Five years ago this week… G.fast chip leader Sckipio was fighting it out with Broadcom in the run up to Broadband World Forum 2016 in London. In partnership with Calix, Sckipio had implemented Dynamic Time Assignment (DTA), allowing bi-directional allocation of bandwidth in twisted pairs, while its new 212 MHz variant of G.fast was double the previous speed. But Broadcom was quick to kick back just days later with a second generation BCM65400 chip offering equivalent speeds and the suspiciously similarly named feature of dynamic time allocation. While Sckipio looked to be the main force driving change in the telco broadband market, Broadcom was close to matching it stride for stride.
