Verizon has finally awakened to one of the major weak points in cable broadband services delivered and taken steps to exploit it. A FiOS ad talks about the fact that FiOS delivers not only fast downloads, it delivers uploads 25 times faster than cable, and upload speed was the big problem with cable from day one. Cable broadband is shared bandwidth in both directions, but the statistical sharing of the downlink still lets customers have decent experiences given that there’s as much as 8 or even 16 Mbps to share. But the uplink is only between 256 kbps and 512 kbps, and any significant uploading (such as P2P hosting) creates a major problem for the MSOs. That’s why Comcast is prepared to duke it out with the FCC on the issue of P2P traffic management, and that battle is likely what’s spurring Verizon to take the offensive in its ads.
