LOW LATENCY LOW LOSS SCALABLE THROUGHPUT (L4S)

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 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.

EXPECTED DELIVERABLES

• 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
• Establish communication with IEEE 802.11bn (Wi-Fi 8) to convey these requirements
