What is wireless USB
This page covers wireless USB basics and benefits.It compares wireless USB vs wired USB and mentions difference between wireless USB and wired USB.
The large number of USB interfaces are in use throughout the world. This is because users are adopted to use of digital devices such as laptops, PCS, portable hard drives, flash drives, cameras, DVD players, MP3 players and other mobile devices.
Unlike wired USB counterpart, wireless USB does not require any cables and works on radio frequency waves. It follows the standards set by USB-IF (USB Implementers' Forum, Inc.). It works on UWB standard. It provides speed of 110 Mbps to 480 Mbps with distances of 3 meters to 10 meters respectively.
USB-IF has more than 100 companies contributing for the success of USB based products. The companies include Samsung, NEC, LSI, HP, Microsoft etc.
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.
