Difference between WiFi and GiFi
1. Wireless Fidelity (Wi-Fi) :
Wi-Fi is a wireless networking technology which allows devices such as computers, mobile devices and other electronic equipment to interface with the Internet. Wireless high speed Internet and network connections are provided by using radio waves. By the help of wireless router internet connectivity occurs. It is a wireless network protocols based on the IEEE 802.11 standards. Mainly it refers to wireless LAN technologies.
2. Gigabit Fidelity (Gi-Fi) :
Gi-Fi or gigabit wireless refers to a wireless transmission system. Gi-Fi provides a data rate of more than one billion bits per second. It is faster version of Wi-Fi. In general, as we will see it is ten times faster than WiFi technology. Gi-Fi technology is the transceiver of the world integrated on a single chip which operates at 60GHz using CMOS process. Gi-Fi defined in IEEE 802.15.3C standard.
Difference between Wi-Fi and Gi-Fi :
|01.||Wi-Fi uses radio frequency waves for data transmission over air.||Gi-Fi uses millimeter waves for data transmission over air.|
|02.||Frequency range of Wi-Fi is 2.4 GHz and/or 5 GHz.||Frequency range of Gi-Fi is 57 to 64 GHz.|
|03.||Wi-Fi provides a data rate/speed of 150 Mbps and more.||Gi-Fi provides a data rate/speed of 5 Gbps and more.|
|04.||Its coverage range is larger.||Its coverage range is smaller.|
