Wireless USB hubs 204
HaggiZ writes "Here is alternative to the clutter of USB cables and keys sitting on your desk. Now Belkin has announced their own wire-free USB setup. It's a wireless USB hub, allowing your to plug devices into the hub and have your PC/laptop elsewhere and not need to worry about running cables along the livingroom or study to reach. Very handy for laptop users, I can imagine some very handy uses for so HTPCs as well. Shipping in spring for a shave under $130."

However, performance will drop on these items, even the fastest wireless gaming mouses have a semi-noticable lag when you use them. This lag in other items could create problems, like obfuscated code going to printers, etc.
Also, a security issue if you live in close-quarters (apartments, office buildings) because people could sniff the "packets" between the hub and device. They could watch you on your webcam, when you have your webcam software off.
Well, it will probably be good, the cons are not too bad, I will actually probably buy one myself.

Yes. The same imaginary lag that happens when I ping my laptop connected via wireless compared to a server connected by CAT5. Not to mention that many wireless mice in the past have had issues with lag. Granted, it is now very minor compared to the whole reaction cycle (percieve, process, respond = 150-200ms at best) but for really high end gaming it could be an i

There is no possible way to percieve lag since the updating is done synchronously with the USB refresh, just like it would in a wire.
If you use some bluetooth microsoft mouse or any cheaper wireless mouse, then yes, there will be VERY percievable lag. But like i said, try a mx700, mx1000, or G7. Unless your brain is helping you percieve lag because you know it is wireless...its just not th

Even if there's strong encryption, this is an issue. There are attacks that can figure out what you're typing from the timing of the keystrokes alone, and wireless USB would provide very accurate timing information to any attackers.

The very first thing I thought when I saw this article about a wireless USB hub was "Hey, now I can have a wireless Model M!" :)
Of course it isn't really wireless (would have wire going from keyboard to PS/2 => USB adaptor, then to wireless hub), but it does mean I can use a model M on the HTPC in the living room without trailing 20' of extension cable across the floor.
However, a full-sized model M has a decent amount of empty space inside it..

Point to point high bandwidth almost certainly does mean low lag. In this case even if it (ridiculously) had 100,000 byte packets (which is ridiculous), that's still only 8ms "lag", or faster than 125 frames per second.
So thanks for the bit of pragmatic wisdom, but unfortunately in this case you're being an idiot.

And you know that how? It's not just the aount of time the radio waves take. It's also the encoding and decoding. Theoretically they could have a 1 second buffer in there, giving you a second of lag. (Not that they would)
The point is, there will be extra lag introduced because of this... and none of us can say how much unless we know exactly how this thing works.

I know it by simple logic. It's a high bandwidth, short hop device, point to point technology, which alone ensures low latency. Couple that with the fact that it's intended for devices that are intolerant of latency, and that pretty much seals the case. Arguing otherwise is just inane.

This is not true, I know having designed ICs in this area that the other posters are correct in that high bandwidth is not equal to low latency. In fact this is a real design challenge in things such as wireless controllers for game consoles, where latency is everything. You are correct that many USB devices can tolerate latency (printers and such), but not keyboards and mice.

Do you even know the difference between transport speed and transport latency? It doesn't appear so from your comments. You can have a point to point fiber connection that can sustain 100gbps but that means nothing in terms of responsiveness. If it takes 10mS to establish the upstream link (which it most likely does) and then 10mS to acknowledge a packet you could have infinite bandwidth but you're still dealing with

But like the grandparent post said, the real point is that most things aren't available in Bluetooth. You want to plug in your external hard drive by Bluetooth? You can't buy one that would let you do that. Is your digital camera designed to use Bluetooth to connect to your computer? Your drawing tablet? Your PDA? Your cell phone? Your printer? Your DVD-RW drive?
Some of these things may be available in Bluetooth, but if they were and if your computer supported Bluetooth you probably would be using it already. This is a solution for things that must be USB (or you don't want to fork out to buy the Bluetooth version), and I can see it being quite handy. It would be nice to have a little collection of USB stuff that I could plug into my laptop with one little adapter so I'm still cordless instead of the wire running over to the hub. And with a HTPC (as someone else mentioned) you could use this to plug USB stuff in by the couch where you are (game pads, memory sticks, etc) instead of having to reach behind your collection of AV equiptment where the PC is.
