预计未来五年无线通信的需求将增长40倍以上。满足这一需求的一项潜在技术是大规模MIMO（也称为大规模天线系统、大规模MIMO、ARGOS、全维MIMO或Hyper-MIMO），这是一种多用户多天线无线技术，它承诺比4G技术在频谱效率上有数量级的提高，并伴随辐射能效的提高。大规模MIMO的显著特征是大量的服务天线——可能是数百甚至数千个——为数量少得多的主动自主终端工作。以这种方式打破服务天线和终端之间的传统平价是一种改变游戏规则的方式：最简单的多路复用预编码和解码算法可以接近最优，昂贵的超线性40瓦功率放大器被许多低功率单元所取代，大数定律的有利作用可以极大地促进功率控制和资源分配。
Demand for wireless communications is projected to grow by more than a factor of forty or more over the next five years. A potential technology for meeting this demand is Massive MIMO (also called Large-Scale Antenna Systems, Large-Scale MIMO, ARGOS, Full-Dimension MIMO, or Hyper-MIMO), a form of multiuser multipleantenna wireless which promises orders-of-magnitude improvements in spectral-efficiency over 4G technology, and accompanying improvements in radiated energy-efficiency. The distinguishing feature of Massive MIMO is that a large number of service-antennas - possibly hundreds or even thousands - work for a significantly smaller number of active autonomous terminals. Upsetting the traditional parity between service antennas and terminals in this manner is a game-changer: The simplest multiplexing precoding and decoding algorithms can be nearly optimal, expensive ultra-linear forty-Watt power amplifiers are replaced by many low-power units, and the favorable action of the law of large numbers can greatly facilitate power-control and resource-allocation.
