Abstract

Weather radars are used for short term meteorological prediction all over the world. Radars in 5 GHz band can be jammed by RLAN devices (e.g. Wi-Fi routers). We introduce the background of this problem, and analyze the weakness of the current solution (DFS - dynamic frequency selection). We propose some other solutions, and introduce our channel allocation technique. We analyze it theoretically by modeling the radar operation and RLAN traffic, and we also show its high efficiency in practice, based on well-known IEEE 802.11 RTS/CTS mechanism.
