Quantenna develops first 802.11ac 10G Wave
3 Wi-Fi product line and Freescale takes
advantage
Steve Taranovich - October 24, 2015
Quantenna Communications has developed the industry’s first 10G Wave 3 Wi-Fi product family. The
products are built on Quantenna’s True 8×8 QSR10G Wi-Fi platform with multi-user MIMO (MUMIMO) technology for home wireless access points and residential gateways. Quantenna’s design
has up-to-12-streams 10G Wave 3 in their product family which enables higher Wi-Fi performance,
reliability and capacity for high-density environments, and is able to address both the service
provider and retail market segments.
The best Wi-Fi radios in the market today, stack two 4×4 MIMO order radios for 5GHz and 2.4GHz
to achieve a high-density wireless network design, have only half the spectral efficiency as True 8×8
used in the latest Quantenna design. In a two 4×4 stacked radio inside a single router, each radio
will have to operate on a different channel giving the overall design half the spectral efficiency of
Quantenna’s True 8×8 MIMO order, will use more power, cost more due to the need for additional
RF filters and cannot be frequency agile. See Figure 1.
Figure 1: Dual 4×4 radios need filters because each 5GHz radio operates on a separate
channel. The addition of filters prevents Adjacent Channel Interference (ACI). Radio 1 is
restricted by low pass hardware filters and Radio 2 is restricted by high pass hardware
filters. This radio has no frequency agility capability; the filters fix channel operation.

In Figure 1 we can see in the bottom row the maximum conducted power set by the FCC for each
radio. So, for example, in the 5.15GHz to 5.25 GHz band radio, the maximum power can be set to
1000mW. The total conducted power for a 4×4 radio will be 2000mW and the Power Amplifiers
(PAs) are dissipating a great deal of power to provide this total power. Only one of the 4×4 radios is
used for beamforming for any particular client. The two 4×4 radios are distinct and do not work
together.
In contrast, the True 8×8 MIMO design is fully compliant to IEEE 802.11ac which defines 8×8 and
not dual radio stacking. Quantenna’s design has only one radio and is the most spectrally efficient
design and it can use up to 8 antennas for beamforming, avoids costly RF filters and is capable of
tuning to any channel. The total conducted power is only 1000mW.
10G Wave 3 is a revolutionary new way for Wi-Fi networks to operate. As Wi-Fi usage continues to
ramp at a steep pace, 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 8×8 MIMO configuration for 5GHz networks with a 4×4 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), 1×1 and 2×2
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. See
Figure 2.

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 8×8 MUMIMO 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.
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.

Freescale introduces the industry’s first 10 Gbps Wi-Fi enabled Home Gateway Solution
Freescale Semiconductor was quick to use the Quantenna IC and is driving next-generation, multi-
gigabit broadband access toward mainstream adoption with the industry’s first 10 Gbps Internet
plus 10 Gbps Wi-Fi enabled home gateway solution.
Freescale developed its new QorIQ LS1043A residential gateway in collaboration with Quantenna
Communications. Coupled with open, Linux-based security, video streaming and networking
applications, the platform enables dramatic boosts in bandwidth, throughput and quality of service.
The new Freescale solution leverages its quad-core QorIQ LS1043A processor based on 64-bit
ARMv8 technology, together with Quantenna’s QSR10G 10G Wave 3 802.11ac Wi-Fi product family.
This latest Quantenna product family can support up to 12 streams. The reference solution also
features a 10 Gbps copper or fiber WAN connection enabled by the QorIQ LS1043A processor’s 10G
Ethernet port.
