I work in a Call Center Facility and some incoming calls come thru by a Telular Fixed Cel Terminal. The problem is the signal strenght in the CC wich is very poor, and there is no option for moving the Terminal to a better place. What is my best option for gaining better signal strength for my Tetular CDMA CPE?

You're beyond my ability to help but I can tell you this much, if it were me, I'd start by contacting the manufacturer of the existing equipment I have. They would know what can and can't be done to/with it and also, what other equipment you could maybe add to increase your signal strength. That doesn't necessarily mean you have to deal with them. You can always look elsewhere once you know where you stand and what, if anything, can be done to improve your situation.
