The mobile phone is one of the most important devices by which everyone can stay connected with one another socially in the world not only by calling but also by messaging, sending emails, video calling, etc. And no argue with the fact that this is our way of staying connected to each other. But the biggest hindrance of our communication is Dropped Phone Calls. This is a very familiar problem in society. And that is the thing that almost everyone is frustrated about. A recent study by Pew Internet & American Life Project suggested dropped phone calls were most cited as the biggest complaint by cell phone owners. Another study claimed, 72% of cell phone owners experienced dropped calls at least occasionally and other 28% experienced at least a few times in a week. So that’s definitely not a few numbers of people who are frustrated for this problem. Now let’s know what are the real reasons behind this irritating problem and can we make a try to reduce the problem personally?
Mobile phones are an advanced version of two-way radios. Maybe the bandwidths and frequency are different, communication techniques are also different but the concept is the same as the old two-way radios. That means mobile phones also suffer from the effects of interference just like FM/AM radios.
Signal weakening is one of the principal reasons for call drops. Theoretically and ideally, a phone can be worked with a tower that is maximum 45 miles (72 Km) away but in reality, that distance is reduced to just 2 or 3 kilometers in rural areas and only 400-800 meters in urban areas because the data signal is affected by the huge buildings, trees, hills or mountains, population, traffic and even by the curvature of the earth! These are the obstacles in the way of the data signal from a cell phone tower to cell phone to cause weak signals. That’s why signals become weak and phone calls drop. On the other hand, the signal range is also dependent on what type of network you use. 2G networks penetrate with maximum range whereas 3G does less than that and 4G does the least. So that means the closer you are with your phone to a tower, the better your phone’s signal and vice versa and also if you have a 2G network in your phone, the possibility of getting stronger data signal increases.
Overload Of Cell Phone Towers
When many people try to connect networks at the same time, the nearby towers become overloaded with huge traffic. For this reason, those overloaded cell phone towers transfer some to other available towers to reduce their overloading. And that is another important reason for call dropping because when your device’s signal is transferred by a nearby tower to another farther tower, the signal quality may be enhanced but the signal strength is naturally reduced to cause call dropping.
Know the Actual Signal Strength
We all know how to check signal status. We have to just notice the graphical bars on the right side of the phone’s display to know the signal status. But do those bars really show the accurate signal? No, absolutely not. Most of the people don’t know how to check the accurate signal status in a device. You have to open the settings > about phone > status > SIM status > signal strength and then you will get a numerical value that is represented by dBm (decibel milliwatts). The number stays in negative form i.e. -56 dBm. Basically, you may see numbers between -30 to -120. The closer the number is to 0, the better the connection. Suppose the number is -78 dBm that means it is a great connection and there is no chance of dropping phone calls. On the other side, if that number exceeds -100 dBm, you are most likely going to experience dropped calls and unstable network connection. So, it will be better not to call someone when the number of signal status is high enough.
Rain, The Signal Assassin
Rain is another reason for call drops. When it is raining in your locality, you will notice very often that data signal is unstable and every time you are trying to call someone, it disconnects. The reason behind this is, high-frequency wavelengths of cell phones cannot pass through water properly because water blocks the data signal from a cell phone to a cell phone tower. That’s why when it rains, the network signal becomes lost. Snowfall and hail also block the signal but as they contain less water vapor, they are less problematic for the network. Even warm wind affects the data signal as it carries a significant amount of water vapor. That means more water vapor indicates an increased chance of signal blocking and that leads to drop calls.
Tree leaves contain so much water and for this reason, they also can kill the signals. For real-life experience, if you go to a forest in summer, then you must find an unstable network signal but if you go in winter when the leaves have already fallen, you may get a stronger network connection.
In the last point, the one thing we notice is that nature and weather have also an adverse effect on our network connection. In some particular time, they are responsible for call dropping very often.
