In the present time, almost everyone uses mobile phones and other smart devices daily. Because of this, it is important to have good cellular network connectivity. However, occasionally we come across snags like weak signal strength that causes issues like dropped calls, slow internet speeds, bad call quality, etc. One of the best solutions to avoid this is to use a cell phone service booster authorized by your carrier. In this article, we focus on the different aspects that affect the functioning of this device; read on to know more about them.
An Introduction About Cell Signal Booster
Cell signal boosters receive weak carrier signals, amplifies them, and retransmits to your mobile phone so that you can enjoy uninterrupted services. These devices have three critical components, the outside antenna, the amplifier, and the inside antenna. The output of the device depends on the type of outside antenna used, and its coverage area depends on the gain of the amplifier. Also, keep in mind that, when installing it, a minimum separating distance must be kept between these two antennas. This is to avoid the formation of a positive feedback loop, and this phenomenon is called oscillation. It affects other cellular devices in its vicinity, as well as damages the cellular tower.
Reasons For Weak Cellular Signal Strength
Cellular signals are radio waves, and they are affected by various factors independently or in combination. This results in weak reception causing issues like dropped calls, slow data speed, dead zones, etc. Some of the common causes of weak cell signal reception are:
- Distance From Cellular Tower: Distance from the cellular tower is one of the most common reasons for weak signal reception. The further you are from the tower, the weaker the signal strength and vice versa. Also, it affects the downlink and uplink of the device.
- Geography: Geographical features like hills, valleys, mountains, forest, etc., attenuates cellular signals.
- Weather: Climatic factors like temperature, humidity, precipitation, and wind affects cellular signal strength. For example, water droplets in the atmosphere deflect radio waves, and this results in decreased signal strength. Likewise, in autumn when trees shed leaves, reception increases. But when they grow leaves in the spring, reception is reduced. This is because the water in plants has dissolved electrolytes; this hinders the transmission of cellular signals.
- Construction Materials: The materials used in construction like bricks, plywood, concrete, metal wires, glass, etc., hinders the propagation of cellular signals resulting in weak signal strength. Likewise, materials used for building automobiles parts like body, windshield, etc., also have a similar effect.
- Interference: The interference between towers is one of the most common causes of weak cellular signal strength. This is because, for technologies like 4G LTE, carriers use the same frequency bands to transmit carrier waves. So, if your phone is located between towers transmitting at almost equal strength, it causes interference, resulting in lower signal quality. This is more common in urban and suburban areas due to the presence of cellular towers of multiple carriers near each other.
The best way to avoid weak cellular signal reception indoors due to the reasons mentioned above is to use a cell phone service booster. However, these devices do not work well outdoors because of open-air path loss. In such situations, you can get good signal strength only if you are right next to the antenna. These devices are meant to be used in locations with underdeveloped cellular network infrastructure like remote areas and villages. Also, keep in mind that strong signal strength overloads the amplifier, lowering the performance of the device.
Signal Strength And Signal Quality
The performance of the cell phone service booster depends on the strength of the input signal, and it is measured in decibel milliwatts (dBm). Also, keep in mind that the gain of the amplifier of the device is adjusted according to this so that you get the optimal output.
The amplifier is the most important component of a signal booster, and its performance is determined by its gain and downlink output power. Gain measures how much the signal is amplified, and its unit of measurement is decibel or dB; the higher the gain, the more amplification, and vice versa. Downlink output power is the maximum power with which it can retransmit the boosted signal, and it determines the coverage area as well. Finally, choosing between these two factors depends on the strength of the signal received by the donor antenna.
If the input signal is less than -80 dBm, then the amplifier will not reach its maximum downlink output power. So, you must choose an amplifier with maximum gain. But if the signal is strong, i.e. more than -70 dBm, the amplifier easily reaches maximum output power. In this situation, you must focus on the downlink output power of the device.
On a final note, more and more people are using cell signal boosters because of their rising popularity. When purchasing a signal booster you must ensure that it is a certified product to avoid issues like oscillation.
