I live in Central Texas and I have seen a cell site built about .44 miles away from my house. I use sprint's EVDO Rev. A data card. Recently I have been experiencing a drop in service the dBm fluxing ALOT, dropping from 78 dBm all the way to 102 dBm... Ive worked with Sprint's Advanced technical support and they are supposed to be sending a tech out to the nearest cell site to check the orientation of the antennae... She said it seems like my card isnt locking on a specific site, but bouncing between sites. Has anyone else around here experienced these problems if so, any helpful tips of pointers? I am looking for some cell site maps for sprint in my area, does anyone know of any... I am also expecially interested in the actual equipment and how it works /specs as well. I do understand different carriers use different technologies and such. And I am sure there are some confidentiality issues there, but any and all help would be greatly appreciated.
