Cellular dead zones are areas without adequate cellular network connectivity. The most common reason for cellular dead zones is the distance from the nearest cellular tower, and you can find such spots in remote areas like villages. Apart from this, you come across them when riding through underground tunnels, inside basements and elevators, during rains, at certain spots inside buildings, etc. Dead zones cause issues like dropped calls, absence of cellular network connectivity, choppy calls, and so on. Often, this can be fixed by installing a cell signal booster at your place; read on to know more about this device.
What Are The Causes For Cellular Dead Zone?
Cellular signals are radio frequency (RF) waves, and they are affected by the medium of their propagation, as well as obstacles in their path. Cellular dead zones are created when something blocks or attenuates the transmission of cellular signals between your cell phone and the cellular tower. Because of this, cellular devices will not be able to access strong enough signals, and hence they won’t function properly.
Listed below are the major reasons for the creation of cellular dead zones.
- Distance: When an RF signal originates from a cellular tower, it has the maximum signal strength. The closer you are to the tower, the greater the signal strength and vice versa. For instance, in remote areas like villages, you get a spotty cellular connection because you are far away from the nearest cellular tower.
- Environment And Geography: Environmental factors like temperature and humidity attenuates cellular signal strength. Also, mountains and hills have a similar effect because they absorb RF waves. So, these two factors create cellular dead zones if the signal is already weak.
- Construction Materials: Materials used for construction like glass, bricks, mortar, wood, and metal blocks attenuates cellular signals. This is the reason for the drop in signal strength or cellular dead zones inside tunnels, elevators, or old buildings.
How To Fix A Dead Zone?
The cellular signal strength ranges from -50 dBm to -120 dBm; -50 dBm is excellent, and -120 dBm is considered poor. If the cellular signal strength is between -110 dBm and -120 dBm, it creates dead zones, and your cell phone shows no signal. This can be fixed by installing passive distributed antenna systems (DASs), also known as cell phone service booster. They receive weak cellular signals, amplify them, and broadcast the boosted signal to your cellular device. Apart from amplifying the cellular signal, it also increases the coverage area of the cellular network where it is installed. This depends mainly on the outside signal strength and the gain of the amplifier.
If there is a cellular dead zone in your area, it can be easily fixed using a cell signal booster.
