AI, Open RAN and sustainability—Fujitsu on key themes of MWC


AI-driven community operations will cut back opex, streamline efficiency monitoring and improve operator agility

Fujitsu expects to see an acceleration within the tempo of Open RAN (O-RAN) deployments this yr and a consolidation when it comes to industrial deployments in 2025, in response to Patrick Eriksson, vice chairman and international head of radio unit enterprise at Fujitsu.

“I feel it [O-RAN] began fairly nicely with a few greenfield operators that did pretty giant deployments. After that, O-RAN deployments halted a bit of bit after which this step to come back into brownfield deployments has been a bit of bit difficult to take. I feel, from our perspective, what we’re seeing…proper now’s we consider issues will occur this yr, and are available to fruition…perhaps in 2025 and onwards,” he defined throughout a current interview with RCR Wi-fi Information at Cellular World Congress in Barcelona.

Given the parallel pushes for opex discount and progress in opposition to net-zero targets, Eriksson additionally highlighted how Fujitsu is approaching power effectivity (and attendant prices) on the hardware-level, and likewise primarily based on an understanding of actual world community demand.

“One is the uncooked {hardware} effectivity that we’re working with. And right here we’re using, for example, gallium nitride energy amplifiers (PAs) all through our complete portfolio. Along with that, we’re additionally deploying proprietary PA architectures and power effectivity algorithms which can be serving to to enhance our general energy effectivity on the {hardware} aspect… we even have the options that optimize the facility effectivity in accordance with the precise site visitors load of the radio,” he mentioned.

Utilizing AI for community root-cause evaluation and predictive upkeep

Fujitsu can also be utilizing synthetic intelligence (AI) to develop new instruments to assist operators enhance community efficiency. Throughout Cellular World Congress, Greg Manganello, senior vice chairman at Fujitsu, defined the principle options of the Alarm Storm Detector software developed by Fujitsu utilizing AI.

Alarm Storm Detector is an AI/ML-powered software engineered to streamline community efficiency monitoring. “Now we have mixed our community operations data with AI to essentially assist community efficiency. And when there’s a community bother, what we actually realized is that it’s not a low stage of bother, however huge spikes, which is usually a little bit overwhelming to community operations groups. And we realized they’ve been spending days and weeks in search of the foundation trigger. So utilizing our AI instruments, we will discover the precise root reason for a community bother, throwing away lots of and 1000’s of spinoff alarms and attending to the foundation trigger,” mentioned Manganello.

“The following step that we’re engaged on proper now to launch is predictive upkeep. So after we detect degradation of community parameters, we already current that to the operator,” he added.

Manganello additionally famous that Fujitsu is at present engaged on giant language fashions—a kind of a chat GPT interface for community operators—, taking a look at log information and big petabytes versus of information, after which serving to the community operator question that database.

“However what we understand is LLM can’t function on all that uncooked information. So we invented a brand new type of AI known as computerized data extraction, which actually is sort of a bridge between all that multi-vendor multi-domain information, after which community operators to allow them to get the solutions again to their questions on how you can actually function a community extra effectively,” he mentioned.
