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.<\/p>\n<p>If I had the power to change things I would leapfrog from 3g to 5g and I would see whether this system could be forward compatible with car charging for when cars are switched from petrol to electric. There is a chance to address two needs at once.<\/p>\n<p>It&#8217;s a shame that we can&#8217;t just re-use an old phone as a modem interface between the lift and the 4g\/5g network and that we can&#8217;t use wifi or some similar technology. To the best of my knowledge WiFi is backwards compatible.<\/p>\n<h2>And Finally<\/h2>\n<p>We see how rarely I use lifts, that I never noticed the lack of a mobile phone signal. I always run up and down the stairs if and when I have the chance. I will often explore and look for stairs, when I am not familiar with a building. The most recent example is when I parked at the airport beneath L&#8217;Ar\u00e9na. I used the stairs.<\/p>\n<p>The only time I use lifts is when I have camera gear or shopping. The rest of the time I run up and down stairs. This is a habit from spending most of my life living in places with several floors, including school, work and more. It&#8217;s just habit.<\/p>\n","protected":false},"excerpt":{"rendered":"<p><span class=\"span-reading-time rt-reading-time\" style=\"display: block;\"><span class=\"rt-label rt-prefix\">Reading Time: <\/span> <span class=\"rt-time\"> &lt; 1<\/span> <span class=\"rt-label rt-postfix\">minute<\/span><\/span>This week I learned that mobile phones use mobile telephony for the emergency call system.
