Disabling transmission of beacon frames

[Jan Bakuwel <jan.bakuwel@gmail.com>]

Hi all,

As far as I'm aware, IEEE802.11 defines the two modes a wifi AP and
client can establish communication, passive (AP broadcasts SSID, clients
connects to SSID) and active (AP doesn't broadcast SSID, client
broadcasts SSID probe and AP then sends a probe response).

Does anyone know if it's possible to disable passive mode on an AP? It
is possible to set the SSID to hidden but this does not stop the
broadcasts, it just broadcasts frames with a null SSID. Stopping the
broadcasts altogether (and as a consequence the client must use active
mode, ie. needs to send probes) will result in no EMR when wifi is not
in use, in other words AP will only listen not transmit in that case,
yet wifi is available when needed.
