In this embodiment, the communication radius that can be realized by the base station is taken as the coverage area of the base station. Specifically, when the calculation of the communication radius that can be realized by the base station is realized, a real base station can be actually established in each geographic environment in a one-to-one correspondence manner as a reference base station; after the reference base stations are established, the effective height and the communication radius of the antenna of each reference base station can be obtained through actual measurement, and then the corresponding reference quantity is calculated based on the effective height and the communication radius of the antenna. The reference quantity is a fixed parameter quantity which is required to be used when the communication radius of the base station located in the reference quantity is calculated in the corresponding geographic environment, namely the same parameter quantity which is required to be used when the communication radii of all the base stations in the corresponding geographic environment are calculated; thus, after calculating the reference quantity in each geographic environment, the communication radius of different base stations in each geographic environment can be predicted based on the reference quantity.

In the technical scheme disclosed by the invention, aiming at different geographic environments, a real base station is established in each geographic environment as a reference base station, the fixed parameter quantity required for realizing communication radius calculation of different base stations in each geographic environment is calculated through the antenna effective height and the communication radius of each reference base station obtained by actual measurement, the communication radius of the corresponding proposed base station is further calculated based on the fixed parameter quantity and the virtual antenna effective height of the proposed base station, and whether the corresponding proposed base station meets the requirement or not is determined based on the communication radius, namely whether the base station can be actually established at the corresponding position of the proposed base station or not is determined, so that the address selection of the base station is realized. Therefore, the coverage prediction of the proposed base station in different geographic environments is realized by using the benchmarks of different geographic environments, and the site selection of the base station is realized based on the prediction result.

calculating a reference quantity Xi of the geographic environment i according to the following formula:
Xi＝(44.9－6.55lg(hbi))×lg(di)－13.82lg(hbi)，
wherein di represents the communication radius of the reference base station in the geographic environment i, and hbi represents the effective height of the antenna of the reference base station in the geographic environment i;
correspondingly, calculating the communication radius of the proposed base station in each geographic environment may include:
calculating the communication radius dij of the jth proposed base station in the geographic environment i according to the following formula:
lg(dij)＝(Xi+Gtij+13.82lg(hbij))÷(44.9－6.55lg(hbij))，
wherein Gtij represents the antenna gain difference (in DB) between the jth proposed base station in the geographic environment i and the reference base station in the geographic environment i, and hbij represents the antenna effective height (in M) of the jth proposed base station in the geographic environment i.
It should be noted that, in the prior art, an Okumora-Hata correction model is usually used when a wireless communication networking system is implemented, and the Okumora-Hata correction model can be simplified into a basic propagation loss median formula according to the Okumora-Hata correction model, and the application conditions are as follows: the frequency is 150-1500 MHz; the effective height of the base station antenna is 30-200M; the height of the mobile station antenna is 1-10M; the communication distance is 1-35 KM. The formula is specifically shown below:
LT＝69.55+26.16lg(f)－13.82lg(hb)－a(hm)+(44.9－6.55lg(hb))×lg(d)+LD+LF－GT－GR；
wherein, LT is radio wave transmission loss, unit DB; f is the radio frequency, ranging from 150MHz to 1500MHz; hb is the effective height of the base station antenna, and the application range is 30M to 200M; a (hm) is a mobile antenna correction factor; hm is the effective height of the mobile station receiver antenna; d is the communication radius in KM; LD is diffraction loss, unit DB; LF is antenna feeder loss, unit DB; gt is the transmitting antenna gain, unit DB; GR is the receive antenna gain, in DB. Under the conditions of networking equipment determination and feasible communication requirement determination, LT, f, a (hm), gt and GR can be regarded as constants, wherein LT is determined by the feasible communication requirement; f. a (hm), gt and GR are determined by networking equipment; LF is the loss of the antenna feeder, and the loss of the antenna feeder depends on the length of a feeder line; different building structures, building density and diffraction loss LD generated by the wireless signals with different street widths are different.
Based on the loss formula, the total parameters except the antenna effective height and the communication radius are used as reference quantities according to the expression, and then after the antenna effective height and the communication radius of each reference base station are obtained through measurement, the reference quantities of the geographic environment i (i =1,2.. N) can be calculated according to a formula of Xi = (44.9-6.55 lg (hbi)) × lg (d) -13.82lg (hbi)), wherein the effective antenna height is obtained by subtracting the ground altitude from the corresponding base station antenna altitude; on the premise of obtaining the reference quantity corresponding to each geographic environment, determining the effective height and the antenna gain of the antenna of each proposed base station, and substituting the effective height and the antenna gain into the formula for calculating the communication radius to obtain the communication radius of the corresponding proposed base station; experiments prove that the communication radius prediction can achieve a more accurate prediction effect by the mode, so that the success rate and the accuracy of site selection of the base station are improved, and a series of problems of resource waste, interference and the like caused by improper site selection are reduced.
The method for selecting the address of the base station of the wireless communication networking system provided by the embodiment of the invention can also comprise the following steps after the communication radius of the simulated base station in each geographic environment is calculated:
writing the effective heights and the communication radiuses of the antennas corresponding to different base stations in each geographic environment into a preset relation table for query; the base station comprises a reference base station and a proposed base station, and the value of Gtij is 0.
It should be noted that, since the same device is usually selected when different base stations in the wireless communication networking system are performed, gtij in the above formula may be set to 0 in order to simplify the calculation, so as to realize the calculation of the communication radius more quickly. It should be noted that, when Gtij is 0, the effective antenna height and the communication radius are the only variables in the loss formula, so that the correspondence between the effective antenna height and the communication radius can be written into the relationship table, and therefore, when the communication radius of the base station is calculated in the corresponding geographic environment, if the equipment for implementing the base station construction is the same as the corresponding base station in the relationship table, the communication radius corresponding to the effective antenna height can be directly determined from the relationship table, and the base station address selection can be implemented without repeated calculation, thereby greatly reducing the calculation amount.
The method for selecting a site of a base station in a wireless communication networking system according to the embodiment of the present invention may further include, after determining that a proposed base station with a calculated communication radius meeting a preset requirement is a base station to be established:
and adding the base station corresponding identification to be established into a map of the corresponding geographic position of the wireless communication networking system for viewing.
It should be noted that a map of a geographical location corresponding to the wireless communication networking system may be drawn in advance, and further an identifier of each base station that needs to be established is added to the map, and the map may be displayed or output to a designated terminal or mailbox, etc., so that the distribution of the base stations may be clear to the staff, and the staff may conveniently perform related work.

The same antenna is used for each reference base station, and the feeder loss difference is ignored, namely Gtj =0.
4. Obtaining X values of base stations in each geographic environment according to the measured data
According to the measured data, values of 350M base stations hb and d under different geographic environments are substituted into a model formula X = [ 44.9-6.55lg (hb) ] X lg (d) -13.82lg (hb), so as to obtain:
a type: x = -16.54
A/B type: x = -13.05
