Wi-Fi 7 PHY/MAC deep dive course outline (duration 1-2 days)
Wi-Fi 7 is here and it is by far the most complex Wi-Fi standard ever developed. It also means that vendors and service providers need to make additional effort in understanding the details of the standard. To that end we offer our Wi-Fi 7 MAC/PHY deep dive delivered by our Chief Trainer, Dr Srikanth Subramanian.
