Samsung has started to publicize its direction for 6G, the next generation of wireless networks likely to supercede 5G sometime in the next decade. The company joins Nokia and a few other organizations that are exploring the upgrade.\n\n5G resources\n\nWhat is 5G? Fast wireless technology for enterprises and phones\nHow 5G frequency affects range and speed\nPrivate 5G can solve some problems that Wi-Fi can\u2019t\nPrivate 5G keeps Whirlpool driverless vehicles rolling\n5G can make for cost-effective private backhaul\nCBRS can bring private 5G to enterprises\n\n\nConnected machines and artificial intelligence will feature prominently in future use-cases, as will digital twins, hi-fi mobile holograms and immersive extended reality (XR), the company says in a white paper.\n6G features will include better spectral and energy efficiency and a requirement for trustworthiness that, \u201caddresses the security and privacy issues arising from the widespread use of user data and AI technologies,\u201d Samsung says in an associated news release.\n\nFaster data rates\nFrom a technology standpoint, Samsung says it will be aiming for peak data rates of 1Tbps and latency less than 100 microsec, "fifty times the peak data rate and one-tenth the latency of 5G." 6G will use terahertz frequencies, which are well above microwave and millimeter wave, along with optimized antennas. Spectrum sharing enhancements and more sophisticated duplexing will be used to better utilize wireless frequencies, Samsung says.\nReliability also is mentioned as a focus. But it\u2019s the projected megatrends that Samsung says will propel 6G that are most interesting.\n6G will connect machines\nWhile legacy products like voice may still be a feature, it will be vehicles, robots, construction machinery and factory equipment that will become prime \u201cconnected machine\u201d users. \u201cSmart sensors installed in various infrastructures\u201d will be a part of that, Samsung says.\nIn terms of new use-cases, Samsung thinks that a combination of virtual reality, artificial reality and mixed reality called XR will be set in motion by 6G. Roadblocks to XR include hardware limitations, in particular processing power, and battery performance, but also wireless capacity. Samsung thinks 6G will solve these issues. An example: AR alone needs 55.3 Mbit\/sec to support 8K displays, Samsung says, and XR needs even more.\nWith enough bandwidth, holograms could display gestures and facial expressions in real time, but with a peak data rate of 20Gbps, 5G is too slow, Samsung says. Holograms of 19.1 gigapixels, for example, require 1Tbps throughput, which would be Samsung 6G's top speed.\nDigital twins, too, could enter mainstream usage with 6G, Samsung says. Industrial uses could include detecting problems in sensors remotely. \u201cA user could physically move within a remote site by controlling a robot in that space entirely via real-time interactions with a digital-twin representation of that remote site,\u201d Samsung says.\n\u201cIncreasingly, machines will need to be connected by means of wireless communications,\u201d Samsung says.
