PROJECT DESCRIPTION

TRENDS AND OPPORTUNITIES

The industry faces a challenge in meeting the requirements of new emerging applications demanding end-to-end Quality of Service (E2E QoS) and reduced latency. Wi-Fi systems currently lack compatibility with new QoS protocols.

L4S (Low Latency Low Loss Scalable Throughput) technology optimizes throughput, minimizes latency, and reduces packet loss. Integral to Low Latency DOCSIS specifications, L4S is increasingly adopted in diverse networking technologies.

The project aims to enhance Wi-Fi systems’ compatibility with new QoS protocols, addressing the need for E2E low latency. This will support applications like Extended Reality (XR) and enable a new tier of services with low latency and high bandwidth.

BUSINESS & MARKET BENEFITS

This project opens avenues to support emerging applications, especially those requiring end-to-end low latency, and introduces an enhanced performance tier of services.

Moreover, the project aims to establish guidelines for implementing L4S over Wi-Fi, ensuring alignment with future Wi-Fi standards through collaboration with IEEE 802.11bn.

  • Define the industry guidelines on how to support Low Latency Service (L4S) over Wi-Fi
  • Identify requirements and address gaps in Wi-Fi to support L4S
  • Investigate L4S in industry bodies, analyze its implications on Wi-Fi signaling, and develop implementation guidelines for widespread stakeholder adoption
  • Provide comprehensive documentation outlining the requirements and solutions.

EXPECTED OUTCOMES

Define clear industry guidelines for enabling Low Latency, Low Loss, Scalable Throughput (L4S) over Wi-Fi and outline the requirements needed to close current technology gaps.

Key Deliverables

Establish end-to-end interoperability, achieve L4S compliance in home CPEs by 2026–2027, and demonstrate performance with one to two applications.

Provide a performance test framework covering both Wi-Fi and integrated Wi-Fi–access network scenarios.

Advance application-level L4S compliance from 2027 onward through coordinated engagement with application providers and OS vendors to drive adoption and ecosystem readiness.
