World's first handheld cellular phone call in public

In 1973, when Motorola installed a base station to handle the first public demonstration of a phone call via the mobile network, the company is trying to persuade the Federal Communications Commission to allocate frequency space to private companies for use in new mobile technology . After some initial testing in Washington for the FCC, Cooper and Motorola took the phone technology to New York to prove to journalists and the public. On April 3, 1973, standing on Sixth Avenue in New York near New York Hotel Hilton, Cooper made a phone call from an original hand Dyna-Tac phone before attending a press conference on the hotel. The phone is Cooper with the base station on top of Burlington House (now the Alliance Capital Building) across from the hotel and the AT & T's telephone system, land-line. As journalists and passers-by saw that the number dialed and held the phone to his ear. The first call, placed by Dr. Joel S. Engel, head of research at Bell Labs, began a fundamental technology and communications market shift towards making phone calls to a person, not a place. This is the first phone weighed about £ 2.5 (1,1 kg). It was the product of Cooper's vision for personal wireless mobile telephone communications, distinct from mobile phones car. Cooper said that Captain Kirk monitor the Communicator of the television show Star Trek inspired him to develop the handheld mobile phone. 

After the demonstration of prototype mobile phone to reporters, Cooper has allowed some of the journalists to make phone calls to anyone they choose to demonstrate that the mobile phone could serve as a flexible portion of the telephone network. 

Cooper, considered the inventor of the first handheld mobile phone and the first person to make a phone call to the public in a mobile phone. Cooper and engineers who worked for him, and Mitchell is the name for the patent "telephone system Radio" filed on October 17, 1973.

About the inventor of Mobile Phones

Inventor of Mobile Phones

Martin Cooper (born December 26, 1928 in Chicago, Illinois, USA) is a former American vice president of Motorola and director of the section in the 1970's led theteam that developed a handheld mobile phone (as distinct from the car phone). Cooperis the CEO and founder of ArrayComm, a company operating in the investigation ofsmart antenna technology and improving wireless networks, and corporate director ofResearch and Development for Motorola.

After World War II, Cooper, son of Ukrainian immigrants, he left the Navy and began working at Teletype, a subsidiary of Western Electric. In 1950, he received his degree in Electrical Engineering from Illinois Institute of Technology (IIT). In 1954, he was hired by Motorola, and attended classes and studied at night. He went on to earn a master's degree in electrical engineering from IIT in 1957, and taught evening classes at the university.In 1960, John F. Mitchell, who also received a degree in electrical engineering (1950) from IIT, became chief engineer of the mobile communications projects of Motorola.Cooper noted Mitchell. In the 1960's, the Cooper role in turning pagers from a technology used in buildings and only one which spread across cities. Cooper helped fix a flaw in quartz crystals Motorola made radios. This encouraged the company to mass-produce the first crystals used in watches. Cooper worked on developing portable products, including the first portable radio to the Police in the Chicago police department in 1967.In early 1970, Mitchell Cooper put in charge of part of car phone, where he was chief cell research Motorola. Cooper envisioned mobile phones to be used not only in a car, but also small and light enough to be portable. Thanks to years of research and development in mobile products directed by Cooper and new technologies across the company, when the pressure was on, it took only 90 days in 1973 to create the first portable cellular phone original 800 MHz.

What is a Mobile Phone and who made it first??

1. What is a Mobile Phone?

Mobile phones, mobile phones or mobile electronic devices that are used to make mobile phones in a wide geographic area served by the cells of many people who use mobile phones to do it. In contrast, wireless phones will be used in a range of one base station, private, such as your home or office. 

Mobile phones can make and receive to and from the public telephone network, including mobile phones and other fixed around the world. Does this by connecting to the mobile network to mobile network operators. 

In addition to telephone, mobile phone also supports a variety of advanced services such as messaging, MMS, E - mail, internet short-range wireless communications (infrared, Bluetooth), program. business, gaming and photography. Mobile phones are increasingly offering the ability to use computers generally referred to as smartphones. 

The first mobile phone demonstrated by Dr. Martin Cooper of Motorola in 1973, using weight 2 kg. [1] In 1983 8000x DynaTAC was the first time will be available.commercialization in twenty years 1990-2010, global mobile data sources, up from 12.4 million, more than 4.6 billion surpassed the country's economy is developing and to the bottom of the economic pyramid.

2. History of Mobile Phone..

Radiophones has a long history and diverse back to Reginald Fessenden invention and shore-to-ship demonstration of radio telephony, through the Second World War with military use of radio telephony links and civil services in the 1950s. Call the first mobile phone from a car and took place in St. Louis, Missouri, United States of America June 17, 1946, using Bell System mobile phone service, but this system is not practical from what is today the mobile phone. Weight equipment, £ 80 (36 kg), and AT & T service, essentially the party line and wide, cost $ 30 per month (equivalent to $ 337.33 today), in addition to the $ 0.30 to $ 0.40 per local call, which is equivalent to $ 3.37 today to $ 4.5 . In 1956, launched the world's first car phone automatically part system, mobile system A (MTA), in Sweden. The MTA is composed of mobile vacuum tubes and carriers, and the weight of 40 kilograms. In 1962, called version more recent Mobile System B (short-term, was launched by the phone button is pressed, which used transistors in order to strengthen the capacity of the phone connected and improve operational reliability, which reduces the weight of the device to 10 kg. In 1971, The Release million, and open to different brands of equipment and access to commercial success.
The mobile phone is not early The Martin Cooper, a researcher at Motorola, Inc. and the executive to be the inventor of the first practical mobile phone for handheld use in a vehicle is, after a long race against Bell Labs for the first mobile phones. Using the modern, mobile phones if somewhat heavy, Cooper made the first contact on a mobile phone by hand on April 3, 1973 at his rival, Dr. Joel S. Engel of Bell Labs. And launched the first commercial cellular network automation (and 1G) in Japan NTT in 1979, initially in the Tokyo metropolitan area. Within five years, has been expanding the network of NTT to cover all of Japan's population, and became the first network 1G country. In 1981, followed by the simultaneous launch of a mobile system for the north (or. T) in the phone, Denmark, Finland, Norway and Sweden.. Um. T was the first mobile network service is roaming. It was the first 1G network was launched in the United States and Chicago-based Ameritech in 1983, using the mobile phone Motorola DynaTAC. Then followed by several countries in the period from the early to mid-1980s, including Mexico and the United Kingdom and Canada. Has launched a "modern" first network technology on digital 2G (second generation) cellular technology by Radiolinja (now part of Elisa Group) in 1991 in Finland on the GSM standard, which also saw the introduction of competition in the mobile sector when he challenged the Radiolinja Finland Current Communications (now part of TeliaSonera) who ran the network is. T-1G.  In 2001, he was the first commercial launch of third generation 3G (third generation) again in Japan by NTT DoCoMo at the level of WCDMA. Implemented one of the newer technologies 3G high-speed Downlink Packet Access (HSDPA). Is the promotion of 3G (third generation) protocol for mobile telephony in the high-speed packet access (Hspa) family, also coined the 3.5G, 3G + or 3G Turbo, which allows networks based on Global System for Mobile Telecommunications (UMTS) to the top data transfer speeds and capacity.
