how the data rides on a wave
1.A stream of data is organized into manageble chunks
2.Perception changed from stream of bytes to stream of bits
3.Bits are grouped in symbols
4.~1200 symbols are passed through a serial to parallel converter
5.each parallel line is connected to an IFFT line of 2048 lines
6.output is a matrix representation of the input in the frequency domain
7.this is passed to D/A converter and raised by a dash? frequency
8.the outgoing wave contains the data
exactly the opposite happens on the receiving side
