I'm genuinely curious here. Isn't dBm just the numerical version of the signal strength which is represented by the bar graph? Sure the dBm number would give you a more accurate reading but it seems not worth the hassle for something the bar provides a quick representation to? If you have a more in-depth answer I'd love to hear it. I'm just going off of what a quick google search fed me.
As far the towers - do they have any sort of load balancing between them? And do they all have a separate number of T1s? I suppose it would make more sense to load up the bandwidth on one tower in a heavy population area instead of adding multiple towers. If you have any deeper knowledge into this I'd love to hear it
Yeah the bars is much quicker to view on most phones for sure,and is pretty accurate. I guess I was just throwing something out there that should be looked at if you're really getting technical in trying to figure out what network is faster.I have a Storm with an app that makes it easily viewable,and my Sprint data card shows the dBm reading right below the bars when I open up the connection manager.
Caindris, Yes, they do have load balancing,and the more populated areas have more T1 lines,but like in the area I live in the Sprint tower has 1 T1 line,and the Verizon has 2.I know this because of the speeds I get is double on the Verizon tower even though my dBm is lower on the Sprint tower.The odd part is I live in a rural community and I have ZERO idea why Verizon put 2 lines on it,although it could be because it's fairly close to an interstate.
Don't get me wrong I'm no expert at this.What little I've learned was by trial & error,and research. When I moved to this area I could get nothing but dial-up,so I got a data card,well my dBm was way high so I had to get an amp and then a directional antenna/wiring and mount it on my house and point it towards the tower(s). I probably know more than your average person,but I'm not a guru that's worked on towers or anything.....wish I was though.
I learned a lot at a forum called evdoforums.com.When you run your home internet off a data card,you get really anal over your dBm.Man,everything is flying right now,but when the leaves get back on the tree's,and the humidity kicks back up (I'm in the South) things will slow down fast.....not such a big deal for me on a phone though.
