processing. The basic routines that need to be implemented are modulation, demodulation and

channel monitoring (carrier sensing).

For ease of cross-reference, a global context, called SDR_CONTEXT, is used in the sample

SoftWiFi driver to pass data across different layers. This SDR_CONTEXT also contains pointers to

other useful data structures and is used as the sole parameter for many routines in the SoftWiFi

driver.
