It was no surprise when Atheros announced at CES their new AR7400 fourth-generation powerline chipset and that it was IEEE 1901 compliant.
Today Gigle surprised everybody with the announcement that Gigle's currently shipping chips can be made IEEE 1901 compliant by a "simple firmware upgrade".
Before this announcement, Atheros was clearly in the lead for bring IEEE 1901 devices to market. Not any more.
Wonder when the G,hn vendors will have any chips. Looks that they are at least a year behind IEEE 1901, so wait for CES2011.
