At the World Radiocommunication Conference 2003 (WRC-03), the decision was made to provide a primary allocation for the implementation of wireless access systems (WAS), including RLAN, in the bands 5.150-5.350 and 5.470-5.725 GHz, as long as they do not cause interference to incumbent services such as C-band weather radars (ITU Resolution 229; www ,itu.int/oth/R0A06000018/en).
Following the initial interference cases in Europe, the DFS specifications in the European Telecommunications Standards Institute (ETSI) Standard EN 301 893 have been modified to impose a 10-min channel availability check (CAC) for RLAN channels covering the 5.60-5.65-GHz band, together with solving other problems that were highlighted such as the minimum pulse width (down to 0.5 ^s) and the consideration of the variety of complex weather radar waveforms (fixed, interleaved, or staggered PRF) for which a number of new test signals were added.
In this respect, it is now imperative that worldwide weather services as well as radar operators and manufacturers proactively involve themselves in the radio frequency management process and work in close contact with their national radio authorities to ensure that meteorological interests be duly taken into account in any decision-making process toward the future usage of any wireless devices (such as RLAN) within or close to weather radar frequency bands.
