Licensed spectrum remains 3GPP operators’ top priority to deliver advanced services and user experience Opportunistic use of unlicensed spectrum is becoming an important complement for operators to meet the groWing traffic demand Moving forward 3GPP operators Will have two options to offload traffic to unlicensed spectrum: 1. Wi-Fi (via LTE/Wi-Fi interworking) 2. LTE over unlicensed It Will then be up to each individual operator to choose which approach to use, which Will depend on a number of factors

FolloWing chapter introduces the mobile communication, gives a short history of Wireless communication evolution, and highlights some application scenarios predestined for the use of mobile devices. Cellular and Wireless based systems related to different generations of mobile communication, including GSM, IS-95, PHS, AMPS, D-AMPS, cdma2000 and WCDMA are also described by this Chapter. Much attention in this chapter is given to express the Wireless based networks, such as Wi-Fi and WiBro/WiMax, and Wireless broadcasting systems, including DMB, DVB-H, and ISDB-T. We conclude the chapter With the future vision of mobile communication evolution

Digital mobile Wireless communication and the Internet have undergone a fantastic growth in the last few years and, despite originating from two different worlds, they are converging. This convergence corresponds to the evolution of mobile systems towards the highest broadband data transmissions (GSM, EDGE/GPRS, UMTS then HSDPA), while the computing world gets equipped With Wireless technologies such as Wi-Fi or Wi-Max.

Today Wireless is becoming the leader in communication choices among users. It is not anymore a backup solution for nomadic travellers but really a newmoodnaturallyusedeverywhereevenwhentheWiredcommunicationsare possible. Many technologies evolve then continuously, changing the telecom- munication world. We talk about Wireless local area networks (WLANs), Wire- less personal area networks (WPANs), Wireless metropolitan area networks (WMANs), Wireless Wide area networks (WWANs), mobile ad hoc networks (MANETs), Wireless sensor networks (WSNs) and mesh networks. Since we can find today a multitude of Wireless technologies we decided to group a numberofcomplementarytechnologiesintoonedocumenttomakeiteasierfor areadertounderstandsomeofthetechnicaldetailsofeachmedia.

Although the origins of radio frequency based Wireless networking can be traced back to the University of Hawaii’s ALOHANET research project in the 1970s, the key events that led to Wireless networking becoming one of the fastest groWing technologies of the early 21st century have been the ratification of the IEEE 802.11 standard in 1997, and the subsequent development of interoperability certification by the Wi-Fi Alliance (formerly WECA).
