PPN is something about the tower's ID number I think
FER frame error rate

Thanks for the excellent info.
The TX and RX strength is in dBm... I have verified this in my lab with my Nokia 6385 CDMA. I guess that most of you guys would know how dBm work, but for anyone that doesnt know, its all referenced to 1mW (one milliwatt)..
TX power...
10dBm=10 milliwatts
20dBm=100 milliwatts
30dbm=1 watt
RX level.
-100dBm is about 2 microvolts (basically full limiting on a normal 2way radio receiver)..
It seems that the CDMA will work ok down to -100dBm, and you might be lucky for it to work at -105dBm. The RX signal when you are close to the transmitter site (say, 200 metres away) would be around -25 to -30dBm.. (at least thats what I have found).
PPN is basically an "identification" number for the current site that you are on.
I will work my way through the other pages of info and post any further info that I find.
Cheers,
