Mobile telephone
Mobile telephone. Mobile or cellular telephones use low-power radio signals to transmit to an antenna in the users local area, or cell. The antenna is linked via telephone lines to an exchange devoted to mobile telephone calls. The exchange will connect the call to other mobile telephones, or if necessary to a normal telephone exchange if the call is not for another mobile telephone. If the mobile telephone moves out of its cell during a call, the exchange will automat- ically connect via the antenna of the new host cell. It does this by monitoring the change in the power of the radio signal between the mobile telephone and the antennae of adjacent cells

EDITORS COMMENTS
This print from Science Photo Library captures the essence of modern communication technology - a mobile telephone. The image showcases the sleek design and compactness of this device that has revolutionized our lives. Mobile or cellular telephones have become an integral part of our daily routines, enabling us to stay connected with loved ones and access information at our fingertips. The photograph beautifully illustrates how these devices use low-power radio signals to transmit data to an antenna in the user's local area, also known as a cell. This antenna is then linked through telephone lines to a dedicated exchange for mobile telephone calls. Whether connecting with other mobile phones or traditional landlines, this exchange ensures seamless communication. One remarkable feature highlighted in the image is the ability of mobile phones to adapt during calls when moving between different cells. As we move around, the exchange automatically connects via new host cells' antennas by monitoring changes in radio signal power between the phone and adjacent cells' antennae. This still life composition not only showcases technological advancements but also serves as a reminder of how far we have come in terms of communication capabilities. It symbolizes connectivity, convenience, and progress all within one frame.
