What is the difference between the two BDAs: Class A Channelized vs. Class B Band Selective?
Both BDA/Fiber DAS systems strengthen certain frequency bandwidths or ranges.
Class A:
- BDA is classified by the FCC as Class A if the bandwidth is less than 75 kHz.
- Channelized Signal Boosters are BDAs that amplify numerous <75 kHz channels. Class A can lessen the effects of near-far communications.
Class B:
- The FCC classifies BDAs with bandwidths greater than 75 KHz as Class B. Before being deployed, Class B Signal Boosters need to be officially registered with the FCC.
- More popular, class B amplifiers are capable of simultaneously covering every channel in the public safety bands operating at 800 and 700 MHz.
