サムスンはMassiveMIMOの30％ブーストを売り込みます

サムスンは、ベンダーが4Gおよび5G環境でネットワークスループットを最大30％向上させることが期待されていると述べている、MassiveMIMO無線の新技術を売り込んでいます。Samsung is touting new technology for its Massive MIMO radios that the vendor says is expected to enhance network throughput by up to 30% for 4G and 5G environments.  Dubbed Mobility Enhancer, the newly developed tech uses advanced signal processing and AI to improve beamforming accuracy from Samsung’s Massive MIMO unit toward users on the go - for example, a 5G consumer walking down the street. The 30% performance boost was experienced by a walking mobile user during a field trial performed at Samsung’s own testbed. Samsung expects to add the new tech to its Massive MIMO radios via software upgrade that will be available globally this year. “At Samsung, our goal is to deliver the finest network solutions to mobile operators of all kinds, enabling them to provide their customers with the highest quality, most immersive mobile experience possible,” said JeongHo Park, VP and head of Advanced System Design Lab, Networks Business at Samsung Electronics, in a statement. “Mobility Enhancer is one of the key advancements we are working on to innovate mobile networks, and help advance 5G performance to the next level.” Massive MIMO (Multiple Input, Multiple Output), helps coverage and capacity with sub-6 GHz spectrum, and the South Korean vendor uses 3D beamforming, with vertical and horizontal beam directions, to improve data rates. A large number of antenna elements for Massive MIMO handle multiple data channels at the same time for beamforming, enabling the ability to send targeted, pin-pointed beams to different devices simultaneously with less interference. Earlier this year at CES Samsung put array antenna beamforming in the spotlight for millimeter wave 5G as part of its work to equip vehicles with 5G-capable telematics control units. As for Massive MIMO radios, its portfolio includes units for 3.5 GHz, 2.5 GHz, and Citizens Broadband Radio Service used in the U.S. – the latter which is still in the process of obtaining OnGo certification. Samsung isn’t the only vendor with network announcements this week. Ericsson just yesterday unveiled three new mid-band radios for 5G, including its Massive MIMO and RAN compute portfolios. The Swedish vendor called out the importance of beamforming, and Ericsson silicon enabling more processing for real-time channel information.      Nokia, meanwhile, on Tuesday launched new 5G core deployment services, its DelOps (Delivery and Operations) initiative, with new 5G core services meant to reduce network complexity.
