Cities: on the ground
Cities
The street, measured block by block.
Air quality, noise, traffic, urban heat and street flooding, with open data as a procurement credential.
City block
City block
City blocks with sensors and small cells on the street furniture.
City block
Small cell on a street pole
A small cell on a street pole adds capacity and hosts the block’s sensors. Street-level capacity at 8 m on existing poles; each also hosts sensors.
City block
City block
The edge node publishes open data; personal data never leaves the block. Aggregates counts below a privacy threshold and publishes open city data.
City block
Air-quality node
Air-quality nodes are corrected against a reference station. Low-cost PM and NO₂ sensors corrected against a reference station, with the correction published.
Proof
What buyers ask to see.
- Co-location calibration reports against reference monitors
- Data-completeness service levels
- An open-data API
- A privacy impact assessment for video and probe sensing
- Accessible dashboards
01How it works
A station joins, then the work is shared.
One station runs the protocol from first contact to publishing; the graph beside it shows how this sector’s use cases share kit and products.
02Deployment scenarios
How the grid is deployed here.
From the sector research, each with the observatory template that serves it where one exists.
Protocol & Grid, Sensors & instrumentsHybrid air-quality network
Reference analysers plus calibrated low-cost nodes; low-cost sensors alone do not meet regulatory requirements.Hardware & power, ConnectivityMunicipal low-power radio or private 5G layer
A city-wide connectivity layer as digital public infrastructure.03Proof
What buyers ask to see.
The evidence a procurement in this sector asks for, from the sector research. Each item is produced by the grid as a record, not written up afterwards.
- Co-location calibration reports against reference monitors
- Data-completeness service levels
- An open-data API
- A privacy impact assessment for video and probe sensing
- Accessible dashboards
04Participation
