However, in real-time applications, due to technical limitations and quality purposes, the real number is usually lesser than this number.

Using CDMA has its own advantages and disadvantages. The main advantages of using CDMA include low interference due to transmission bursts, usage of rake receivers to improve receivers. Usage of flexible transfer, which helps the switching of mobile stations without changing the operator.

The main disadvantages of CDMA include delay due to the large size of code, requirement of a precise, time synchronization, also gradual transfer often saturates radio capacity. This is due to a very specific reason. This resulted in better connectivity, better capacity, and better speed. These help it to attain better connectivities and higher speeds. This makes the system more efficient and does not make any issues while transferring data. This is one of the popular air interfaces used in mobile devices.

This is an upgrading of CDMA where very less speed is used as per the standard. This can be utilized for the data in the system. UMTS phones specifically are not available as it depends on any of the access networks to provide support. The signals are not handled easily and, in some cases, can be in different paths. This makes communication difficult though it is done.

This is the reason that UMTS depends on other networks. The signal can be handled easily in any paths, and this explains the efficiency of the system. WCDMA uses radio technology to transfer data.
