WiMAX is an upcoming technology of the modern times. WiMAX Forum was founded in 2001 with the key target of enhancing broadband wireless access levels. A decade later, this technology is accessible and provides a reasonable solution for speedy IP based 4G mobile broadband, entirely supporting bandwidth-concentrated services, such as quick internet service and television, as well as fewer bandwidth-challenging, but more latency-responsive facilities, such as voice-over-IP calls. A number of features of the WiMAX application, with special focus on multi-user multiple-input-multiple-output variety methods, synchronized verification in a diverse network surrounding, etc. has been discussed in this text. This book is a compilation of data dealing with significant aspects, characteristics and functions of WiMAX as an innovative technology.
