47 CFR §95.2573

1. (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.
2. (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.
3. (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.
4. (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.
5. (e)For MedRadio transmitters operating in the 2360-2400 MHz band, the maximum MedRadio emission bandwidth is 5 MHz.
6. (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.
