Gi-Fi vs. WiFi: A Technology Comparison

gi-fi wifi wireless technology data communication comparison

This article compares Gi-Fi technology with WiFi, highlighting the differences between them. It also touches on the applications of Gi-Fi technology. Gi-Fi stands for Gigabit Wireless technology.

It operates in the frequency band from 57 GHz to 64 GHz, boasting a bandwidth of approximately 7 GHz. Gi-Fi was primarily developed for high-speed data communication applications, especially video. The concept emerged after the development of WiFi 802.11b and WiMAX 802.16e, where video transfer was often time-consuming. Gi-Fi technology is based on the IEEE 802.15.3c standard.

Gi-Fi technology is designed for short-range data communication, achieving speeds of up to 5 Gbps within a coverage distance of 10 meters. The entire Gi-Fi transceiver has been designed and developed to be just 5 mm square in size. Using CMOS technology, it houses the antenna, transmitter, and receiver on a single chip. The antenna itself measures just 1 mm on the chip.

Here are the key advantages of Gi-Fi over existing WiFi and Mobile WiMAX technologies. These points outline the primary differences between these wireless technologies.

  • Speed: It supports speeds of 5 Gbps, which is almost ten times faster than existing technologies.
  • Power Consumption: Gi-Fi has the lowest power consumption.
  • Cost: It has a very low cost, roughly one-tenth of existing technology products.
  • Security: Operating in point-to-point mode provides very high security.

Gi-Fi Technology Applications

Here are some key applications of Gi-Fi technology:

  • Fast Synchronization: It enables rapid synchronization between devices, facilitating very fast video transfer.
  • Wireless PAN: It creates a wireless Personal Area Network (PAN) used by devices like PDAs, cell phones, printers, headphones, and notebook PCs.
  • Inter-Vehicle Communication: It’s utilized in Inter-Vehicle Communication systems and Ad Hoc networks.
  • HDMI Replacement: Due to its high speed, it can replace HDMI cables for wireless data transfer.
  • Video Broadcasting: Used for video signal broadcasting.
