.
Non-multilateration systems and multilateration systems will share the
919.75-921.75 MHz band on a co-equal basis. Non-multilateration LMS
systems may not provide non-vehicular location services. The maximum
antenna height above ground for non-multilateration LMS systems is 15
meters.
(i) Non-multilateration LMS licenses will be issued on a site-by-site
basis, except that municipalities or other governmental operatives may
file jointly for a non-multilateration license covering a given U.S.
Department of Commerce Bureau of Economic Analysis Economic Area (EA).
Such an application must identify all planned sites. After receiving
the license, the non-multilateration EA licensee must notify the
Commission if sites are deleted or if new sites are added, before those
sites may be put into operation.
