Wireless networks are implemented as projects by investors to make returns on investment. They are used by subscribers using wireless devices that draw services. In so doing they generate traffic that is served by the network in return for revenues through tariffs. The networks and the devices exploit state of the art technology and that technology is developing through a process of research and development at firm, national, regional and international levels. That return on investment has traditionally been very high through voice and simple data services. This Research and Development is yielding diverse data services but revenues are reducing leading to industry turmoil. Choices are now manifold and investors need guidance.
Wireless systems are used in both access and core networks. Both because of the last mile bottleneck and because of the vast numbers of connected terminals (and the high investment required for coverage and capacity) wireless access networks command the most attention. Of course wireless networks both complement and compete with fixed networks. Wireless access networks offer mobility or nomadic use which makes them generally more attractive than fixed networks, but this is offset by greater cost, particularly for high-speed high-volume use. However there’s evidence that the cost gap between wireless and fixed is narrowing.
Rosillo.Net has consulted on every type of wireless network including:
Existing cellular networks including 2G (GSM N-CDMA, etc.) and 3G networks
Emerging technologies such as LTE
Technologies for specialist use such as TETRA and GSM-R
WiMAX, WiFi and other broadband wireless access technologies.
Today the business and technical distinctions between wireless networks are fading. Due to developments such as multi-standard terminals and the use of Internet Protocol (IP) to deliver many different types of content, customers of wireless networks can use many different network technologies seamlessly.
