Planned Obsolescence in Lifts
This week I learned that mobile phones use mobile telephony for the emergency call system. This surprises me because I would expect them to use a fixed line rather than a mobile phone signal but also because when Swisscom or another telecom provider stop broadcasting on a frequency range like 3g, then all devices need to be updated to a newer standard. This means that all lifts need to be equipped with new mobile telephony devices.
