The South Korean tech firm Samsung has recently announced the next phase of its 5G vRAN. They said that they are bringing next-level capabilities for its virtualized RAN (vRAN), which will improve its performance and increase the rate of power saving. The South Korean firm has also said that they will launch vRAN 3.0, the next phase of 5G vRAN technology, by the fall of this year.
Let us inform you the new update of Samsung’s cloud-based automation system for large-scale vRAN is now available in Asia, Europe, and North America. Specifically, the Samsung Cloud Orchestrator (SCO), which automates the lifecycle management of large-scale vRAN, has received an upgrade. It also got the support of the automation of vRAN deployment of private and public, both cloud networks.
What new the new vRAN 3.0 5G technology will bring
Let us inform you the new 5G vRAN 3.0 technology will bring improvements in two fields- Performance Optimization and Power Savings. Let’s take a look at them.
In terms of performance optimization, Samsung has made improvements in cell support and modem algorithm. With a software update, vRAN will get the ability to provide 3 Cell configuration of 200MHz bandwidth support. To make it possible, it will use its 64T64R Massive MIMO radios, which is more than the triple of previous generation software. It is capable of supporting an entire mid-band 5G spectrum holding of an operator.
Apart from this, Samsung is also incorporating a modem algorithm optimization approach for developing its roadmap. This approach lets the operator receive software fitted to their needs. The software will have the required features and configurations only, which allows an optimized and efficient use of COTS servers.
To deliver better power-saving capabilities, the company has made quite a few changes and improvements, which specifically are- CPU Core Sleep Mode, Adaptive Core Allocation, and Energy Saving Feature Orchestrator (ESFO). All these three features will help to reduce power consumption and lead to an increment in power saving. So, let’s keep an eye on them.
First, the CPU Core Sleep Mode, which is available on Sammsung’s vRAN software, will reduce power consumption. To make it possible, this mode will automatically put the CPU in sleep mode and turns the unused CPU cores off when the device is in low data traffic. Sleep mode will be undone, and the CPU will be back to normal when needed or when the capacity demand increases.
The second Adaptive Core Allocation feature enables 5G vRAN 3.0, which will assign several CPU cores relevant to the number of active cells. For even more power consumption, it sets unassigned or unused CPUs to idle mode, so they can not absorb power. And exactly like the CPU Core Sleep Mode, the CPU and its cores get back to normal wherever the capacity demand increases.
The last Energy Saving Feature Orchestrator (ESFO) does the work of a manager. It manages multiple energy-saving features and optimizes efficiency without any service interruption. Informatively, it analyzes hourly traffic patterns and optimizes the operating conditions of the Energy Saving feature according to sector and time zone. Its tools constantly update multi-level Energy Saving operations of multiple features.
As per the official Newsroom blog post, the new vRAN capabilities will make their way to global operators, and the beginning will be in North America; the update will roll out here in the first half of the year 2023.
