A method finds energy-wasting sites by comparing them to similar ones, without needing prior labels.

Mobile phone towers and equipment sites use huge amounts of electricity. Many sites waste power because of broken cooling controls, idle radios, or extra hardware draining energy. Operators struggle to spot these faults because they do not have lists of known broken sites to train computers on, and old energy records already include wasted power. Researchers created a new system to solve this. Their idea is that sites with similar setups and workloads should burn similar amounts of energy. The system maps all the sites into a shared visual space. Sites that match stay close together, but if one site consumes way more power than its peers, the system pushes it away. Finding these pushed-out sites creates scores that show operators which locations engineers should inspect first to save energy.

Why it matters

Mobile network operators spend heavily on energy, but hidden inefficiencies like faulty cooling often go unnoticed. This approach helps them pinpoint sites where energy savings are likely, so engineers can focus their efforts where it counts.
