The invention relates to a novel multi-network-integrated indoor
distribution system. The novel multi-network-integrated indoor
distribution system comprises an access unit, an extension unit and a remote end unit, wherein the access unit, the extension unit and the remote end unit transmit signals through digital optical fibers; the access unit can couple multiple downlink radio-frequency (RF) signals from RRUs (Radio Remote Units) of different systems, and the downlink RF signals are converted into
baseband digital signals after the downlink RF signals pass through a digital
processing unit; the access unit can receive downlink
baseband signals from BBUs (Building
Baseband Units) of different systems, and the downlink
baseband signals can be transmitted together with the baseband digital signals, which are received and processed by an RF
coupling port, after the downlink baseband signals pass through the digital
processing unit. The novel multi-network-integrated indoor
distribution system has the beneficial effects that indoor
signal coverage is realized by adopting information source access, digital
optical fiber transmission and remote coverage; and the access unit supports
signal access of multiple network types and supports
signal access of
multiple forms. The invention discloses a multi-network-type signal access and coverage
system, and repeated construction is avoided, so that the
system is energy-saving and environment-friendly; meanwhile, the
system supports the signal access of
multiple forms, so that
network construction is more flexible and convenient.
