Ultra Wideband Hub Coming in October

Posted by ryuzaki0 on from the let-me-give-you-a-big-hub dept.

Dhiram writes "Japan based Y-E Data Inc. has announced the development of the "Wireless Hub" based on UWB (ultra wideband) wireless technology. It is the first UWB commercial application announced. The Wireless Hub mounts a UWB wireless communication module, as well as four USB ports. It comes with a USB dongle with UWB connectivity which connects to the PC. Other USB peripherals can be connected to the wireless hub, which then connects to the PC through UWB and has an effective data rate of 100 mbps over a 10-m distance without obstacles."

  1. Power? by Apocalypse111 · · Score: 2, Interesting

    So does this thing run on batteries or wall power? I mean, would I be able to, say, charge an iPod off of it? If I were to plug in my favorite wired Logitech mouse, would I still have to deal with the annoyance of replacing batteries for the convenience of being able to controlling my PC from the couch?

    I'd have to imagine that this thing, due at least to its own wireless power demands, would have to get wall power, but then is it truely "wireless"? Even with this kind of limitation, I can easily see uses for such a device, however.

    There is no mod option "-1: Disagree" for a reason. "Overrated" is not an acceptable substitute. Post something instead.
  2. good for cameras? by TheGratefulNet · · Score: 4, Interesting

    I've been waiting for a while now (!) for wireless usb (there are 2 standards, from what I understand) to come out.

    I'd like to be able to shoot 'tethered' and not have the camera or the pc know or care that its a wireless link.

    not having cords tangle while shooting would be a big bonus; plus I could just upload all my pics to my pc and not care about storage card limits (assuming there IS supported wire-based tethered shooting for your cam; many do not have it).

  3. Re:Antenna issues by Moby+Cock · · Score: 2, Interesting

    I think you hit the nail on the head. The antennas for UWB are very hard to get right. Initially, designers were focused return loss but have recently discovered that the gain is as important. The s11 is just not sufficient to characterise UWB antennas. The reason is that the antennas have different gains along the operation band of the antenna. This is effectively inserting a transfer function to the channel. The s21 curves and time-domain analysis are now being more carefully considered. This has a bandwidth of ~500 MHz and is strictly a UWB device, but given some time to sort out the antennas I think we will see devices with nanosecond pulses and/or ~4 GHz bandwidths. Truly amazing data throughput potential. Think Blu-Ray player to HDTV wirelessly.

    one word: cameras.

    its not about distance. its about being tangle free. the tripod and other danglies are bad enough as it is..
