n78 3.5 GHz: 3.30–3.80 GHz · λ 84.4 mm · Main 5G capacity layer, massive MIMO · 3GPP TS 38.101-1

Field environments

City block

Small cells on street poles, air-quality nodes and heat sensors across four blocks, joined to an edge node that publishes open city data.

Network scenes here: Radio access in a city centre · IoT in the city: a street-light mesh and LoRaWAN

In this scene

Small cell on a street pole

Street-level capacity at 8 m on existing poles; each also hosts sensors. (3GPP TS 38.104 (local area), O-RAN 7.2x)

Air-quality node

Low-cost PM and NO₂ sensors corrected against a reference station, with the correction published. (EN 17660-1, US EPA PM sensor targets)

Compute racks

Aggregates counts below a privacy threshold and publishes open city data. (OGC SensorThings API, ISO 37120)

Tour transcript

1. City blocks with sensors and small cells on the street furniture.
2. A small cell on a street pole adds capacity and hosts the block’s sensors.
3. Air-quality nodes are corrected against a reference station.
4. The edge node publishes open data; personal data never leaves the block.

How the numbers are computed

Signal and interference follow the urban micro-cell street-canyon model of 3GPP TR 38.901 at the band chosen on the strip, with the buildings of the drawing as obstacles; the capacity bound is Shannon’s at the median.
