ABSTRACT:
A wire/wireless communication system includes two units for wire/wireless communication of information using a telephone network between two locations which are far away from each other. One of the two units is a data transmitting unit, such as a computer terminal, which is positioned at a first location and the other is a data receiving unit. To the units, infrared transceivers are coupled to transmit information as infrared radiation and receive the infrared radiation. Also, to the data transmitting and receiving units, telephones are connected. These telephones are interconnected by the telephone network therebetween and are respectively connected to transceivers. Wireless communication between the computer terminal of the data transmitting unit and the telephone which are positioned at the first location may be accomplished by the transceivers respectively coupled to them. The electrical signal corresponding to the information from the computer terminal is supplied through the telephone network to the telephone which is positioned adjacent to the computer terminal at the second location.
