Operators and Enterprises can use QoS as a powerful market differentiator to attract and retain customers, such as business travelers who need reliable, high-performance Wi-Fi in airports. Enterprises need Wi-Fi networks that can provide the right QoS for each application, such as prioritizing HD video collaboration sessions over email and file transfers. And home Wi-Fi networks need to balance a variety of bandwidth-intensive, latency-sensitive applications, including multiplayer gaming, 4K streaming and remote work videoconferencing — often all simultaneously.
E2E QoS Improvement: Optimizing QoS Over Wi-Fi report explores how network operators can meet the unique QoS requirements for a wide variety of use cases and deployments, including gaming, residential broadband, live 4K video, enterprise, airports, stadiums and more.
As its name implies, end-to-end (E2E) QoS includes the application, such as cloud gaming or streaming video, Wi-Fi network elements such as access points (APs) and Wi-Fi client devices (like mobile phones and laptops). The E2E concept is about providing both visibility into and control over the user experience by leveraging QoS mechanisms at each step of a packet’s journey across the Wi-Fi ecosystem.
The paper discusses the use of ITU-T SG12 recommendations and corresponding tools to access objective mean opinion scores (MOS) the QoS streams during the trials with outcomes from the trials.
Additional future, WBA work includes expanding network topology to incorporate Wi-Fi mesh (Wi-Fi Alliance EasyMesh), extending QoS management to non-Wi-Fi links for E2E QoS and integrating new QoS management mechanisms from ongoing work in the IEEE802.11 Working Group and/or Wi-Fi Alliance QoS Management TG, and/or IETF.
