What are the advantages of CDMA over GSM?
Advantages of CDMA One of the main advantages of CDMA is that the connection only drops when the phone is at least twice as far from the base station. Therefore, it is used in rural areas where GSM cannot work. Another advantage is the bandwidth, it has a very high spectral capacity, allowing it to serve more users per MHz of bandwidth.
