# Benefit of higher frequency transceivers?

What would be the benefit of higher frequency transmission? I was browsing through a website looking at some parts and came across two transceivers, one operated in the 434MHz band and the other the 915MHz band. From my perspective, it seems that it would consume more power transmitting at over twice the frequency.

If sending data, a higher transmission frequency means a higher data rate. Consider an FM transmission - it "deviates" a carrier between two different frequencies in the spectrum ($f_0$ for data 0 and $f_1$ for data 1) and, for a given frequency deviation (measured in hertz), the receiver is able make a more robust distinction between the two frequencies when there are more cycles of the carrier wave to detect.
