Information About The Mobile Phones
A mobile phone, also known as a cellular phone or cell phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN).
History of mobile phones
The first mobile phone call was made in 1973 by Martin Cooper, an engineer at Motorola. The phone weighed 2.4 pounds and had a talk time of only 30 minutes. In the early days of mobile phones, they were only used by businesses and government agencies. They were very expensive and had limited features.
In the 1980s, mobile phones began to become more affordable and available to the general public. They also started to have more features, such as text messaging and cameras. In the 1990s, mobile phones became even more popular, and they began to replace landline phones in many homes.
Today, mobile phones are an essential part of our lives. We use them to stay connected with friends and family, to get work done, and to entertain ourselves. There are billions of mobile phones in use around the world, and they continue to evolve with new features and capabilities.
