Cell phone signal boosters (or cellular repeaters) are bidirectional amplifiers designed to boost the mobile phone reception using internal signal amplifiers, reception antennas and rebroadcast antennas. External antennas collect good cellular signal, and then it is transmitted to an amplifier, which retransmits the signal locally. This process results in much better signal.
Rural areas often have problems with bad signal. Most service providers won’t make new towers in rural areas, because housing density is low. Cell phone signal boosters can solve this problem.
Certain construction materials can block the signal. For example, people who live in buildings that have thick concrete or too much metal are likely to have problems with cellular signal. Fiberglass and solid foam insulation can also cause this problem.
Cell Phone Signal Booster Components
Most systems include internal monopole antennas. Equal distribution of the signal in all directions is considered the main advantage of an internal rebroadcast antenna.
Although there are models that don’t have an external directional antenna, this component is very important for signal strength. An antenna can be located outside in order to provide a good signal. Larger external antennas will provide much better signal, but smaller antennas can also improve the mobile signal strength.
All cell phone boosters have signal amplifiers. Some models can only provide gain between 20 db and 50 db, but there are also better (and more expensive) models that provide more than 50 db.
How Do Cell Phone Signal Boosters Work?
One device can be used by several cell phones at the same time. This makes cell phone signal boosters good for both home and commercial use. A cell phone booster can increase the phone’s battery life, because it is near the phone and less power is needed for broadcasting the signal to a bidirectional amplifier.
The outside antenna of a cell phone picks up the signal and then boosts it. The signal is sent to the amplifier that makes the signal even stronger. Then, it pushes the signal through the internal antenna.
The size of the area that will be covered can be calculated in advance. In fact, this is exactly what you need to do before you decide which product to buy. Another thing you should know is that cell phone signal boosters cannot create a signal in places where there is no any signal at all. What these devices can do is improve the strength of the existing signal. Sometimes, using a cell phone booster is the only way to enhance the signal in your home.
