IoT Knowledge Hub
The most important IoT terms, clearly explained.
The IoT terms that help you make smarter decisions.
IoT comes with its own language.
From LTE-M and eUICC to APNs, gateways and OTA updates – the terminology can quickly become technical, fragmented or unnecessarily complex.
That is why we created the Knowledge Hub: one place where the most important IoT terms are explained clearly, practically and in plain English. So you can understand the language behind connected products, ask better questions and make stronger decisions with more confidence.
Better understanding leads to better IoT choices.
In IoT, complexity often does not start with technology alone. It starts with unclear terminology.
A word gets used loosely.
A concept gets misunderstood.
A network choice sounds interchangeable when it is not.
And decisions are made before the real implications are fully understood. That is exactly why a Knowledge Hub matters.
We believe technical language should not create distance. It should create clarity.
One place for the language behind connected products.
The Knowledge Hub brings together the most important terms used across IoT connectivity, SIM technology, network configuration, portals, security, hardware, data flows and standards.
Each term is explained in a practical way:
- what it means
- why it matters
- when it becomes relevant in practice
That means this is not just a glossary.
It is a working guide to the concepts that influence how connected products perform in the real world.
The right terms, grouped in the right way.
To keep things easy to navigate, we organise the Knowledge Hub into the key areas that matter most in IoT:
Connectivity & Networks
Understand the basics of mobile networks and what they mean for reliability, coverage and performance – from 2G, 4G and 5G to LTE-M, NB-IoT, latency, throughput and roaming.
SIM, eUICC & Provisioning
Learn the language behind SIMs, eUICC, remote provisioning, ICCID, IMSI and lifecycle management – and understand what really matters when devices need to stay flexible over time.
Network Configuration & Routing
Get clarity on APNs, private APNs, static IPs, NAT, VPNs, DNS and firewall rules – the building blocks behind secure and predictable connectivity.
Management, Portals & Operations
Explore the terms that shape day-to-day control: connectivity platforms, device management, fleet management, monitoring, alerts, policies and lifecycle management.
Security
Understand the concepts that support secure IoT foundations, from device identity and PKI to mTLS, secure boot, firmware signing, OTA updates and Zero Trust.
Radio, Signal & Performance
Learn how signal quality and device behaviour affect performance in the field, with terms such as RSSI, RSRP, RSRQ, SINR, antenna gain, PSM and eDRX.
Hardware & Edge
Understand the role of modules, sensors, trackers, gateways, routers and edge computing in the wider IoT chain.
Data, Protocols & Integrations
Get familiar with MQTT, HTTP(S), REST APIs, webhooks, payloads, time-series data and event-driven architectures.
Standards, Regulation & Governance
See how terms such as GSMA, CE, RED, ISO 27001, NIS2, data residency and audit trails influence trust, compliance and scalability.
Operations & Troubleshooting
Explore the practical language behind pilots, rollouts, uptime, KPIs, truck rolls, RMA and root cause analysis.
A few of the terms teams look up most often.
eUICC
A SIM technology that allows operator profiles to be downloaded and changed remotely.
It matters because it gives IoT deployments more flexibility without requiring physical SIM swaps in the field.
LTE-M
A 4G-based network technology designed for IoT, with lower power use and stronger indoor reach than traditional LTE.
It matters because it often offers a strong balance between battery life, mobility and coverage.
NB-IoT
A narrowband IoT network technology designed for deep indoor coverage and very low power usage.
It matters because it works especially well for fixed sensors that send small amounts of data infrequently.
APN
The access point that determines how a device sends data into the mobile network.
It matters because the wrong APN can lead to no connectivity, poor routing or an insecure setup.
OTA Updates
Over-the-air updates that allow firmware or software to be changed remotely.
They matter because long-life IoT deployments need a practical way to fix vulnerabilities and improve device behaviour over time.
Gateway
A device that connects local equipment or sensors to the internet or a wider IoT environment.
It matters because it reduces complexity and helps bring data from the field into usable digital workflows.
Because IoT language should help you move faster, not slow you down.
When teams share the same understanding of the core terms, decisions become easier.
Conversations become sharper. Risks become more visible. And choices about connectivity, security, hardware and rollout become more deliberate.
That is the real role of this page.
Not to overwhelm people with jargon, but to give them a more confident starting point for building, improving or scaling connected solutions.
Our Knowledge Hub is ideal for:
1
Teams new to IoT
You want to understand the basics clearly, without getting buried in technical language.
2
Businesses building or scaling connected products
You need a shared understanding of the concepts that shape product, rollout and operational decisions.
3
Commercial and operational teams
You want to explain IoT more clearly internally and externally, without oversimplifying what matters.
