Mobile phone

A mobile phone or cell phone is an electronic telecommunications device with the same basic capability as a conventional fixed-line telephone, but which is also entirely portable and is not required to be connected with a wire to the telephone network.

Most current mobile phones connect instead to the network using a wireless radio wave transmission technology (the exception is satellite phones).
