We can't change any construction structure unfortunately as it's a rental. Outside it's roughly the same but if you stand in the right spot will get 4 bars. We have good internet connection so that won't be an issue. For call quality it's fine, it's a bit slower when having to use data only here. My biggest complaint is how it is affecting my battery life, under stats it's 50% plus most days (cell standby+phone idle). I'll neighbors how is their signal strength and what service they have to get an idea if it's better, worse, or the same. Other phone in the house is an iPhone and they have noticed the lower signal strength as well.
