Problems solved by technology

[0010] In the existing wireless network planning, the ultimate goal of design is network performance indicators such as coverage, capacity, and quality. When planning site and power configuration, the judgment of the rationality of the planning results only considers whether the network performance can meet expectations The standard, that is, only considers the distribution density and power intensity of the designed base stations to achieve the expected reference signal received power RSRP, signal-to-interference and noise ratio SINR, throughput and other indicators after the network is built. As long as the standard can be met, it is qualified In the network planning stage, whether the electromagnetic radiation generated by the base station is within the specified electromagnetic radiation standard is not considered in the network planning stage, that is, the influence of the electromagnetic radiation of the base station on the human body is not considered in the existing wireless communication network planning
In network planning, there is a lack of control over electromagnetic radiation. For example, if the base station is too densely designed or the base station transmits too much power, it may cause the electromagnetic radiation emitted by the base station to exceed the specified electromagnetic radiation standard, which will pollute the environment. The human body under the cover may cause irreversible harm

Embodiment 1

[0098] Example 1: Taking my country's electromagnetic radiation protection regulations GB8702-88 as an example, the public exposure derivation limit in the electromagnetic radiation protection limits stipulated in my country is the average value of the parameters of the environmental electromagnetic radiation field within 24 hours in any continuous 6 minutes Should meet: frequency range 30-3000MHz, power density P d Not more than 0.4W / m 2 , that is, the preset electromagnetic radiation intensity parameter is the power density P d Not more than 0.4W / m 2 . According to the commonly used values, the value of the antenna gain is generally 15dBi, and the value of the feeder loss is 1dB. Using the formula 10LogG=antenna gain-feeder loss, the main lobe gain of the antenna is G=25.12, and the value of the direction coefficient f(θ) is 0.5 , the distance r between the measurement point and the transmitting antenna of the base station is 10m, and the power density P d The value is 0....

Embodiment 2

[0099] Embodiment 2: Taking the Wallonia region of Belgium as an example, the electromagnetic radiation standard with a frequency of 2.6 GHz in this region is that the electric field strength E should not exceed 4.5 V / m, that is, the maximum value of the electric field strength E is 4.5 V / m. use the formula Get the power density P in Wallonia, Belgium d The maximum value is 0.054W / m 2 , and the power density P in the electromagnetic radiation standard stipulated in my country in Example 1 d The maximum value of 0.4W / m 2 It is much stricter than that. Therefore, when building a communication network in Wallonia, Belgium, the wireless network planning should comply with the electromagnetic radiation standards specified in the area. With power density P d The maximum value is 0.054W / m 2 Carry out planning, other parameter value and calculation method are the same as embodiment 1, utilize formula It is estimated that the maximum value of the average transmit power P of th...

Abstract

The invention relates to a wireless network planning method and device. Due to the wireless network planning method and device, a planned wireless network meets electromagnetic radiation standards while meeting network performance, practicality and safety of wireless network planning are taken into account, 'electromagnetic pollution' generated when electromagnetic radiation exceeds the standards is avoided, and then damage to human bodies and the environment by the 'electromagnetic pollution' is avoided. The method includes the steps that the maximum transmitting power of cell reference marks is determined according to electromagnetic radiation intensity parameters; according to the maximum transmitting power of the cell reference marks, electromagnetic radiation network simulation and network service performance simulation are performed; when an electromagnetic radiation simulation result obtained through electromagnetic radiation network simulation and / or a network service performance simulation result obtained through network service performance simulation do / does not meet preset conditions, the electromagnetic radiation network simulation and network service performance simulation are performed again until the electromagnetic radiation simulation result and the network service performance simulation result both meet the preset conditions.

Description

technical field [0001] The present invention relates to the communication field, in particular to a wireless network planning method and device. Background technique [0002] The human body lives in the environment of electromagnetic radiation all the time. When the electromagnetic radiation exceeds a certain frequency and power, "electromagnetic pollution" will be generated, which will cause harm to the human body and the environment. Mobile communication base stations transmit information through electromagnetic waves, and excessive radio frequency radiation will bring many acute or chronic hazards to the human body. [0003] The World Health Organization (WHO) survey shows that electromagnetic pollution caused by excessive electromagnetic radiation can induce serious diseases such as cardiovascular and cancer, and also cause damage to the nervous system and reproductive system. Electromagnetic radiation is divided into ionizing radiation and non-ionizing radiation. Radio...
