The invention discloses a telephone traffic based electromagnetic radiation exact prediction method of a GSM base station. The telephone traffic based electromagnetic radiation exact prediction method of the GSM base station comprises the specific steps of firstly obtaining telephone traffic data and a total carrier number of the base station during a period of time through an operator, and performing weighted average calculation on the telephone traffic by regarding hour as a unit so as to obtain an average telephone traffic of each carrier frequency of the base station per hour; calculating the actual transmission power of each single carrier frequency in the presence of different telephone traffic based on the obtained average telephone traffic and the Erlang-B formula; and predicting the electromagnetic radiation intensity aroused by single carrier frequency of the base station by using the actual transmission power of the single carrier frequency of the base station. The telephone traffic based electromagnetic radiation exact prediction method of the GSM base station gives consideration to the influence from the change of the telephone traffic to the electromagnetic radiation intensity around the base station, can predict and estimate the electromagnetic radiation intensity exactly and simply, has an extremely great reference value for base station construction, environment effect assessment and environment protection and has certain social benefits.

Description

technical field [0001] The invention relates to a method for accurately predicting electromagnetic radiation of a GSM base station based on traffic volume. Background technique [0002] As the number of communication base stations increases year by year, it is more and more important to predict the intensity of electromagnetic radiation around the base stations. At present, when studying the distribution of electromagnetic radiation around the base station or predicting the intensity of electromagnetic radiation, most of the predictions are based on the maximum transmit power of the base station. This prediction often deviates greatly from the actual measurement results. This is because GSM uses TDMA technology. The transmission power changes with the volume of traffic. When the communication traffic of the base station is large, the average transmission power of the base station will increase, and the electromagnetic radiation intensity around the base station will increase...

The patent document CN103874090A has been published, which discloses a method for predicting electromagnetic radiation of GSM communication base stations, which uses a power spectral density function to predict electromagnetic radiation. However, this patent needs to count the average value of pulse current density, and the procedure is cumbersome and time-consuming. In addition, When the actual transmission power is obtained by integrating the power spectral density, researchers need to grasp the signal bandwidth of the integration very accurately, otherwise it will have a certain impact on the accuracy of the prediction
