- Editorial contextDOCOMO puts radio supplier choice into commercial operation, The Japanese operator has connected multiple vendors' radios to newer Nokia baseband equipment. The commercial value lies in sustaining those choices through upgrades, not merely declaring an open interface.Medium confidence
- Editorial contextUser-level AI-RAN needs an error ledger, not one average, DOCOMO and Samsung report that simulated user-level optimisation cut throughput-degradation frequency from 13.1% to 7.2%. The result is promising; commercial control depends on who improved, who was incorrectly changed, what other users lost and how the network rolls back.Medium confidence
- Editorial contextDOCOMO's 2028 satellite roadmap needs a service envelope, DOCOMO has contracted for a satellite layer intended to add voice, faster browsing and IoT during fiscal 2028. The roadmap is strategically significant; its operating value will depend on published limits for capacity, latency, priority, device certification and fallback.Medium confidence
- Editorial contextMarunouchi makes real estate the control plane for mmWave, DOCOMO and Mitsubishi Estate want to build a dense 5G cluster across one of Tokyo's busiest business districts. The partnership addresses mmWave's hardest constraint: radios only work where property access, sightlines, fiber, power and streetscape approval meet.Medium confidence
- Editorial contextNTT DOCOMO's AI-RAN result cuts a simulated failure rate, not yet a live network problem, Samsung Electronics and NTT DOCOMO report that user-level AI optimisation reduced the frequency of communication-speed degradation from 13.1% to 7.2% in a January simulation using data from a commercial network and a 5G test network. The 5.9-percentage-point change is an approximately 45% relative reduction, but commercial-network data is not the same as live autonomous control.Medium confidence
- Editorial contextDOCOMO’s 6.5 million satellite connections measure reach, not revenue, NTT DOCOMO says 6.5 million people have connected to its direct-to-device Starlink service since late April. The number is meaningful evidence that satellite fallback is reaching ordinary handsets; because access is free and requires no application, it is not a subscriber, usage or monetisation metric.Medium confidence
- Editorial contextDOCOMO’s Ericsson choice moves the RAN bottleneck into compute, NTT DOCOMO has selected Ericsson RAN Compute as a baseband platform spanning 4G, 5G and 5G-Advanced. The decision matters because radio capacity is increasingly governed by processing, pooling and software lifecycle as well as antennas. Ericsson says the new generation can provide up to twice the capacity of its predecessor while using less than half the energy. Those are vendor comparisons, not measured results for DOCOMO’s network, and the public report does not disclose how many units will be deployed or when.Medium confidence
- Editorial contextNTT Docomo's 2021 Network Switchback Outage Made Mobile-Core Capacity an Accountability Test, NTT Docomo's nationwide mobile-network disruption on 14 and 15 October 2021 began during a migration of an IoT subscriber and location-information server. When trouble appeared on the new equipment, the operator switched the population back. The return generated a mass of location-registration signals, exhausted shared signalling-switch resources, and spread congestion beyond the IoT platform into ordinary voice and data service. The incident showed why a rollback cannot be judged by whether old equipment is active again. It must be judged by the state that millions of endpoints, shared control-plane resources, and customer services enter after the reversal.Medium confidence
