I already lock the UE's to the Frequency. I never thought of locking the
PLMN. What version is it and where did you get it ?
I really doubt that there is another 3.65 Telrad user out here but I
suppose it's not impossible.

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.
YMMV

some folks may have bought into that I guess... blindly without doing
the math ? Maybe, I suppose.

in the ass. Here's one of them. This is 8.3Km. Perfect LOS; clear on
F3 from end to end. It is the only UE on this sector. Dead center of
the beam, and it disconnects randomly. Why?

they pretty much encompass me and their reputation for being
stupidly,
ridiculously, atrociously over subbed, and installing ANYONE

so
you're not going to serve 186 UE's at 10 to 25Mbps each like the
Power
Point slides show... the math isn't
there.
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.
