Samsung’s new radios will help accelerate operators’ 5G rollouts in mid-band spectrum. Mid-band frequencies deliver a combination of wide coverage, high speeds and low latency. Operators can also use this solution for RAN sharing, where they actively share network infrastructures with other operators through joint deployments. This includes when an operator owns non-contiguous frequencies within 400MHz of bandwidth. The new technology will help operators minimize the number of radios required when managing spectrum in various deployment scenarios. With wider bandwidth support, Samsung’s radios will help operators maximize the utility of their mid-band spectrum for 5G networks, while using less hardware. With this new technology, Samsung will extend the bandwidth support of its 5G radios to 400MHz-double the 200MHz supported by its current commercial radios. Samsung Electronics has developed a new 5G wideband radio technology that expands bandwidth support for its next generation radios, including Massive MIMO radios, to help operators drive more flexible and cost-effective 5G deployments.
5G SPECTRAL EFFICIENCY SOFTWARE
More 5G clients talking to more antennas means more complexity, and the networks are using software to analyze and manage both, he said.New Samsung technology doubles bandwidth support of its mid-band portfolio, helping operators minimize hardware needs and simplify 5G rollouts The idea is to make the networks themselves smart enough to handle that complexity, said Kindness. The need for AI/ML support in networks is a product of increased network complexity, and represents a logical outgrowth of technologies like software-defined networking in the unlicensed wireless sector. On the operational side, there are several ways improved integration of AI/ML should help networks function, according to Tseng, “things like better handoffs, more spectral efficiency, even more accurate positioning,” he said. AI/ML improvementsĪI and machine learning apply to 5G on both a network management level and a capability level that is, AI/ML is both a tool for improving how networks operate and an application that 5G networks are designed to support.
5G SPECTRAL EFFICIENCY FREE
The new reduced-capability spec can keep more bandwidth free for more intensive applications and help answer the question, “How do we make sure more devices can be more efficienctly supported in the networks?” he said. Wearables and certain types of sensors fall into this category, according to Tseng. That’s much simpler than architecting and deploying their own networks to support the IoT initiative.Īn important part of the new IoT support builds on a feature introduced earlier called reduced capability that can provide 5MHz channels for devices that need more than the 200kHz that narrow-band IoT can provide but less than the smallest channel defined in the previous 3GPP specification-20MHz. If a commercial 5G service is available where customers wants to network IoT, all the customers need to do is ensure their IoT endpoints support the service and turn it on. Using 5G networks to support IoT deployments appeals to carriers because of its potential popularity. “Analysis of packets coming back on each antenna, filtering signal/noise-it’s the next level of that.” IoT support “It’s on the client side, as well as the radio side,” said Kindness. This lets wireless networks use the same spectrum to connect to multiple clients at once without creating interference, as a client located in one direction relative to an access point can be serviced via the same bandwidth as one located in a different direction. The key new MIMO spec is for beamforming-sending radio signals directionally instead of in an omnidirectional broadcast, according to Forrester principal analyst Andre Kindness. Hence, a MIMO-enabled system can service a large number of client devices at the same time using less spectrum by allowing each client to communicate via a different antenna.
Multiple-input, multiple-output (MIMO) technology is a cornerstone of advanced wireless communication in both the licensed and unlicensed worlds, letting single access points or base stations use spectrum much more efficiently by automatically coordinating the operation of multiple antennas on each access point.
