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
|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
|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|
