Let the hive mind of Engadget get that for you.
"I've found myself using my PC for a lot of conversations lately, and I'm also considering recording a podcast to share with anyone who will listen. There are tons of USB headset / microphones out there, and I'm hoping someone has some solid recommendations based on experience. I'll consider both headsets and standalone mics, by the way, but I'd like to keep the bill under $100 if possible. Help!"
It'll be interesting to see if they can get 300mbps downstream in a car doing 55mph on an interstate highway and in a reasonable amount of spectrum.
You mean on a train?
People don't really drive in Japan as much as we do in the US, which is where I am only able to assume you are writing from, so I think that a train is a more relevant test.
But that's an interesting question nonetheless. I'm sure they'll be happy with 150 though.
Any sort of moving target is a relevant test. I just went with a typical example.
Though it requires 40mhz of spectrum to run from further research, so it's not bloody likely to happen.
