WiGig cards will deliver data transfer rates up to 7Gbit/s nearly 50x faster than the highest 802.11n devices. The device will remain compatible with existing WiFi devices.
The 7Gbit/s speed is fully dependent on the devices being within sight of each other.
The 7Gbit/s rate makes use of the 60Ghz band which cannot go through walls etc. When roaming away from line of sight the device will drop to lower bands (rates of data transfer) which can transfer through walls and other obstacles.
The screenshot below is for installation of WiGig card 1601 within a Latitude E6540.
The card card utilises the same slot as the wireless, although it has three antennas instead of two to be connected. It does not allow support with another Bluetooth device in the system at the same time.
