Well….Ever since I had heard about CDMA and GSM, I was confused till recently I read an article. I was dying to explain about these two to someone. Coz’ unless I am successful in making someone understand the difference between CDMA and GSM I won’t get it right myself. So thanks to the person who requested this topic.
As it is seen that mobiles have been a basic need of today’s world, one should have all the knowledge about the tiny monster.
Let me keep it simple.I hate being too technical.I shall try to keep my writing as simple as possible so that a lay man does understand the basic difference between these two without putting too much pressure on the small brain.
You heard about CDMA first when big players Tata and Reliance came to the battlefield. However GSM is an old word as compared to CDMA. They are altogether different.
The basic difference between these two is : CDMA (Code Division Multiple Access) phones use WLL (Wireless in Local Loop) technology while GSM (Global System for Mobile) use cellular technology. CDMA is used by Reliance and Tata while GSM is used by other services like orange and Bpl.
So, the difference is the kind of technology they use. We will talk about the two technologies (WLL and Cellular) later.
CDMA and GSM handsets are different too. You might not see any difference in the physical structure but they are different from inside. CDMA handsets are general preprogrammed by the supplier with identity numbers relevant to specific local networks. You can not switch from one operator to another say from Reliance to Tata with the same handset, unless the phone is reprogrammed.
If you are planning to being loyal to Tata then you will have to submit the Reliance handset to Papa ka beta and then take a new handset from Ratan. One more important thing is you can’t get the CDMA phones from the grey market. But this doesn’t hold good for GSM phones. GSM phones are the common mobile phones you are seeing around. They are widely used. You just pick a GSM phone ( you have the option to buy ot from the grey market too), and if you are not satisfied with one operator ( say Orange) you can switch to BPL by throwing your Orange SIM card in the dustbin or giving to an old enemy and buying a new SIM card from BPL. Ofcourse your number will then change. But this is a good way to picha chudao from old girl friends.
Hope this makes you people clear about CDMA and GSM.
Shall discuss about WLL and Cellular technology in the nest review.
And please …don’t forget to post your comments (though more compliments are expected) about my review. This is my only third article. You comment oops …compliments will definitely encourage me to write more.
Enjoy !!!
