Modern networks
A comprehensive efficiency programme at Swisscom ensures that efficiency measures are realised in the networks. Through new architectures, the use of improved technologies, more energy-efficient processes (e.g. fresh air cooling for base stations in the mobile network) and the dismantling of obsolete network elements (e.g. TDM platform), Swisscom saved 40.3 GWh in the fixed broadband network and mobile network in 2019.
