Fast Net News - Quantenna's Remarkable 10 Gig WiFi

Speeds through a wall go down severely with any WiFi, but throughput even through walls should be excellent. MU-MIMO - dedicating the 8-12 streams 1, 2 or 4 to an individual device with beamforming - should give each of the devices excellent throughput. Quantenna has distributed samples but production quantities are in the future.

If you have no neighbors and completely uncontested WiFi frequencies, you will sometimes be able to measure a nominal 9 or 10 gigabit WiFi from Quantenna and Freescale's new chips. You'll need an ideal location, with just enough interference to bounce the 12 separate signals but not enough to significantly slow anything down. 160 MHz is about the entire bandwidth of the combined AT&T and Verizon LTE networks, far more than will be available to most of us in most places. So the many MU-MIMO connections will have more practical impact for most of us. In addition, they are squeezing a heck of a lot of data in, going to a 1024 QAM constellation, needing extraordinary analog circuitry and minimal interference.

Twenty years ago, Arogyaswami Paulraj discovered using more antennas could multiply the throughput of a wireless network. That day it rained on the Stanford campus and he moved his multi-transmitter experiments indoors. Because the transmitters would be close together, he expected poor results. To his surprise, the separate signals came in clearly. He had invented MIMO.

A few days later Paul realized that the signals had bounced off the walls in slightly different patterns and this would be a practical way to multiply the throughput in a given bandwidth. Within a few years, Paul realized this could be extended to dozens and even hundreds of antennas, but it took nearly a decade before the first practical devices.

Quantenna, founded by Paul's Stanford colleague Andrea Goldsmith, was first to market with 4x4 MIMO WiFi. Their chips were instantly gobbled up by cablecos and telcos wanting to distribute video throughout the house. Chips that can keep up with 8 antennas are state of the art so I expect it will take a while to get yields high enough to bring prices down.

I'm sure Sam Heidari and teamnare working very hard to prove me wrong and enter mass production. Update Sept 15 Jeremy Hyatt for Quantenna writes me things are going well enough they expect to enter mass production in the next 90-120 days. They also wrote "The chipset supports a unique architecture that adapts its MIMO configuration for 5GHz and 2.4GHz based on client usage so that, for example, an access point originally configured as 6x6 5GHz and 4x4 2.4GHz can adapt to 8x8 5GHz and 2x2 2.4GHz when there are more 5GHz than 2.4GHz client devices."

Quantenna Announces World’s First 802.11ac 10G Wave 3 Wi-Fi Product Line

World’s Fastest 10Gbps Family for Wi-Fi Access Points Features True 8x8™ and MIMO for 5GHz and 2.4GHzto Manage High-Density Wireless Networks

FREMONT, Calif., Sept. 9, 2015 – IBC2015 – Quantenna Communications, the leader in ultra-high performance Wi-Fi, today announced the availability of the industry’s first 10G Wave 3 Wi-Fi product family. The products are built on Quantenna’s True 8x8™ QSR10G Wi-Fi platform with multi-user MIMO (MU-MIMO) technology for home wireless access points and residential gateways. Quantenna’s up-to-12-streams 10G Wave 3 product family delivers unprecedented Wi-Fi performance, reliability and capacity for high-density environments, and can address both the service provider and retail market segments.

10G Wave 3 is a revolutionary new way for Wi-Fi networks to operate. As Wi-Fi usage continues to explode, 10G Wave 3 provides the flexibility and scalability to meet the growing demand for Wi-Fi capacity. Quantenna is the first and only company implementing 10G Wave 3 to support speeds up to 10Gbps. This milestone speed benchmark for Wi-Fi is attained by combining the industry’s first True 8x8™ MIMO configuration for 5GHz networks with a 4x4 MIMO configuration on 2.4GHz networks for a combined 12-stream configuration.

Quantenna’s 10G Wave 3 platform delivers the maximum capacity within the minimum spectrum so that more streams can be simultaneously transmitted with improved range and reliability. This means that 802.11 Wi-Fi access points or gateways using Quantenna’s 10G Wave 3 product family can support more clients, each running more efficiently for such demanding applications as real-time video, OTT video, voice, IoT and other services. Even single-user MIMO (SU-MIMO), 1x1 and 2x2 client performance is vastly improved, ensuring that the millions of currently shipping mainstream smart phones, tablets and notebook PCs will also benefit from an improved Wi-Fi experience.

According to ABI Research, over 1.5 billion products with 802.11ac will ship worldwide by the end of 2015. “Shipments of devices which support the 802.11ac standard grew significantly in 2014 and 2015," said ABI Research Director Philip Solis. "Rising demand for home access points that can manage and support the dozens of Wi-Fi devices is generating an immense opportunity for leading component suppliers, such as Quantenna, who are early to market with innovative solutions.”

The QSR10G Wave 3 product family also supports a unique adaptive MIMO architecture. This enables 10G Wave 3 access points to maximize overall network performance, delivering the best possible capacity across all client devices. This is important as the mix of legacy and new client devices are changing, as end consumers adopt more devices with 802.11ac.

“In Wi-Fi access points more antennas are always better, but 10G Wave 3 is not just about 8x8 MU-MIMO and faster speeds. It’s about making better use of network and airtime efficiency to support the growing number of connected devices, services and applications,” said Dr. Sam Heidari, Quantenna CEO.“After pioneering the Wi-Fi industry with 4x4 MIMO, we’ve gained a deep understanding of real-world channel behavior in crowded environments. These insights have led to the creation of 10G Wave 3 and the world’s first 8x8 MIMO, which are poised to revolutionize the Wi-Fi experience.”

In addition, 10G Wave 3 allows access points to support up to four simultaneous Multi-User MIMO (MU-MIMO) clients per group. This means more total system capacity and aggregate

throughput can be supported - a trend that continues unabated, as the number of clients increases per household over time. More consumers will experience the fastest, most reliable video streaming experience, faster downloads and uploads, and better performance even at extremely long distances, in challenging high-density Wi-Fi home environments and outdoor applications like Wi-Fi hotspots.

10 gig requires a remarkable 160 MHz+ but it makes a great headline. With this 8x8 chipset, realistic speed will head to a gigabit and higher, in a room with just the right walls for the MIMO to work. Speeds through a wall go down severely with any WiFi, but throughput even through walls should be excellent. MU-MIMO - dedicating the 8-12 streams 1, 2 or 4 to an individual device with beamforming - should give each of the devices excellent throughput. Quantenna has distributed samples but production quantities are in the future.
