SKT claims Open RAN digital base station developments


SKT says it has improved the facility consumption and processing capability of digital base stations

Korea’s SK Telecom (SKT) is claiming developments within the energy consumption and processing capability for Open RAN digital base stations, ensuing from its work with a number of trade companions together with Samsung, Ericsson, Nokia and Intel.

The service’s interconnection exams have been carried out utilizing digital base station outfitted with a built-in accelerator. One check was performed with Ericsson and Samsung, and one other was performed with Nokia. Intel partnered with SKT on an AI-based digital base station, which the service mentioned will allow the flexibility to foretell visitors patterns and effectively management the on/off operation of every CPU core of the digital base station server, leading to a reductino of greater than 20% in energy consumption.

In line with SKT, capability good points and energy utilization discount are the first technical challenges when it coeds to transitioning to Open RAN digital base stations.

“It is a significant analysis and growth (R&D) achievement that improved each the facility consumption and processing capability, that are vital in open LAN digital base stations,” mentioned Ryu Tak-gi, who oversees SKT infrastructure expertise. “The corporate believes that the digital base station will turn out to be the baseline for development of 5G and 6G networks and can proceed to make headways in analysis and growth.” 

Final 12 months, SKT and Nokia demonstrated the method of virtualizing the baseband based mostly on Nokia’s design, together with its complete infrastructure options reminiscent of NADCM (Nokia AirFrame Information Middle Supervisor), separating {hardware} and software program, and working every independently. Specifically, the pair examined the community flexibility and efficiency on the similar time by dividing the infrastructure into two separate features: a cloudified digital distributed unit (vDU) and a digital central unit (vCU). On the time, each firms acknowledged the the trial confirmed the agile response of 5G vRAN to computing necessities reminiscent of excessive efficiency, massive capability and the potential of quickly launching new companies.
