Each of the four ports on the hub supports both USB1.1 and USB2.0 specifications and their recommended speeds. It's unknown whether this hub runs on the Ultra-Wideband (UWB) spectrum which ensures the wireless signal does not interfere with other wireless networks such as your home network or cordless phones.
D-Link's DUB-2240 is another wireless hub that is less attractive, similarly priced and runs on UWB.
