Introduction to LiFi and WiFi

If you’re not satisfied with how your WiFi network works, be relieved to know that there’s a new innovation called LiFi will shortly overpower normal WiFi speed. Introducing the LiFi, a new technology that is 10 to 100 times faster than the WiFi.

Now that we know LiFi will be big threat to WiFi technology , its important that we know how both are different and each outshines the other . We as users will feel the new LiFi Technology conquering the world with its state of art technology and underpinning features.

Comparison Table: LiFi vs WiFi

Lets se the table below to compare on various features and parameters –

FEATURE / PARAMETER	LI-FI	WI-FI
Technology	IrDA compliant devices	WLAN 802.11a/b/g/n/ac/ad standard
Operating Frequency	10,000 times frequency spectrum of radio	2.4 GHz , 4.9 GHz and 5 GHz
Coverage	Around 10 meters	Around 32 meters and varies on power /antennae type
Data Density	Works in high dense environment	Works in less dense environment
Privacy	Light is blocked by walls , hence more secured.	RF signal cant be blocked by walls , hence less secured
Data Tranfer Speed	Faster transfer speed (>1 Gbps)	Slower transfer speed (150 Mbps)
Medium of Data Transfer	Light as the carrier	Radio spectrum is carrier
Spectrum Range	Light has spectrum 10000 times broader than radio frequency	Radio frequency spectrum is much less than light spectrum
Cost	Cheaper than Wifi due to – 1 – No license required for light band 2 – Lower installation cost	Cheaper than Wifi due to – 1 – License required for radio band 2 – Higher installation cost
Ecological impact	Low	Medium
Market Maturity	Low	High
System components	Lamp driver, LED bulb (lamp) and photo detector will make up complete LiFi system.	requires routers to be installed, subscriber devices(laptops, PDAs, desktops) are referred as stations
Applications	Used in airlines, undersea explorations, operation theaters in the hospitals, office and home premises for data transfer and internet browsing	Used for internet browsing with the help of wifi kiosks or wifi hotspots
Merits(advantages)	Interference is less, can pass through salty sea water, works in densely region	Interference is more, can not pass through sea water, works in less densely region
