Frequencies used for mobile phone technology range from 800MHz to 2.6GHz. These
frequencies have different characteristics and as such have different uses in data
transmission. In fact 4G uses these extreme frequencies, one low and one high. What
are the characteristics of the frequency that dictates the use.
- Given a similar input, and a fair environment to transmit, a signal will
deteriorate depending on the number of oscillations, waves. So as a rough estimate
a 800MHx signal will travel over 3 times the distance of a 2.6GHz signal. [A gross
generalisation but OK]. Hence Higher frequencies are more suitable for city use
and lower frequency for more rural environments.
- The amount of data sent, with the same coding scheme, is dependent on the number
of waves per second. So the higher frequency will be over 3 times faster than the
- Longer wavelengths (lower frequencies) can go through walls better than
shorter wavelengths (higher frequencies) so indoor use is affected if the longer
wavelength is used.
