The document discusses the Wi-Gig specification for wireless networking. It describes Wi-Gig's ability to transmit data at rates up to 7Gbps using beamforming and its structure, which includes physical, medium access control, and protocol adaptation layers. Wi-Gig aims to drive development of interoperable wireless products and overcome limitations of current standards like Wi-Fi. It could enable single-wireless transfers of files, displays, and streaming media.

4. Introduction
 Current commercial standards (Wi-Fi,
Wi-Max etc).
 Wireless Gigabit Alliance (Wi-Gig).
 Designed to drive a global ecosystem
of interoperable products.

5. Wi-Gig Specification
 Data transmission rate upto 7Gbps.
 Supports low-power handheld devices.
 Support for Beamforming.
 Widely used advanced security and
power management for WiGig devices.

6. Structure of Wi-Gig
Physical Layer(PHY)
 Enables low power and high
performance WiGig devices.
Medium Access Control (MAC) Layer
 Supports Advanced usage models.
Protocol Adaption Layers(PALs)
 Allows wireless implementations.

7. Physical Layer (PHY)
 WiGig specification defines four
channels, each 2.16 GHz wide.
 These wide channels support
applications such as uncompressed
video transmission.
 Supports 2types of modulation &
coding schemes.

8. Medium Access
Control(MAC)layer
 Network Architecture, Power Management,
Advanced Security.

9. Protocol Adaptation Layer

10. Requirements
 Plasma Silicon Antenna used.
 Wi-Gig Beamforming

11. Usage Models

12. Conclusion
 A single tech. for instant file transfers,
wireless display & streaming HD
media will be available in the market in
the coming years.
 Hopefully we will be seeing the indoor
barriers being overcome by Wi-Gig in
the coming years.
