OFDM

OFDM stands for Orthogonal Frequency Division Multiplexing. It's a type of technology used to send signals or data over a network or the internet. It works by grouping data into small pieces, and then sending each piece on a different frequency. All the different frequencies are then combined together so they can be sent in one signal. It's a bit like when someone talks to you in the same room, but they whisper each word in a different part of the room; when you listen to what they said, it all sounds like one normal conversation even though each individual word was whispered in a different spot. OFDM does the same thing with data, allowing many signals to be sent at once in the same signal.
