With the large-scale construction of 4G base stations

4G base station’s environmental impact assessment work is also more and more. The 4G base station is using a frequency of more than 2GHz

the signal attenuation is far greater than the 900 MHz system. But the existing environmental impact assessment standard does not consider the difference between high frequency and low frequency

so in this paper

we discussed on the 4G mobile communication base station EIA

and put forward a test method.
