During the past year, various members of the wireless ecosystem -- from industry advocacy groups to standards bodies to suppliers -- have been working tirelessly on new standards that will define Wi-Fi for the better part of the next decade. Now, with nearly unanimous buy-in to both 11ac and the 60GHz standard, the industry is well on its way to a quantum leap in Wi-Fi performance.
Of course, like any standard, these technology advances will take several quarters to make their way to market. Unfortunately, the uses that necessitated these new standards, such as the exponential growth of tablets and smartphones and uncompressed streaming video, will not stagnate as enterprises wait to upgrade their infrastructure.

In the meantime, there is an existing technology solution -- beamforming -- already available in access points and end devices that dramatically improves Wi-Fi performance, smoothing the path to 11ac and beyond. Beamforming, a non-proprietary technology, is not only compatible with the emerging 11ac products, but also part of the new standard's specification, meaning any immediate investments in technology will not be nullified as 60GHz and 11ac infiltrate the enterprise.
Beamforming is a non-proprietary wireless technology that can be integrated across a range of devices, from access points to laptops to smartphones. It greatly improves wireless performance, providing a 2X-3X improvement over previous wireless solutions.
Beamforming enables this performance with an innovative approach to how wireless devices connect. In previous generations, wireless was like a lightbulb, with a hotspot or access point "radiating" wireless indiscriminately in a set area. Beamforming is like a laser -- the hub recognizes the device that needs wireless and focuses the wireless directly where it's needed -- whether it's one device or 20. Because of this novel approach, wireless can also beam around corners and through walls, eliminating previous performance obstacles encountered in large enterprise spaces.
In an enterprise environment, not all devices on the network need beamforming to reap the benefits of the technology. An access point with implicit beamforming technology can still directly "beamform" to an end device without it, enabling better performance. Inversely, a tablet with beamforming technology can better leverage the wireless signal from an access point that does not have beamforming.
Devices leveraging beamforming, from access points to end devices, have been shipping in volume since November 2010. As enterprise IT departments upgrade their infrastructure and invest in new equipment for employees, it will be beneficial to work with technology suppliers to ensure new investments boast beamforming technology.
