Introduction to Gi-Fi :Introduction to Gi-Fi :

Gi-Fi or Gigabit Wireless is the world's first Gi-Fi or Gigabit Wireless is the world's first transceiver integrated on a single chip that operates at transceiver integrated on a single chip that operates at 60GHz on the CMOS process.60GHz on the CMOS process.

Gi-Fi allows wireless transfer of audio and video data Gi-Fi allows wireless transfer of audio and video data up to 5 gigabits per second.up to 5 gigabits per second.

Why Why Gi-FiGi-Fi ? ?

The reason for pushing into Gi-Fi The reason for pushing into Gi-Fi technology is because oftechnology is because of

slow rate,slow rate,high power consumption,high power consumption,low range of frequency operation low range of frequency operation

of earlier technologies i.e. Bluetooth and Wi-Fi.of earlier technologies i.e. Bluetooth and Wi-Fi.

Disadvantages of Bluetooth & Wi-FiDisadvantages of Bluetooth & Wi-Fi

The bit rates of Bluetooth is 800 Kbps and Wi-Fi The bit rates of Bluetooth is 800 Kbps and Wi-Fi has maximum of 11 Mbpshas maximum of 11 Mbps

Both are having power consumptions 5mw and Both are having power consumptions 5mw and 10mw 10mw

The lower frequency of operation 2.4GHz.The lower frequency of operation 2.4GHz.

so, to have higher data transfer rate at lower so, to have higher data transfer rate at lower power consumption we move onto Gi-Fi technology.power consumption we move onto Gi-Fi technology.
