Switch off radio cells at low-load times to save energy

Network operators switch off radio cells at low load to save energy

Capacity cells and frequency bands that are hardly needed at night go to sleep, while basic coverage remains. That reduces the network’s electricity consumption without customers or emergency calls suffering.

Is this for you?

  • You operate a mobile network with capacity layers that are only needed at peak times.
  • Your network equipment supports temporarily switching off cells, carriers or antenna branches.
  • You have load data per cell and hour from network management.
First step today

Take the hourly utilisation of a cell cluster over one day, without data on individual customers, and your thresholds for switching off and back on. Use the template below to calculate possible sleep windows and check whether the coverage cell could carry them.

How to go about it

  1. Define switch-off rules and fixed limits
  2. Capture load per cell and coverage reserve
  3. Have sleep windows proposed
  4. Check windows against coverage and emergency calls
  5. Approve switch-off step by step and inform operations
  6. Evaluate savings and faults
