Faster, Faster and Even Faster: 802.11ad

Wi-Fi speeds are about to get faster. A lot faster. As cable and fiber providers are deploying gigabit internet connections to offices and to homes, Wi-Fi has not really been keeping up. While many wireless access points and routers tout gigabit speeds, throughput rarely meets the theoretical speeds that are listed in the specs.

That’s changed with the arrival of 80211ad that is bringing really fast Wi-Fi that can keep up with its wired equals. Basically, the WiGig specification makes it possible for devices to communicate without wires at multi-gigabit speeds, thus delivering the wired gigabit connection, wirelessly.

As Wikipedia states:
“The WiGig specification allows devices to communicate without wires at multi-gigabit speeds. It enables high performance wireless data, display and audio applications that supplement the capabilities of previous wireless LAN devices. WiGig tri-band enabled devices, which operate in the 2.4, 5 and 60 GHz bands, deliver data transfer rates up to 7 Gbit/s, about as fast as an 8-band 802.11ac transmission, and more than 11 times faster than the highest 802.11n rate, while maintaining compatibility with existing Wi-Fi devices. The 60 GHz signal cannot typically penetrate walls but can propagate off reflections from walls, ceilings, floors and objects using beamforming built into the WiGig system. When roaming away from the main room, the protocol can switch to make use of the other lower bands at a much lower rate, both of which can propagate through walls.”

Watch for 802.11ad devices that are on the market now from Netgear and TP-Link.
