Wave degradation over distances

[Securityman]

This is probably a simple question, but here is a little background from which to view the problem. A cellphone tower transmits a 4G data signal at 700Mhz to my smartphone. Assuming that it does reach my phone does the wavelength of that databurst change in transit? Thanks.

The only change in wavelength would be as a result of Doppler shift. Unless you are moving very fast, the effect would be neglible.
