Hi list, we test pretty old hardware based on AR5414 chip with pretty old madwifi driver, which even use binary hal. Our spectral analyzer shows that in 2.4GHz band this chip transmits OFDM-preamble with any of the OFDM rates (6-54 mbps), instead of .11b-compatable DSSS-preamble. Does anybody could provide some clue: is this chip supports DSSS-OFDM mode according to section 19.7 of IEEE 802.11-2012?
When I digging the ath5k code I faced the AR_PHY_MODE (0xa200) register, which seems to controls the behavior of chip. This register contains two interesting bit: AR_PHY_MODE_MOD_CCK bit 0 (0x00000001) AR_PHY_MODE_MOD_DYN bit 3 (0x00000004) If I am correctly understand, _MOD_DYN just enables the CCK (DSSS) block. But what the purpose of the AR_PHY_MODE_MOD_CCK bit? -- BR, Sergey _______________________________________________ freebsd-wireless@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-wireless To unsubscribe, send any mail to "freebsd-wireless-unsubscr...@freebsd.org"
