Wireless communication system

- Even though the age of wireless communications is upon us, many of us still deal with a plethora of cables that snake along and behind our desktop computers. Cables connect our printers, scanners, keyboards, digital cameras and any other peripherals that enhance our computing experience.
The main evolutionary steps from the current heterogeneous wireless networks towards the future integrated-services multimedia network are outlined, introducing the development of mobile networks from second to third generation, the vision beyond third generation, and the major technical challenges.
An updated vision on multiple access protocols has been provided, focusing on the wireless domain and multimedia traffic. All those protocols adopted in current wireless communication systems are an adapted version of traditional and well-known mechanisms designed for wired networks or for specific wireless scenarios and applications.
