At one point a couple of decades ago, even sophisticated access technologists might privately have thought standard twisted-pair cables used by telcos would not work reliably enough to deliver 10 Mbps to scores of megabits per second.
By the same token, many would not then have believed cable TV hybrid fiber coax networks capable of reaching hundreds of megabits per second, much less gigabit speeds. But credit hard work, technical cleverness and Moore’s Law for breaking all those limits.
Swisscom is deploying G.fast, which allows Swisscom to reach transmission speeds of up to 500 Mbps on networks with relatively short copper drop cables and optical fiber distribution networks.
That deployment is part of a process whereby legacy networks are upgraded to deliver bandwidth that once was thought “impossible” on telco legacy copper drops, cable TV hybrid fiber coax, fixed wireless or mobile networks
Better radios, signal processing and advanced modulation techniques, plus new architectures, are also are contributing to the way mobile and fixed wireless networks is improving
In the medium to long term, Swisscom intends to supply 85 percent of all Swiss households and businesses with bandwidth of at least 100 Mbps by the end of 2020.
