Difference Between CDMA and GSM Mobile Networks

Are you an iPhone user or someone who discovers the difference between CDMA and GSM mobile networks?

Currently, the largest US mobile phone service providers are divided between CDMA and GSM network technologies. For example, Verizon CDMA and AT&T GSM.

This distinction is important to me because I am an iPhone user who is trying to discover which network type best suits his mobile needs. So try to answer this question, what is the difference between CDMA and GSM?

CDMA Code Code Multiple Access

GSM Global Mobile Communication System

Here is a distribution of areas where the two services can be distinguished:

Coverage- Check local coverage maps to discover which network is optimal to it's place. You will usually choose between one or the other.

Speed-CDMA has traditionally been faster than GSM, but the history of the two networks has progressed. CDMA uses EVDO and GSM uses EDGE to drive speeds. EVDO delivers high speeds, but EDGE is more sensitive to interference.

Subscriber Identity Module (SIM) Cards – GSM uses SIM cards that are connected to the network instead of the phone. Therefore, you can easily transfer your SIM card with contacts and information to different phones. CDMA does not have a SIM card and all the information is transferred from phone to phone and makes the old phone unusable.

International roaming GSM is an international network offering more comprehensive services in countries outside the US. CDMA is still available in some countries.

help? Overall, there are different strengths and weaknesses of CDMA and GSM.

For all iPhone users who are switching to Verizon iPhone or not, I hope this explanation somewhat helped the difference between CDMA and GSM. I know my AT & T network was more impressed after I did this research …
