47 CFR § 95.2573 - MedRadio authorized bandwidths.
Each MedRadio transmitter type must be designed such that the MedRadio emission bandwidth (as defined in § 95.2503) does not exceed the applicable limits set forth in this section.
(a) For MedRadio transmitters operating in the 402–405 MHz band, the maximum MedRadio emission bandwidth is 300 kHz. Such transmitters must not use more than 300 kHz of bandwidth (total) during a MedRadio communications session. This provision does not preclude full duplex or half duplex communications provided that the total bandwidth of all of the channels employed in a MedRadio communications session does not exceed 300 kHz.
(b) For MedRadio transmitters operating in the 401–401.85 MHz band or the 405–406 MHz band, the maximum MedRadio emission bandwidth is 100 kHz. Such transmitters must not use more than 100 kHz of bandwidth (total) during a MedRadio communications session. This provision does not preclude full duplex or half duplex communications provided that the total bandwidth of all of the channels employed in a MedRadio communications session does not exceed 100 kHz.
(c) For MedRadio transmitters operating in the 401.85–402 MHz band, the maximum MedRadio emission bandwidth is 150 kHz. Such transmitters must not use more than 150 kHz of bandwidth (total) during a MedRadio communications session. This provision does not preclude full duplex or half duplex communications, provided that the total bandwidth of all of the channels employed in a MedRadio communications session does not exceed 150 kHz.
(d) For MedRadio transmitters operating in the 413–419 MHz, 426–432 MHz, 438–444 MHz or 451–457 MHz bands, the maximum MedRadio emission bandwidth is 6 MHz.
(e) For MedRadio transmitters operating in the 2360–2400 MHz band, the maximum MedRadio emission bandwidth is 5 MHz.
(f) Lesser emission bandwidths may be employed, provided that the unwanted emissions are attenuated as provided in § 95.2579. See also § 95.2567 regarding maximum radiated power limits, § 95.2565 on frequency accuracy, § 95.2569 on field strength measurements, and § 95.2585 on RF exposure.
