BT has been touting its success at implementing sleep cell technology at 4G sites on the EE mobile network. Energy consumption reduction is welcome, but the savings here are meagre, and meaningful change will be felt more in a 5G Standalone network. However, with new 5G equipment also comes the looming specter of Scope 3 emissions. BT is using energy-saving ‘cell sleep’ technology at 19,500 4G sites on EE’s network. This puts certain carrier signalss to sleep when capacity is not needed, using machine learning to predict quiet periods of demand. The system automatically wakes up during busy periods and is configured to react to unexpected surges which might occur during scheduled sleep modes. The sleep modes are predominantly running…
