How WiGig, a new standard, could fill the gap
This year’s Mobile World Congress in Barcelona (MWC 2013) provided an opportunity to foresee the future of wireless technology, not just for mobile phones but for all connected devices.
As this picture confirms, the average computer invariably needs to be connected to numerous other devices in order to perform its multiple daily tasks. Increasingly, the converged world is blurring what content and applications can be obtained from what device; films are available on tablets, Internet on the television and video conferencing on PCs. For those of you who embrace these new opportunities there is invariably that moment when you need to swap from one device to another or share content simultaneously between two devices; at this point you’re scrambling to find the right connector, adaptor or cable. In the very near future this situation may be a thing of the past. Connecting the space between devices and enabling easy and rapid sharing of data, video and connectivity became a step closer to reality over the last three months with the unification of the WiGig and Wi-Fi Alliances.
For the past five years, the Wireless Gigabyte Alliance (WiGig) has been developing a new wireless standard that operates at 60 GHz and can deliver data rates up to 7 Gigabits per second – approximately 10 times the speed of the fastest Wi-Fi technology currently available. One of the major proponents behind this technology is Intel which envisions a future of all your devices cleverly synchronizing masses of data, and without effort on your part. High definition video and images will be instantaneously sharable between PCs, televisions, tablets and other consumer electronic devices. Another proponent, Panasonic, has already demonstrated their prototype WiGig-enabled SD card, showing how it will only take one minute to wirelessly transfer a full DVD video from a wireless controller to a display mounted within a car.
The memorandum of understanding between the Wi-Fi Alliance and WiGig Alliance comes shortly after the IEEE has approved the WiGig standard as 802.11ad, thereby encompassing it within the Wi-Fi family. It is hoped that this unification and standardization will help drive the mass adoption that the Alliance has been aiming to achieve by changing the “perspective of end-users that it was two different standards and two different brands” according to Dr. Ali Sadri, President of the WiGig Alliance, when I interviewed him at MWC 2013 in March.
With multiple manufacturers planning to install WiGig technology into devices across a broad spectrum of consumer electronics products, this will not only increase the speed of massive data and video file transfer but also – through improved and efficient protocol adoption layers (PALS) – facilitate enhanced applications for HDTVs and other consumer electronic devices in the future.
Another potential benefit of WiGig could be seen in large venues, such as shopping malls, sports stadiums, hotels or conference facilities, where high speed, ubiquitous coverage for high volumes of users is difficult to provide using current Wi-Fi technology. The 802.11 ad / WiGig standard will allow five access points instead of the single Wi-Fi access point currently in existence, thereby allowing approximately 50 times more capacity. In addition, the range is controlled utilizing sophisticated beam-forming antennas with a footprint of about 10 m so that overlapping footprints can be created every 10 m or so, enabling users to connect and shift seamlessly between access points while maintaining a high speed data link connection.
Needless to say, key players in the semiconductor industry such as Intel, Broadcom and Samsung will be aggressively marketing this technology. They may not have to push too hard because the huge appeal of being able to wirelessly connect devices and seamlessly share ever increasing amounts of content is bound to drive rapid consumer adoption. Finally a solution to all those trailing wires and connections!
