Use cases are at the heart of PREDICT-6G. They are the way for our research and use case providers to experiment, validate and demonstrate how PREDICT-6G technologies enable a reliable, predictable and time-engineered 6G network. Claudio Casetti, Full Professor at Politecnico di Torino and a researcher in the PREDICT-6G consortium led the “Target Wake Time” demo.

This demonstration shows the evolution of Wi-Fi networks with the introduction of Target Wake Time (TWT), a feature that transforms the way devices communicate within a network. Traditionally, Wi-Fi networks were based on CSMACA principles, which allowed efficient collision resolution but introduced randomness in channel access and transmission timing. The demonstration delves into how TWT, initially introduced in 802.11 AH and later integrated into Wi-Fi 6 (802.11 AX), addresses these challenges. 

Using simulations with 8 strategically spaced stations, the demonstration compares TWT-enabled communication with standard Wi-Fi, highlighting TWT’s deterministic latency and significant energy savings.
