The mobile EIA of base station acceptance criteria and requirements of environmental protection departments are getting higher and higher.If not through the EIA acceptance
the base station will not be built allowably. The key parameter setting for the base station in the EIA acceptance will be critical.Main parameter is the transmitting power and downtilt angle.his paper will in-depth study on how to set the transmission power and downtilt angle
and the setting standards will be applied to engineering practice.
