+ - **wifi links**
+
+ This demonstrates how to declare a wifi link in your platform and
+ how to use it in your simulation. The basics is to have a link
+ which sharing policy is set to `WIFI`. Such links can have more
+ than one bandwidth value (separated by commas), corresponding to
+ the several SNR level of your wifi link.
+
+ In this case, SimGrid automatically switches to validated
+ performance models of wifi networks, where the time is shared
+ between users instead of the bandwidth for wired links (the
+ corresponding publication is currently being written).
+
+ If your wifi link provides more than one SNR level, you can switch
+ the level of a given host using
+ :cpp:func:`simgrid::s4u::Link::set_host_wifi_rate`. By default,
+ the first level is used.
