Many readers have been asking what the gain and power parameters of a mobile signal repeater signify in terms of performance. How are they related? What should you consider when choosing a mobile signal repeater? This article will clarify the gain and power of mobile signal repeaters. As a professional manufacturer of mobile signal repeater for 12 years, we will tell you the true.

Understanding Gain and Power in Mobile Signal Repeaters
Gain and power are two key parameters for mobile signal repeaters:
Gain
Gain is typically measured in decibels (dB) and represents the extent to which the repeater boosters the signal. Essentially, a mobile signal booster, also known as a mobile signal repeater, relays signals from areas with good reception to those with weaker signals. The gain addresses the issue of mobile signal attenuation that occurs during transmission through cables.
When the antenna receives cellular signals, the signals may experience varying degrees of loss during transmission through cables or splitters. The further the signal needs to be relayed, the higher the gain required from the mobile signal repeater. Under the same condition, a higher gain means the repeater can relay signals over longer distances.
Therefore, the following statement often found online is incorrect: Gain primarily reflects the repeater’s ability to enhance signals. A higher gain indicates that even weak cellular signals can be significantly amplified, thereby improving signal quality.
For long-distance signal transmission, we recommend using fiber optics as a transmission medium, as fiber optic repeaters incur far less signal attenuation than traditional coaxial cables.
Power
Power refers to the strength of the output signal from the repeater, typically measured in watts (dBm/mW/W). It determines the coverage area of the signal and its ability to penetrate obstacles. Under the same condition, a higher power rating results in a wider coverage area.

How Are Gain and Power Related?
These two parameters are not inherently linked, but generally, a mobile signal repeater with higher power will also have a higher gain.
What to Consider When Choosing a Mobile Signal Repeater?
Understanding these two parameters helps in selecting a mobile signal repeater suitable for specific applications:
1. Focus on the frequency bands that need amplification. The commonly used bands today include GSM, LTE, DSC, WCDMA, and NR. You can contact your local carrier for information, or check the cellular signal bands using the methods provided below.
2. Identify a location with good signal reception, and use your phone with testing software to measure the signal strength. iPhone users can find simple tutorials through Google, while Android users can download the Cellular Z app from the app store for signal testing.
RSRP (Reference Signal Received Power) is a standard measure for evaluating signal smoothness. Generally, values above -80 dBm indicate very smooth reception, while values below -110 dBm indicate almost no network connectivity. Typically, you should aim for a signal source below -100 dBm.
3. Choose the appropriate mobile signal repeater based on the signal strength and the area that needs coverage.
In general, if the distance between the signal source and the target coverage area is greater, the attenuation caused by the cable will be higher, necessitating a repeater with greater gain.
For extensive coverage of cellular signals, you should opt for a mobile signal repeater with higher power.
