Mid-Band - The intermediate part of the electromagnetic spectrum used by cellular communications, generally comprising frequencies between 1GHz and 6GHz. Sitting in between the low band and millimeter wave spectrum, it offers a balanced compromise between coverage and bandwidth, and is seen as a key band to provide broad coverage of 5G services.

Millimeter Wave (MMW) - Also known as millimeter band, are extremely high frequency radio waves typically defined in the frequency range of 30 GHz to 300 GHz.

Mobile Network Operator (MNO) - Provides wireless service(s) to wireless users by owning or leasing all components to sell and deliver wireless services over licensed wireless spectrum. MNOs include wireless service providers, wireless carriers, cellular companies, or mobile network carriers.

Multiple-Input Multiple-Output (MIMO) - Allows sending and receiving of more than one data signal on the same channel a the same time by using more than one antenna, thus improving the data rates between the transmitter and the receiver.
