Sometime back myself and friend were discussing about the wireless, when we were travelling back home and seeing the cops speaking on wireless phones. It was totally inaudible with so much noise. My friend was saying that wireless phone is very cheap but very insecure. CDMA phones are very costly but very secure too. GSMs scale up in between them.
I am quite interested in finding out where can be find more information in analysis of the same -- cost wise, infrastructual investment, security etc. I was searching out for fundamental info but could'nt locate one.
