While 5G mobility promises a huge advance in mobile technology, in reality, 5G represents a number of separate
but interrelated advances that provide new capabilities to further the progress made in increasing network speeds.
Five key technologies underpinning 5G NR are millimeter wave spectrum, small cells, massive multiple input
multiple output (massive MIMO) base station antennae, beamforming, and full duplex communications.
5G will enable vast increases in the number and types of connected devices (both low and high power) and new
types of networks with varying requirements (e.g., vehicle-to-vehicle networks, virtual reality over mobile, and
mobile industrial automation networks). But 5G also enables new exploitation scenarios from adversaries
leveraging the Internet of Things (IoT).
