This document discusses next generation wireless technology called Gi-Fi. It provides an introduction to Gi-Fi, describes its architecture and features, and compares it to other wireless technologies like Bluetooth and Wi-Fi. Gi-Fi uses 60GHz frequency and can achieve data transfer rates up to 5Gbps, which is faster than Bluetooth or Wi-Fi. It transmits multiple signals simultaneously across different frequencies to avoid interference. The document outlines potential applications of Gi-Fi technology in devices, offices, video transfer, vehicle communication systems, and broadcasting in sports stadiums.

9. Disadvantages of Bluetooth & Wi-Fi
The bit rates of Bluetooth is
800Kbps and Wi-Fi has 11Mbps
Both are having power
consumptions 5mw and 10mw
 The lower frequency of
operation 2.4GHz.For transferring
large amount of videos, audios,
data files take hours of time.
So, to have higher data
transfer rate at lower power
consumption we move onto Gi-Fi
technology
