How Does A Mobile Phone Work?

Mobile phones are everywhere and it is hard to find a person without one in today’s world. Although it is very common it is surprising that not every actually knows how the mobile phone works, from frequency to mobile network. Let me give you a short summary on how it happens. The phone is primarily used for voice communication and text messaging. Smart phones can send emails, gaming, Bluetooth and what not. Now that you know the functions here is how a normal mobile phone works and how you’re your voice communications work.

Most of the communication and information is sent through frequencies. Frequencies of the mobile system are division of small cells so that many people can use it at the same time. Some advantages of this frequency are increased capacity, reduction of power usage, less interference with other signals, etc.

Mobile networks need to recognize each phone and give them individuality so that another person can specifically contact that mobile phone. This is where sim card Singapore comes in to play. It is a smart card that can attach and removed anytime the user wants.

The user may change their mobile network if they want to. There are postpaid and quality prepaid sim cards. The difference is postpaid is paid end of the month after you have used and prepaid you need to pay first or top up and then use. The first two or three digits of the number are for the country code while the next two numbers are for the mobile network code and the rest is the identification number.

What happens when you make phone call or send a text is that your mobile phone adapts the voice, text, images, etc. into radio waves. Mobile phone base locations pass on and collect these signals and link the same to other receivers or networks where it was destined to go. The mobile network is separated in several cells and the denser the population the smaller the cells. Big cells are found in rural zones where the population is much lesser.

There several more techniques involved in this system and one of them is control channels. This channel makes sure that mobile device is known that a call is incoming and also monitors the signal of the device. If it moves away from a base station then it automatically checks and connects with next base with the best signal.

Although it may seem complicated, it is amazing how something like this has come to be in the lives every individual on earth. Life has changed dramatically.
