That is good. Inside, my GS3 grabs 4G at first, transfers some data, thenwill swap to 3G if I'm lower than -110 rsrp. Walking around the 4 corners of the inside of the house and moving to windows makes no changes, but going outside about 10 ft from the house does improve signal enough to stay locked on.(-99 to -104). Ran a couple speed tests outside and got 10.55 Mbps down, about .5 up. Pretty sure they're still tweaking in my area.
