AGREDO-MENDEZ, Guefry Leider; JOJOA-GOMEZ, Pablo Emilio  and  ALMENAR-TERRE, Vicenç. MIMO systems with a large number of antennas: a key factor for a 5G wireless network. Entramado [online]. 2015, vol.11, n.2, pp.250-261. ISSN 1900-3803.

The demand for high speeds and capabilities in wireless data communication, together with an increasing traffic of services such as high definition video, video phone calls, and synchronization of photos and videos from mobile phones, pose a challenge that is expected to be overcome with the work being done to establish a 5G wireless network. Since one of the alternatives involves using a large number of antennas, there is a need to learn about and be prepared for this new paradigm as soon as possible. This article provides a review of various technologies that have currently become the center of attention and conform with the denomination of large scale MIMO systems, including among others: massive MIMO and full dimensional MIMO systems.

Keywords : 5G; Large-Scale MIMO system; Massive MIMO system; FD-MIMO system; Wireless Communications.
