Operators have to follow the related local regulations when erecting the BTS. Operators of BTSs must also follow the related local regulations when erecting the BTS. 3.4.2 Limits and Guidelines on Exposure to Electromagnetic Fields There are a number of international regulations, standards and guidelines for exposure to electromagnetic fields. Several European countries have adopted the recommendation of the council of the European Union. It was released on July 12, 1999 focusing on the harmful effects of exposure to electromagnetic fields (1999/519/EC). The recommendation is based on the guideline published by the ICNIRP. Table 3-1 gives a comparison among regulations and reference levels applied in different countries.

The basic restriction on exposure to electromagnetic fields is based on established health effects and biological considerations. 3.4.3 Location of Base Transceiver Station The base transceiver station (BTS) is shielded from RF radiation hazards. The pBTS3701 does not cause danger to the public and workers under normal operation condition. The pBTS3701 shall be regularly monitored and inspected after installation. 3.4.4 Prediction of the Exposure to Electromagnetic Fields The section provides a theoretical approach to calculate possible exposure to electromagnetic radiation around a BTS antenna. Precise statements are possible either with measurements or complex calculations considering the complexity of the environment, such as soil conditions, nearby buildings and other obstacles. The complexity may cause reflections and deflection, scattering of electromagnetic fields. The maximum output power (given in EIRP) of a BTS is usually limited by license conditions of the network operator. For the pBTS3701, the maximum output power of the TRX is.500 mW (27dBm). A rough estimation of the expected exposure in power flux density on a given point can be made with the following equation: Where P = Maximum output power in W G numeric = Numeric gain (see below) r = Distance between the antenna and the point of exposure in meters For the calculation of the numeric Gain: 1010GdBnumericG=
