A wireless USB is basically a short range radio communication device which has a very high bandwidth. The wireless USB is also called as WUSB mainly to differentiate it from its competitors. Wireless USB has a capacity of sending 480Mbit/s at a distance of around 3M. Now a day’s wireless USB is used in the following devices:
1. Game controllers.
2. Printers.
3. Scanners
4. Digital cameras
5. MP3 players
6. Hard disk
7. Flash drive
A wireless USB allows connecting 127 devices directly to the host since there are no wires or ports needed so there is no longer need of hubs. The capability of a WUSB can be added in a system with the help of a host wire adapter. The host wire adapter is basically a USB device that can be attached externally to a laptop or with a desktop or internally with a laptops mini card interface.
The important function of WUSB is that it supports dual-role-devices which in addition perform as a host. A common confusion these days is between WUSB and UWB. There are no major drivers for WUSB other than the Microsoft windows so this is a basic flaw in this device. WUSB is basically defined as a bus which can connect a host with a number of peripherals. The basic function that the host performs is that it divides the bandwidth through a strategy known as time division multiple accesses. The hosts can communicate with the devices up to 10 meters.
A typical USB model consists of mainly these layers but few adjustments have been made in it recently:
1. The function layer
2. The device layer
3. The bus layer
AUSB supports the following data rates:
• Low speed
• Full speed
• High speed
• Super speed
A USB connecter has the following properties:
• Usability
• Durability
• Compatibility
