Cable to Wi-Fi; Wi-Fi to GI-FI

By Enterprise Networking Mag | Thursday, November 29, 2018

For many years, optical fibers or the cables technology have played a vital role in faster transmission with a higher bit rate. Later, this technology caused several difficulties. The technological advancements in all area of human life have resulted in new data transmission facilities like wireless technology. Wi-Fi and WI-MAX have gained more attraction, as there has been no recent growth in these technologies that are able to transfer data at a high speed, and this has led to the emergence of a new technology—GI-FI.

GI-FI is integrated on a single chip that can function at 60GHz on the CMOS process, and it can ensure wireless exchange of data like audios and videos up to 5GB per second. GI-FI is the first transceiver in the world. It contains a 1mm wide antenna with 2watts of power to transfer data over a short distance, which is placed in a 5mm square chip. The GI-FI technology generally aims at a future with completely wireless office and home. The device is much smaller so that it can be embedded within any system or device.

The researchers from NICTA have started developing this GI-FI technology in the 57-64GHz unlicensed frequency band as the millimeter-wave range of spectrum allows the integration of very small high gain arrays as well as high component on-chip integration. With the use of this technology, an entire high-definition movie can be sent to mobile within seconds, and the phone can upload the same to the personal computer at the same speed.

GI-FI uses only low-cost chips allowing the technology to be readily integrated with multiple devices. The chip may cost only $10 or less to build. This advantage will allow companies to incorporate this technology into smartphones and other devices without involving much cost. Security would be another factor which makes this technology much possible to capture more market in the current scenario. One of the most threatening problems that were faced by using the cable technology was the complexity for connecting the devices, but GI-FI ensures more simplicity in connection with the devices without causing connectivity issues compared o the cable technology.

The future is expected to see much more advancements in the GI-FI technologies enabling wireless connectivity for streaming HD videos or images between a source device and high definition devices.
