Mobile Phones Explained

By: Marco Barra

Even though the popularity of mobile phones is at an all timehigh, the complexity of the systems driving this technologyusually means that only those involved with the industry have acomplete understanding on how mobile phones actually work.

Until recently, and like most of today's millions of mobilephone users, I found myself confused by the amount ofinformation on the subject, and even when I found informationwhich was relevant, the terminology used was best suited tosomeone with a degree in telecommunications.

In truth, the technology is very easy to understand when theinformation is presented in simple terms. In this article I'lltry to do just that - simplify the technology.

The concept: Even though technology has become widely known aswireless, this is only true between your handset and yournearest receiving antenna. After that the connection goesthrough a series of telephone wires until it reaches the antennanearest to the person you are calling - assuming the call is toanother mobile.

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

Manufacturers such as Nokia and Samsung dedicate themselves atproducing the handsets and network providers such as Vodafoneand O2 focus on the structure of the network itself.

Cellular networks: The term "Cellular" has been derived from thefact that each antenna only has a reach of a limited area; thisarea is known as a cell. By placing antennas in various part ofthe country, providers have created Cellular network. The totalarea within these cells, determines the coverage of a networkservice provider.

Making and receiving calls: When you make a call, your mobilephone locates the nearest antenna available for your network andconnects you to the wired telephone system. The telephonenetwork then locates the nearest antenna available for theperson 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 networkneeds to know where your phone is located. To achieve this youmobile phone is in constant communication with your nearestantenna.

If you move location, and your original antenna no longer hasenough reach to connect to your mobile, your phone willautomatically search for another one. The new antenna theninforms the system of your new location.

Conclusion: This article is by no means trying to undermine theachievements or the potential the technology has to offer.Instead, it is intended to provide an insight to the keyelements of the mobile phone technology which would otherwiseremain invisible to everyday users
