Mobile phone - Facts, Information, and Encyclopedia Reference article |
 | | A mobile phone, also known as a cellphone, mobile, or handphone, 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. |
 | | Mobile phones are also distinct from cordless telephones, which generally operate only within a limited range of a specific base station. |
 | | Professional mobile radio systems are very similar to cellphone systems and attempts have even been made to use TETRA, the international digital PMR standard, to implement public mobile networks, but normally PMR systems are sufficiently separate from the phone network to not really be considered phones but rather radios. |
