Abstract
In the present telecommunication system, a wired network receives a plurality of electrical signals, such as voice signals and transmits them. A first communication device is connected to the wired network. The first communication device includes means for receiving the plurality of electrical signals, a first storage means for storing the plurality of electrical signals, a first playback means for retrieving a portion of the stored plurality of electrical signals, and a first control means for controlling the first playback means to transmit the retrieved portion of electrical signals. The portion of the stored plurality of electrical signals which are retrieved are then placed onto a wireless network which is in communication with a plurality of portable units. Each of the portable units has capability of communicating with the wireless network for receiving the electrical signals therefrom. Finally, the first communication unit causes the stored plurality of electrical signals stored on the first communication unit to be transmitted to a different one of the plurality of portable units.
