Quantenna announces first 802.11ax Wi-Fi access point chip set
The QSR10G-AX will support 12 total streams: 8 streams in the 5 GHz band and 4 streams in the 2.4 GHz band. The chip set adds support for downlink and uplink OFDMA (Orthogonal Frequency-Division Multiple Access), providing superior network efficiency in dense environments as well as high uplink performance. OFDMA dedicates different sub-carriers for individual client devices. This allows multiple devices to be simultaneously served.
QSR10G-AX is designed to enable a very easy and fast transition for existing QSR10G customers. The QSR10G-AX chipset is pin-to-pin compatible with QSR10G, Quantenna’s Wave 3 12-stream dual-band 802.11ac and 802.11n access points. As a result, customers designing with QSR10G will be able to drop in the new QSR10G-AX.
“Quantenna has once again demonstrated its pioneering innovation and leadership in the Wi-Fi market with the announcement of the QSR10G-AX,” said Andrea Goldsmith, Stephen Harris Professor of Electrical Engineering at Stanford University. “This technology, which incorporates the 802.11ax protocol, is a leap forward for Wi-Fi through the access technique of OFDMA. The more flexible, efficient, and adaptive use of the Wi-Fi spectrum enabled by OFDMA will increase the data rates of the QSR10G-AX over current products, while also supporting in a reliable and scalable manner the growth of client devices in dense deployments. The transformative technology of the QSR10G-AX will be beneficial for high-performance Wi-Fi devices as well as emerging applications in the IoT.”
As Wi-Fi usage continues to grow, the Wi-Fi 802.11 IEEE standard evolves to cope with the augmented complexity of Wi-Fi networks. 802.11ax was designed with the goal of increasing Wi-Fi networks efficiency in dense deployments such as multi-dwelling units. In addition, it improves Wi-Fi network capacity and performance in terms of its ability to support more simultaneous clients. Lastly, 802.11ax provides increased speed over 802.11ac. All of these improvements are helpful for businesses, public venues, and also in homes where the number of clients continues to grow due to the proliferation of mobile and Internet of Things devices.
Key features and benefits of the QSR10G-AX include:
- Integrated AP chipset for dual-band (5 GHz and 2.4 GHz), dual concurrent operation and management;
- Pin-to-pin compatibility with QSR10G;
- 802.11ax draft 1.0 compliant;
- 12-stream operation;
- Supports rich set of interfaces to external hosts such as PCIe Gen3/Gen2, RXAUI, RGMII, and others;
- Supports 2.4 GHz coexistence interface;
- Enable full offload for external host;
- Cloud managed.
The QSR10G-AX is expected to sample to early access partners in the early part of 2017.
