§ 95.1115 General technical requirements.
(a) Field strength limits. (1) In the 608-614 MHz band, the maximum
allowable field strength is 200 mV/m, as measured at a distance of 3
meters, using measuring instrumentation with a CISPR quasi-peak
(2) In the 1395-1400 MHz and 1427-1432 MHz bands, the maximum allowable
field strength is 740 mV/m, as measured at a distance of 3 meters,
using measuring equipment with an averaging detector and a 1MHz
(b) Undesired emissions. (1) Out-of-band emissions below 960 MHz are
limited to 200 microvolts/meter, as measured at a distance of 3 meters,
using measuring instrumentation with a CISPR quasi-peak detector.
(2) Out-of-band emissions above 960 MHz are limited to 500
microvolts/meter as measured at a distance of 3 meters, using measuring
equipment with an averaging detector and a 1 MHz measurement bandwidth.
(c) Emission types. A wireless medical telemetry device may transmit
any emission type appropriate for communications in this service,
except for video and voice. Waveforms such as electrocardiograms (ECGs)
are not considered video.
(d) Channel use. (1) In the 1395-1400 MHz and 1427-1432 MHz bands, no
specific channels are specified. Wireless medical telemetry devices may
operate on any channel within the bands authorized for wireless medical
telemetry use in this part.
(2) In the 608-614 MHz band, wireless medical telemetry devices
utilizing broadband technologies such as spread spectrum shall be
capable of operating within one or more of the following channels of
1.5 MHz each, up to a maximum of 6 MHz, and shall operate on the
minimum number of channels necessary to avoid harmful interference to
any other wireless medical telemetry devices.
(3) Channel usage is on a co-primary shared basis only, and channels
will not be assigned for the exclusive use of any entity.
(4) Authorized health care providers, in conjunction with the equipment
manufacturers, must cooperate in the selection and use of frequencies
in order to reduce the potential for interference with other wireless
medical telemetry devices, or other co-primary users. Operations in the
608-614 MHz band (television channel 37) are not protected from
adjacent band interference from broadcast television operating on
channels 36 and 38.
(e) Frequency stability. Manufacturers of wireless medical telemetry
devices are responsible for ensuring frequency stability such that an
emission is maintained within the band of operation under all of the
manufacturer's specified conditions.
