The huge take up of mobile broadband has taken everyone by surprise. At first it was treated as something that would disappear after a while, but the figures of mobile broadband subscribers speak for themselves.
In fact, on some networks, data traffic exceeds that of voice traffic.
This is beginning to throw up some questions as to whether or not the mobile broadband network can actually stand the test of time or will it eventually run out of capacity.
Some networks who have been investing in their equipment to make sure that this sort of problem does not occur.
But if the mobile phone network is anything to go on, then an example of capacity limitations can be found when the network is busy and calls cannot be made.
Is this what is in store for all of the people who have signed up for mobile broadband?
