IntroductionCurrent commercial standards

(Wi-Fi, Wi-Max etc).

Wireless Gigabit Alliance (Wi-Gig).

Designed to drive a global ecosystem of interoperable products.

Wi-Gig SpecificationData transmission rate upto 7Gbps.

Supports low-power handheld devices.

Support for Beamforming.

Widely used advanced security and power management for WiGig devices.

Structure of Wi-Gig

Physical Layer(PHY)Enables low power and high

performance WiGig devices.

Medium Access Control (MAC) LayerSupports Advanced usage models.

Protocol Adaption Layers(PALs)Allows wireless implementations.

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.

Medium Access Control(MAC)layer

Network Architecture, Power Management, Advanced Security.

Protocol Adaptation Layer

Requirements Plasma Silicon Antenna used. Wi-Gig Beamforming

Usage Models

ConclusionA 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.
