Origination of Mobile Phones
-
The very first mobile phone call was made in 1973 by Martin Cooper, who was a manager at Motorola. Cooper said about mobile phones, "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." The phone Cooper used was as big as a brick and weighed more than 30 ounces. Today, mobile phones can weigh as little as 3 ounces and most easily fit into small pockets.
Coverage of Mobile Phones
-
Mobile phones can be used almost anywhere in the world, although the common cell phone technology is just one form of mobile phone. In some places, satellite phones are needed to reach out to the rest of the world. In 2009, there were at least 22 major mobile phone carriers serving the major countries of the world, and hundreds of others were trying to expand coverage to the far reaches of the globe.

Restrictions of Mobile Phones
-
There are a few places where mobile phone use is either illegal or highly frowned upon. Some major sporting events forbid the use of mobile phones on the premises. More often then not, those restrictions are applied at professional golfing and tennis events, where silence is often needed during competition. Some schools restrict the use of mobile phones by students, either in classrooms or during school hours.
Also, most commercial flights ban the use of mobile phones especially during the take off and the landing portion of the trip.
California, Connecticut, New Jersey, New York, Oregon, Washington, District of Columbia and the Virgin Islands all prohibit the use of mobile phones while driving, a practice some say is as dangerous as drunken driving.
Health Risks of Mobile Phones
-
There has been a long debate as to whether extended use of mobile phones over long periods of time can contribute to cancer. A mobile phone emits low levels of radiation, and some scientists believe that can cause damage over time to the tissues in the head.
Mobile Phone Technologies
-
Every year there are new and exciting developments in the world of the mobile phone. For example, VoIP (Voice Over Internet Protocol) uses the Internet to network some mobile phones, rather than cellular networks. Satellite phones have been around for a little bit longer, and are especially important for communication from remote locations or from places where cellular and Internet communication has been disrupted by disasters or war. The military, for example, continues to enhance satellite phone technology in order to be able to communicate more effectively in remote or war-torn areas.
