Items in the Crutchfield catalog for a long time, but I stupidly did not notice until today:

OmniFi DMS1

OmniFi MP1

Discuss.

Looks interesting. I'm sure it won't work as smooth as they make it out to be. Transfering MP3s over 802.11b is slow as hell... not to mention the receiving device being in the garage (or in the driveway).

I'd love to see it in action though.

Gee, that system diagram looks eerily familiar. I wonder if there are any other products that'll work like that?

good concept, but transferring over 802.11b is DAMN slow, 802.11a or g would be better.

802.11a wouldn't make it through the walls of your house and/or car and G is really flakey right now.

I routinely transfer over 802.11b, as long as you're not trying to upload your collection instead of an album it's tolerable.

In my experience, 10baseT is 2-3 times faster than 802.11b. Moving more than a couple albums at a time is horribly slow.

802.11a on the other hand is wicked fast.

802.11g is fast... when it works.

You know, it's funny how we're supposed to judge transfer speed based on the "MBPS" rating of the equipment, and it never seems to really go by that number.

10baseT=10mbps/sec
802.11b=11mbps/sec
USB=12mbps/sec

But actual data throughput ends up being exactly the opposite order...

These appear to be launching this week (according to Crutchfield and other press releases).

All of the wireless LAN technologies quote the signalling rate. The maximum actual throughput is half the quoted rate.

So with 802.11b you're looking to get about 4-5mbps and 802.11a/g is around 25. Some manufacturers implement their own systems and double the standard rates.

Overhead is greatest on 802.11b then USB and finally Ethernet has the lowest. You'll never get the full bandwidth because the protocol being used sucks up some of it.
