초록 ▼

A communication system in which many terminals located in a large room are connected to a host via a plurality of satellites. Data are exchanged between terminals and satellites by infrared signals. All satellites are connected to the host by a common bus arrangement comprising a data line (13) and a synchronization line (15). Each satellite generates a synchronized carrier and modulates it by the downlink data received from the host in a modulator (17). Each terminal may receive overlapping signals from several satellites without disturbance. Uplink data transmitted from any terminal are stored as packet in a buffer (55) of one or more satellites so that they can be transferred to the host subsequently via the bus arrangement. Each satellite has means (63) for comparing any transferred uplink packet to a packet still stored in its buffer so that any packet is transferred only once to the host and doubly stored packets are eliminated.

대표청구항 ▼

A communication system in which data are transferred between terminal stations and satellite stations by infrared signals, characterized in that for covering an extended area, a plurality of satellite stations (S1-S8) each with infrared transmitting means (17, 19) operating at a common carrier frequency are provided, the radiation fields of said transmitting means at least partially overlapping, and that common electrical link means (13, 15) are provided for transferring to all said satellite stations data signals (13) which are to be distributed to all said terminal stations simultaneously, and for further transferring a common timing signal (15) to all said satellite stations for synchronizing the carrier signals in said transmitting means, and that each terminal station within said extended area is provided with means for selectively accepting only one set of the simultaneously distributed data signals in any time period even if said terminal receives the infrared signals radiated by two or more satellite stations during said time period.
