Data transfer is the latest concern with GSM mobile technology. Higher rate data-transferring is one of the advanced functionalities of 3G and smart phones. Adding to the 3G capabilities of GSM mobile models is the data-transferring feature. The data-transferring speed depends on spectrum bands available from the network service provider. Cell phones of late support two different migration paths - reframing of existing spectrum bands and modified spectrum bands. Various spectrum scenarios are EDGE and UMTS.
3G capabilities of GSM include Internet access, IP connectivity and packed switched services as well. The existing mobile networks offer user authentication, mobility support and circuit switched services. They provide mobile multimedia core services other than packet switched services. Universal mobile telecommunication service is a new radio access network. Based on 5 MHz WCDMA, UMTS offers support for 3G services including data transfer.
GSM is on the go to customer-focused and cutting-edge solutions to face the challenges of 3G services of the new millennium. The focus of mobile technology has been shifted from multimedia services to data transmission at improved speed and with enhanced quality. The movement of mobile technology is directed towards boosting data transmission in terms of coverage and reliability. Users need instant access to information and services, no matter wherever they are. Immediate internet connectivity is a stronghold feature of high-tech mobile phones.
Internet access, web browsing and mobile multimedia capabilities are major boosters for the development of data transmission speed technologies. On most of GSM networks, the current data traffic is less than 5% of the total. EDGE is highly significant for global specification measurement operators of today because it increases the speed of data transmission up to 384 kbps and higher than that in a good radio environment. EDGE is an alternative complement to new WCDMA coverage.
