[SOCALWUG] Difference between Frequency and Phase?

[Blair Templeton]

Hello,

Im having difficulties understanding exactly what Phase means, Im reading 
802.11 Wi-Fi handbook
(Neil Reid&Ron Seide) which explains that frequency is the complete cycle of 
a wave.
Phase is where the wave begins its cycle. Makes sense I guess.
What becomes confusing is BFSK and BPSK, BFSK sends an on or off bit with 
each frequency,
BPSK sends two states, a "one" with one phase and "zero" with another phase.
If phase just determines at what point in time a frequency begins its cycle, 
how can there be a modulation scheme based on phase?

Thanks
