Except that mobile phones are wireless and are subject to inverse square law as far as signal is concerned.
Signal theory traditionally operates with log scale because it simplifies math greatly and makes graphs manageable. If you say have noise floor at -30dB, expressing it on a linear graph is not very convenient.
