I've had weak signal at home for years, but it wasn't until I got my latest phone (Android) that I could actually see the signal strength. It was -100 to -120 dBm. That is supposedly not even enough signal to make a call (the bars in your phone display don't mean much). But, I get about the same thing at the office in Richardson so I figured it was OK. I talked to customer service about it and they sent me a femtocell. I now get signal in the -50's. There was no cost to me. If you are already with a carrier you think is decent otherwise and your main issue is signal at home you might try mentioning the femtocell. I understand they are becoming more popular. It basically creates a "mini cell" right on your house. My phone DOES NOT support WiFi calling so this is not a wireless router. WiFi calling may be the solution for some. It is also not a signal booster. Some may be OK with one of those.
