Modern Wireless Technology

Wifi:- Wifi represents Wireless Fidelity. In wifi, information is sent with the utilization of radio waves and a wifi switch. wifi is joined by interface issues close to passageways. Wifi is viable with WLAN 802.11 a/b/g/n/ac/ad devices. Wifi is predominantly utilized for web perusing and to make areas of interest. Wifi doesn’t function admirably in thick locales; it can’t go through water and derivation is more. Wifi signals can’t be impeded inlet dividers, so flags need to utilize safer methods to ensure information. In Wifi, the information move is around 32 meters, however, this will fluctuate as indicated by the receiving wire and transmitter power. The wifi utilizes a switch and a supporter.



Lifi:- Lifi represents Light Fidelity. In Lifi, information is sent with the utilization of light created by LED bulbs. Lifi doesn’t have interface issues like with radio transmission. Lifi is viable with IrDa devices. Lifi can be utilized in an assortment of conditions like aircraft and ocean investigation. Lifi functions admirably in thick areas and can communicate through saltwater. It has less impedance. Lifi can’t go through dividers, so information is ensured and safer.


GIFI:- Gi-Fi is a remote transmission framework that is on various occasions speedier than other innovations and its chip passes on short-range multigigabit data in a close-by environment. Gi-Fi is a remote innovation that ensures quick short-range data moves with paces of up to 5 Gbps inside an extent of 10 meters.
