WIRELESS RANGING WITH BW320 BASED ON EHT FORMAT - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240049157 titled 'WIRELESS RANGING WITH BW320 BASED ON EHT FORMAT
Simplified Explanation
The present invention relates to systems, apparatus, and methods for wireless ranging procedures using eht frames that support large bandwidth transmission. The ranging specifications are expanded for the eht frame format to support bw320 ranging with improved performance and accuracy. The invention also supports high-bandwidth bw320 and bw240 wireless ranging using an eht frame format and supports 802.11az ranging using a high efficiency (he) for 802.11be devices. The invention includes features such as long training field (ltf) repetition features and security features for eht-ltfs, as well as signaling of preamble puncturing patterns for 320 MHz physical layer protocol data units (ppdus) carried in the u-sig field and in trigger frames to improve spectrum efficiency and reduce interference.
