Project Helping Shape Future of 4G Communications
Key elements of the next-generation of mobile technology are under development at UT Dallas, promising better Internet access, lightning-fast downloads and seamless global roaming.

A two-year project focuses on the advanced algorithms required to orchestrate the complexities of fourth-generation, or 4G, communications. Those complexities arise in part from what’s known as MU-MIMO – multi-user, multi-input, multi-output technology – and particularly from the proliferation of antennas.
