Evaluating the Impact of Channel Feedback Quantization and Grouping in IEEE 802.11 MIMO Wi-Fi Networks

Year: 2024

Type: article

Abstract: In this letter, we shed light on the impact of multiple-input, multiple-output (MIMO) beamforming feedback quantization and orthogonal frequency-division multiplexing (OFDM) sub-channel grouping on communication performance, for IEEE 802.11ac/ax Wi-Fi networks. We performed an extensive data collection campaign with commercial Wi-Fi devices deployed in different propagation environments considering several network configurations. Our objective is to provide a benchmark for research on efficient feedback compression mechanisms and to enable further analysis. As such, we pledge to share the datasets we collected and the emulation framework we developed.
