Specific embodiment
To make the technical problem to be solved in the present invention, technical scheme and advantage clearer, below in conjunction with attached
Figure and specific embodiment are described in detail.
There is coverage hole in the present invention, cause indoor user to fill for indoor covering system in the prior art
Divide and receive indoor moving business so that network resources for wireless communication utilization rate is low, while being made troubles to user
Problem, there is provided a kind of indoor covering system, be laid on outdoor by by feeder cable, antenna is fixed on feedback
On line cable so that wireless network forms good covering indoors, indoor user can absorb it is more if
Business, improves the utilization rate of Wi-Fi resource.
As shown in figure 4, the embodiment of the present invention provides a kind of indoor covering system, including：Baseband processing unit
BBU, radio frequency remoto module RRU, power splitter, feeder cable and antenna；Wherein, the BBU passes through
Optical fiber is connected with the RRU；The input port of the power splitter is connected with the RRU, the work(point
The output port of device is connected with the feeder cable；The feeder cable is laid on outdoor, laminating building
Exterior wall is connected up；The antenna is fixed on feeder cable.
Need exist for explanation, the transmitting procedure of signal in indoor covering system：Signal source is passed by optical fiber
BBU is sent to, signal is sent to RRU after Base-Band Processing in BBU by optical fiber, through RRU by base
After band signal is converted into radiofrequency signal, branch is carried out to radiofrequency signal by power splitter, passed by feeder cable
Being sent to each antenna carries out in-door covering.
Here, feeder cable is laid on outdoor, and the exterior wall of building of fitting lays, in this way, feeder cable
Need not enter in the building body of building, reduce difficulty of construction, easily be linked up with owner and constructed.
Specifically, the wire laying mode of the feeder cable is laterally wiring or longitudinal direction wiring.
Here, the wire laying mode of feeder cable is mainly position, the knot of building building body in view of RRU
The main activities region of structure, indoor coverage areas and indoor user so that effective area of coverage of antenna can receive
More mobile services.It should be noted that the main activities region of indoor user is primarily referred to as user's treatment
The main activities region of mobile service.
Specifically, the antenna is platy directional antenna, the platy directional antenna is solid by integrated coupling bar
Due on the feeder cable.
As shown in figure 5, the antenna of the embodiment of the present invention and the direct-coupled structural representation of feeder cable.Under
Face illustrates the reality that platy directional antenna is fixed on the feeder cable by integrated coupling bar with reference to the figure
Apply process.
First, an aperture is opened on feeder cable, it is exposed cable core, i.e., being looked in from aperture can
See cable core.
Afterwards, in the integrated coupling bar in port of platy directional antenna.
Here it is possible to adjust the size of coupling bar to realize the degree of coupling of unlike signal.
Finally, direct-coupling energy will be contacted with internal layer cable core in the aperture of coupling bar insertion feeder cable.
It should be noted that, using the coupling scheme of feeder cable direct-coupling antenna, existing interior can be saved
It is not required to cut feeder line electricity in covering system substantial amounts of signal coupler required when connecting up, and wiring implementation process
Cable connection cable joint, as shown in figure 3, so that installing simple, saving is a large amount of to be produced and building time；
While the device because reducing cable connector, coupler equal loss's electric signal, significantly improves radio communication
Network power utilization rate, and reduce the fault rate of antenna-feedback system.
Specifically, the position of platy directional antenna described in the embodiment of the present invention is arranged at the every of the building
One layer, and close to the main activities region of indoor user, the main activities region is that indoor user is pre- one
Region of the interior use Wireless network frequency of fixing time more than a preset value.
Here, Wireless network frequency specifically refers to the frequency that user processes mobile service, that is, user's treatment
The number of times of mobile service, when the number of times that indoor user processes mobile service within a scheduled time is preset more than one
During value, then the zone of action of user treatment mobile service is main activities region.For example, in a star
In phase, when the number of times of indoor user treatment mobile service is more than preset value 25, then the user processes mobile industry
The zone of action of business is main zone of action.For residential building building, bedroom, parlor are generally referred to.
Specifically, the signal radiation direction of platy directional antenna described in the embodiment of the present invention is towards indoor user
The main activities region.
Here, the signal radiation direction of platy directional antenna is towards the main activities region of indoor user,
So that the effective coverage range of cordless communication network is bigger, covering that can be good to indoor formation.
As shown in fig. 6, be the schematic diagram of antenna footprint in the indoor covering system of the embodiment of the present invention,
The application of the indoor covering system of the embodiment of the present invention is illustrated by taking the figure as an example below.
This figure is the structured flowchart of the house at typical terraced three family, is covered using the interior of the embodiment of the present invention
Convering system, outdoor is laid on by feeder cable, and residence outer wall body wiring of fitting, wire laying mode is more flexible,
By the way of transverse direction and longitudinal direction combination.
Antenna is fixed on feeder cable, and its placement is placed on by the analysis to indoor arrangement situation, cloth
The main region of mobile service is processed near indoor user main activities region, i.e. user.Antenna master in the figure
It is laid at the exterior wall in parlor or bedroom near the position of window, the signal radiation direction faced chamber of antenna
The main activities region of interior user.
In this way, under the indoor covering system, the main activities region of indoor user has obtained sufficient covering,
And the placement of antenna also causes that indoor user is located in best signal receiving point, improves wireless network
The utilization rate of resource so that indoor user can absorb more traffics, improve Consumer's Experience.
The above is the preferred embodiment of the present invention, it is noted that for the common skill of the art
For art personnel, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made,
These improvements and modifications also should be regarded as protection scope of the present invention.
