Background
City-scale IoT programs are often stood up per-use-case, fragmenting connectivity and data. The client wanted a shared network and platform usable across lighting, parking, waste, and environmental applications.
The problem
What made it hard.
Balancing shared-platform economics with per-application needs, and governing data access across departments and vendors.
Approach
What we built.
We designed a shared network with dedicated tenants per application, a common platform for device and user management, and application-level APIs on top. Data governance is explicit - tenants see only what policy allows, with audit trails across interactions.
Workstreams
What the program actually covered.
This was delivered as 2 coordinated workstreams over 8 months.
WS 01
Smart Street Lighting Control System
We deployed luminaire-level controllers on a mesh network with gateway backhaul to a central management system. Dimming schedules, fault detection, and energy reporting run through a single interface.
WS 02
Waste Collection Optimization System
We deployed ruggedized fill-level sensors on containers, feeding into a routing engine that produces daily plans respecting driver shifts, vehicle capacity, and priority zones. A driver mobile app provides turn-by-turn execution and completion tracking.
Outcome
What it measured.
Shared
network across applications
Multi-tenant
platform with policy controls
Faster
per-application rollouts
The client can now roll out new IoT applications in weeks rather than quarters, reusing the existing network and platform. Departmental adoption grew as the platform demonstrated reliability across pilot applications.
Our role
Network architecture; platform; governance design.

Gallery
Inside the build.
Figure 1 - Shared LoRaWAN gateways on municipal rooftops carry traffic for every application on the network, with cellular used where gateway coverage is uneconomic. Photograph is illustrative of typical gateway siting.
Figure 2 - Ultrasonic fill-level sensors fitted inside communal bins report over the same shared network; collection rounds are then planned from measured fill rather than a fixed calendar. Photograph is illustrative of the asset class instrumented.
Figure 3 - Lighting, waste and environmental departments share one platform but not one data set; tenant policy controls scope what each operator and vendor can see. Photograph is illustrative of the municipal operations setting.
