Is moving fast will effect WiFi transceiving beavior?
At a speed of 119 m/s and a frequency of 2.45 GHz, the doppler shift will be 971 Hz. See this on-line calculator.

That is what a receiver may have to cope with. If you then consider the accuracy of the crystal oscillators at either end of a radio link, the frequency differences are likely to be in the realms of hundreds of hertz BUT the receiver copes.

The receiver copes by tracking the signal it is trying to receive with several methods but ultimately it boils down to a phase locked loop (PLL) adjusting a voltage controlled oscillator (VCO) to keep absolutely spot-on in sync while decoding data.

I'm going have a stab at a guesstimate that several kHz of clock difference can be tolerated using this method. If there is a mechanism that can take account of clock differences then it will take account of doppler shifts too. The only thing to really shake this theory is really extreme accelerations because the "system" will have a small time lag and it might just get out of sync for a few moments and of course reception of a packet may be jeopardized and that packet may require to be retransmitted.

I recently watched a programme on TV about the sad loss of Malaysian Airlines flight MH370 - the system that was used to receive the hourly automated transmissions also "held" values of control voltages used to tweak shifts in transmit and receive frequencies and these numbers held all the information about doppler shifts too. In effect they were able to tell what direction the plane was flying and pin-point a crash area of about 100 sq miles. I was amazed that the "tweak" parameters were held in a data base and that this information was available retrospectively.

The slow moving (or static) "value" offset would represent the almost fixed difference in frequency between the tx and rx oscillators whilst the more dynamic changes would be the doppler shift effect. See this article about the doppler method used.

Ultimately, what I'm labouring to say is that doppler effect is likely to be "fixed" by the same mechanism that fixes the difference between clock frequencies at either end of the link.
