Gi-fi

Gigabit wireless technology is the world’s first transceiver integrated on a single chip that operates at 60GHz on

the CMOS process.

Features of gi-fi

• ten times faster than Wi-Fi

• it’s chip delivers short-range multi-gigabit data transfer in an indoor environment

• 5 gigabits per second, low power consumption, usually within a range of 10 meters .

History of gi-fi

• It was first introduced by Melbourne University researchers have achieved up to 5Gbps data transfer rates on a wireless chip.

• The world's first Gi-Fi wireless network chip developed at Australia's peak federal technology incubator has entered its commercialization phase.

Gi-fi chips

• Span 0f 10 meters

• Easy video sharing

• Multi gigabit data transfer in an indoor environment

• 5 gbps

• 5*5mm

• Placed in various devices

• 2watts of power with an antenna

Evolution of networks

Gi-fi access devices

• Cellular phones

• Computers

• Printers

• Headsets

• Fax machines etc.,

Advantages of gi-fi

• Transmits at a very high frequency of 60GHz

• Mixing and filtering keeps the signal strong

• Profitable chip

• Small in size

• Low power consumption

• Highly secured
