The R52n miniPCI is documented to have "Support for up to 2x2 MIMO with spatial multiplexing". Indeed the board layout contains two identical RF stages with filters and tx amplifiers / rx pre-amplifiers (SiGE SE9523) and antenna connectors. Having scanned through all present ath9k code for things related to antenna choice i saw in several places (beacon.c, rcvc.c) some code that determines an antenna. But the resulting values do not get applied. Aso the tx descriptor structures do not contain antenna information, unlike in ath5k and madwifi. Hope that somebody can shed some light on what these chipsets that ath9k is meant for can or cannot do in terms of antenna choice. And how to control it and switch between full 2x2 mimo 80211n and bgn style with single or sectored antennas. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
