I don't think this question deserves the time to answer.

Please use plain English, not txt speak like wot/what and no/know.
Thankyou.

Do you think there is no encryption on CDMA?

You cant pull a CDMA signal out of the air and crack it realtime, but its possible with GSM with appropriate resources.

On either network type, you could initiate a data session, and use encrypted VoIP services.

Gone are the days of hearing a cellphone call of somebody driving past, coming through on your Microwave oven or whatever....

Both are pretty secure. If law enforcement wants to listen, they will either go through the telco directly, or the government can access many forms of comms through the likes of the Waihopai station.

Without wasting a lot of time explaining, CDMA is far more secure. In fact it started off as a way for the US Navy to communicate and transmit sensitive information.

Is it just me or does there seem to be a lot more people on here lately that should stop taking whatever it is they are taking and be started on a very rigid course of normal pills?

Nope. I'd just say that people come here to learn.

Obviously there's a misconception that GSM is better than CDMA, simply because, well, because... Whatever.

There are differences in the technologies, and people don't understand all these differences because of ignorance. Knowing one side only is bad - like Linux zealots making fun of Windows fanboys, simply because they don't know better (or they read too much Slashdot) and vice-versa.

(Running now because I am sure Linux Zealots will raise their voices here).

Did someone say Linux zealot?

The origins of CDMA date back to the end of World War II and the 1950s when spread spectrum technology was first invented. Initially its use was confined to small aperture satellite services and to military applications, where it was used to avoid jamming and detection of sensitive transmissions. (from http://www.moonraker.com.au/techni/cdma.htm).

I think that people generally dont know how to Google things particularly well (through no fault of their own - you dont know what you dont know), and that Googling should be a Form2 compulsory subject.

P.S. I run Linux and Windows, each does important things for me that the other struggles with, and I dont read more than about 2 pages a month on /.

Alright dust off the history cap.

Actually spread spectrum was invented by Hedy Lamar during WWII as a way control torpedos which at that time ran a single frequency so they were easy to jam. Hedy was actually more famous as the first actress to appear naked in a cinema movie.

The Americans didn't take up her invention (patent) during WWII but they did pick it up in the 50's when the patent expried. She never earned a bean from it. Apparently she got the idea for Spread Spectrum frequency from watching her then boyfriend play piano - something about the change in key.
