Semtech Corporation has announced the launch of a cellular–satellite Internet of Things (IoT) platform developed in partnership with Skylo Technologies. The integrated service combines terrestrial and satellite connectivity to provide a unified device-to-cloud solution that automatically switches between networks when IoT devices move beyond the range of cellular towers.

The platform allows users to deploy IoT devices globally under a single subscription and a single Subscriber Identity Module (SIM). It is designed to simplify network management for industries requiring uninterrupted data transmission, such as logistics, energy, agriculture, and infrastructure monitoring.

According to Skylo Technologies, Semtech is the first company to deliver Skylo-certified modules with integrated network access. The integration of Skylo’s satellite network directly into Semtech’s Smart Connectivity platform enables users to adopt non-terrestrial network (NTN) IoT services with the same operational simplicity as traditional cellular solutions.

The service uses Semtech’s HL7810 low-power wide-area (LPWA) module, which supports LTE-M, NB-IoT, and NTN connections. A second version, the HL7812, adds 2G fallback capability. Both modules connect to Semtech’s Smart Connectivity Premium SIM, providing access to more than 600 partner networks operating on 4G LTE, 5G, and Skylo’s satellite NTN.

The combined system enables IoT devices to maintain continuous communication even when crossing between terrestrial and satellite coverage zones. It is being evaluated by selected customers ahead of a planned general release in November 2025.

The initiative reflects a broader trend toward the convergence of terrestrial and satellite networks within the IoT sector, aimed at supporting worldwide coverage for asset tracking, agriculture, infrastructure, and other critical communications services.

Shared-Spectrum D2D Model Aims for Open Access

A new approach to direct-to-device (D2D) connectivity proposes satellites as shared infrastructure—much like terrestrial cell towers—coordinated by a shared spectrum D2D ecosystem rather than a single vertically integrated player. The concept aggregates mobile satellite spectrum already allocated across scores of markets, aiming to deliver consumer-grade messaging first, then data services, within a three-year window.

Under this model, multiple participants contribute spectrum while retaining ownership, with operations orchestrated to maximise regional availability and uphold national sovereignty. Technically, the blueprint combines in-orbit assets with new Low-Earth Orbit capacity, stitching them through common standards and interoperable gateways. The draw for policymakers is clear: an open framework that lets countries and spectrum holders participate on equitable terms without ceding control.

For the wider market, shared access reduces duplication and lowers the barrier to entry for mobile network operators, chipmakers, device OEMs, and app providers. Adoption hurdles remain—while 3GPP now includes several MSS bands, handset support is still concentrated in higher-end models—but a phased service plan (starting with SMS/MMS and short media, expanding to IP data) can ramp usage as device compatibility broadens.

The industrial upside is immediate. Infrastructure and IoT estates gain resilient, standards-based fall-back for telemetry, alarms, and control where terrestrial reach is patchy. Disaster Recovery teams benefit from an on-ramp that works on ordinary smartphones, enabling coordination when fibre and cellular fail. Maritime corridors, remote workforces, and transport routes can all exploit ubiquitous coverage without bespoke satellite handsets.

Success hinges on governance as much as radios. Clear rules for spectrum coordination, lawful intercept, roaming, and interference mitigation are essential, alongside common APIs for provisioning, billing, and network slicing. Security baselines must cover device attestation, fraud controls, and end-to-end encryption, while performance SLAs should reflect realistic capacity during surge events.

If executed well, the architecture could complement national strategies seeking vendor diversity and sovereign control, while accelerating handset-native satellite capability across the ecosystem. With timelines ambitious and details still emerging, the prize is a more inclusive market—one where multiple providers interoperate on shared infrastructure inside a shared spectrum D2D ecosystem.

IRIS2 Sovereign Satellite Network Needs Faster Delivery

Europe’s next flagship satcom programme is moving from concept to execution under pressure to deliver sooner and scale smarter. Speakers at a recent defence and security forum stressed that the IRIS2 sovereign satellite network must arrive quickly, with security monitoring, anti-jamming resilience, and cyber-hardening baked in from day one. The goal is clear: a multi-orbit, software-defined platform that can flex capacity and assure priority access for government users while catalysing commercial services.

