An available spectrum is divided into M sub-bands, with each of the M sub-bands having N beams. The system, through using M×N available beams, can maintain frequency domain and spatial domain orthogonality. A method includes receiving a direction indicating a location of a device relative to a transmitter and selecting a beam from the M×N beams. The beam can be a data beam for transmitting data to the device or a null to suppress interference. The bandwidth, spectrum and/or direction associated with the beam can be chosen and/or varied based on one of any number of parameters such as avoiding channel distortions, reducing mismatch in amplitude and/or delay, and adapting to a data type or data amount. Frequency assignments can be staggered through a cell-based region to reduce cell interference in assigning beams."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for spatial on sub-band massive MIMO/BFN to provide a large number of orthogonal channels","description":"Systems, methods, and computer-readable storage devices relate to a process for beamforming in a system.
