In mobile technology jargon, MIMO stands for Multiple-Input Multiple-Output. It increases the speed of a radio link between a base station to a cell site and a handset. This is achieved by using multiple antennas to transmit data from the base station to several handset antennas. You may be familiar with 2 x 2 MIMO (two transmit antennas and two receive antennas in the phone) and 4 x 4 MIMO (four transmit antennas from the base station and four receive antennas from the phone). Massive MIMO places a large number of antennas on a base station to further improve network throughput.
Samsung on Wednesday announced new technology for its Massive MIMO radios that it says will increase the speed of 4G and 5G networks by up to 30%. Called “Mobility Enhancer” by the manufacturer, it uses advanced signal processing and AI to improve the accuracy of 4G and 5G signals sent from a base station to the radio in a random human’s 5G handset while ‘he walks in the street. The Massive MIMO radios produced by Samsung include models that operate with 3.5 GHz, 2.5 GHz and Citizens Broadband Radio Service (CBRS) in the United States.
Massive MIMO works with 5G signals below 6 GHz and handles multiple data channels for bundle formation. The latter is a technology used to target the transmission of precise beams to different devices simultaneously without creating interference. At this year’s CES, Samsung showcased beanforming antenna arrays for high-band 5G mmWave.
Samsung is not the only company working on such technology. Yesterday, Ericsson introduced three new 5G medium band radios incorporating Massive MIMO technology.
