5G TERMS AND ACRONYMS

M2M (Machine-to-Machine)

What is M2M? M2M (Machine-to-Machine) communication refers to the direct exchange of data between devices without human intervention. M2M is the precursor concept to the

Machine Type Communication

Also known as Machine to Machine (M2M), MTC refers to data communication between two entities without human intervention. Typically, this involves communication between an MTC

Massive MIMO

What is Massive MIMO? Massive MIMO equips the gNB with a very large number of antenna elements — typically 32, 64, 128, or more —

Massive MIMO (Multiple-Input Multiple-Output)

Refers to the large number of antennas in the base-station antenna array that enables multiple spatially separated users to be catered to by the antenna

MC – Multicarrier

What is MC? MC (Multicarrier) is a signal transmission technique that splits data across multiple parallel narrowband carrier signals rather than transmitting on a single
