Modulation is one of the key components relating to how your network traffic is translated into a format that is traversable over  any network infrastructure either wired or (and the topic of this post) wireless connections.  Modulation sits at the lowest level of the OSI model, the Physical Layer (Layer 1).  Think of modulation in a real world example, as a translator. Preparing the data received from the higher layers of the OSI model into a more accessible and easily transmitted format across the network and more specifically relating to Wi-Fi, across the antennas transmitters/receiver hardware.   Wi-Fi modulation has seen many changes across its evolution from it's first initial standard in 1997 and is still changing even now with the currently in development standard Wi-Fi 7 (11be) which we will also cover in terms of it's changes to modulation.   There is three main ways that modulation takes place in Wi-Fi, and they're as follows, Binary Phase Shift Key (BPSK),
