Just calculate it.
Wavelength = c / f
where c = speed of light ~= 3*10^8 m/s, f = frequency
The default channel, 26, is somewhere in the high region of the 2.4 GHz ISM
band, which would be around 2.485 GHz => 2.485*10^9 Hz.
Wavelength(high end) = (3*10^8 m/s) / (2.485*10^9 1/s) = 0.1208 meters =>
12.08 cm.
The low end of the 2.4 GHz is 2.400 GHz. so the wavelength there is:
Wavelength(low end) = (3*10^8 m/s) / (2.0*10^9 Hz) => 15 centimeters
So the wavelength is between 12 to 15 centimeters, depending on which
channel you're sitting on. 13 centimeters is a good answer.

I am using cc2420 chipcon with micaz mote
I think I should review CC2420 datasheet
Thanks for all

It depends upon at which frequency they are working, I guess.

Hi all,
Which is the wavelength of the signals generated by the motes in the TinyOS
implementation?
Thanks a lot.
