WiMAX: a competing or complementary technology to 3G?

This presentation will contrast WiMAX and 3G wireless technologies and will discuss whether the two technologies are competing or complementary particularly for developing countries.The eventual convergence of the two in what is called "LTE or Long Term Evolution,or Super 3G, S3G " will also be discussed. To this end , the challenges that lie ahead in developing complex MIMO radios with multi-band front end modules (FEMs) will be discussed.Examples of WiMAX and LTE radio architectures will be presented.
