# §95.975. CBRS modulation limits.


Each CBRS transmitter type must be designed such that the modulation characteristics are in compliance with the rules in this section.

- (a) When emission type A3E is transmitted with voice modulation, the modulation percentage must be at least 85%, but not more than 100%.
- (b) When emission type A3E is transmitted by a CBRS transmitter having a transmitter output power of more than 2.5 W, the transmitter must contain a circuit that automatically prevents the modulation percentage from exceeding 100%.
- (c) When emission type F3E is transmitted the peak frequency deviation shall not exceed ±2 kHz.
