This requires some form of multiplexing of the two messages for transmission down a common communications path, e.g. medium, circuit or channel. Early developments resulted in the concept of frequency ...

The multiplexing principle originates from the ... For the lowest-order transverse-electric (TE 1) mode of a PPWG, the frequency-dependent propagation constant is given by 24 Numerical simulations ...

In actuality, a feature called orthogonal frequency division multiplexing (OFDM) does exist in older versions of Wi-Fi, but it was only for single transmissions. Wi-Fi 6 access points (APs ...
