Is massive MIMO used in 4G?
It is called Massive Multi-Input Multi-Output (MIMO) radio. Massive MIMO has been playing a critical role in 4G and 5G networks for many years, and expected to increase its influence even more.
Why MIMO is used in 4G?
LTE uses MIMO for transmit diversity, spatial multiplexing (to transmit spatially separated independent channels), and single-user and multiuser systems. MIMO in LTE enables more reliable transmission of data, while also increasing data rates. It separates the data into individual streams before transmission.
What is difference between massive MIMO 5G and 4G?
With 5G cellular, a new massive MIMO will boost bandwidth to users and support more users per antenna by incorporating a larger array of smaller antennas. Today's 4G MIMO uses frequency division duplex (FDD) to support multiple devices, while 5G massive MIMO will use a different scheme, time division duplex (TDD).
What is MU-MIMO in LTE?
Multi-user MIMO (MU-MIMO) is a set of multiple-input and multiple-output (MIMO) technologies for multipath wireless communication, in which multiple users or terminals, each radioing over one or more antennas, communicate with one another.
