In addition to the previous answer:
Swisscom tested various mesh systems available on the market and was not really convinced by any of them.
They then developed the WLAN box. Based on my own experience, it works really well and is perfectly integrated into the system. And the price is sensationally cheap.
The only “disadvantage”: only works with the Swisscom Interbetboxes.
But if you change provider, the parts can be sold very well on Ricardo/Tutti
