Choosing the Right IoT Network: Insights from Industry Experts

Jason Elliott, 5G Market Development Manager

Samuele Machi, Marketing Manager, 4th Industrial Revolution

ReadWrite: When we talk about IoT networking, there are many models—from mesh to large‑scale 5G deployments. Large enterprises must weigh multiple factors when selecting a network. What are the biggest concerns for executives deciding on an IoT network?

Jason: The choice hinges on the business need. Key questions include:

• Is the need immediate—within a year—or a longer‑term strategy over five years?
• Do you want to build in‑house expertise or outsource it?
• What investment model fits your budget—cap‑ex versus op‑ex?
• Will you manage the entire infrastructure or partner with a wireless provider?
• Do you require full control over spectrum, or will you lease it?

These strategic decisions guide the technology selection for each use case.

Current technologies can meet limited‑scale requirements, with the option to scale to 5G‑enabled, mission‑critical functions. Choosing the right tech for each business case—and aligning it with investment cycles—balances short‑term operational savings against long‑term revenue opportunities.

Samuele: Executives must first understand the use case. Each scenario demands a different reliability level and latency profile. For instance, tracking a parcel worldwide differs from controlling an autonomous vehicle in a factory or harbor. Identifying the exact requirement is the first step.

Next, assess the connectivity options available locally:

• Public IoT cellular (NB‑IoT, LTE‑M)
• Licensed private LTE via spectrum purchase/lease
• Unlicensed/shared LTE (Multefire, CBRS)

Finally, evaluate the ecosystem. If the technology is new, you’ll need to mobilize local partners and anticipate lead times for device and infrastructure procurement.

In summary, consider use case, connectivity, and ecosystem. Each dimension contains many sub‑factors that shape the overall strategy.

ReadWrite: Can you elaborate on the types of use cases and how networking choices might evolve?

Jason: We see the 4th industrial revolution driving transformation across manufacturing, construction, and energy sectors. A chemical plant, for example, can shift from a purely production role to a service provider—offering tailored products and real‑time analytics to customers. Flexibility in the network architecture—leveraging NFV, SDN, AI, and robust security—enables such value‑chain integration.

Samuele: Deciding between a dedicated public network segment and building your own infrastructure hinges on control and scalability. If you want to deploy devices quickly and flexibly, you might integrate the wireless layer into your IT stack, or you could rely on a carrier to manage the network.

Gaining hands‑on experience with LTE‑based technologies and edge computing today positions you to fully exploit 5G’s potential during the 4th industrial revolution.

ReadWrite: Edge computing is critical for IoT. How do energy and compute capacity factor into a network choice for executives?

Samuele: Mobile edge computing is projected to process roughly 40% of IoT data in the coming years, though current figures are still modest. Edge reduces latency, cuts transmission costs by filtering raw data locally, and enhances privacy by keeping data within the originating jurisdiction.

Key drivers for edge deployment include:

1. Latency requirements—milliseconds matter for control systems.
2. Data volume—edge filters out non‑critical data, lowering bandwidth costs.
3. Privacy regulations—data stays local, satisfying compliance.

Not every IoT use case prioritizes energy efficiency; LPWAN is ideal for battery‑constrained sensors, whereas high‑power devices may not.

Jason: Multi‑Access Edge Computing (MEC) gives enterprises local control and faster application deployment, which is crucial when handling diverse data types and volumes without relying on a distant cloud.

Samuele: Edge is the cornerstone of the Future X network—5G, cCore, and Nokia’s edge cloud—delivering unified, high‑performance connectivity.

ReadWrite: Will today’s IT landscape look drastically different in 5–10 years?

Jason: Cellular IoT has evolved from 2G voice to 4G video to 5G data. Deployments today use existing tech that will serve their lifecycle; when that lifecycle ends, devices can be upgraded to 5G. The goal is a unified access technology that supports all use cases, but achieving critical mass takes time.

ReadWrite: What should executives expect from their provider, and what key concerns should be addressed?

Samuele: Essential criteria include:

• Spectrum coverage—ensure every deployment point is reachable.
• Interference resilience—verify reliable connectivity across the site.
• Capacity—confirm sufficient bandwidth for peak demand.
• Security—guarantee end‑to‑end protection to prevent data loss or manipulation.

Contractual agreements should explicitly cover these points.

Jason: Add device management—diagnostics, firmware updates, and data extraction are vital for maintaining operational excellence.
