Example Embodiment

[0016] After determining the distribution coordinates and transmit power of wireless base stations in the detection and evaluation area, use computer software simulation to intuitively simulate the coverage of cell base stations based on a given signal-to-interference ratio threshold or signal-to-interference-to-noise ratio threshold. area, calculate the signal-to-interference ratio (SIR) or signal-to-interference-to-noise ratio (SINR) of each user, and compare it with the signal-to-interference ratio threshold or the signal-to-interference-noise ratio threshold. The final actual cell coverage is the percentage of the final value of the counter and the total number of virtual users, and the cell capacity is calculated using the previously calculated SIR value or SIR value and the capacity formula.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] In two-dimensional space, the ideal base station distribution is ...

Abstract

The invention discloses a method for detecting and evaluating the coverage rate and the capacity of a wireless base station cell. By collecting information such as the position coordinates of wireless base stations, the transmitting power and the like of a region to be detected and evaluated and setting up two-dimensional lines with the same signal to interference ratio or the same signal to noise ratio, based on preset threshold values, of all the base stations in the region through computer simulation, all the two-dimensional lines with the same signal to interference ratio form closed loop curves, the sum of the areas of the regions defined by all the closed loop curves is the total coverage area of the base stations in the region, and coverage rate and capacity calculation is conducted on the region to be detected and evaluated by computer programs through the statistical method. According to the method, certain material and labor can be saved in the wireless communication networking link, and the method has great value for optimizing network networking, saving construction cost of the base stations and the like.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a technology for detecting and evaluating the cell coverage and capacity of a wireless base station. Background technique [0002] In cellular wireless communication systems, base stations are deployed on a large scale in order to solve problems such as seamless network coverage and high-quality data transmission. In some hotspot areas, a scene of mixed deployment of macro base stations, micro base stations, and pico base stations has even formed. The detection and calculation of the coverage and capacity of the current wireless base station cells usually use the method of on-site drive test measurement with instruments and meters. This method needs to be checked point by point, which consumes a lot of time and manpower. A simple and convenient theoretical detection and evaluation method. Contents of the invention [0003] The purpose of the present invention i...
