Why do I have such a terrible signal at work. I work in Fort Worth on Trinity Blvd zip 76155, I am only about 7 miles from a Major International Airport, but I can't even use my phone 90% of the time. I have an LG G5 and my signal is either 1x, no service, or a 1bar 3g, inside or outside, it doesn't matter. about 3 years ago, I had a strong 4g signal here, and for the past 3 years or so, the signal just keeps getting worse. My phone is basically useless most of the day.
