Why Do Cellular Telephones Drop Calls?
It is one of the most aggravating events of todays society. Dropped phone calls never seem to happen on a non important phone call. Just wait until you get into the middle of a business call or you are talking to your child’s teacher at school, this is while the conversation is critical and there may not be a way to get back to the other party so easily, that is when our wireless telephones decide to drop the call.
Dropped phone calls are nothing new. They have been around since the beginning of mobile telephone history. One of the complexities of the mobile telephone system is that the phone is constantly trying to find a stronger signal or higher quality reception. The cell phone is trying to find a tower that might be closer. So as our mobile phones look for higher signal, usually while we are traveling, the phone will then try to move the phone call to a tower that might be a little closer to the mobile telephone. By moving the phone call to the closer tower the network is trying to provide you with higher quality phone calls.
As you might imagine, cellular telephone networks have a ton of subscribers. If you have ever driven during rush hour traffic, you can see numerous phone calls happening all at one time. This is where the problem lies. There are only so many channels for you to talk on. There is a limit to how a growing number of phone conversations can happen at once in a small geographical area.
As the phone and the cell phone network proceed to move your phone call, the network will look for a channel for you to talk on and there will not be one available. Your signal has weekend from the previous tower and you are fading, fading, no channels open…Oh. You just got dropped the call. What happened? There was no more space on the tower that you were trying to switch to. In some cases if you wait a few minutes, you can connect back to the network and complete your call. Even though your wireless phone may show excellent signal strength, if there are no channels to talk on then you will drop the call.
This is not the only issue that causes dropped phone calls, sometimes you can be in a bad area to start with. Trees and heavy vegetation will sometimes affect your call quality. One more issue may be the network might be having system problems in the location that you are currently at. One more possibility could be that you have defective equipment. Meaning that your cell phone has some internal damage on the boards causing it to lose reception.
If you are experiencing a lot of dropped calls with your current cellular phone provider you may want to examine switching your reception to a cellular company who has a reputation of good service in your area. Moreover, get your phone checked out by a certified technician at an authorized service center. This could save you the aggravation of dropping phone calls if the issue can be solved by simply purchasing some new equipment or having your existing phone repaired.
