The current hardware is 2.4Ghz 802.11N, i.e., not dual band. We are working on a dual band device. Originally we were targeting to make it available first quarter this year, but it’s taking longer than we expected. We’ll try to make it available as soon as we can, but we won’t release anything until it’s ready.
The current hardware is OEM, roughly equivalent to the Asus RT-N14U, with 8MB flash and 64MB RAM.
