HYBRID SYSTEM FOR DISTRIBUTING BROADBAND WIRELESS SIGNALS INDOORS

摘要

The invention relates to a system (100, 200) for distributing broadband wireless signals indoors, comprising: a radio access node (101, 201) connected to a telecommunications access network through an access interface (107, 207), wherein said radio access node comprises a broadband signal transmission/reception module configured to transmit and receive VHF/UHF DVB-T broadband wireless signals through a broadband radio interface; and at least one piece of client equipment (102, 202) comprising a broadband signal transmission/reception module configured to transmit and receive VHF/UHF DVB-T broadband wireless signals through a broadband radio interface in the 5 GHz free band, wherein said 5 GHz free band is the one specified in the ETSI EN 301 893 standard. The system further comprises: at least one optical device (105, 205, 300) configured to: receive broadband signals from said radio access node (101, 201), select at least one broadband signal from said radio access node (101, 201), convert said broadband signal into an optical signal and transmit said optical signal through a link over plastic optical fiber (108, 208); and at least one transmitting device (109, 209, 600) configured to: receive and detect an optical signal from said at least one optical device (105, 205, 300) through said link over plastic optical fiber (108, 208), convert said optical signal into a DVB-T signal in the 5 GHz free band and transmit it through a broadband radio interface in the 5 GHz free band.
