In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the invention, are intended for purposes of illustration only and are not intended to limit the scope of the invention.
Example one
As shown in fig. 1, the present embodiment provides a method for arranging a high-density WIFI system, where the high-density WIFI system includes a routing and control device 1, a POE switch 2, a wireless AP3, and an AP load 4; the routing and control equipment is connected with the POE switch, the POE switch is connected with the wireless AP, and the wireless AP is wirelessly connected with the AP load; the method comprises the following steps of,
s1, calculating the required number of the wireless APs, and acquiring the number of channels;
s2, comparing the magnitude relation between the required quantity of the wireless APs and the quantity of the channels, and when the required quantity of the wireless APs is less than or equal to the quantity of the channels, arranging the required quantity of the wireless APs according to different channels adopted among all the wireless APs; if the required number of the wireless APs is larger than the channel number, arranging the required number of the wireless APs according to the same channel adopted among the wireless APs at intervals;
and S3, verifying the edge effect of the wireless AP arrangement according to the actual arrangement condition of the wireless AP.
In this embodiment, in step S2, when the required number of wireless APs > the channel number, the channels need to be multiplexed, and the distance between the adjacent co-channel wireless APs is ensured to be far enough, and the distance is at least greater than 20 meters by using the general AP arrangement.
In this embodiment, when the channel needs to be multiplexed and the space is small and the distance between the wireless APs needing the same channel is less than or equal to 20 meters, the transmission power of the wireless AP may be reduced and/or the antenna gain of the wireless AP may be reduced and/or the wireless AP antenna may be replaced by a directional antenna.
In this embodiment, step S3 includes the following steps,
A. actually measuring the signal intensity and the network speed of a cross area between adjacent wireless APs;
B. detecting whether the signal intensity of the middle position between the co-channel wireless APs is lower than the-85 dB co-channel multiplexing requirement or not;
C. for the spatial edge region, the signal strength is detected, and whether the spatial edge region receives the interference of the external channel is considered as a whole.
Example two
In this embodiment, taking fig. 2 and fig. 3 as an example, if the required number of wireless APs is X, the number of channels is N, the network bandwidth requirement of each AP load terminal is a, the number of load terminals is N, and the bandwidth throughput of each AP is b, then X is an/b (rounded up according to one). Wherein the number of channels is known as specified by the department of industry and communications, and the wireless APs are located.
In this embodiment, when the required number X of the wireless APs is less than or equal to the number N of the channels, the required number of APs may be deployed according to different channels used between all the wireless APs in fig. 1, so as to increase the overall speed of the network.
In this embodiment, when the required number X of the wireless APs is greater than the channel number N, the channels need to be multiplexed, and the distance between the adjacent wireless APs in the same channel is ensured to be long enough, and a general AP arrangement in the market is adopted, as shown in fig. 1. When the channel needs to be multiplexed and the space is small and the distance L between the two is not far enough, (calculated by the normal transmission power of 10dB, the distance between the two needs to be at least 20 meters), then the two wireless APs will interfere with each other, the signal-to-noise ratio is poor, the overall network speed does not increase or decrease, and then the distance of the multiplexed channel needs to be reduced by adopting a corresponding method.
In this embodiment, the wireless AP can multiplex channels in a short distance by the following technical method.
1. Reducing the transmitting power of the wireless AP, so that the signal coverage area 5 of the wireless AP is reduced, and the minimum distance of channel multiplexing is reduced;
2. the gain of the wireless AP is reduced, the signal coverage area 5 of the wireless AP can be reduced, and the channel can be multiplexed in a shorter distance;
3. the wireless AP is changed into a directional antenna, so that the central signal intensity of the directional antenna is ensured, meanwhile, the signal coverage range 5 of the wireless AP is reduced, and the channel can be multiplexed in a shorter distance.
In this embodiment, as shown in fig. 3, the above technical method is adopted to limit the signal coverage of the wireless AP and ensure that a smaller distance multiplexing channel is possible.
In this embodiment, in the arrangement method of the multiplexing channel, by attenuating the signal energy and/or controlling the signal energy concentration range, the attenuated signal energy effectively reduces the mutual interference in the co-channel multiplexing process, the interference resistance in the control signal energy concentration is also enhanced, and the signal-to-noise ratio of the multiplexing channel is improved.
In this embodiment, the channel can be multiplexed, and the wireless AP arrangement condition under the condition that the required number of the wireless APs > the channel number can be satisfied. As shown in fig. 4, different channels are deployed between two adjacent wireless APs, the same channel is deployed between two spaced wireless APs (the distance between the two wireless APs with the same channel is greater than the effective channel multiplexing distance), and the wireless APs are deployed in a spatial range Q by multiplexing the channels according to the required number, so that the overall signal-to-noise ratio is improved, the overall network bandwidth is expanded, and each terminal is ensured to obtain a higher network speed.
In this embodiment, in fig. 4, the wireless AP1-1 and the wireless AP1-2 … … are wireless APs deployed by using the same channel as the wireless AP 1; the wireless AP2-1 and the wireless AP2-2 … … are wireless APs deployed by adopting the same channel as the wireless AP 2; the wireless AP3-1 and the wireless AP3-2 … … are wireless APs which are deployed by adopting the same channel as the wireless AP 3; and so on. The dashed circle is the coverage of each wireless AP.
In this embodiment, after the wireless Ap is arranged in the space, the deployment edge effect of the wireless Ap needs to be verified, which specifically includes the following three aspects:
1. and carrying out actual measurement on the signal intensity and the network speed of the crossing area between the adjacent APs.
2. For the gap AP middle position, whether the signal strength can meet the multiplexing requirement of the parameter lower than-85 dB is tested.
3. For the edge areas such as the wall edge, the signal intensity is actually measured and whether the interference of the external channel exists or not is integrally considered.
In a word, the whole standard reaching situation of each part (the possibly risk area is mainly detected) is actually measured according to the requirement for the bandwidth in the space, and construction fine adjustment is carried out according to the measurement.
By adopting the technical scheme disclosed by the invention, the following beneficial effects are obtained:
the invention provides a high-density WIFI system arrangement method, which comprises the steps of multiplexing channels in a short distance, increasing the utilization rate of the channels, breaking through the efficiency bottleneck limit of channel bandwidth, increasing the number of APs, sharing AP loads and improving the speed of the whole network; in addition, the invention can improve WIFI interference of the intranet, improve the signal-to-noise ratio and improve the intranet efficiency in scenes with a large number of loads.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that it is obvious to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present invention, and such modifications and improvements should be considered within the scope of the present invention.
