And how do you do that with multiple set top boxes that don't have wireless connectivity, or while you are out and everyone else in your home is, well, still at home. Pony up for a wireless ethernet bridge for even more money? Buy a second phone so everyone else in the house doesn't lose their connectivity when you leave the room? A mobile phone hot spot is hardly a convenient substitute for a fixed wired modem unless you are a recluse nor would it provide the same performance as an external antenna setup would.
