Pros
Pros of CDMA
Secure communication channel
Ability to carry out several conversations simultaneously
Can reach even the remotest of areas, so provides wider network service
Operator can give better service, as it increases efficiency
Power consumption is reasonably lesser
Pros of GSM
GSM is very popular, with over 450,000,000 subscribers as of today
This network supports international roaming, hence is the popular choice among users
GSM offers a stable network with a host of robust functionalities
Cons
Cons of CDMA
CDMA, though popular, is more recent than GSM. So it has more flaws than the latter
This method of communication cannot offer international roaming and many other advanced user services
Cons of GSM
Probably the only minus of GSM technology is that it is not accessible in most of the USA, which is ruled by CDMA tech
Where It Stands
In conclusion, GSM undoubtedly wins the network race, as it scores numerically. Still, one would definitely prefer to have a single global standard for wireless telecommunication. This would probably result in some kind of combination of CDMA and GSM networks in the near future.
Maybe the entry of the Apple iPhone 5, supporting both these bands, will mark the start of this universal telecom trend. What do you say?
