History of Mobile Phone

History of Cell Phone (1973 to 2011)

April 3, 2003 marked the 30th anniversary of the first public telephone call placed on a portable cellular phone. Martin Cooper ( now chairman, CEO, and co-founder of ArrayComm Inc) placed that call on April 3, 1973, while general manager of Motorola's Communications Systems Division. It was the incarnation of his vision for personal wireless communications, distinct from cellular car phones. That first call, placed to Cooper's rival at AT&T's Bell Labs from the streets of New York City, caused a fundamental technology and communications market shift toward the person and away from the place.


"People want to talk to other people - not a house, or an office, or a car. Given a choice, people will demand the freedom to communicate wherever they are, unfettered by the infamous copper wire. It is that freedom we sought to vividly demonstrate in 1973," said Martin Cooper.
Martin Cooperadded, "As I walked down the street while talking on the phone, sophisticated New Yorkers gaped at the sight of someone actually moving around while making a phone call. Remember that in 1973, there weren't cordless telephones, let alone cellular phones. I made numerous calls, including one where I crossed the street while talking to a New York radio reporter - probably one of the more dangerous things I have ever done in my life."

Following the April 3, 1973, public demonstration, using a "brick"-like 30-ounce phone, Cooper started the 10-year process of bringing the portable cell phone to market. Motorola introduced the 16-ounce "DynaTAC" phone into commercial service in 1983, with each phone costing the consumer $3,500. It took seven additional years before there were a million subscribers in the United States. Today, there are more cellular subscribers than wireline phone subscribers in the world, with mobile phones weighing as little as 3 ounces.
