We experienced these random disconnects as well. Went to the customer site, hooked into the UE and waited (a few hours) and lo and behold, there was another Telrad operator transmitting into our area with a very weak signal.
You could watch the UE attempting to connect to the other operators equipment. Don't know why and Telrad never had a believable explanation. Telrad UE will randomly attempt to migrate to any available BTS unless you are using manual PLMN selection or manual frequency selection. We have mitigated this by using manual PLMN selection or manual frequency selection at the UE. There is a special version of the firmware that allows this. Worse yet, the competition BTS was at -122 to -125db and our signal was at -95. Drove us nuts. I filed several reports of this with Telrad and eventually got a firmware that allowed us to lock the UE to our network. End of those problems. Latest 6.6 release is the most stable of all.

I remember those slides.....I kept my mouth shut while they did their presentation, but I commented to my colleagues afterwards about the fact that their graph showed the BS at 100% airtime utilization for 16 hours a day. I don't remember what they were trying to demonstrate with those charts though. _______________________________________________ Telrad mailing list [email protected] http://lists.wispa.org/mailman/listinfo/telrad > Joe Portman Alamo Broadband Inc. www.alamobroadband.com
