wireless USB vs wired USB-difference between wireless USB and wired USB

Following are the benefits of wireless USB over wired one.
• Wireless USB delivers speed equivalent to wired USB connection.
• It delivers maximum power efficient system.
• Using built in protocols and authentication procedure, it provides secure data communication.
• It is backward compatible with applications developed for wired USB.
• It delivers plug and play capabilities similar to wired USB.

Wired USB can be converted to wireless USB with the use of wireless adapters. Various Wireless adapters are available such as wifi adapters, bluetooth adapters, IrDA adapters, zigbee USB adapters and so on. Each of these adapters support different wireless standards. This adapters can be easily plug-in into USB port of the devices.
