This means a substantial spectral efficiency incr ease\, which must be achieved while maintaining or even improving the powe r efficiency. To accomplish this one needs to employ new transmission tech niques\, with the most promising ones based on the use of a large number o f antennas. For this reason\, massive MIMO (Multiple-Input and Multiple-Ou tput) schemes\, involving tens or even hundreds of antennas\, are a key co mponent of 5G\, since they allow high capacity gains\, while enabling sign ificant power savings. Clearly\, the evolution beyond 5G will involve even more antennas.\n\nA new and revolutionary technique able to improve subst antially the performance of wireless communication networks is to smartly changing the propagation characteristics of the wireless channel through t he use of RIS (Reconfigurable Intelligent Surfaces)\, which are made of a large number of low cost passive reflecting elements able to independently change the amplitude and/or phase of the incident signal so as to achieve specific propagation effects. LIS (Large Intelligent Surfaces) are the na tural evolution of massive MIMO schemes. They will employ many thousands o f antenna elements\, allowing huge capacity gains\, as well accurate posit ioning and efficient energy harvesting techniques. However\, the implement ation of these techniques involves considerable challenges.\n\nIn this tal k we give an overview of potentialities and challenges of systems with a h uge number of antennas. We start by making an overview on the evolution fr om MIMO to massive MIMO\, and its extension to RIS and LIS and cell free s ystems. Then we present the main features of those systems\, as well as th e implementation constraints and challenges\, as well as potential solutio ns.\n\n[]\n\nSpeaker: Rui Dinis received the Ph.D. degree from IST\, Techn ical University of Lisbon\, Portugal\, in 2001 and the Habilitation in Tel ecommunications from FCT\, Nova University of Lisbon (UNL) in 2010 where h e is a Full Professor.
