Mobile Phones Explained

by: Marco Barra

Even though the popularity of mobile phones is at an all time high, the complexity of the systems driving this technology usually means that only those involved with the industry have a complete understanding on how mobile phones actually work.

Until recently, and like most of today’s millions of mobile phone users, I found myself confused by the amount of information on the subject, and even when I found information which was relevant, the terminology used was best suited to someone with a degree in telecommunications.

In truth, the technology is very easy to understand when the information is presented in simple terms. In this article I’ll try to do just that – simplify the technology.

The concept:

Even though technology has become widely known as wireless, this is only true between your handset and your nearest receiving antenna. After that the connection goes through a series of telephone wires until it reaches the antenna nearest to the person you are calling – assuming the call is to another mobile.

Your handset and provider:

If you put features to one side, one handset works in much the same way to any other and the same is true of the actual network provider you choose to go with.

Manufacturers such as Nokia and Samsung dedicate themselves at producing the handsets and network providers such as Vodafone and O2 focus on the structure of the network itself.

Cellular networks:

The term “Cellular” has been derived from the fact that each antenna only has a reach of a limited area; this area is known as a cell. By placing antennas in various part of the country, providers have created Cellular network. The total area within these cells, determines the coverage of a network service provider.

Making and receiving calls:

When you make a call, your mobile phone locates the nearest antenna available for your network and connects you to the wired telephone system. The telephone network then locates the nearest antenna available for the person you are trying to call and connects you to that mobile. The opposite happens when you receive a call.

Your location:

For a connection to be successful, your network needs to know where your phone is located. To achieve this you mobile phone is in constant communication with your nearest antenna.

If you move location, and your original antenna no longer has enough reach to connect to your mobile, your phone will automatically search for another one. The new antenna then informs the system of your new location.

Conclusion

This article is by no means trying to undermine the achievements or the potential the technology has to offer. Instead, it is intended to provide an insight to the key elements of the mobile phone technology which would otherwise remain invisible to everyday users.
