A part 90 signal booster belongs to the category of industrial signal boosters, but they are primarily used for Public Safety Operations and Private Land Mobile Radio (PLMR) services. This device can be used to improve cellular connectivity in an area. It receives a weak cellular signal, amplifies it, and broadcasts the boosted signal to cellular devices in its service range. Usually, these devices are bidirectional, i.e. transmits signals to and fro between cellular devices and cellular towers. Shared below are details about part 90 signal boosters; read on to know more about them.

What Are The Different Classifications Of Part 90 Signal Boosters?

There are mainly two classes of part 90 signal boosters: class A and class B.

  • Class A Signal Booster: All signal boosters with passbands that do not exceed 75kHz are considered class A. Also, it is designed to retransmit signals of one or more specific channels.
  • Class B Signal Booster: ALL signal boosters with passbands exceeding 75kHz are considered class B. Besides, it can retransmit signals from a wide range of frequency bands, and due to this reason, it must be registered with your respective telecom agency.

How To Select Between Class A And Class B Cellular Signal Booster?

The choice between class A and class B signal boosters depends very much on the local authority. The other factors that are taken into consideration are listed below.

  • Price: Class A signal boosters are more expensive than class B signal boosters with the same RF power output. This is because the former has higher levels of RF control and onboard intelligence than the latter. Also, there will be variations in class B devices depending on the vendor or manufacturer.
  • Setup: It is easier to set up class B signal boosters because of the fewer technical specifications that you must choose. For instance, these signal boosters do not allow the user to alter the bandwidth of the signal filter. On the contrary, class A devices allow for the selection of desired frequencies, bandwidth options, channel gain, squelch control, and so on.
  • Reliability: The reliability of class A and class B devices varies because of the differences in their performances. In class A signal booster, the signal filter filters out undesirable channels so that they do not take away the power of the amplifier required for important channels. So, they give a stable performance with minimal fluctuation in their output. Class B devices produce major fluctuations in their output because they accept wideband RF input. Hence, it is less reliable for public safety operations.

These are the major differences between class A and class B cellular signal boosters, and we hope that the details shared above were of use to you.
