Digital optical fiber remote multi-medium transmission household coverage system

Abstract

The invention relates to a digital optical fiber remote multi-medium transmission household coverage system. The system comprises a near-end unit, an extension unit and a far-end unit. The digital optical fiber remote multi-medium transmission household coverage system has relatively high integration degree through setting of the near-end unit, the extension unit and the far-end unit. Mobile network signals (2G, 3G and 4G) are remotely transmitted to an LAN signal household device (a switch) and an xPON signal household device (an OLT) by digital optical fibers; the mobile network signals, WLAN signals and XPON signals are combined and then are transmitted by original household optical fibers or 0.5 data communication cables. The original data functions of the original household optical fibers and the 0.5 data communication cables are not influenced. Moreover, the household coverage of wireless voices and data is realized. According to the system, the construction difficulty that the traditional indoor distributed system is long in construction time and difficult in property coordination is overcome; the mobile network signals are imported into the house for coverage by the original household optical fibers and 0.5 data communication cables; the difficulty of ping-pong effect and pilot pollution existing in the indoor network signals is solved without rewiring; and the perceptibility of a user is improved.

Description

technical field [0001] The invention belongs to the technical field of wireless communication equipment, and in particular relates to a digital optical fiber remote multi-media transmission user coverage system. Background technique [0002] Existing communities, hotels, and guesthouses all have broadband signals, and CAT5 lines or optical fibers are generally used to implement WLAN signals and xPON signals to enter the home to achieve home coverage; while the antennas of traditional indoor distribution systems are all at the door of the house, and indoor terminals receive The mobile network signals (2G, 3G, 4G) sent by the indoor distribution system pass through multiple walls, and the signal attenuation is serious, resulting in the same field strength between the indoor signal and the mobile network signal from other outdoor macro stations, resulting in ping-pong effect and induced Frequency pollution seriously affects user perception.
