Future Mobile Data Communications Services

• As mentioned in the previous section, the air interface is the bottleneck when transmitting data between a mobile station and a data network using the current mobile services. A major part of the evolution of mobile data communications services is dependent on the evolution of the GSM.
• GSM radio access technology has a clear evolution path and, eventually, it will provide a bandwidth wide enough for various kinds of services. Hence, GSM radio technology will remain an essential access network well into the next century.
