Multiple Inputs and Multiple Output Based Concepts

n radio, multiple-input and multiple-output, or MIMO (pronounced /ˈmaɪmoʊ/ or /ˈmiːmoʊ/), is a method for multiplying the capacity of a radio link using multiple transmit and receive antennas to exploit multipath propagation.[1] MIMO has become an essential element of wireless communication standards including IEEE 802.11n (Wi-Fi), IEEE 802.11ac (Wi-Fi), HSPA+ (3G), WiMAX (4G), and Long Term Evolution (4G). More recently, MIMO has been applied to power-line communication for 3-wire installations as part of ITU G.hn standard and HomePlug AV2 specification.
