I'm trying to determine the differences in features of the various Atheros chipsets supported by ath9k. Please note, I have only chosen dual band parts with at least 2 spatial stream support, as the single band parts are generally subsets of the dual band parts and the <2 spatial stream parts are generally extremely value-oriented (or power oriented.)
Gen 1 - AR5008: AR5416+AR5122 - 2x2 dual band, PCI AR5416+AR5133 - 3x3 dual band, PCI AR5418+AR5133 - 3x3 dual band, PCIe Gen 2 - AR9001: AR9160+AR9104 - 2x2 dual band, PCI AR9160+AR9106 - 3x3 dual band, PCI Gen 3 - AR9002: AR9220 - 2x2, dual band, PCI AR9280 - 2x2, dual band, PCIe Did I miss any 2x2 or better 802.11n radios? Questions: 1) What differences exist between the AR5133 and AR9106? If the AR9106 offers 3x3 with superior performance to the AR5008, why didn't they ever offer any kind of PCIe option? 2) What is the advantage of the AR9002 family over the AR9001 family? Obviously, the AR9002 is a single chip solution, likely reducing cost, power and size. But is there any improvement to radio functionality or other features? Note, I am interested in 802.11n features supported, quality of implementation, relative effective sensitivity, pretty much everything on the radio / DSP / layer 1 angle of things. I am curious as I want to be able to make the most appropriate hardware choices, and frankly, testing these chipsets to try and figure this out isn't the best way to do this based on my experiences thus far... -Galen _______________________________________________ ath9k-devel mailing list [email protected] https://lists.ath9k.org/mailman/listinfo/ath9k-devel
