Atheros claimed a minor breakthrough on Monday through a new addition to its ROCm chips. The AR6003 is billed as not just a rare single-chip 802.11n Wi-Fi part for smartphones and other handhelds but also the fastest of its kind. It takes advantage of features that aren't always used in 802.11n to boost the maximum speed up to 85Mbps in real situations when on the 5GHz band. The technique has the side benefit of increasing the usable range of a handheld compared to older 802.11g wireless.
