Well buddy if you were home all day and you had a Time without Signal of about 50%, I hate to break it to you but your house is a dead zone. I had this issue for the last 3 years with my home being a dead zone for all cellular activity. On my old LG Voyager that showed both 3G and 1x bars, I'd have 3-4 constant bars for 3G and only 1 or no bars for 1x. This was consistent even after getting my Droid X, its just less up front about showing you your true radio signal.
A good signal strength is -50 to -85 dbm. This will allow you to make calls without voice chop or dropping. Any higher than -85 and you start to see some quality issues. -100 and up expect to miss calls completely as you have no signal. Note this also affects texting SMS. If your dbm is very low (ie - -85+) expect your texts to either take awhile to push/receive or even worse expect to NEVER send/receive them.
The solution for me was to buy a Verizon Network Extender. I hooked it up, ran the GPS antenna cable to my nearest window, and in 10 minutes I was up and running. Basically now I get constant 4 bars on my old phones, and my signal strength dbm is now -60 and lower. My Cell Standby never reads anything more than 0%, and this is because when you leave the vicinity of your network extender, it has to switch networks to the nearest cell tower. So theres an intermittent pause between towers where you have no signal for approx <5 seconds. No big deal and won't affect battery any.
I hope this helps. (please click thanks
