§ 15.242 Operation in the bands 174-216 MHz and 470-668 MHz.
(a) The marketing and operation of intentional radiators under the
provisions of this section is restricted to biomedical telemetry devices
employed solely on the premises of health care facilities.
(1) A health care facility includes hospitals and other establishments that
offer services, facilities, and beds for use beyond 24 hours in rendering
medical treatment and institutions and organizations regularly engaged in
providing medical services through clinics, public health facilities, and
similar establishments, including governmental entities and agencies for
their own medical activities.
(2) This authority to operate does not extend to mobile vehicles, such as
ambulances, even if those vehicles are associated with a health care
facility.
(b) The fundamental emissions from a biomedical telemetry device operating
under the provisions of this section shall be contained within a single
television broadcast channel, as defined in part 73 of this chapter, under
all conditions of operation and shall lie wholly within the frequency ranges
of 174-216 MHz and 470-668 MHz.
(c) The field strength of the fundamental emissions shall not exceed 200
mV/m, as measured at a distance of 3 meters using a quasi-peak detector.
Manufacturers should note that a quasi-peak detector function indicates
field strength per 120 kHz of bandwidth ±20 kHz. Accordingly, the total
signal level over the band of operation may be higher than 200 mV/m. The
field strength of emissions radiated on any frequency outside of the
television broadcast channel within which the fundamental is contained shall
not exceed the general limits in § 15.209.
(d) The user and the installer of a biomedical telemetry device operating
within the frequency range 174-216 MHz, 470-608 MHz or 614-668 MHz shall
ensure that the following minimum separation distances are maintained
between the biomedical telemetry device and the authorized radio services
operating on the same frequencies:
(1) At least 10.3 km outside of the Grade B field strength contour (56
dBuV/m) of a TV broadcast station or an associated TV booster station
operating within the band 174-216 MHz.
(2) At least 5.5 km outside of the Grade B field strength contour (64
dBuV/m) of a TV broadcast station or an associated TV booster station
operating within the bands 470-608 MHz or 614-668 MHz.
(3) At least 5.1 km outside of the 68 dBuV/m field strength contour of a low
power TV or a TV translator station operating within the band 174-216 MHz.
(4) At least 3.1 km outside of the 74 dBuV/m field strength contour of a low
power TV or a TV translator station operating within the bands 470-608 MHz
or 614-668 MHz.
(5) Whatever distance is necessary to protect other authorized users within
these bands.
(e) The user and the installer of a biomedical telemetry device operating
within the frequency range 608-614 MHz and that will be located within 32 km
of the very long baseline array (VLBA) stations or within 80 km of any of
the other radio astronomy observatories noted in footnote US385 of Section
2.106 of this chapter must coordinate with, and obtain the written
concurrence of, the director of the affected radio astronomy observatory
before the equipment can be installed or operated. The National Science
Foundation point of contact for coordination is: Spectrum Manager, Division
of Astronomical Sciences, NSF Room 1045, 4201 Wilson Blvd., Arlington, VA
22230; tel: (703) 306-1823.
(f) Biomedical telemetry devices must not cause harmful interference to
licensed TV broadcast stations or to other authorized radio services, such
as operations on the broadcast frequencies under subparts G and H of part 74
of this chapter, land mobile stations operating under part 90 of this
chapter in the 470-512 MHz band, and radio astronomy operation in the
608-614 MHz band. (See § 15.5.) If harmful interference occurs, the
interference must either be corrected or the device must immediately cease
operation on the occupied frequency. Further, the operator of the biomedical
telemetry device must accept whatever level of interference is received from
other radio operations. The operator, i.e., the health care facility, is
responsible for resolving any interference that occurs subsequent to the
installation of these devices.
(g) The manufacturers, installers, and users of biomedical telemetry devices
are reminded that they must ensure that biomedical telemetry transmitters
operating under the provisions of this section avoid operating in close
proximity to authorized services using this spectrum. Sufficient separation
distance, necessary to avoid causing or receiving harmful interference, must
be maintained from co-channel operations. These parties are reminded that
the frequencies of the authorized services are subject to change, especially
during the implementation of the digital television services. The operating
frequencies of the part 15 devices may need to be changed, as necessary and
in accordance with the permissive change requirements of this chapter, to
accommodate changes in the operating frequencies of the authorized services.
(h) The manufacturers, installers and users of biomedical telemetry devices
are cautioned that the operation of this equipment could result in harmful
interference to other nearby medical devices.
