  1 Safety  Issue    (02) Huawei Proprietary and Confidential                                     Copyright © Huawei Technologies Co., Ltd. 1-11  1.3 Electromagnetic Field Exposure Introduction The Base Transceiver Station (BTS) emits Radio Frequency (RF) radiation. Follow the local safety regulations when installing and operating the BTS to avoid radiation hazard. Location of Base Station Antennas Base station antennas, the source of the radiation, are usually mounted:  On freestanding towers, with a height up to 30 m  On a tower on the top of buildings  To the side of buildings, on rare occasions   Generally, the antenna cannot be located in a position lower than 10 m. The energy usually forms a horizontal main beam and is slightly tilted downwards. The remaining energy forms into weaker beams on both sides of the main beam. The main beam, however, does not reach the ground if the antenna is around 50–200 m away from the ground. The highest level of emission would be expected in close vicinity of the antenna and in line of sight to the antenna. Exclusion Zones The requirements for exclusion zones are as follows:  The antenna should be properly located to prevent the public from accessing the area where the RF radiation exceeds the previously mentioned limits.  If areas with excessive RF radiation are accessible to the operation and maintenance (O&M) personnel, ensure that they know the source of radiation and can power off or shut down the transmitters before entering high radiation areas. In addition, such areas must be confined within a distance of 10 m from the antennas.  Each exclusion zone should be defined by a physical barrier and by a recognizable sign warning the public or O&M personnel. Guidelines on Choosing Antenna Sites The guidelines on choosing the antenna sites are as follows:  For roof-mounted antennas, raise the antennas above the height of the personnel who may have to work on the rooftop.  For roof-mounted antennas, keep the transmitter antennas away from the areas accessible to the public, such as roof access points, telephone service points, and HVAC devices.  For roof-mounted directional antennas, place the antennas near the periphery, and do not make the antennas face the building.  Consider the trade-off between large aperture antennas (lower maximum RF) and small aperture antennas (lower visual impact).  Keep higher-power antennas away from accessible areas.  Keep the antennas in a site that is far away from urban areas, though this may contradict the coverage area requirements.
1 Safety    1-12 Huawei Proprietary and Confidential                                     Copyright © Huawei Technologies Co., Ltd. Issue    (02)   Exercise extra caution when designing co-location sites, that is, antennas owned by different companies are located in the same site or are co-sited. This applies particularly to sites that include high-power broadcast (FM/TV) antennas. Local zone often favors co-location, but co-location may cause safety problems.  Take special precautions for antenna sites near hospital and schools. Location of BTS The BTS is shielded from RF radiation hazards. The device has been tested to comply with the radioactive spurious emission requirements of international standards or local regulations. Therefore, the BTS under normal operating conditions does not cause danger to the public and O&M engineers. However, the limits for RF radiation might be exceeded due to faulty antenna cables or for other causes.  BTS sites shall not be accessible to the public. Only authorized and trained personnel can access BTS sites or equipment rooms.  A sign of excessive RF radiation must be present on the doors of the sites or equipment rooms to warn the personnel inside the site or equipment room of excessive RF radiation.  BTS sites must be regularly monitored and inspected after installation. Prediction of the Exposure to Electromagnetic Fields This 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 reflection, deflection, and scattering of electromagnetic fields. The maximum output power (given in EIRP) of a BTS is usually limited by license conditions of the network operator. A rough estimation of the expected exposure in power flux density on a given point can be made with the following equation: S = (P(W) x Gnumeric)/(4 x r²(m) x π) Where, P = Maximum output power at antenna port of the BTS in W Gnumeric = Numeric gain (see below) r = Distance between the antenna and the point of exposure in meters For the calculation of the Gnumeric, Gnumeric = 10GdB/10 GdB = Gantenna(dB) – Bcable(dB) – Bvertical-attenutation(dB) – Bhorizontal-attenuation(dB) B = attenuation in dB
