In-building systems
In-building systems and RF exposure
In GSM and WCDMA in-building systems the antennas transmit low-power radio frequency (RF) signals in the frequency range between 900 and 2200 MHz. In-building systems with distributed antennas can be planned in various ways. The more antennas used the lower the output power level needed for good coverage and capacity. The antennas can transmit in one (directional), two (bi-directional) or all directions (omni-directional). The maximum input power for in-building antennas, and pico radio base stations with integrated antennas, is usually less than 1 W (30 dBm).
For distributed antenna configurations with 1 W input power, the RF exposure compliance distance for the general public is less than 10 cm. In other words, it is possible to be as close as 10 centimeters away from the antenna without being exposed to levels exceeding the safety limits.
