The cell signal booster is gradually becoming the default solution for many problems related to bad cellular network connectivity. As more people are using cellular devices for various daily activities, good signal strength has become a necessity, and this is expected from carriers. Apart from personal use, this can also improve public safety, especially during emergencies like natural calamities, accidents, medical emergencies, etc. Having said that, many people are still unaware of signal boosters, and there are many doubts among consumers who use this device. The purpose of this article is to clarify doubts about cellular signal boosters.
What Does A Cellular Signal Booster Do?
The primary purpose of a cellular signal booster is to boost cell phone signals. With technologies like 4G and 3G, it also improves the speed of internet connectivity. Improved cellular connectivity reduces the battery consumption of mobile phones, gives better call quality, reduces missed calls, and the chances for call drops. Because of these reasons, it is ideal for your home, office, or another establishment. Also, this a bidirectional device, i.e. it can receive, as well as send signals from your cellular phone.
When Do You Need A Cellular Signal Booster?
The main situation to use a signal booster is when you need better call quality and data connectivity. Because of this, it is ideal for homes, offices, or another establishment where the cellular connectivity is poor. It is also useful for remote areas like villages and such places that are not properly served by cellular networks. Besides, it is ideal in situations where other solutions to improve call quality like using Wi-Fi and femtocells do not work. In short, a cellular signal booster can be considered a foolproof solution used for improving cellular connectivity.
What Are The Main Components Of A Cellular Signal Booster?
A cell signal booster has three main components and they are listed below.
- The outside antenna
- The amplifier or the booster
- The inside antenna
These three components are connected using coaxial cables, and the type of cable used affects the performance of the device.
What Are The Elements That Determine The Performance Of Your Cellular Signal Booster?
Decibels (dB): The strength of cellular signals is measured in the unit “dB”; It is a negative value that ranges from -50dB to -120dB. -50dB gives excellent signal strength and it is obtained near cellular towers; -120dB means no signal and it is usually obtained in dead zones. Keep in mind that the further you move away from the cellular tower, the greater the drop in signal strength. Signal boosters boost the signal by up to +25dB, i.e. it can increase connectivity in areas with poor signal strength like dead zones. Apart from the distance, other factors like construction materials, environment, geographical features, etc., also reduce the signal strength.
Donor Or Outside Antenna: Outside antennas of a cellular signal booster receive weak signals from nearby cellular towers. Because of this, the type and quality of the antenna affect the performance of the device. There are mainly two types, omnidirectional and unidirectional antennas. An omnidirectional antenna captures signals from all directions, i.e. 360o; a unidirectional antenna captures the signal from a single direction, i.e. its field of capture is limited to 90o. Because of this, the former is useful for receiving signals from multiple carriers, but it has a lower forward gain. The latter is ideal for receiving signals from a cellular tower far away because of its higher forward gain.
Amplifier: The weak cellular signal received by the outside antenna is boosted by the amplifier of the cellular signal booster. This depends on its gain, which is the amount by which the signal is boosted, and it is measured in decibels (dB). Apart from this, it increases the coverage area, and it ranges from 500 sq ft to 7500 sq ft. The gain of the device is adjusted depending on the coverage area required. The amplifier is the only component of the signal booster that requires a constant power supply. Besides, signal booster manufacturers design devices for different levels of indoor coverage, and they are listed below.
- Small work area, single room or office
- Small house or apartment
- Large house
Inside Antenna: It transmits the signal boosted by the amplifier to your mobile phone, as well as receives the signal from your phone and transmits it to the cellular tower. There are mainly two types of inside antennas dome antenna and panel antenna. The dome antenna transmits a boosted signal to a large area like the floor a building. A panel antenna is more suitable if you want to transmit the boosted signal to a smaller area like a room or any specific area of a floor.
Coax Cables: The performance of the cellular signal booster also depends on the length and impedance, i.e. the resistance of the cable. The longer the cable and the higher its impedance, the greater the loss in signal strength.
On a final note, ensure that the different components of the cell signal booster are compatible with the coax cables used; otherwise, it will negatively affect the performance of the device.
