Additional key elements of 5G technology include extended use of MIMO (Multiple Input Multiple Output) antenna arrays, complex implementations of beamforming technology used to pass signals more directly to end-users, and network "slicing", which is based on the transmitted Intelligent resource partitioning of services or applications. The extensive changes in technology and infrastructure inherent in 5G deployment will bring huge benefits and potential challenges to individual users, enterprises, and service providers. Operators conducting 5G speed trials reported speeds as high as 70 Gbps. Industry-initiated simulations also produced impressive results, with data speeds increased from 71 Mbps for 4G users to 1.4 Gbps (millimeter wave) for 5G users.
