    Velocity, wavelength, and frequency of a wave relate by the following rule:

    v = \lambda f, where \lambda is the wavelength.

    If the wave is a signal, as in radio or television or whatever signal, it is a eletromagnetic wave. Does this ring a bell for you as to the velocity of the wave?

    \lambda=\frac{c}{v} where c=speed of light in a vacuum ( 3 \times 10^8 \ \ m/s \ \ or \ \ 3 \times 10^{10} \ \ cm/s) and v = frequency in hertz (hz).

    1800 \ \ Mhz \ \ =1.8 \times 10^9 \ \ hz

    A mobile phone signal is a eletromagnetic wave, and as 'masters' correctly pointed out, and all eletromagnetic waves have the speed of light, c, in the vacuum. This speed is very similar to that in the air, so you just ignore the difference.
