Abstract: The Internet of the future will to a large extent rely on mobile networks. Mobile data grew with 70% in 2012 and is predicted to grow 13-fold in the next 5 years. This puts very high demands on the development of mobile access technology. MAMMOET will advance the development of Massive MIMO (MaMi), a new and most promising direction in mobile access. MaMi makes a clean break with current technology by using several hundreds of base station antennas that operate phase-coherently together, simultaneously serving many tens of low-complexity single-antenna terminals in the same time-frequency resource. MAMMOET will demonstrate that MaMi can increase both data rates and the overall spectral efficiency by up to ten times, while decreasing the transmitted radiofrequency (RF) power by many orders of magnitude. Other benefits of MaMi include the extensive use of inexpensive low-power components, reduced latency, simplification of the multiple-access layer, and robustness to interference. The drastically reduced emitted RF power can reduce the total energy consumption of a mobile network, when implemented with simple, low power hardware developed in MAMMOET. Consequently, MaMi can, with proper system design, facilitate entirely new deployment scenarios, with wind or solar powered base stations. MAMMOET will substantially contribute to the development of practical MaMi systems and secure a leading position for European industry in its exploitation. Specifically, MAMMOET will investigate the practical limitations of MaMi, and develop complete technological solutions leveraging on innovative low-cost and drastically more efficient and flexible hardware.The academic and research institute partners in MAMMOET include pioneers in MaMi and groups with extensive experience in circuit design for wireless communications. The industrial partners are leaders in their fields and cover the entire chain from component manufacturing to system development and service provisioning.
