We can not imagine our life without the telephone. This is the first thing we take in our hands in the morning, very often use it during the day and, to be honest, the last thing we see before going to bed. News, communication, entertainment; everything is here.

A telephone was patented in the USA in 1876 by Alexander Bell. A handset was used both to receive and send peoples' messages. A bell was invented by Mr Watson, Mr Bell's colleague, later in 1878. The distance of operation of this line didn't exceed 500 meters. For a very long time, A. Bell was believed to be the inventor of the telephone. However, in 2002 the Congress of the USA credited Antonio Meucci with the right of the invention of the telephone. The thing is that Antonio had published an article about the telephone in an Italian newspaper 17 years earlier than A. Bell made his great invention. He failed to patent it because of financial problems.

The first telephones were without a direct communication line. That means that manual telephone stations could be used only with the help of operators. Only at the beginning of the 1920s, the possibility of direct connection appeared, and the disk phones were produced and used.

Nowadays cell phones or mobile phones are common because they are very convenient and quite cheap. The coverage zone is now wide and stable, allowing to make phone calls and send messages almost from everywhere. The whole cover zone is divided into "cells". The main idea of cell communication is based on the principle of honeycomb* in a beehive**. There are base stations and the coverage zone of each in ideal conditions looks like a circle. But because of the buildings, the shape is distorted and looks like a hexagon. The coverage zones of each base station slightly overlap each other providing a stable signal even when the user moves from one zone to another.

Communication is a very important thing in our life. The evidence of that we might find in ancient times, when not having a phone people communicated using a whistle or gong. Now we have plenty of opportunities and devices to meet all our needs.
