What is the history of the mobile phone?

It seems that mobile phones have long been reserved for rich or companies that could afford to be a key employee too long from contact. Today they are a matter of course. However, in order to get to this point, the history of the mobile phone has evolved quite slowly. Instead of coming in a flash, the mobile phone came for a browsing.

Although some may laugh at this idea, the first person to achieve wireless communication by sending electronic signals was probably a man named Dr. Mahlon Loomis in 1865. He sent a telegraphic message 18 miles (29 km). While this performance was a monumental success that even earned Loomis recognition of the US Congress, it was still far from the voice communication that the mobile phone now offers. Although he was now an outdated rotary phone in his main condition, there were those who looked at wireless skills. In 1947, AT&T proposed frequencies were assigned to help with wireless communication.The Federal Communication Commission (FCC), perhaps really did not understand the severity of what was proposed, reduced the number of frequencies available to such an extent that only 23 interviews could take place at the same time in one place of service.

Yet, despite these limits, the concept of the mobile phone continued until Dr. Martin Cooper, who was the CEO of the Motorola Division, did not invent the first usable hand -held mobile phone in 1973. Some car phones were available before this point. This prototype eventually released a plan for millions of other mobile phones. For the first time four years later, the demand began to increase.

However, there was still a problem. Although the demand increased sharply, FCC still limited the width of the 1947 standard bands. Whenever there is a shortage and high demand, it makes things expensive. Cell phones were therefore not for the vast majority of people in priceAvailable, even in developed countries.

In 1987, FCC opened more frequencies in the 800 MHz band. FCC began to realize that the meaning of not only a mobile phone, but also a wireless phone. The regulations were relaxed for both. Although calm and mobile phones remained expensive, it was the beginning of price breaks that led to their explosion in popularity. Since then, several different standards have been invented to take advantage of the released regulations not only in the United States, but around the world.

Today, most places in the world have access to an analog service or digital service. Everyone has their own advantages. The digital service will also be divided into competing technologies in some areas of the world. These include multiple TIMESS (TDMA) divisions, code divisions of multiple access (CDMA) and global mobile communication system (GSM).
