A communication base station, also known as a public mobile communication base station, is a form of wireless radio station that transmits information to and from mobile phone terminals through a mobile communication exchange center within a limited radio coverage area. A base station is the basic unit that constitutes a cellular cell in mobile communication, completing communication and management functions between the mobile communication network and mobile communication users. The generalized communication base station is the abbreviation of Base Station Subsystem (BSS). Taking GSM network as an example, it includes base station transceiver (BTS) and base station controller (BSC). A base station controller can control dozens or even dozens of base station transceivers. In systems such as WCDMA, similar concepts are called NodeB and RNC. Narrowly defined communication base station, i.e. public mobile communication base station, is a form of wireless radio station that refers to a radio transceiver station that transmits information to and from mobile phone terminals through a mobile communication exchange center within a certain radio coverage area. The power density of communication base stations is generally between 0.6 and 2.0 microwatts per square centimeter（ μ W/cm2), belonging to low-frequency radiation. A study by the World Health Organization from 1996 to 2006 showed that excessive electromagnetic radiation is only harmful to the human body, while low-frequency electromagnetic radiation has a weak impact on human health
