  1. INTRODUCTION UNIVERSAL SERIALBUS(USB) Universal Serial Bus (USB) is a specification to establish communication between devices and a host controller (usually personal computers), developed and invented by Ajay Bhatt while working for Intel. USB can connect computer peripherals such as mouse, keyboards, digital cameras, printers, personal media players, external hard drives.

  INTRODUCTION…………………..CONTINUE WIRELESS UNIVERSAL SERIALBUS(WUSB) Wireless USB mean USB without wires. In short “wireless usb is also a specification to establish communication between devices and a host controller (usually personal computers) but without wires, by the use of ultra wide band”.

  2. WHY WIRELESSUSB Comparison with wired USB 1. High performance speed 2. No hassle of wire 3. Portable Comparison with BLUETOOTH 1. low performance speed at higher distance 2. more secure Comparison with WI-FI 1. cost effective. 2. wire USB signal are more secure than Wi-Fi signals as WI-FI signal are adversely effect by natural disaster such as thunder storm.

  3. ULTRA WIDEBAND IN WUSB Ultra-wideband (UWB, ultra-wide band, ultra band, etc.) is a radio technology that can be used at very low energy levels for short- range high-bandwidth communications within the frequency range of 3.1 GHz to 10.6 GHz by using a large portion of the radio spectrum. UWB CHARACTERISTICS •Very high bandwidth within shorter range(110 Mbps within 10 m). •Low cost •Passing through building blocks, walls etc

  ULTRA WIDE BANDIN WUSB….CONTINUE UWB APPLICATION Due to the extremely low emission levels UWB systems tend to be short-range and indoors applications. High data rate UWB can enable wireless monitors, the efficient transfer of data from digital camcorders, wireless printing of digital pictures from a camera without the need for an intervening personal computer, and the transfer of files among cell phone handsets and other handheld devices like personal digital audio and video player.

  4. TOPOLOGY REQUIREDIN WUSB The Wireless USB Host Can Logically Connect To A Maximum Of 127 Wireless USB Devices. The Host Initiates All The Data Traffic Among The Devices Connected To It, Allotting Data Bandwidth To Each Device Connected. With The Use Of Hub We Can Connect The Devices.

  5. HOW WUSBWORK The fundamental element of the Wireless USB protocol is the Micro-scheduled Management Command MMCs are used to help devices discover information about a Wireless USB. In wired USB, data transmissions were executed using IN and OUT token packets. Named with respect to the host, an IN is used by the host to read data from a device while an OUT writes data from the host to a device. So, a Wireless USB DT CTA is the equivalent of a USB token IN; a Wireless USB DR CTA is the equivalent of a USB token OUT.

  6. WIRELESS USBINSTALLATION The installation of wireless USB is very simple. install the driver of particular USB device in the host USB and than connect the dongle in the host USB port. we don’t have to install the driver again and again. when the first time we want to connect the wireless USB to our pc or any other device than we have to install the driver only once.

  7. WIRELESS USBSECURITY For security two steps are being performed 1.Data association 2. Encryption 1. Data association 1. Devices associate wirelessly 2. User must enter a hex code manually. SESSION KEY A session key is an encryption and decryption key that is randomly generated to ensure the security of a communications session between a user and another computer or between two computers. Throughout each session, the key is transmitted along with each message .

  WIRELESS USB SECURITY…..CONTINUE 2. Encryption During each session devices derive a session key. Wireless data is encrypted using session key.

  10. WUSB ADVANTAGES 1. High performance At launch, Wireless USB will provide speeds up to 480 Mbps 2. Give a good wireless range 3. Wireless usb is portable 4. Simple in installation.
• 17.
  11. WUSB DISADVANTAGES 1. The wireless keyboard and mouse use a USB port and do not give you anything else. The Bluetooth adapter uses the same port, but also lets you connect Bluetooth stereo headphones, your mobile phone, etc. 2. The range of wireless USB technology comparison to WI-FI is low. 3. External power source or battery required. 4. Cost is higher than wired USB.

  14. WUSB FUTURE Intel and fellow travelers will continue to drive the Wireless USB initiative into the marketplace as the first USB initiative into the marketplace as the first commercial application to run on top of the common UWB radio platform. GEFEN HMDI EXTENDER – Coming soon… – Based on UWB. – Retail price of $699.00 – Range of 20 meters; data rates up to 480 Mbps – Frequency band: 3.1 - 4.8 GHz
