A mobile phone (also known as a wireless phone, cell phone, or cellular telephone) is a very small
portable radio telephone.The first mobile phone networks were created in the late 1970s in Japan. A
cell phone combines technologies, mainly telephone, radio, and computer. Cell phones work as two-
way radios. They send electromagnetic microwaves from base station to base station. The waves are
sent through antennas. This is called wireless communication.
There are different kinds of phones. A flip phone flips open, and is best for calling. A bar phone is
shaped like a candy bar, and the keys and screen are on one face. A slate phone is a phone that has
almost no buttons, and uses a touchscreen. Most smartphones are slates. A slider phone slides on
rails. It can slide out number keys or a mini keyboard, but some do both. A swivel spins on an axle.
Many 21st century mobile phones are smartphones. These phones can be used for email, browsing
the internet, playing music and games,and many other functions that computers can perform. This is
because mobile phones basically are small computers. Older phones also used computer technology,
but lacked many of the parts of a computer that were too big to fit into a phone. Modern phone
makers have been able to use smaller parts. Most smartphones are also GPS receivers and digital
cameras.
