## Tour transcript

1. Small-cell poles at the junctions, air-quality nodes on the footways and an edge node in the exchange, among blocks drawn to their heights.
2. Street-level capacity on a pole that also carries an air-quality node.
3. Particulate and gas sensors corrected against a reference station.

## In this scene

**Small-cell pole**: Street-level capacity on a pole that also carries an air-quality node. (3GPP TS 38.104 (local area BS))
**Air-quality node**: Particulate and gas sensors corrected against a reference station. (EN 17660-1)
