Guide to GSM - What's the fuss about ?
What will the future bring?
GSM development has not stopped yet. Work on the standard is now in the third major phase, generally referred to as Phase 2 Plus. A key element of the work concerns data transmission, including bearer services and packet switched data at 115kbit/s.
What is more, GSM standards developers have recognized that an increase in the capabilities of mobile systems brings a demand from users for ubiquitous coverage and for increased mobility within their fixed network infrastructures. So GSM is to form the basis of the most comprehensive mobile phone systems yet - satellite-based systems that will cover the entire planet.
GSM is continuing to enter new application areas, such as the indoor business environment where the deployment of micro and pico base stations will provide seamless wireless access to advanced business communications services. GSM can also provide an alternative to fixed line public telephony through wireless local loop (WLL) services.
The core standard is now well tried and tested, but is also constantly developing. Since GSM first entered commercial service in 1992, it has been adapted to work at 1800MHz, and at 1900MHz for the American PCS operators.
GSM is the only international standard mobile phone system, which is being seriously developed at this level. Developers of other mobile standards may share the same vision, but none can claim the same level of global availability and high-speed data specification that GSM has today.
GSM systems were designed from the beginning with a digital future in mind. Operators will only need to carry out an upgrade in order to bring exciting new services on stream. There will be no need to install new infrastructure, or need to go through a large network re-planning project. With the help of leading suppliers such as
In the new information age, the mobile phone will deliver much more than just voice calls. It will become a multi-media communications device, capable of sending and receiving graphic images and video. The mobile terminal of the future will connect to corporate LANs, enabling business people to share information using workgroup-computing applications. It will also allow them to talk to traveling colleagues via a wireless videoconference link.
