Quietly off the stage of WWDC, the AirPort Express was kicked up a notch and now looks more like its sibling, the Apple TV. The AirPort Express now supports simultaneous dual-band 802.11n Wi-Fi.
The new AirPort Express supports simultaneous dual-band 802.11n Wi-Fi. That means it transmits at both the 2.4GHz and 5GHz frequencies at the same time. So no matter which band your wireless devices use, they’ll automatically connect to the best available band for the fastest possible performance.
