Gi-Fi technology vs wifi | difference between gi-fi and wifi
This page compares Gi-Fi technology vs WiFi and mentions difference between gi-fi and WiFi technologies. It mentions applications of gi-fi technology.
Gi-Fi is the Gigabit Wireless technology. It operates at frequency band from 57 GHz to 64 GHz with bandwidth of about 7GHz. It is developed mainly for high speed data communication applications such as video. The idea came after the development of wifi 802.11b and wimax 802.16e where in video transfer used to take more time. Gi-Fi technology is based on IEEE 802.15.3c standard.
The Gi-Fi technology is used for short range data communication at speed of 5Gbps in a coverage distance of 10 meters. The entire Gi-Fi transceiver has been designed and developed with square of 5 mm in size. It houses antenna, transmitter and receiver on a single chip using CMOS technology. Antenna has dimension of 1mm in size on the chip.
Following are the important aspects of Gi-Fi over existing WiFi and Mobile WiMAX.
These are important difference between these wireless technologies.
• It supports 5Gbps speed which is almost ten times faster compare to existing
technologies.
• It has lowest power consumption.
• It has very low cost, which is one tenth compare to existing technology products.
• As it operates in point to point mode, it provides very high security.
Gi-Fi technology applications
Following are the applications of Gi-Fi technology:
• It offers very fast synchronization between devices and hence it enables
very fast video transfer.
• It creates wireless PAN network which is used by PDAs, cell phones, printer, headphones, notebook PCs etc.
• It is used in Inter-Vehicle Communication systems and
Ad Hoc type of networks.
• Due to high speed of operation it can replace application of HDMI cable based wireless
data transfer.
• Used for video signal broadcasting.
