| wireless latency So if Flash-OFDM has 30ms latency, anybody know what Verizon's EV-DO is like? I'm using their regular NationalAccess product and latency to the first hop averages around 500ms. For the work I do, remote access to servers via command line interfaces, latency is far more important than downstream bandwidth. 500ms is sufficient, but only just. Is EV-DO better than what I have? | |

Valencia, CA | Re: wireless latency It's no different than the typical lag on a cell phone conversation. You don't typically notice it much unless you can hear the other end (i.e. call your land line, put it on speakerphone). | |

I guess you wont be using voIP over that connection. Why is latency so high?
Actually 500ms is not too bad for VoIP, pretty much like regular calls via satellite. The problem with VoIP over NationalAccess is that I only get maybe 20kbps upstream and my VoIP software doesn't have a high-complexity codec (eg g.723), so there just isn't enough bandwidth. I'm using a Mac with a bluetooth connection to a Motorola 710 which is in my back pocket. If I want to talk to somebody, I have to disconnect and use the handset like God intended.
As for why the latency is so high, I'd be interested in knowing that myself. The lag is definitely between me and the first pingable router, so it is likely to be from somewhere in the wireless delivery network. | |
