450 MHz Alliance Conference Concludes in Jakarta with Industry Alignment on Spectrum's Role in Future-Ready Critical Communications

A consistent thread ran through the agenda: the 450 MHz band is no longer being framed as a complementary or transitional asset.

The 450 MHz Alliance Conference closed in Jakarta this week after three days of strategic discussion that brought together Alliance members, network operators, regulators, vendors and ecosystem partners to chart the next phase of secure, resilient and long-term private communications networks built on the 450 MHz band. Hosted and sponsored by Nokia, the event served as a focal point for the global community working to position the band as a cornerstone of modern mission-critical connectivity for utilities, public safety and other critical infrastructure operators.

A consistent thread ran through the agenda: the 450 MHz band is no longer being framed as a complementary or transitional asset, but as a foundational layer for private wireless networks that must remain dependable for decades. Sessions on spectrum strategy and regulatory developments were paired with discussions on ecosystem expansion and the device roadmap, reinforcing the Alliance's view that long-term certainty around spectrum allocation, harmonisation and supporting technology is essential if utilities and critical infrastructure operators are to commit to deployments at scale.

The second day of the conference opened with a welcome address and industry update from the Alliance leadership, followed by a presentation from Indonesia's Ministry of Communication and Digital Affairs (KomDigi) on the country's wireless and spectrum strategy — providing a fitting national context for the Jakarta-hosted gathering. The day's programme then turned to dedicated networks for critical services, examining spectrum planning, business models, and the perspectives of both operators and suppliers. A central moment came with the introduction of the joint ADL and 450 MHz Alliance white paper, "The Spectrum Phoenix", which sets out the strategic case for the band's renewed role in supporting mission-critical communications.

MCPTT, MCX and Field Experience

The afternoon featured an extended deep dive into MCPTT and MCX, covering network infrastructure, end devices and go-to-market readiness, before closing with a panel on real-world MCX deployment experience. Further sessions examined new products and field results, including underground NB-IoT experiments, early deployment learnings from operational networks, cross-border interference coordination, and the introduction of a CIGRE paper relevant to the utility sector. The day concluded with a networking dinner that extended discussions well into the evening.

From Private LTE to 6G and NTN

Across the full programme, technical content centred on the deployment of Private LTE and Private 5G networks for utilities and critical infrastructure, with case studies presented from networks already in operation. Discussions extended into mission-critical services delivered over the band, including MCPTT and broader MCX deployments, alongside forward-looking sessions on 5G RedCap, 6G and Non-Terrestrial Networks (NTN). The combined content illustrated how today's commercial deployments and tomorrow's emerging standards can coexist within the same spectrum strategy, provided that regulatory frameworks and the device ecosystem evolve in parallel.

Regulators and Operators in Direct Dialogue

Participants, including NETFI and a wide cross-section of operators, vendors and partners, described the event as a productive environment for exchanging operational experience and shaping common positions. Workshops and panel discussions complemented the formal presentations, with attendees noting the value of direct engagement between regulators and the operator community in clarifying spectrum policy direction and accelerating deployment timelines.

From Alignment to Action

The clear outcome of the Jakarta conference was a shared commitment to translate alignment into action. Alliance members and partners signalled their intention to advance regulatory harmonisation efforts, expand the device and chipset ecosystem supporting the band, and accelerate collaboration on real-world deployments for utilities and critical infrastructure. With the publication of "The Spectrum Phoenix" white paper and consensus reached on the strategic role of 450 MHz in the future critical communications landscape, the focus now turns to converting the momentum built in Jakarta into concrete progress on networks, devices and cross-border coordination in the months ahead.
