Detailed Information on 802.11n Protocol Stack

Hi,

I'm afraid you will have to wait for Sebastian Max to come back from
vacation by the end of July to answer you your question.

Greats,

Mac Muehleisen

Dear Hendrik,

Considering the MIMO antenna configuration: The 3x3 is of course just a suggestion. In fact, the MIMO-enabled rate adaptation tries to optimize the number of streams, given the number of tx and rx antennas. Hence, it might happen that although 3x3 is available, only 1 stream is used (which allows reception diversity and thus an SNR gain). You can configure any number of antennas for any device.

Currently, there is no dynamic/time variant channel implementation, apart from the possibility to configure a time-dependent fading channel; Especially, there is no implementation of a channel model according to TGn.

BR,
Sebastian
