NEC's new WUSB controller supports up to 32 devices at speeds up to 480Mbps.

We are sure to hear more about Wireless USB at CES and IDF this year as peripherals ranging from printers to digital cameras to music players are sure to embrace the standard. NEC's new uPD720170 host controller can support up to 32 devices simultaneously at speeds ranging from 53.3 to 480 Mbps at a distance of up to 3 meters. The controller is compatible with the WiMedia MAC, WiMedia MAC-PHY and Wireless Host Controller Interface (WHCI) specifications.  Samples of the chip are now available with production ready chips set to ship in the second quarter.

What are the improvements of wi-usb over bluetooth?
I can see speed, but beyond that?

It will be popular just because it's USB, and if it manages to get built onto motherboards it will be unstopable. I can see it being nice for things like printers, scanners, camcorders, cameras.

Bluetooth has also been proven insecure. God knows what encryption they will use, but I hope it's been subjected to an open review.

Bluetooth just never seemed to catch on...


BlueTooth security

I am of the impression that BT is quite secure as it uses frequency hopping and encryption.
This link http://www.niksula.cs.hut.fi/~jiitv/bluesec.html#chap7 concludes that BT is secure enough for non-sensitive data (and it can be quite secure if the PIN codes are sufficiently long). Of course it is possible for dedicated hackers to listen to e.g. keystrokes from a usb keyboard, but the need for the hacker to be quite close to the transmitter presents a problem to the hacker. Furthermore, for a hacker to put recorded keystrockes to use, he normally needs some kind of digital signature which has to be obtained before the users back account can be emptied. Therefore, if you think about the workload/reward, it would probably make much more sense for a hacker to go home in his comfy chair and either intercept some credit card numbers from the web or hack the users computer to install a keystrocke logger and obtain the signature used for web banking.

...Also the security issues (AFAIK) is caused by issues in the specific implementation in devices and not by issues in the protocol itself.


How much?

I wonder how much this will cost.

And if it's hackable... that might be scary... then again no more scary than the other stuff.




range

A faster alternative to BT would be welcome, although does anyone else find a range of 3m slightly underwhelming? Such a maximum at the higher end of the speed range I can understand, but still. And if this is 'clear path' distance, I assume it'll come down in practice if desks, walls etc are in the way.
