Multi-function smart poles — folding streetlights, cameras and sensors into one post

Since April 2020, Chengdu City Investment Smart City Technology Co. (a subsidiary of the state-owned Chengdu City Investment Group, founded October 2019) has been replacing standalone streetlight poles, traffic-camera masts, signage and signal poles with combined 'smart multifunction poles' carrying LED lighting, 5G small cells, traffic and environmental sensors, emergency call points, phone/EV charging and (as of a 2026 rollout) roadside charging piles. Over 3,500 poles were in place along corridors like Chengdu's First Ring Road, Phoenix Mountain Sports Park and East Suburb Memory, with a stated plan to reach 30,000+ poles across the city within 3-5 years for roughly ¥1.5 billion. In its managed area the company reports a 99.38% monthly streetlight-uptime rate and about 40% energy savings from LED retrofits versus the old sodium lamps — but for most of the 30,000-pole target, the poles installed so far mainly just replace old streetlights; the sensor and camera functions are described as 'reserved for future use' rather than fully active.

📊 Impact

3,500+ multifunction poles installed against a 30,000-pole, ¥1.5 billion, 3-5 year target; 99.38% monthly streetlight-activation rate and ~40% energy savings vs. sodium lamps in the company's managed area (operator-reported).

🎓 Lesson

A 'multifunction' pole is often a streetlight first and a sensor platform later — Chengdu's own operator admits most of the smart hardware capacity is 'reserved,' not yet switched on.
