Massive MIMO Radio

Samsung offers a full range of Massive MIMO Radios that support a variety of spectrums, environments and traffic requirements.

Samsung’s Massive MIMO Radios are built with many in-house components to create more efficient products. With our in-house chips and filter design, Samsung offers smaller, power efficient, powerful products. By using our beamforming SoC, the weight and volume of our products are reduced by up to 30% while power consumption is lowered by up to 15% than the previous generation. Samsung’s Massive MIMO Radios also offer natural convection cooling without fans to further reduce power requirements as well as size and weight. Natural cooling also brings down the number of site visits needed for operation and maintenance than compared to a fan-based system. Another important area of focus for Samsung is minimizing power consumption during network operation. We take a holistic approach that includes both increasing the energy efficiencies of our hardware while providing energy saving software to further reduce power consumption. For example, the Tx path of our Massive MIMO Radios are controlled to partially turn off antenna paths during non-congested times to conserve energy. With the best combination of features, Samsung can offer sustainable RAN solutions for our customers.

To enhance user experiences in various conditions and environments, Samsung is applying several advanced technologies. Samsung’s Massive MIMO Radio uses beamforming to create sharp beams that precisely target users and extends networks coverage. It also provides various beam scan range options so operators can selectively choose the best option for a certain target deployment area. It can be managed to either focus on a limited and complex area or cover a wide sparse area. Moreover, Samsung’s Massive MIMO Radio supports various beamforming modes including SRS (Sounding Reference Signal) mode, PMI (Precoding Matrix Index) mode and MU-MIMO mode, to deliver the best quality signals, no matter the mobile environment. For example, when a user device is located at the cell edge, Samsung’s Massive MIMO provides coordinated beamforming that adjusts the beam patterns of adjacent cells during SRS mode to decrease interference. To further enhance user performance in mobile environments, Samsung’s Mobility Enhancer combines AI and advanced signal processing technology to improve beamforming accuracy of a moving user. The Mobility Enhancer raises the beamforming performance of Massive MIMO Radios by up to 30% for pedestrians. Ultimately, Samsung’s best MIMO mode selection takes into account the constant changes of a user’s location, whether they are stationary, walking, or in a car, to provide the most optimized services.
