I have a crappy cell signal in my home office that typically shows 2 bars on my new iP5. If I enable LTE, the cell signal drops to 1 bar and even to 'no service'. If I turn LTE off, the cell signal comes back. Also, with wi-fi off, I do not get LTE in my office but can pick it up from outside which confirms that it's a weak signal in my area. The LTE effect on the cell signal occurs regardless of whether wi-fi is on or off. This is repeatable. So wtf?
