Nothing more irritating then it when you are an online important call discussing an important issue with your friends and both of you end up saying hello-hello to each one. This happens due to no mobile network and is known as call dropping. Here in this post, I have discussed all the top reason that is responsible for call drop or network problem that usually happens when and we are in a call.
Following are the important reason for the dropping of calls
Your signal strength is weak
Weak signals are the number one cause of calls dropped and data problems, for example, if you are far away from your mobile phone tower, signal weakening is more likely to occur in this case. Generally, the closer you are to a cell phone tower the better your signal will be.
In an ideal situation, your phone may be able to work with the tower that is about 45 miles or 72 kilometres away. Note that the data signals are affected by the line of sight so if you’re on the top of the mountain, you’ll probably get a better signal than if you’re in a forest. Even if you are far from a tower in the flat area, the Earth’s curvature will also affect the quality of the signal, which is because physical obstructions deflect and block radio signals.
Cell phone signals are so variable that you can find a dead spot in the 3-foot radius where there is a signal.
signals are affected due to rains
Wind does not affect signals, nor does it affect vehicle speed or Bluetooth signals that work at different frequencies. On the other hand, rain is a signal killer because the high-frequency wavelength used by cell phones does not travel through water. Water turns to block the radio signal between the cell phone tower and your phone, snow, and hail are also problematic, but they have lower water content. Temperature also can affect signals because warm air can hold more water vapour, more vapours mean there is a greater chance of signal attenuation.
Here’s an interesting fact; since tree leaves contain so much water they are excellent signal blockers and that’s why you may have a strong signal in the forest during winter when leaves fall but not during summers when more leaves are on the trees.
Due to overloading of Cell Towers
Signal strength and signal quality are both important when it comes to affecting your calls and network congestion is a major quality issue. In cases of extremely high traffic, such as a big concert or a Football or Cricket game or large-scale emergency, there is a sudden increase in network traffic, which interferes with the network and leads to calls and data signals being dropped.
Because of high traffic overloading occurs and this is why in densely populated areas you can find more cell towers compared to rural areas where there is less population. When there is more traffic on one cell tower then it transfers the overload to the other nearby towers, this process is sometimes called breathing and it is important to balance the traffic loads.
Wrong interpretation of signal strength
Your smartphone misinterprets some time signal strength, those little bars at the top of your phone give you a network signal approximation, but each phone varies by accuracy and there is also a lack of standardization among carriers.
Hence to get a better understanding of the network signal strength you can go into the settings in your phone to get a numerical value of signal strength which is represented by DBM meaning decimal milliwatts. On Android Smartphones you will find that in the network setting menu and with iPhones you have to go a bit deeper.
Signals are listed as negative numbers and you will typically see numbers or signal strength between -30 to -20 in real-world conditions, the closer your signal is to 0; the better the connection you get. Once the number drops to minus hundred or so you are likely to encounter Glitches and dropped calls, at -120 you basically have no usable signal.
Measures to take to encounter network problem or call drop
- Always keep your phone fully charged as a low battery can send your device to the power-saving mode and struggle to keep a connection.
- In case you don’t have a network problem, you can hold your phone to the length of your arm ; in a phenomenon called head and body loss, even your own body can reflect signals so that changing positions can help or just use a Bluetooth headset and set your phone aside to avoid this problem together.
- While you’re roaming, it means that you’re on another carrier’s towers and that they can and often slow down any roaming user’s data connection to maximize the experience for their own customers also realize that if your signal strength is too low then they drop your connection in this case in an effort to preserve bandwidth for users with a better signal.
- Sometimes a particular network operator is better in the area where you live, so it is recommended to take the services of that network operator who provides good networking services to your area.
- Sometimes it’s not your smartphone’s fault with the network signal, it’s the fault of your sim card that you’re using, so it’s recommended that you remove the SIM card and insert it into any other phone and check if the problem persists and get this sim card replaced by a new one.
- You should also try to change your position to a place next to the window if there is no signal problem to overcome this issue.
- Sometimes this no network problem exists because of the phone’s cheap quality because cheap phones are installed with poor antenna quality, which is why it is also advisable to purchase a phone where calling is smooth.
