said by tiger72:for competition. LTE has the same issue that wifi and existing cellular has - it's a very shared medium, meaning that the trial and theoretical speeds will rarely, if ever be seen in the real world.
It is also much more secure in the "Last Mile" (ie: The connection between the User and the Tower [in this case]) since your connection can be monitored by listening to the radio transmission unlike fiber which where you have to monitor the transfer by "wire tapping" or at the router.
