There are generally two reasons why an amplifier will turn off: oscillation, and handling too powerful a signal. Sometimes, your amplifier will shut itself off, and you may not understand why.
BEST ANTENNA BOOSTER FOR CELL PHONES INSTALL
If too much power is present, you may need to install an attenuator.Ĭell phone signal boosters are sophisticated pieces of equipment, and like any electronic device, can become overwhelmed. Too much, and the amplifier will automatically shut off. That’s what will determine how much signal the amplifier can take in and rebroadcast.
That’s what will determine how much stronger your signal becomes, and, essentially, how “loud” your amplifier can be. If you have a weak outdoor signal, pay close attention to your amplifier’s gain.Therefore, the maximum downlink power sets the maximum coverage area of the system when the amplifier has a good enough signal. This is why single-carrier solutions provide wider coverage for their designated carrier - they are able to focus all their power on amplifying those cellular frequencies assigned to that particular carrier, and give greatly enhanced gain.ĭownlink power is about coverage area, the maximum signal the amplifier can transmit inside a defined space, measured in dBm. Keep this in mind when comparing signal boosters. This also means for every - 3 dB decrease, the power is halved. Most home boosters will range from +60 to +70 dB, while commercial boosters will have +70 dB and better downlink power.ĭecibels are measured exponentially.
The more the gain, the more signal from the outdoor antenna is amplified. It simply measures how much the signal is amplified, using dB. What makes one amplifier different from another? There are two main variables that make the determination: gain and downlink power.
