Sunrise has launched its second 5G network in Switzerland, connecting the LAAX resort on the Crap Sogn Gion mountain.
The operator gave a variety of futuristic, and far from market, use cases powered by the network, from holographic ski lessons, 360 degree live broadcasts of sporting events, guests being served dinner by humanoid robots and booking activities via blockchain.
A forthcoming Internet of Things network will help skiers find objects they lost on the slopes.
Sunrise deployed a 3.5GHz network using 8x8MIMO and offering speeds of more than 300MBps. It said it expects to deliver speeds of more than 1GBps when 32x32 and 64x64 antennas are available.
Sunrise CEO Olaf Swantee said: "A world record under laboratory conditions, the first end-to-end 5G network in Switzerland with '5G for People', and now the world's first standardized 5G network at a ski resort.
"All of this has been achieved in just under 12 months. Holding on firmly to its title of 5G pioneer, Sunrise is continuing to forge ahead with its '5G for People' initiative.
"We're proud of the fact that we're now able to go live with the world's first 'fiber optics over air' network at Switzerland's most innovative ski resort."
