To be Really Honest, Evenb I don't know the Technical Mambo- Jambo of these Technologies, but I do know the fair diffrence between them. For a novince or a person, who is new to mobiles n cell phones, this would be a intro to CDMA and GSM.
Lets Start....
So what are these CDMA and GSM ? Well These two are the Latest and Hottest technologies in India, which are current backbone of our Mobile phones. Even though both services have similar goals, yet they both are have few specific Features depending on the type of user.
GSM :
1) This is the Service which our older providers Like Airtel,Essar, Escortel etc are providing.
2) This service is Provides features like -
(a) Call Forwarding:
It lets you forward your calls to another Mobile or a
Landline Number.
(b) Voice Mail:
This is Similar to your Answering Machines.
(c) Call Waiting:
When you are talking to some one, then this feature can
add one more line to your Mobile. Meaning thereby you
can receive a special beep(s) indicating that someone is
calling you.
3) It enables you to use your mobile while your are away from your Town/City. This is Called Roaming. You can Choose between National or Internationl Roaming.
4) They come in two options. Pre-Paid and Post Paid.
(a) Pre - Paid:
You are supposed to buy a Coupon ( worth few hundred buck )
Every month. The amount adds to your previous
Balance.
(b) Post Paid:
You get a Monthly / Bimonthly Bill, just like your normal Landline
phone.
5) GSM enable Phones requires a tiny Chip called (SIM Card). This Card stored your phone book, SMS and your own number.
6) You can change your handset anytime you want. All you have to do is place the SIM Card in the New phone.
7) The call Charges range from Rs 2-3 per min for outgoing calls. (ALL INCOMING CALLS ARE FREE IN INDIA)
CDMA
1) These are the one BSNL and Relience are offering.
2) They are providing - FREE SMS ..... Rs 40 - Rs 1 Per min outgoing call (CDMA to CDMA)
3) Though this service is not as expencive as GSM yet the first time investment is too much. (Around Rs 20,000-/ )
4) You require a special handset, which is programed by your mobile service provoider.
5) You do NOT have any roaming in CDMA. This means You can only use your cell phone within few kilometers.
6) It is also called as WLL ( Wireless Local Loop ).
So after all said and done....if your job requires to call quite often and you do not go out of town to much, then Your pick should be CDMA. Otherwise if you are on the move all the time ,then GSM is for you.
Which ever phone you pick, just remember the MOBILE MANNERS and HAPPY TALKING !
