Outdoor WLAN systems
Overview in relation to non-ionising radiation NIR
Application
WLAN is a freely usable radio technology for transmitting data over short distances. As the transmitted power is low, several such cells can be operated in close proximity within the same frequency band.
With the increasing number of WLAN communication applications there is a requirement for using WLAN as outdoor systems over greater distances. The availability of WLAN systems with directional antennas means that it is now possible to establish links over greater distances.
Outdoor WLAN systems have the same technical characteristics (frequency bands, transmitter power EIRP, field strengths, etc.) as conventional (indoor) WLAN systems. Both are subject to the same technical and regulatory requirements. However, the fact that for outdoor WLAN systems the antennas are generally mounted outside, these transmitters are then considered fixed installations and are subject to the Ordinance on Non-Ionising Radiation and their masts and superstructures must comply with the provisions of local planning law.
This explanation provides the authorities and the public with an overview of the system components and the necessary explanations for understanding some of the technical characteristics. Based on this, the situation regarding licensing and market approval is summarised.
