It's a pr stunt for now but not that far off. 20 years after Paulraj invented MIMO, a company founded by his Stanford colleague Andrea Goldsmith is using 8 antenna MIMO to show the way to 10 gigabits on WiFi. Broadcom is promising similar. The real world results of "1.3 gigabit 802.11ac" so far are 400-500 megabits and the early results of "10 gigabit" will probably suffer similarly. But in 2-3 years, some homes will have effective WiFi speeds in the gigabits.

Paul Space Time book 220x287These speeds are based on 160 MHz of spectrum, only possible if few neighbors are using the band. 8 antennas will provide 8 separate streams in some locations but little more than 1 stream in others. MIMO separates signals by slight differences in reflection. That has the surprising result that the worst performance is when you have perfect line of site. Hakan Ericsson of Ericsson explained to me that MIMO gains would be very small in much of rural Australia because the terrain is flat.

IEEE has a very active standards group, 802.11ax, working on multi-gigabit WiFi.  There's a wealth of information at the .11ax page. IEEE has a free mailing list that lets you track what's going on.

Sebastian Anthony has a good introduction to .11ax at Netflix and Comcast are using 15 megabits down for 4K. 15 channels fit in 300 megabits. (Anthony @mrseb is about to launch Ars Technica in the U.K. If Ars in the U.K. matches the quality of Ars U.S., it will instantly become one of the top tech pubs there.)

Sebastian reminds that even "uses like streaming 4K video, still fall way short of these multi-gigabit speeds." 

Here's Quantenna's pr and also the announcement they've raised another $22M. 

Quantenna Demonstrates 10G Wi-Fi Platform at CES 2015

World’s first true 8x8 MIMO for world’s fastest Wi-Fi, highest capacity and broadest reach to support Wi-Fi client explosion

LAS VEGAS – January 5, 2015 – CES -- Quantenna Communications, Inc.. the leader in ultra-high performance Wi-Fi, today announced that it is demonstrating its 10G Wi-Fi™ platform at CES 2015, the world’s first system to fully implement full 802.11ac Wave 2 functionality including fully configurable up to 8x8 MIMO, Multi-User MIMO (MU-MIMO) and 160Mhz channel support with the ability to deliver up to 10Gbps in total Wi-Fi network capacity.

As Wi-Fi usage continues to explode, True 8x8™ provides the flexibility and scalability to meet the growing demand for Wi-Fi capacity. “Since the announcement of our 10G Wi-Fi platform technology development, we have been overwhelmed with the positive feedback from our customers and service providers. They immediately saw the advantages a true 8x8 MIMO system can deliver in their future home gateways. Today we are excited to be demonstrating the platform,” said Dr. Sam Heidari, Quantenna CEO.

With True 8x8™, the 10G Wi-Fi platform delivers the fastest total throughput, highest total capacity, maximum possible reliability and highest possible coverage to all Wi-Fi clients. Supporting MU-MIMO, the 10G Wi-Fi platform delivers the maximum possible capacity within the minimum amount of spectrum. Even Single User MIMO (SU-MIMO) 1x1 and 2x2 client performance is improved, ensuring that the millions of users of currently shipping mainstream smart phones, tablets and notebook PC’s will enjoy an improved Wi-Fi experience. End consumers will experience faster, more reliable video streaming, faster downloads and uploads and overall better performance even at extremely long distances when connected to their True 8x8™ enabled gateway.

With 10G Wi-Fi™ unmatched capacity, reliability and coverage both inside and outside the home, service providers can transform residential gateways into hotspots enabling service providers to enhance their subscribers experience and increase their access to Wi-Fi. Demand on Wi-Fi networks is growing exponentially year on year.

Parks Associates data shows the number of US broadband households with three or more connected devices has doubled from 9 percent in 1Q12 to 18 percent in 3Q13. Furthermore, the number of Internet-enabled devices in the home is increasing and is expected to reach 25 per home in 2017 (source: OECD). Simultaneously, half of the Internet traffic is expected to run through Wi-Fi by 2018, according to the 2014 Cisco VNI report. As broadband access data rates increase and with increasing dependence on Wi-Fi for all aspects of people’s lives, Wi-Fi capacity and performance must be optimized within the limited available spectrum.

The scalable 10G Wi-Fi platform with its world’s first True 8x8 is designed to meet the on-going explosion in the number of Wi-Fi clients while limiting interference and optimizing overall spectrum usage efficiency and maximizing so-called “geo-capacity” across entire neighborhoods and apartment buildings. “The growth in the number of connected devices in a home network is continuing and congestion in home networks is becoming a real problem affecting the user experience,” said Tejas Mehta, research analyst, Parks Associates. “As device manufacturers, technology partners, and service providers all search for solutions to address the congestion problem, Multi-User MIMO (MU-MIMO) is emerging as a strong candidate to address this problem. A significant number of connected devices in a home network are mobile devices such as smartphones and tablets with one or two spatial streams, making MU-MIMO a particularly attractive proposition.”

“Wi-Fi usage continues to explode, presenting challenges on how best to scale the gateway to meet those requirements. We were the first to address this with our unique True 4x4™ starting with 802.11n solution and we continued this leadership with the world’s first 4x4 802.11ac solution. We are extending our leadership with our True 8x8™ platform.

Others are promising to solve the problem the wrong way by simply stacking more radios on top of each other. So-called ‘dual radio’ or ‘tri-band’ solutions actually compound the problem as these extra radios compete with each other for spectrum and induce additional interference reducing overall capacity,” added Dr. Heidari. “We are implementing the right solution with higher order MIMO configurations including 8x8 in one baseband. We have established ourselves as the ultra-high performance Wi-Fi leader and we have raised the bar yet again with our 10G Wi-Fi platform. We will continue to deliver on our mission to provide the highest performance and most reliable Wi-Fi experience in the world.”
