A millimeter-wave massive MIMO system for next generation mobile broadband

The spectacular growth of mobile data traffic calls for drastic improvement in mobile network capacity beyond current 3G/4G networks. In this paper, we describe a millimeter-wave mobile broadband (MMB) system that taps the vast spectrum in 3 - 300 GHz to meet that demand. We discuss the unique advantages of millimeter waves such as spectrum availability and massive antenna arrays in small form factors. We also describe a practical MMB system design that provides Gbps data rate at distance up to 500 meters and supports mobility up to 350 kmph. We show in system simulation that an MMB system with basic configuration achieves more than 30 times cell throughput and cell-edge performance than a 20-MHz LTE system.
