Yesterday, Sunrise Communications AG invited me to visit their #UnlimitedMobileWorkplace at the Zurich headquarter, where 1400 people work without a LAN or Wifi connection. Instead, everyone is always connected via 5G or 4G with any device, anywhere, anytime, in combination with efficient office cloudbased tools and apps from Microsoft or Google. This approach disrupts common LAN and WLAN strategies and allows a massive reduction in office network infrastructure and costs.
