Massive MIMO Vs Traditional MIMO

Key Definitions and Concepts

To grasp the differences between Massive MIMO and traditional MIMO, it's essential to first understand the foundational concepts:

• MIMO (Multiple Input, Multiple Output): A wireless technology that uses multiple antennas at both the transmitter and receiver ends to improve communication performance. Traditional MIMO typically employs a limited number of antennas, such as 2x2 or 4x4 configurations.

• Massive MIMO: An advanced version of MIMO that leverages a significantly larger number of antennas—often in the range of hundreds—at the base station. This enables simultaneous communication with multiple users, dramatically enhancing network capacity and efficiency.

• Beamforming: A signal processing technique used in both traditional and Massive MIMO to direct signals toward specific users, reducing interference and improving signal quality.

• Spectral Efficiency: A measure of how efficiently a given bandwidth is utilized. Massive MIMO offers significantly higher spectral efficiency compared to traditional MIMO.
