Seven years after the pilot, 27.7% of connections had a smart meter: 98.4% in Gangseo, 6.3% in Yeongdo. A city councillor had already challenged the cheap radio standard the utility picked at the start.

Busan's Water Authority has been replacing analogue water meters with IoT smart meters since a 2018 pilot, running them over the city's own LoRa network alongside commercial NB-IoT. Meters report up to 24 times a day, sending consumption plus temperature, over-flow and backflow flags so leaks and abnormal flow surface between billing reads. Progress is slow and uneven: the authority's own December 2025 tally shows 101,053 of 365,229 connections converted, 27.7%, ranging from 98.4% in Gangseo to 6.3% in Yeongdo. A city councillor challenged the LoRa choice in 2023, citing weak reception and 12.6 billion won paid to one supplier.

📊 Impact

The authority's own status page reported 101,053 of 365,229 water connections on remote meters by December 2025 (27.7%), seven years after the pilot, with office-area coverage ranging from 98.4% in Gangseo to 6.3% in Yeongdo.

🎓 Lesson

A cheap radio standard picked at pilot stage can outlive its credibility: Busan was still funding LoRa terminal maintenance years after peer cities moved to NB-IoT.

The radio is the cheapest rung. Who owns it, and what did it end up carrying?

A LoRaWAN network is coverage in a year for the price of a few dozen gateways, which is why so many cities have one. The interesting questions come afterwards: whose asset it is, and what it actually carries once the pilots are over.

The radio is the cheapest rung. Who owns it, and what did it end up carrying? — side-by-side comparison of 4 atlas entries; the "Cost" column honestly shows "not public" where no figure was ever published.
