Sorry—5mb cannot compete with gigabit.
AT&T the owner of a majority of the land lines and switching equipment is in a transition from landlines to tower based communications. So much so minimal maintenance is being done on the current landlines. AT&T has gone from a person seeing a half a dozen AT&T service vans a day in any mid size city to a rarity. The only question really is will they complete the transition before the now aging cables and trunking systems to outlying areas begin to fail due to age?
The lines in my area were replaced in the late 1970's as well as the SLICK System installed and then only because my dad a long time Ma Bell employee went to the state Public Service Commission because the lines in our neighborhood failed every time it rained.
I just got LTE and I was wrong its 15mb
