The most expensive IoT architecture decisions are the ones made before a single device ships. Coverage strategy, SIM technology, network resilience and connectivity model all get locked in early, and each one tends to surface later as a coverage gap, an avoidable site visit, a surprise invoice, or a lock-in clause that constrains the deployment for years.
This playbook gives technical and operational teams a structured way to make those calls on evidence rather than vendor marketing. It works through four phases, from defining requirements to selecting technology, evaluating vendors and validating through a pilot, with the frameworks, matrices and checklists to work each phase properly.
What’s inside
- The four-phase architecture framework, from requirements definition through to deployment and scale
- How to choose between LTE-M and NB-IoT, with a decision tree covering mobility, latency, data volume, voice and deep-indoor coverage
- Where eSIM earns its place over traditional SIM, and how the value compounds the longer a device stays in the field
- When single-network connectivity is enough, and when mission-critical uptime calls for multi-network resilience
- Roaming, local and hybrid connectivity models compared, with guidance on which suits which deployment scale and geography
- A vendor evaluation toolkit: RAG scorecard, weighted decision matrix, full RFP checklist, and the red flags that should stop an evaluation in its tracks
- A pilot validation framework that tests coverage, battery life, cost and security against defined success criteria before you commit to scale
- A 10-year total cost of ownership model for comparing traditional SIM and eSIM like-for-like
- Pre-deployment, deployment-day and 30-day checklists to take a validated design into production
Whether you are planning a new deployment or improving an architecture already in the field, the frameworks in this playbook are built to reduce risk and improve long-term outcomes. Download the free PDF to work through your own connectivity design.
