Real time boost for WiFi
The WiFi Alliance has launched a certification program to provide a standardized approach to traffic prioritization for real-time applications.
WiFi Quality of Service (QoS) Management builds on the widely adopted WiFi Certified WMM (wireless mulitmedia) to deliver a consistent, end-to-end approach to Quality of Service (QoS) treatment across WiFi and wirednetworks. The program introduces two new technologies that allow WiFi devices, applications, and network managers to prioritize traffic flows by establishing a standards-based approach to QoS mirroring and by aligning with IETF recommendations for QoS mapping between Internet Protocol (IP) and IEEE 802.11.
Residential, enterprise, and public networks all benefit from from the QoS Management, particularly when using applications requiring low latency and low jitter, including videoconferencing, interactive gaming, AR/VR, industrial IoT, and healthcare monitoring. It is also critical for industrial networks.
The QoS Management provides standardized mechanisms that allow client applications to request QoS treatment, and for network managers to implement QoS policies. These mechanisms allow user devices and access points to select differentiated prioritization depending on the application. The result is robust service delivery and higher quality WiFi, including better experiences with real-time and immersive applications, and reduced latency and jitter when online gaming or accessing interactive cloud and edge services.
“Today’s Wi-Fi networks carry a demanding amount of real-time data applications that require discerning treatment to deliver high quality experiences,” said Edgar Figueroa, president and CEO, of the WiFi Alliance. “WiFi Alliance is introducing Wi-Fi QoS Management as a new way to manage WiFi traffic and ensure end-user expectations for superior performance continue to be met.”
“WiFi QoS Management provides the tools to empower application developers and vendors of mobile and gaming devices to manage bidirectional traffic flows on home and enterprise Wi-Fi networks to enable the required quality of service for all applications,” said Thomas Derham, Principal Scientist, Wireless Communications and Connectivity Division at Broadcom and contributor to the task group. “It also provides essential tools to enable network administrators to manage QoS at a system level. WiFi QoS Management combined with WiFi 6E will enable enterprises, operators, and users to enjoy latency sensitive applications such as live video streaming, gaming, augmented and virtual reality, even in spectrally congested and challenging environments.”
The QoS management uses Mirrored Stream Classification Service (MSCS) that enables a client device to request the access point to apply specific QoS treatment of downlink IP data flows using QoS mirroring, while the Differentiated Service Code Point (DSCP) mapping aligns QoS treatment across WiFi and wired networks and also enables network managers to configure specific QoS policies.
“WiFi is an essential enabler for today’s digital economy and provides the backbone for multiple real-time applications with simultaneous usage of voice, video and data. On Semiconductor has been a strong supporter of Wi-Fi Alliance’s certification programs to optimize Wi-Fi network performance. As such, QoS is a cornerstone of our technology platforms with built-in functionality to differentiate between traffic flows, giving precedence to high priority traffic and ensuring airtime fairness across both flow types and devices. It is all about improving user experience, and reducing latency, packet loss, and jitter,” said Irvind Ghai, vice president of marketing, Wireless Connectivity and Signal Process Division at On Semiconductor.
Member companies providing interoperability test bed devices that are among the first Wi-Fi CERTIFIED QoS Management products include Broadcom, Intel, and Qualcomm Technologies.
