Those gigabits just ain't delivering. The glass is half full: many customers are getting downloads of 200-400 megabits. That's pretty darn good. The glass is half empty: the gigabits promised are not being achieved.
Carsten Roetz of Swisscom writes "The test customers in the village of Bibern get between 285 and 402 Mbps downstream and between 85 and 109 Mbps upstream. Results depend on copper cable length: on short copper cables (ca 24 meters) we were even able to reach 624 Mbps Downstream / 151 Mbps Upstream in field but without connected customers."
Most of the ~150 homes in the Swiss town of Bibern are within 200 meters of the city center, ideal G.fast territory. Whether 200 megabits or 500 megabits, G.fast actually getting to customers is a milestone.
