The race to 4G has already started with an increasing involvement of all cellular industry. With the increasing variety of technologies targeting 4G, and actors in competition, the migration to 4G appears to be a complex thing. This paper presents the expected market requirements for 4G, explains the complexity of future technology landscape, with an emphasis on the standards in competition, and spectrum...
With the advent of the 4G broadband wireless communications, the combination of multiple-input multiple-output (MIMO) wireless technology with orthogonal frequency division multiplexing (OFDM) has been recognized as one of the most promising techniques. In particular, coding over space, time and frequency domains provided by MIMO-OFDM enables a much more reliable detection and decoding of the message...
4G evolution includes improvements beyond 3G as well as nomadic and mobile versions of fixed broadband wireless access (BWA) systems, such as WiFi and WiMAX. The resulting trend is technological and application convergence in an increasingly competitive marketplace. This introductory paper to the Focused Session "Convergence and Competition on the Way to 4G" concentrates on three key contributing...
