Abstract
A portable communication used in a mobile communications network has a transceiver device for providing a first wireless communication link to the mobile communications network. It also has visual indicator adapted to emit a first visible light signal, within a first predetermined spectral range, for indicating a status of the first wireless communication link. The transceiver device also provides a second wireless communication link to equipment other than the mobile communications network. The visual indicator emits a second visible signal for indicating a status of the second wireless communication link. This second visible light signal is provided in a second spectral range, which is different from the first spectral range.
