Richard van Nee, Senior Director, Qualcomm International Technologies
An overview is given of physical layer developments in WiFi that started 26 years ago with single-carrier CCK modulation while the latest WiFi-7 standard uses MIMO-OFDM with new features such as 320MHz and 4K-QAM. Besides data transmission, there is a growing interest to use WiFi for different applications such as positioning and sensing which are also addressed in this talk.
