Cellular towers emit some frequencies that might or might not affect the performance of a mobile signal booster. Whether or not these are emitted depends on how proximate the tower and the booster are to each other, plus the carrier of that cell site. To perform as well as possible, and to be safe from interferences that the cell site possibly causes, all mobile phone repeaters come with certain features. Shared below are some of those features that every booster must have, to achieve the aforesaid goals.
Automatic Gain Control
Also termed ‘AGC’, this is essentially a feature that controls cellular signal levels. Conventional boosters’ outside antenna receives the signals from cell sites, and it sends these signals in an amplified form to the internal antenna. The outside signal level established during the booster installation process would work as the one that determines the indoor cellular signal, in spite of the latter being in a state of flux. Several factors help to bring about this changeability, including seasonable changes and population increase. AGC aids in moderating this process in a way that avoids user intervention.
It automatically tweaks the indoor levels to try and match the continuously changing outside signals. So, when the latter signals are unusually low, the amplifier will work to offer better cellular signal indoors. Conversely, when those are unusually high, AGC will help to regulate the booster’s frequencies, to stop it from being overwhelmed and entering shutdown mode.
Excessively strong cellular signals coming from the nearest tower will cause oscillation, which is that ‘static’ noise you would occasionally hear when on a phone call. While oscillation may appear to be a good issue to have, the fact is that the interference is potentially as frustrating as having no cellular reception. The booster has to be capable of predicting oscillation to a certain extent. When oscillation goes beyond the norm, its detection in the amplifier will come into effect to keep the cellular interference from disrupting the equipment.
This feature is made to stop the oscillation or static in the booster-provided signal. When every other safeguard does not work, it will turn off to keep damage from happening. The act of it shutting down automatically will translate to unwanted downtime and many other inconveniences that are associated with it. Therefore, every booster has to have this particular feature.
