An experimental evaluation of the Dynamic Frequency Selection (DFS) algorithm for weather radar and WLAN/RLAN coexistence in the 5GHz band.
The issue of interference to meteorological radars from Wireless Local Area Network (WLAN) and Radio Local Area Network (RLAN) or WAS/RLAN [1] systems operating in the 5 GHz band are on the agenda of several groups and committees since long time as initial issues of coexistence are dated more than 10 years ago. Radio Frequency Interference (RFI) is one of the main issues in weather radar community as data quality and post-processing algorithms can be negatively impact by interferences. On the basis of the World Radiocommunications Conference in 2003, C-band radars share their operational frequency band with WLAN/RLAN and WLAN, which may lead to causing interferences in weather radar systems.
The European Commission Joint Research Centre (EC DG JRC) has started to investigate in 2020 the matter of coexistence between meteorological radars as part of the overall activity on radio frequency coexistence between wireless services. The identification of the policy options and their assessment on various dimensions was performed in a previous JRC technical report JRC125475, which also identified the need for specific experimental activities which can be conducted at the JRC. In the report JRC125475, these options were listed as options 21,23,24.
This technical report describes the experimental activities conducted in the JRC to evaluate the options identified above and the obtained results
