Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, are within the scope of the invention.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating a deployment method of an indoor distribution system according to a first embodiment of the present invention, the method including the following steps:
step 21: dividing a to-be-arranged area into at least two areas according to the network capacity requirement;
step 22: determining a deployment plan for each of the regions, the deployment plan for the regions comprising: a remote device matched to network capacity requirements of the area, the remote device comprising: an active radio frequency remote unit, a passive antenna or a repeater.
The deployment method provided by the embodiment of the invention can determine different deployment schemes according to different actual scenes, saves construction cost and can realize network fine management.
In the embodiment of the invention, each remote device has advantages and disadvantages.
The active radio frequency remote Unit (also referred to as RF Unit) is a remote source, and is configured to convert the digital signal or the analog intermediate frequency signal sent by the switching Unit into a radio frequency signal. Thus, the active radio frequency remote unit comprises: the radio frequency module, the frequency conversion module, the Analog-to-Digital Converter (ADC), the Digital-to-Analog Converter (DAC) and the Digital interface unit are the most expensive, but the coverage effect is good.
The passive antenna is a passive module, can only provide coverage, and has relatively low cost, but relatively insufficient coverage power and relatively general coverage effect.
The repeater is used for amplifying signals, and does not comprise: the frequency conversion module, the ADC module and the DAC module are relatively low in cost and have a good coverage effect, but the noise floor of the system is increased.
Therefore, the area to be networked is divided into a plurality of areas, and which remote equipment is deployed in each area is determined respectively, so that not only can the complete area to be networked have ideal signal coverage, but also the construction cost can be reduced.
In the embodiment of the present invention, in the deployment scheme of at least one of the areas, the remote device includes the passive antenna or the repeater.
That is to say, the remote device corresponding to at least one region includes a passive antenna or a repeater. Thus, the construction cost of the indoor distribution system is low.
In some preferred embodiments of the present invention, please refer to fig. 3, fig. 3 is a schematic structural diagram of an indoor distribution system deployed according to a deployment method of the present invention. The indoor distribution system 30 includes: a baseband unit 31, a switching unit 32 connected to the baseband unit 31, and a remote device 33 connected to the switching unit 32. The remote device 33 includes: the active radio frequency far-end unit 331 is externally connected with the active radio frequency far-end unit 331, the passive antenna 3312 and the repeater 3313.
Specifically, if the remote device in the deployment scheme of an area includes an active radio frequency remote unit, the active radio frequency remote unit may be directly externally connected to the switch unit, or the active radio frequency remote unit may be externally connected to the deployed active radio frequency remote unit, so that the deployment is more flexible and convenient.
If the remote device in the deployment scheme of another area includes a passive antenna, the passive antenna is externally connected to the active radio frequency remote unit, which has the following 4 advantages:
1) Easy to expand
The passive antenna externally connected with the active radio frequency remote unit has a broadband characteristic (namely, can support the full frequency band). Moreover, passive products (such as radio frequency feed cables, power dividers and passive antennas) supporting the frequency Band of 0.8-3.8GHz have been developed in the industry at present, the passive products naturally support the frequency bands of C-Band (C-Band) 100MHz and 2/3/4G, and new systems can be quickly compatible in the future. Therefore, if the active radio frequency remote unit needs to be upgraded to support a new frequency band/standard signal, only the active radio frequency remote unit needs to be replaced, and an external passive product does not need to be replaced.
Still taking fig. 3 as an example, the passive antenna 3312, rf feed cable 3314 and power divider 3315 are all external to the active rf remote unit 331 and are broadband in nature. Therefore, if the active remote unit 331 needs to be upgraded to support new band/mode signals, only the active remote unit 331 needs to be replaced, and the passive antenna 3312, the rf feed cable 3314, and the power divider 3315 do not need to be replaced.
2) Elastic expansion
The elastic expansion capability is shown in fig. 4. Before network capacity expansion, 4 active radio frequency remote units can be combined into 1 cell, and after the network capacity demand is increased, the 4 active radio frequency remote units realize 4 times of network capacity improvement through cell splitting.
3) Multiple input multiple output (nTnR)
The active radio frequency far-end unit of 5G network possesses 4T4R ability, and its external antenna is dual polarized antenna, possesses 2T2R ability. Therefore, the active radio frequency remote unit externally connected with the passive antenna has the capabilities of 4T4R and 2T2R at the same time. Active radio frequency remote units can be distributed in the area with large network capacity, and passive antennas can be distributed in the rest areas.
4) Low cost
The use amount of the active radio frequency far-end unit is reduced, the use amount of the passive antenna is increased, and the whole networking cost is reduced.
If the remote device in the deployment scheme of another region includes a repeater, the repeater is externally connected to the active radio frequency remote unit, and the following 2 advantages are provided:
1) Low cost
For the area which only needs to be covered and has low network capacity requirement, the repeater can be externally connected with the active radio frequency remote unit, namely the repeater is pulled to the coverage area through the radio frequency feeder cable, and then the repeater is used for covering. Because the loss of the long radio frequency cable is large, the coverage power is insufficient if a passive antenna is used; if an active radio frequency remote unit is used, the cost is high, and the flexibility is poor.
Still taking fig. 3 as an example, the repeater 3313 is externally connected to the active rf remote unit 331, which can ensure ideal signal coverage for areas with low network capacity requirements.
2) Easy to expand
With the increase of active radio frequency remote units, the repeater can simultaneously support multi-mode and multi-frequency, thereby being convenient for upgrading.
