Cell phone boosters are devices used to boost cellular signals to improve the quality of cellular communication. The three major components of a cell booster are the indoor antenna, amplifier, and the outdoor antenna. While reading the user manual of a signal booster or while going through a technical article about cellular signal boosters, you will come across various terms associated with the device.
In this article, we’ll explain the basic terminology so that the next time you study a user manual or read an article about cell phone booster, you can comprehend it better.
Basic Cellular Signal Booster Terminology
The basic cell phone booster terms are listed below.
Radio Frequency: It denotes any frequency that is used to transmit wireless radio signals including cellular signal, FM and AM radio, and WiFi signals.
Downlink Signal: The signal that is sent from the cell tower to your cell phone.
Uplink Signal: The signal that is sent back to the cell tower from your phone.
Gain: Gain refers to the extent to which the signal is boosted by the amplifier. Gain is usually expressed in decibels. The higher the value of gain, the better is the performance of the booster. 0 dB gain means that the signal wasn’t boosted at all. When the gain is 10 dB, it indicates the boosted signal is 10 times the original signal strength and 20dB gain indicates that the boosted signal is 100 times the original signal.
Antenna Gain: Gain is not exclusive to an amplifier. The antennas of signal boosters also have respective gain. But their gain does not mean that they amplify the signal. Antennas perform the task of sending and receiving cellular signals and that is all they do. Boosting the signals is the function of the amplifier. The gain of antennas is expressed in dBi, which too is measured in logarithmic scale like amplifier gain.
Attenuation: This refers to the loss of signal strength on traveling over a distance. It is expressed in dB and is a negative value since it measures the loss in signal strength. Attenuation of -10dB indicates that the signal is 10 times weaker than the original signal.
Signal Strength: The strength of a wireless signal is measured in the unit dBm, which too is logarithmic. 0 dBm corresponds to 1 milliwatt signal, 30 dBm corresponds to 1 watt, and so on.
Understanding signal booster terminology will be of great help if you are planning to install a cell phone booster in your home or business.
