When AT&T moved the goalposts back again on its expected deployment of bonded VDSL2, the industry seemed to collectively shake its head in frustration. Yet another delay in the carrier’s fiber-to-the-node initiative. And yet another return to the inconvenient truths about the bandwidth limitations of copper.
“AT&T will need to do something dramatic in order to find the bandwidth to deliver multi-stream high-definition [TV], especially since the cable and satellite competition have expanded their HD channel line-ups and/or VoD libraries substantially,” said Erik Keith, an analyst at Current Analysis. “MPEG-4 will help, but FTTN DSLAMs will not be the best strategy long-term. FTTP is really the best way to go.”
However, a few developments this week are aimed at not giving up on copper so quickly.
