TELEPHONE



In 1876 the Scotish man Alexander Graham Bell invented telephone. Elisha Grey and Thomas Alva Edison helped him to improve the sound quality. 11th 2005 U.SA. Congress approved that the real inventor was Antonio Meucci, who invented telephone in 1871. What happened was he had not economic resources to patent it. Anyway none of them could never imagine how this invent would evolve.

· FIXED PHONE :

Through fixed phone you can do calls to any phone number around the world. The most of homes have this sort of phone and telephone companies fix cheap prizes to their clients. For example in Spain you can do calls to another fixed numbers phone completely free as time as you want.

· MULTY FIXED PHONE :

Many phones connected by the same number. This is very useful in offices, universities, hospitals, … When you call to your phone company you have to wait long time since there are many people being attended by many operators. Even there is a machine which orders to you push bottoms or tell any words like your name, surname or your phone number. I personally hate talking to machines. They misunderstand me and I became nervous.

· ADSL OR HDSL :

You can have Internet through your fixed phone. The most of phone companies offer this service and the majority of people use it. At the beginning when you received a call, your Internet connection stopped. You had to connect again. And you just could use Internet since 6:00 P.M until 8:00 A:M. Nowdays you can use it the whole day and receive calls during your connection.

· MOBIL PHONE :

This was the real revolution. At first having a mobil phone was a luxury because they are so expensive. I can remember my first mobil phone. Something like a brick with bottoms and just three melodies. But I was happy with him. Sending SMS, attending calls, etc … I had to charge it everyday and I always was worried about its battery. Nowdays there are mobile phones very little and with a lot of stuff. For example you can listen to radio or your favorite MP3 music. You can take pictures or recording videos and send them through your mobile phone to another user. You can do videocalls just like Messenger or Skype. You can use Internet in your mobile phone or playing games. Another mobile phones have GPS services so you can look for any adress if you are lost.

Some health experts say there are many young people adicted to mobile phone. They spend loads of money in it and can not live without their phone. Some teachers tell many of their pupils make mistakes writing because of typical SMS language.

The major manufacturers are Nokia, Samsung and Erison. They sell most mobile phones in whole wide world. Mobile Phone Industry earn millions euros each year. They employ a lot of people in their factories. Telephone Companies earn loads of money too. Some people are upset with them because sometimes these companies offer interesting products and after people realise that have been deceived.

Anyway if Alexander Graham Bell, or Antonio Meucci could see how are the present phones, how work Mobile Companies and how many phones are made each day I am sure that they could not believe it . This consumer society is get used to buy a new mobile phone each year. They throw their previous mobile phone despite it works and they buy a new one, just because is a little bit better than the other. What should we do? Could we stop using mobile phones? Could we use only fixed phone or telephone box, just like in the past? If we could, we would not need mobile phone anymore. And we would not collaborate to enrich them with our money. The question is: could we live without mobile phones?
