Problems solved by technology
However, there is a huge link loss when the millimeter wave signal passes through the building wall, resulting in the wireless millimeter wave signal basically losing the ability to pass through the wall, making it difficult to directly cover indoors
[0003] In order to solve the problem of millimeter-wave indoor coverage, the existing methods mostly use the feeder to introduce the millimeter-wave signal into the room, and then perform relay amplification; however, the coverage of this simple relay amplification is very limited
In order to further improve the coverage, on the basis of relay amplification, the radio frequency feeder can be extended to the room to achieve deep indoor coverage; however, the millimeter wave feeder is complex to lay, high in cost, large in loss and susceptible to electromagnetic interference

The present invention provides a photonic millimeter wave indoor coverage transmission method and system, comprising: receiving downlink wireless millimeter wave signals transmitted by outdoor base stations; converting the wireless millimeter wave signals into optically carried millimeter wave signals; The optical-carried millimeter-wave signal is sent indoors; the indoor optical-carried millimeter-wave signal is converted into a wireless millimeter-wave signal, and the downlink wireless millimeter-wave signal is transmitted. The embodiment of the present invention solves the problem that the millimeter wave signal is difficult to pass through the building wall by converting the wireless millimeter wave signal into an optically carried millimeter wave signal, and introducing the optically carried millimeter wave signal into the room based on a distributed optical fiber. The low-loss transmission advantage of the technology realizes the deep indoor coverage of millimeter waves.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to a photon millimeter wave indoor coverage transmission method and system. Background technique [0002] With the rapid development of mobile communication technology and the emergence of various broadband applications such as smart home and AR / VR, the demand for data traffic is growing explosively, and the spectrum resources in low-frequency bands are becoming increasingly scarce. The millimeter wave frequency band has the characteristics of abundant available spectrum resources, high data transmission rate and low delay, which can meet the user's demand for ultra-high data traffic. However, there is a huge link loss when the millimeter-wave signal passes through the building wall, which causes the wireless millimeter-wave signal to basically lose the ability to pass through the wall, making it difficult to directly cover indoors. [0003] In order to solve the pro...