Authorisation and governance will matter as much as hardware. A PPP structure is intended to couple public oversight with private agility, but timelines must compress to match a more contested domain. Officials underlined sovereignty: assured access, European data protection, and continuity of service during crises. Practically, that means secure terminals, scalable gateways, and a security monitoring structure—not just a single centre—to detect and respond to threats in real time.

Operationally, IRIS2 is expected to stitch together legacy assets with new payloads, enabling rapid tech insertion rather than five-year refresh cycles. This approach supports mission types where latency, availability, and integrity are critical: connecting embassies, ministries, and deployed forces; backing civil contingency routes; and providing surge capacity when terrestrial links are compromised.

Industry use-cases are equally prominent. For Infrastructure and IoT, a European-controlled backbone can carry telemetry and control traffic with predictable performance and clear chain-of-custody—essential for utilities and smart-grid operations. In Disaster Recovery, pre-provisioned terminals and priority slices can restore communications within hours, enabling situational awareness, logistics coordination, and public alerts even amid spectrum interference and damaged fibre.

Critics warn of arriving late or undersizing the constellation. Policymakers counter with a design philosophy centred on scalability: start complete, then expand satellites, beams, and services as demand and budgets grow. The emphasis is on interoperability (LEO/MEO/GEO), secure routing, and agile ground integration so capacity can be steered where it is needed most.

The message from European institutions and programme leaders is consistent: accelerate procurement, iterate in orbit, and keep sovereignty at the core. Delivering a resilient, upgradeable platform will determine whether Europe can guarantee secure access and competitive services at pace—and fulfil the promise of the IRIS2 sovereign satellite network.

Agile MEO ‘Network-of-Networks’ Sets New Satcom Pace

An agile, software-defined ‘network-of-networks’ in Medium-Earth Orbit is being built to merge existing assets, European programmes, and next-generation satellites into one flexible platform. This software-defined agile MEO network will replace five-year waterfall cycles with rapid, iterative insertion of new technologies, validated on multiple pathfinder missions each year across varied orbits and altitudes before scaling to production.

At its core are software-defined payloads, optical inter-satellite links, and dynamic resource orchestration that move capacity, beams, and waveforms to where demand appears. Decoupling hardware cadence from service evolution reduces CapEx risk, trims time-to-market, and avoids stranded capacity. Continuous ‘test–learn–deploy’ loops shorten feedback cycles and let the platform respond in weeks rather than years.

Pathfinder flights scheduled from 2026 will exercise new components on-orbit, verify autonomy, and benchmark performance at different altitudes. Results will flow straight into software roadmaps and ground integration, informing production designs without pausing service. Open interfaces and Digital IF at the gateways let operators graft the new layer onto existing GEO and LEO estates without forklift swaps.

For Aviation, that means smoother handoffs along busy corridors, policy-driven quality of service for safety communications, and bandwidth that can be steered dynamically to aircraft cabins. For Maritime, steadier throughput on blue-water routes supports bridge operations, crew welfare, IoT telemetry, and mission-critical workflows, even under rough weather or contested spectrum.

On the ground, modular digital gateways standardise building blocks—frequency converters, RF-over-fibre, matrices, amplifiers, and BUCs—while virtualised switching, spectrum management, and monitoring run over IP. This hybrid model enables sovereign deployments, simpler upgrades, and multi-orbit orchestration. Programmes can pace launches to proven demand, scaling capacity and spend without betting on monolithic fleets. It also eases compliance, centralising audit trails, role-based access, and incident reporting while improving spectrum hygiene and interference resolution across widely distributed gateway estates globally.

Partnerships are baked in: agile manufacturing for rapid pathfinders, optical subsystems for higher-rate links, and automation software for end-to-end control. The outcome is a living platform that upgrades in software, validates quickly on orbit, and scales prudently with market need—a practical route to faster features, smarter CapEx, and service agility delivered by a software-defined agile MEO network.
