Sec.  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 detector.

   (2) In the 1395–1400 MHz and 1427–1429.5 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 1 MHz measurement
   bandwidth.

   (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 1427–1429.5 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.

   608.0–609.5 MHz

   609.5–611.0 MHz

   611.0–612.5 MHz

   612.5–614.0 MHz

   (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.
