Money grabbing bar stewards
"..... Orange is positioning the technology and where it sees the revenue potential"
Ignoring completely the fact that the revenue potential is of increased usage from those inaccsessible areas of buildings in the first place.
This is all for Orange's [financial] benefit not the Customer's, getting paid to have one of its own cells installed so that its network coverage can be "improved". As I see it, the only benefit to the Customer is a practical one in that they can continue use of their mobile in-building. Financially the Customer is paying over the odds by taking up an Orange picocell.
But then again, most buildings I know of have land lines which are fine for calling out from, and can be diverted to from the mobile.
