Wireless-AD - the next generation WiFi (WiGig) with Gigabit per second speed

Perhaps many of you have just upgraded your WiFi network from Wireless-N to Wireless-AC just like me, the next generation of wireless network namely IEEE 802.11ad has already come to the market.

Instead of operating at the highly congested 2.4 GHz band or the less congested 5 GHz band, wireless-AD (a.k.a. WiGig) operates at a new 60 GHz band. The key selling point of this wireless-AD network technology is that it is able to provide an unprecedented  throughput as high as 7 Gbps, which is even much more faster than the wired Gigabit Ethernet network!

However, the wireless-AD network, operating at 60 GHz band, has even shorter range than the 5 GHz band WiFi, and it find itself more difficult to penetrate through walls and other physical obstacles. In addition, its performance is degraded by the amount of oxygen in the air!

With these limitation, wireless-AD might require an open space environment with less oxygen in the air (such as at high altitude places) to transmit data at high speed to nearby devices that support the technology.

Some possible uses of wireless-AD could be media server transferring super UHD movie to nearby TV, "wireless external SSD hard disk", "wireless thumb drive without USB need", etc.

TP-Link has already come out with the Talon AD7200 Multi-Band WiFi Router that supports wireless-AD technology. However, many wireless devices are yet to catch up with this new technology.

Anyhow, it is already supported in the Qualcomm Snapdragon 820 processor which is inside the Samsung Galaxy S7, Samsung Galaxy S7 Edge, LG G5, Moto Z, Sony Xperia X Performance, XiaoMi Mi 5, and the newly launched HTC 10.

It is expected to be also supported in the upcoming Samsung Galaxy Note 7. However, it is still unclear whether Apple iPhone 7 will support wireless-AD or not.
