Mobile telephone. Mobile or cellular telephone with part of its outer casing removed to show its inner circuitry. Mobile telephones use low-power radio signals to transmit to an antenna in the user's local area,or cell. The call will then be connected to another mobile telephone,or,if necessary,a conventional telephone exchange. Mobile telephones can be used anywhere as long as the radio signal to the antenna is strong enough | |
