Is 10 Gigabit Wi-Fi Networking Coming Next Year?

Quantenna Communications is developing the world's first 10 Gigabit (10G) Wi-Fi chipset for a new generation of access points. The company is using a "novel" architecture that will enable MIMO configurations up to 8x8, speeds up to 10 Gigabits per second, and universal support for Multi-User MIMO (MU-MIMO) clients.

The typical Wi-Fi device on today's market includes a 3x3 setup, which means the device is capable of sending and receiving three separate streams of data simultaneously. These can achieve throughput speeds of up to 1.3 Gbps on the 5 GHz band, whereas Quantenna's existing QSR1000 4x4 MIMO chipset can push that Wireless AC speed on the 5 GHz band up to 1.7 Gbps.

"Quantenna was the first to deliver 4x4 chipsets for the 802.11n and 802.11ac Wi-Fi standards, and the first to support MU-MIMO, an ingenious technology for transmitting data to multiple devices at once," states the PC. "With those innovations and others such as adaptive beamforming and channel monitoring and optimization, Quantenna's Wi-Fi reaches farther and transmits faster and more reliably than any other."

MU-MIMO is an advanced version of MIMO that can transmit data to multiple users at the same time by utilizing the antennas on a number of independent access points. In contrast, MIMO uses a single multi-antenna transmitter to communicate with a single multi-antenna receiver. The drawback to MU-MIMO is that it can only be used in the downstream direction as stated in the 802.11ac Wave 2 specification.

The company points out that Asus is currently using Quantenna's 802.11ac chipset to build the world's fastest consumer router. STMicro is building Quantenna Wi-Fi into a wide range of System-on-Chip (SOC) offerings while Texas Instruments is incorporating Quantenna technology into its reference platform for enterprise.

"We've made 4x4 MU-MIMO a reality, but we can't stop there," said Dr. Sam Heidari, CEO, Quantenna Communications. "Wi-Fi is no longer a convenience. People expect it to 'just work' even with demanding applications like HD video streaming. With Quantenna's 10G Wi-Fi, they'll always get the performance they expect—even as their expectations continue to rise."

Quantenna plans to make the first 10G Wi-Fi chipsets available in 2015, including support for MIMO configurations up to 8x8.

    It's all well and good, but the fastest wireless AC card (not usb stick) that you can get for a laptop only supports 2x2 for 866 mbps (Intel AC 7260). It's been out for a year now with no 3x3 yet.

    Show me a 3x3 AC card for laptops, and then I will start to believe that 8x8 showing up in the next 5 years is a possibility.

    This might enable 1 Gbps under ideal conditions.

    How about standard 10gbe on wire first
