Frequency ranges for mobile phone providers within the UK are listed below.  You maybe asking yourself why these are important and how they may affect your business.

Imagine a grid fence with a gap 9.6cm, the below frequencies will all fit through until you hit anything greater than 9.6 now that the higher frequencies do not fit through there will be no signal.

If you have a reinforced or reflective building the frequency of your chosen supplier may not penetrate the building and therefore be useless when inside.
