TU (Time Unit)

TU (Time Unit)

In the IEEE 802.11 standard, a unit of time equal to 1024 microseconds, is used in the definition of a number of intervals. The use of the term is to avoid imprecise confusion with the term "millisecond" while maintaining intervals that are easy to implement in hardware that has a 1 MHz clock (by dividing the clock signal in half ten times, rather than operating a phase-locked loop or digital divider to divide such a clock signal by 1000.
