Guide to Cell phone Signal boosters
The main purpose cell phone signal booster is to take an existing mobile signal, typically found outside your residence, office or car, amplify the signal and then broadcast it to an arena which has weak or no signal at all. A cell phone signal booster panel consists of an external antenna, a useful signal boosting amplifier and an internal antenna, with cables being connected to all the components. On a very rare note, like the limited edition booster, the amplifier and internal antenna are one single unit, but most of the time the three components are separate.
Cell phone signal boosters are made to attract an existing signal, amplify it, and broadcast to a space that is receiving poor or no signal at all. In order for the system to work properly, there must be an existing, strong signal to receive and amplify. Cell phone signal boosters are not able to generate signal, they only amplify and transmit cell phone signal bars, so if you fail to place an external antenna in a location that has a strong signal levels, then a cell phone signal booster will not work effectively
Booster providers arrange cell phone signal booster sets by the square footage that they are able to cover in best possible circumstances. An ideal circumstance is defined as having a very prominent signal for the external antenna, and in the best possible location there is placed the internal antenna, so there are no major hurdles to prevent the signal from being broadcasted to the entire area which requires coverage.
The stability of the cell phone signal where you plan to place the external antenna directly figures out how large of an area you're able to cover inside of your residence, office, or car. If you have a stable external signal, you'll be able to cover an area similar in size to the ideal proposed coverage area of the signal booster. If you have a quite poor external signal, the inside coverage area will be much to be precise, which may require that you replace a stronger system to obtain necessary coverage. Always keep this in mind when looking at the promised square foot coverage that is listed for each signal booster.
Interpreting what the bars mean on your phone is also very important when gauging how strong the signal is where you're going to set the external antenna. While there's no provided ground rule for displaying cell phone signal with bars on a phone, and some phones display more or less than the standard 5 bars, the rule of thumb still prevails that each bar of signal is roughly 5 to 10 times the power of the earlier bar. This is why it is a must for people who experience weak signal, such as two, one bars, to consider a powerful cell phone signal booster than what is recommended for their residence coverage area.
Amplifier ranges are displayed in decibels (dBs), which is a way of measuring how strong and reachable they are. Decibels are a logarithmic mean of measurement, which means that for every 3 decibel that boosts, the amplifier actually doubles in intake (which also means for every 3 dB decrease, it is being half strong). If you're amplifying a low signal and want to be sure that you'll cover the full area, choosing a powerful amplifier can be the ultimate solution.
There are two different models of external antennas that you'll come across when deciding to get a cell phone signal booster. One of them is Omni-directional and the other - Yagi directional:
Omni-directional antennas are set to send and receive signal in all directions, so you will be able to reach multiple cell phone towers at the same time and increase cell phone signal for many providers. If you have a medium to high signal range in the area that you're going to be placing your external antenna, then an Omni antenna is ideal for your requirement.
Yagi antennas are set to send and receive signal in a more specific of a direction, so while you're not able to cover a wide area, you will be able to cover greater area to mobile towers that you would not be able to with a previously mentioned Omni antenna. If you're going to be setting up your external antenna in an area which has poor signal range, and you are looking to boost only one cell provider’s signal, then a yagi antenna is the ideal pick for you.
