Difference (unit DB), hbij indicate the antenna effective height (unit M) of j-th of proposed base station in geographical environment i.
It should be noted that village difficult to understand correction model is usually selected when realizing wireless communication network system in the prior art
(Okumora-Hata), it can simplify according to village difficult to understand correction model as basic median propagation loss formula, applicable elements are as follows: frequency
Rate is 150~1500MHz；Antenna for base station effective height is 30~200M；Mobile portable antennas height is 1~10M；Communication distance is
1~35KM.Shown in the formula is specific as follows:
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 transmissions loss, unit DB；F is radio wave frequency, range 150MHz to 1500MHz；

Under the premise of obtaining every kind of geographical environment and corresponding to datum quantity, determine that the antenna effective height of each proposed base station and antenna increase
Benefit, so that the communication radius of corresponding proposed base station can be obtained in the formula for being substituted into above-mentioned calculating communication radius；It is demonstrated experimentally that
In this way realize communication radius prediction can reach accurate prediction effect, and then improve base station selection at
Power and accuracy rate, reduce as addressing it is improper caused by the wasting of resources, interference a series of problems, such as.
A kind of base station selection method of wireless communication network system provided in an embodiment of the present invention calculates every kind of geographical environment
After the communication radius of interior proposed base station, can also include:
The corresponding antenna effective height of different base station and communication radius in every kind of geographical environment are written to pre-set
In relation table, for inquiry；Wherein, base station includes Reference BTS and proposed base station, and the value of Gtij takes 0.
It should be noted that since identical set would generally be chosen when different base station in carrying out wireless communication group network system
It is standby, therefore calculated to simplify, the Gtij in above-mentioned formula can be with value for 0, thus the meter of the realization communication radius of more speed
It calculates.It is further to note that antenna effective height and communication radius are in above-mentioned loss formula in the case where Gtij is 0
Unique variable, therefore the corresponding relationship of the two can be written in relation table, thus later again in corresponding geographical environment
When realizing that the communication radius of base station calculates, if the equipment for realizing base station construction is identical as respective base station in relation table,
It can be directly by determining communication radius corresponding with different antennae effective height in relation table, and then realize base station selection, and
It no longer needs to compute repeatedly, greatly reduces calculation amount.
A kind of base station selection method of wireless communication network system provided in an embodiment of the present invention, determines calculated communication
After the proposed base station that radius meets preset need is the base station that need to be established, can also include:
The corresponding mark in the base station that need to be established is added to wireless communication network system to correspond in the map in geographical location, for
It checks.
It should be noted that can it is pre-rendered go out geographical location corresponding with wireless communication network system map, in turn
The mark for each base station established will be needed to be added in this map, and this map can be shown or be exported
To specified terminal or mailbox etc., thus, it is possible to make staff very clear for the distribution of base station, it is convenient for work people
Member carries out related work.
Illustrating for above-mentioned technical proposal disclosed by the invention is carried out by taking certain city as an example below:
1, according to real work demand, following viable communication demand is proposed:
Whole city's outdoor RF wireless communication coverage rate reaches 100%；

7, antenna for base station effective height under all kinds of geographical environments and communication radius for ease of calculation, are made into corresponding pass
It is table, as shown in table 1- table 4.
8, the position of base station for needing to establish is determined based on aforesaid way, and then completes corresponding wireless communication network system
The network design of system.
In the case that technical solution disclosed in the present application is not for consideration power system capacity in wireless communication network system, is had to,
By setting different types of geographical environment, different geographical environmental criteria amounts are determined respectively by Reference BTS, to estimate it
The communication radius of remaining proposed base station carries out the budget for realizing networking coverage prediction effect.The base of different geographic models is utilized in it
