USB 2.0 extenders

I’ve been looking into USB 2.0 range extenders recently, in support of
my big-dish radio astronomy project. There’s a company called
ICRON that has a Ranger 2101 product that allows you to extend USB 2.0
up to 100M with Cat5e cable, and it’s about $300.00.
This is roughly half the cost of “traditional” extenders that used
fibre optics to extend USB 2.0 over significant distances.

So, for anyone who’d really like the USRP right next to the antenna,
something like this might be of use:

Now, I realize that the USRP2 will be using GigE, which will allow
similar distances, but there are advantages to using the
USRP1–like the dual daughtercards (we decided to go dual-polarization
on our radio telescope project, so the USRP1
fits the bill nicely).

Cheers
Marcus

BTW, when is USRP2 coming out?
Thanks.

Interesting, since I was searching on the same today :wink: I was planning
on
taking my WiFi adapter onto a parabolic dish for extending the coverage.

I read somewhere about cascading a series of (cheap) USB hubs for
getting
long distances. I’m not really sure how far that cud go. Any thoughts /
experiences ??
