# §95.2573. MedRadio authorized bandwidths.


Each MedRadio transmitter type must be designed such that the MedRadio emission bandwidth (as defined in [§ 95.2503](/cfr/47/95.2503.md)) 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](/cfr/47/95.2579.md). See also [§ 95.2567](/cfr/47/95.2567.md) regarding maximum radiated power limits, [§ 95.2565](/cfr/47/95.2565.md) on frequency accuracy, [§ 95.2569](/cfr/47/95.2569.md) on field strength measurements, and [§ 95.2585](/cfr/47/95.2585.md) on RF exposure.
