History of Cell Phones
Finally there was a breakthrough in 1865 by Dr. Mahlon Loomis, a Virginia dentist and scientist. He managed to develop a method of communication through the earth"s atmosphere with an electrical conductor. Wondering what was his apparatus for conduction? Two kites connected to the ground on two separate mountains with the help of copper screens and wires. The U.S congress awarded him a grant of USD 50,000 for his electrifying discovery. Today, we transmit radio waves through large towers over our sky scrappers and mountains to help send our cell phone signals.Then about 50 decades later in 1921, the Police Department on Detroit, Michigan took a step into the world of technological advancement. They installed mobile radios of around 2MHz in their squad cars. But, they encountered overcrowding on the channels and terrible interference with their radio system. Today, we still suffer from bad signals and network congestion on our cell phones.
The US Congress noting the advancement in the technology of radio transmit ion, formed the Federal Communications Commission in 1934. What did this commission do? Well, they monitored the radio frequencies and decided who should be able to use these frequencies. They also reserved certain frequencies, only for the use of the government.
The 1940"s saw a radios being operated at 30 to 40 MHz and it became a common feature of the police department. Many affluent people could also boast of a radio. Soon, certain companies and organizations managed to forecast a gold mine and invested in radios. This gold mine has proved to be a path breaking investment of many multi-billion dollar companies today with the cell phone boom.
Another one of a path defying service was established in 1945. St, Louis, Mississippi witnesses establishment of the first mobile-radio-telephone service. There were six channels that added up to 150 MHz. By 1956, America got to choose an option of real car phones. These were bulky and big phones and needed a personal radio operator to switch calls.