In the embodiment of the invention, the area to be networked is analyzed in detail, the area to be networked is divided into at least two areas according to the network capacity requirement, different deployment schemes can be determined aiming at different areas, the flexible combination of the active radio frequency remote unit, the passive antenna and/or the repeater can be realized, the communication requirement of the area to be networked can be met, and the construction cost is saved.
In some preferred embodiments of the present invention, the step of determining the deployment scenario for each of the regions comprises:
and determining the remote equipment matched with the network capacity requirement of the area according to the network capacity requirement of the area or the network capacity requirement of the area and the geographic information of the area.
In particular, it may be determined which remote devices are deployed in an area based on the network capacity requirements of the area. For example: the network distribution area is a shopping mall, the network capacity requirement of an underground parking lot of the shopping mall is low, and the passive antenna is used for covering; the network capacity requirements of shops and corridors are high, and active radio frequency remote units are used for covering.
It may also be determined which remote devices are deployed in an area based on the network capacity requirements of the area and the geographical information of the area. For example: the network capacity demand of the washrooms on each floor in the shopping mall is low, and the washrooms are shielded by more walls and are covered by the repeaters.
It is also necessary to determine how many remote devices need to be deployed, as well as which remote devices are deployed in the area.
Therefore, in some preferred embodiments of the present invention, the step of determining the deployment scenario for each of the areas comprises:
and determining the number of the remote devices deployed in the region according to the area of the region and the coverage area of the single remote device.
Specifically, the following can be calculated according to the calculation formula: the number of remote devices = area of region/coverage area of a single remote device, determining the number of remote devices deployed in the region.
For example: the area of a region is 200 square meters, it is determined that the remote device deployed in the region is an active radio frequency remote unit, and the coverage area of a single active radio frequency remote unit is 60 square meters, and it may be determined that 4 active radio frequency remote units need to be deployed in the region according to the above calculation formula.
In some preferred embodiments of the present invention, the step of dividing the area to be screened into at least two areas according to the network capacity requirement includes:
acquiring a map of the area to be networked, wherein the map comprises people flow information;
and determining the network capacity requirement according to the people flow information.
That is to say, the network capacity requirement can be determined according to the estimated pedestrian volume of the area to be networked and the density degree of the pedestrian volume, and then the area to be networked is divided.
Preferably, the at least two regions comprise: a first region, a second region, and a third region;
the people flow density of the first area is greater than a first threshold value;
the pedestrian flow density of the second area is less than or equal to the first threshold and greater than a second threshold;
the density of pedestrian volume in the third area is less than or equal to the second threshold;
wherein the first threshold is greater than the second threshold.
That is, according to the density of the flow of people, the area to be screened is divided into 3 areas: a first zone of highest (most dense) traffic density, a second zone of medium (medium) traffic density, and a third zone of lowest (least sparse) traffic density.
Preferably, the people flow information is a people flow heat prediction graph marked on a map.
Taking fig. 5 as an example, fig. 5 is a schematic diagram of a map of an area to be screened according to an embodiment of the present invention. The indoor electronic map of the existing area to be networked can be acquired, or the indoor electronic map of the area to be networked can be drawn. The map of the thermal budget of people flow can be marked on the electronic map according to historical experience or an existing indoor distribution (such as 2G/3G/4G/Bluetooth) network, as shown in FIG. 5. The higher the people flow density in the people flow heat estimation graph, the larger the network capacity requirement. Thus, the area to be screened is divided into a first area 51, a second area 52 and a third area 53.
Optionally, the people flow thermodynamic diagrams in the historical time period are averaged to obtain the people flow thermodynamic prediction diagram.
For example, an area to be screened is a market to be modified, people flow thermodynamic diagrams of the market over multiple days can be integrated, accumulated and averaged, and the averaged people flow thermodynamic diagram is obtained and used as a people flow thermodynamic prediction diagram.
Optionally, estimating by using a mathematical model according to the geographic information of the area to be networked to obtain a people flow heat estimation diagram.
I.e. according to the geographical features of the area to be screened, such as: and performing data modeling on the position of a stair, the position of a toilet, the position of a hot store and the like to obtain a people flow thermal estimation diagram.
Preferably, in the deployment scenario of the first area, the remote device is the active radio frequency remote unit;
in a deployment scheme of the second area, the remote device is the active radio frequency remote unit or the passive antenna;
in the deployment scheme of the third area, the remote device is the passive antenna or the repeater.
Still taking fig. 5 as an example, the first area 51 has dense pedestrian volume, and the active rf remote unit not only has strong coverage capability but also has high network capacity, so that deployment using the active rf remote unit is also convenient for future capacity expansion.
The second region 52 is of moderate traffic volume and may be deployed using active rf remote units or using passive antennas.
The third area 53 has a rare flow of people (e.g., few people or no people are present in the third area 53), and if the wiring is easy, the third area can be deployed by using a passive antenna, in which a plurality of passive antennas of the active rf remote units are disposed; if wiring is difficult, a repeater may be deployed in the third area 53.
In the embodiment, the area to be netted is divided into 3 areas; of course, the number of the regions may also be determined according to actual requirements, such as: the area to be netted is divided into 2 and 4 areas, which is more flexible and convenient, and the invention is not limited.
In the above embodiment, the area to be networked is divided into at least two areas according to the people flow information; of course, in some other embodiments of the present invention, the area to be networked may be divided into at least two areas according to the traffic information; or may be comprehensively divided according to the traffic information and the traffic information, and divide the area to be networked into at least two areas, which is not limited in the present invention.
