This presentation summarizes the Gi-Fi (GigaFit) technology. Gi-Fi allows wireless transfer of audio and video data at speeds up to 5 gigabits per second using the 60GHz frequency band. It provides 10 times the maximum wireless transfer rate within a 10 meter range. The presentation includes information on the Gi-Fi chip, how it works using Time Division Duplexing, its features like low power consumption and small size, potential applications, and concludes that Gi-Fi is expected to become the dominant wireless technology for networking within a few years.

- 3. 3 Introduction Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a single chip that operates at 60GHz on the CMOS process. Gi-Fi allows wireless transfer of audio and video data up to 5 gigabits per second. Gi-Fi is ten times the current maximum wireless transfer rate usually within a range of 10 meters. It supports standard of IEEE802.15.3c Mangal.com 4/4/2014

- 6. 6 Why Gi-Fi ? The bit rates of Bluetooth is 800 Kbps and Wi-Fi has 11 Mbps Both are having power consumptions 5mw and 10mw The lower frequency of operation 2.4GHz. so, to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology Mangal.com4/4/2014
- 7. 7 Bluetooth v/s GI-FI Characteristics Bluetooth Gi-Fi SPECIFICATION AUTHORITY Bluetooth SIG NICTA DEVELOPMENT START RATE 1998 2004 PRIMARY DEVICE Mobile phones, Electronics Devices Mobile phones, Home devices, Electronics Office, Industrial Devices Power Consumption 5mw < 2mw Data transfer rate 800Kbps 5 Gbps Range 10 meters 10 meters Frequency 2.4GHz 57-64GHz Mangal.com4/4/2014
- 8. 8 Working Of Gi-Fi • Use Time Division Duplex (TDD) for both transmission and receiving. • Data are up converted from IF range to RF 60Ghz range by using 2 mixers and we will fed this to an power amplifier, which feeds millimeter wave antenna. • incoming RF signal is first down converted to an IF signal centered at 5 GHz and then to normal data ranges Mangal.com4/4/2014
- 9. 9 Continue…… • use heterodyne construction for this process. • due to availability of 7Ghz spectrum the total data will be transferred within seconds. Mangal.com4/4/2014
- 11. 11 Time Division Duplexing (TDD)• Transmit signal is separate from receiver by the allocation of different time slot. • Single frequency channel is assign to both the transmitter and receiver . • In this, there are allocated time slot for both transmitter and receiver. Mangal.com4/4/2014
- 13. 13 Why 60GHZ? Millimeter wave antenna which will operate at 60Ghz frequency which is unlicensed band, because of this band, We Are achieving high data rate energy propagation in the 60GHz band has unique characteristics that make possible many other benefits such as excellent immunity ,high security . Point –to-point wireless system operating at 60GHz have been used for many years for satellite–to-satellite communication. this is because of high oxygen absorption at 60GHz. Mangal.com4/4/2014
