Embodiment 1

[0041] Please refer to Figure 5 , Embodiment 1 of the present invention is:

[0042] The signaling link of the present invention includes uplink and downlink, such as Figure 5 As shown, the downlink is: the downlink of the near-end unit is used to pass the downlink radio frequency signal of the LTE dual-channel base station or the LTE dual-channel base station remote system through the duplexer 1 (ie the first duplexer), the duplexer Device 2 (i.e. the second duplexer) respectively enters the near-end down-conversion circuit 1 and the near-end down-conversion circuit 2, and the near-end down-conversion circuit 1 and the near-end down-conversion circuit 2 respectively down-convert the downlink radio frequency signal to LTE dual-channel The downlink intermediate frequency signal, the LTE dual channel downlink intermediate frequency signal enters the ADC analog-to-digital conversion circuit to be converted into an LTE dual channel downlink digital signal, and the LTE dual chan...

Abstract

The invention relates to an LTE two-channel digital optical fiber remote home-entry coverage system. The LTE two-channel digital optical fiber remote home-entry coverage system comprises a near end unit, an extension unit, and a far end unit. The LTE two-channel digital optical fiber remote home-entry coverage system implements digital optical fiber remote of the LTE two-channel signals through the near end unit, solves the problem that the LTE signals and xPON signals are not in the same site location, packages the LTE two-channel signals and the xPON signals through the extension unit and the far end unit, utilizes the existing xPON home-entry optical fiber to perform home-entry coverage, and meanwhile realizes the home-entry coverage of the LTE two-channel signals without influence on the xPON signals. The coverage system overcomes the problems that the conventional indoor distribution system is long in construction period and difficult in property coordination; the LTE two-channel signals cover the house through the existing xPON home-entry optical fiber, so as to solve the problems of the indoor weak coverage, ping-pong effect, the pilot frequency pollution and the like of the LTE indoor network signals, and increase the user experience for users.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to an LTE dual-channel digital optical fiber remote home coverage system. Background technique [0002] With the rapid development of optical fiber technology, communication operators have also adopted the strategy of "light into copper and back out" in communication equipment. Existing communities, hotels, and guesthouses have broadband signals, and have basically adopted FTTH to realize xPON signal home coverage; the country is promoting "Broadband China", and the use of FTTH to realize xPON signal home coverage will be promoted on a large scale. However, the traditional indoor distribution system does not have home coverage, and the antennas are all at the door of the house. The LTE dual-channel signal is severely attenuated when passing through the wall, resulting in the same field strength between the indoor signal and the external signal, resulting in ping-pong ...
