Embodiment Construction

[0036] The present invention will be further described below in conjunction with the accompanying drawings.

[0037] refer to figure 1 , to further describe the specific steps for realizing the present invention.

[0038] Step 1, deploy access point AP and communication equipment.

[0039] The layout density in the indoor area is 3 / 10m 2 The access point AP, as the first type of access point, the deployment density is 1 / 10m 2 communication equipment.

[0040] Step 2: Obtain a sample set of indoor ambient noise.

[0041] In the indoor area, 50 observation points are randomly selected as the first type of observation points, and the signal strength of the nearest access point AP at each first type of observation point is continuously collected 30 times, and the average value is taken.

[0042] Subtract the average value of the signal strength at each observation point from the signal strength of the access point AP received each time at each first type of observation point ...

Abstract

The invention discloses an access point power optimization method based on an indoor propagation loss model, and mainly solves the problems that in an existing indoor access point transmitting power optimization method, the overall energy consumption is increased, and the overall energy consumption reduction effect is poor. The method comprises the following steps: (1) arranging an access point APand communication equipment; (2) acquiring an indoor environment noise sample set; (3) calculating the energy loss of each wall; (4) calculating an indoor path attenuation index; (5) constructing anindoor propagation loss model; and (6) obtaining the minimum value of the total sending power of the first type of access points in the indoor area. According to the method, the minimum value of the total transmitting power of the indoor AP is obtained by constructing the indoor propagation loss model and utilizing the Lagrange multiplier method, so that the energy consumption of the indoor regional AP is reduced.

Description

technical field [0001] The invention belongs to the technical field of communication, and further relates to an access point transmission power optimization method based on an indoor propagation loss model in the wireless communication technology.
