What this page is: The central index for the WiFi Module Case Studies series — a directory of 17 documented deployments (5 solution hubs + 11 individual blog case studies) across five verticals: Enterprise & Commercial, Industrial & Automation, Smart City & Infrastructure, Smart Home & Consumer IoT, and Upgrade & Optimization. Each entry states the module class used, the core engineering challenge, and a measurable outcome.
Who it is for: Embedded hardware engineers, product managers, and IoT solution architects who need to find a precedent deployment matching their own application before committing to a module, a form factor, or a host interface.
How to use it: If you already know your project type, jump straight to the selection path table — it maps eight common project types (Enterprise AP, AGV/AMR, medical device, smart city edge gateway, battery IoT, PLC retrofit, retail POS, smart camera) to the single most relevant case study. If you are still scoping, browse the vertical sections below.
What makes this different from a datasheet roundup: every entry is tied to a real deployment constraint — temperature range, handoff latency, battery life, or compliance requirement — rather than a headline specification. Cross-cutting precedents (for example, a module used in both a medical and an industrial deployment) are noted so the same part can be reused across verticals.
Enterprise and commercial wireless projects have a different risk profile from consumer devices — the network must support many users, protect business data, and keep critical endpoints online during busy operating hours. These cases cover AP auxiliary connectivity, high-density meeting rooms, retail POS, medical device upgrades, and hotel room control systems.

Smart city deployments differ from indoor networks because endpoints are spread across public space, powered intermittently, and expected to survive years of weather without service visits. These cases cover edge gateways, underground parking sensors, and outdoor surveillance cameras — each balancing reach and battery life against cost.

Result: sustained 4K video upload with night-mode reliability and outdoor weather resistance.
Consumer IoT wireless design is dominated by cost, power, and coexistence rather than raw throughput. These cases cover voice control, smart locks, and home automation hubs where battery life and BLE coexistence usually decide the module choice.
Series overview for smart home applications covering smart locks, voice control, and home automation hubs.

Upgrade projects start from an existing deployment and ask a different question: how much performance can be recovered without re-spinning the hardware. These cases cover migration from WiFi 5 to WiFi 6/6E/7 with throughput benchmarking and cost-benefit analysis.

A: The five solution hubs (Enterprise, Industrial, Smart City, Smart Home, Upgrade) are vertical landing pages that group related scenarios and an evaluation framework. The individual blog case studies go deeper into a single technical challenge, the module selection rationale, and measured results. Start with a hub to scope your vertical, then use a blog case study for the specific problem.
A: The case studies cover MiniPCIe, M.2 (Key E and B/M), and solder-down module classes, spanning WiFi 5 (802.11ac) through WiFi 6/6E. Several industrial and upgrade cases also include 5G/LTE and BLE coexistence. Form factor selection within a case study follows the same host-slot, thermal, vibration, power, range, and lifecycle constraints used across the series.
