|VR-Zone revealed that GIGABYTE will be offering an add-on card which will add Bluetooth 4.0 and WiFi to your computer. This card uses PCI Express x1 interface. It is actually a PCI Express to mini PCI Express adapter which takes a half-sized mini PCI card. This mini PCI card will be connected to two antennas on the back and itâ€™ll enable WiFi for your computer. GIGABYTE is using an Atheros chip for WiFi functionality. For Bluetooth 4.0, there is a USB pin header which can be connected to USB pin header on the motherboard. A standard USB port is also present on the card, you can plug any USB flash drive to it.|
Original source is VR-Zone but its not opening at my end for some reason.
Anyhow, i must say, a clever approach by Gigabyte. They should have give more antennas so that we can upgrade the mini card in future.
