Technical Field
The present invention relates to the field of communications, and in particular, to a method and an apparatus for covering a wireless frequency conversion hotspot, an electronic device, and a readable storage medium.
Background
Currently, 5G base stations are deployed in a large number, but these base stations are mainly used outdoors, and indoor 5G network coverage just begins. But 5G flow mainly takes place indoorly, a large amount of indoor distribution systems have been built in the 4G era, the overwhelming majority of current indoor distribution systems all are traditional DAS system, face the smallpox and have covered, distribution systems hides inside the smallpox, the construction needs to be simple relatively can better faster realization 5G reform transform, current distribution systems has one way simultaneously, double-circuit feeder, only can realize single current, double-current cover effect, how simple and convenient construction, provide the cover effect of more velocity of flow, can regard as the hot spot simultaneously again, make things convenient for some groups, enterprise customer or non-5G terminal customer uses high-quality 5G network, it is the urgent problem that needs to solve to step into the 5G era.
At present, the indoor hot spots have the following main schemes and corresponding problems:
simple combiner mainly adopts two channel indoor equipment directly to feed in current passive DAS system, can realize the coverage fast, nevertheless because traditional DAS distributed system is mostly single-channel scene, this kind of mode can only provide the 5G signal of single current, brings the network rate of about 300M at most, and user experience effect is not good.
The 5G wired frequency shift scheme needs to feed direct current in a power divider, a coupler, an antenna and a feeder line of the existing distribution system, the scheme needs to comprehensively examine the existing distribution system, once passive devices cannot be comprehensively examined, over-current short circuit of the distribution system is likely to be caused, the breakdown of frequency shift near-end equipment is caused, and the defects of difficulty in implementing grounding, potential safety hazard, high property coordination difficulty, more replaced devices and the like are overcome.
The CPE hot spot provides service by curing the flow rate at the device itself, with limited coverage and no ability to provide a wide range of service.
The WIFI hotspot can provide service only by deploying a set of equipment independently, the mutual interference degree between the wireless access points is higher, and the cell interference processing capability of the WIFI hotspot is weaker than that of the wireless access points.
And directly taking the 5G original frequency point as a hot spot. Because the 5G frequency is too high, the fading of the wireless space of the base station signal is too fast, and the coverage distance is small, if the 5G WIFI hotspot is deployed according to the 4G mode, the effect will be very undesirable, the quality of the base station signal received by the 5G WIFI hotspot is poor, the WIFI hotspot rate is also relatively low, and the improvement is not great compared with the 4G WIFI hotspot rate.
In summary, the indoor distribution system is urgently needed to realize low cost, fast and convenient operation, and high quality, so that non-5G terminal clients can enjoy 5G network services under the condition of providing high speed, and meanwhile differentiated services of local clients and enterprise clients are realized.
