  • NTT DOCOMO and Nokia Launch Multi-Vendor O-RAN Base Station Platform

    NTT DOCOMO and Nokia Launch Multi-Vendor O-RAN Base Station Platform

    NTT DOCOMO began commercial operations on September 9 for a multi-vendor base station platform built on open radio access network standards in Japan.

    The deployment allows DOCOMO to combine Nokia base station equipment with O-RAN-compliant radio units supplied by different vendors across LTE and 5G networks.

    DOCOMO deployed Nokia AirScale equipment incorporating Levante data-processing and Ponente control-processing technologies to handle more radio units while reducing power consumption.

    Hardware Details and Power Savings

    This updated equipment handles more radio units per site than DOCOMO’s previous Nokia gear while drawing less power. Lower electricity demand directly reduces operating costs across dense urban grids where base station density is highest.

    Under open interface specifications, engineers can pair the central processing base with high-power transmitters for suburban coverage or compact transceivers for city spaces. DOCOMO uses this modular mix to adjust capacity without replacing full base station stacks.

    Multi-Vendor Flexibility in the Field

    Japanese mobile operators have adopted open architecture faster than carriers in North America or Europe. By ending single-supplier reliance on base stations and antennas, DOCOMO forces vendors to compete on unit price, form factor, and power efficiency.

    Field maintenance and troubleshooting carry the main technical risks. Coordinating software upgrades and diagnosing network faults across hardware from different vendors creates operational friction that proprietary setups avoid.

    High-Density Event Deployments

    On September 12, the carrier brought the multi-vendor setup into field service at the 59th Joso Kinugawa Fireworks Festival. DOCOMO mounted the platform inside a mobile cellular vehicle, pairing it with Nokia Dual Boost Massive MIMO hardware to handle surges in data uploads and voice traffic.

    Engineers plan to expand the base station architecture nationwide. Initial site conversions will focus on metropolitan sectors, stadiums, exhibition centers, and outdoor entertainment venues where mobile traffic spikes.

    Roadmap to Autonomous Networks

    Work on the rollout stems from a technical memorandum of understanding DOCOMO and Nokia signed on August 12. That agreement established joint trials for virtualized radio access networks, cloud infrastructure, and AI-directed network management systems.

    Joint testing now focuses on running Self-Organizing Networks and RAN Intelligent Controller automation tools across mixed-vendor hardware fleets as DOCOMO prepares its transmission grid for 5G-Advanced and early 6G standards.

  • One New-Zealand and 2Degrees Form Joint Entity to Share Mobile RAN Infrastructure

    One New-Zealand and 2Degrees Form Joint Entity to Share Mobile RAN Infrastructure

    One New Zealand and rival operator 2degrees will merge their mobile radio access network infrastructure into a jointly owned venture, pooling physical assets across the country.

    The agreement consolidates towers, antennas and base station equipment from both carriers into a single operational entity while keeping retail operations and core networks separate.

    Pooling Capital and Network Sites

    Under the planned arrangement, the two carriers will run their shared radio access network (RAN) through the new entity to cut duplicate capital expenditure and accelerate the rollout of newer wireless standards. Combining site portfolios expands coverage reach and deepens network redundancy without requiring each carrier to build standalone duplicate towers across challenging topography.

    Shared infrastructure models have gained traction across Asia-Pacific as regional operators face elevated spectrum costs and heavy 5G capital requirements. In markets like Australia and Malaysia, regulators and telcos have turned to shared active networks and wholesale single networks to protect cash flow while meeting coverage mandates.

    Operational Focus and Regulatory Steps

    One NZ indicated the structural separation allows both operators to redirect capital toward customer-facing platforms, core network features and digital services rather than tower hardware. Both companies will continue to market their mobile plans independently and compete for subscriber share across consumer and enterprise segments.

    The transaction remains subject to formal regulatory reviews and commercial approvals in Wellington before the joint business begins operational integration.
