Wi-Fi 7 Static Preamble Puncturing : Throughput in a mixed clients scenario
.webp)
Wi-Fi 7 Static Preamble Puncturing Introduction Among a host of features like MLO, 4K QAM, and 320 MHz, Wi-Fi 7 also introduces Static Preamble Puncturing that can be used for a variety of reasons. Preamble puncturing was initially introduced in 802.11ax mainly for the MU transmission (OFDMA frames). However, in 802.11be aka Wi-Fi 7, this feature is introduced for SU frames and has been made mandatory to be supported by clients in the 6 GHz band (static preamble puncturing only with dynamic puncturing support being optional). In this blog, we aim to discuss static puncturing and its impact on throughput in scenarios involving mixed clients for SU frames (Non-OFDMA). Use cases Congested Environment: When introduced in 802.11ax, preamble puncturing aimed to improve efficiency in congested network scenarios by allowing transmissions even if part of the spectrum is unavailable. Radar Detection: Preamble puncturing allows devices to avoid switching channels when radar signals ...
