Well, I'm not sure if there is a database of who is actually colo'ed on a tower. But as for who a tower is owned by, The FCC database works. They also have a cool google earth file that will show you the location of all of them http://www.fccinfo.com/fccinfo_google_earth.php Nick Olsen Network Operations (855) FLSPEED x106 ---------------------------------------- From: "harbor235" <harbor235@gmail.com> Sent: Tuesday, October 26, 2010 11:47 AM To: "NANOG list" <nanog@nanog.org> Subject: Cell sites I am hoping someone can guide me to a internet resource that provides information on newly contstructed cell sites and what provider they are affiliated with?
