Cell phone booster attempts to increase the strength of cellular reception by amplifying the available cellular signals and rebroadcasting them to reception points. However, the output power of signal boosters needs to be regulated to ensure its failsafe operation.

What Is Meant By Attenuation?

Reducing the output power of the signal booster is referred to as attenuation. The extent of attenuation depends on the size of the building and the strength of available cellular signals. Attenuation is performed to maximize the coverage area of the signal booster by removing or adding power to the booster.

Excess power leads to the oscillation between the internal and external antenna of the cellular signal booster. On the other hand, too little power would result in a small coverage area. In addition to regulating output power, attenuation is also employed to prevent the overflow of signals beyond the walls of buildings and achieve efficient antenna separation.

The attenuation step can be performed manually using dip switches. Some boosters have AGC(Automatic Gain Control) that automatically adjusts the power of the booster system. Dip switches used for manual attenuation are simply turned off and on to control the power of the system. Other sources too can be used for manual attenuation.

Attenuating A Signal Booster Manually

Dip switches used for attenuation control the downlink and uplink separately. The downlink refers to the cellular signal that comes from the transmitting tower to the cell phone whereas uplink refers to the signal that goes from cell phone to tower.

Other means of manually attenuating the cell phone booster are:

  • Cable: You should use the lowest loss cable to get the best signal.
  • Attenuators: In-line attenuators are added to the cable-run in order to reduce the signal strength by ranges 5dB,10dB, or 20dB.
  • Dials: The operation of dials is similar to that of dip switches. However, instead of flipping the switches between on and off mode, you have to twist the dial in attenuation using dials.

Advantages Of Dip-Switches

The ability to attenuate one band without affecting any of the other bands is the primary advantage of dip switches. Flaws in indoor cellular coverage, inadequate separation of antennas, and overpowering can be efficiently handled using dip switches. Signal boosters that can be attenuated manually will have a dip-switch bank, groups of dip-switches.

Attenuation gives better control over the operation of cell phone booster.
