I just joined the RF Cafe Forum and I saw your old mail. In addition to what you might have pls check Aircom' website: www.aircom.co.uk
. Click on Training, then Technology page for non vendor specific training. You can later check the Enterprise page for Aircom' RF solutions.
For TEMS INVESTIGATION you go to Ericsson's website. They have training schools all over the world where u can learn their solution. But you can't just learn TEMS, you have to do a few pre-requisite
Good luck in ur endeavour. U can share what good info you might already have with me too. Cheers
