Pain: Browsing on the internet with a slow connection
Agitate: The speed of your current connection is not fast enough and it’s costing you money.
Solution: LIFI or “LiFi”. There is more to fibre optic than speed, security and scalability. Li-FI has arrived as the newest form of high-speed wireless data transfer, capable of 5G speeds in short bursts; 3 times faster than current 4G networks if sustained over time that would be fine but what use is that when you want to do things like play games online or stream High Definition videos on demand? LiFi connections are secure since they are immune to conventional network threats because they use Light instead of radio communication.
ADVANTAGES OF LIFI
1.Enabling very high peak data rates.
2. The avoidance of the radio frequency spectrum.
3.Complete elimination of health concerns.
DISADVANTAGES OF LIFI
1.Restricted Range and Connectivity.
2.Conceivable Cost Implications.
3.Light Interference and Light Pollution.
COMPARISON BETWEEN LIFI AND WIFI
| Comparison | Li-Fi | Wi-Fi |
| Full form | Light Fidelity | Wireless Fidelity |
| Operation | It transmits data using light by the help of LED bulbs. | It transmits data using radio waves using wifi router. |
| Technology | Present IrDA compliant devices | WLAN 802.11/b/g/n/ac/d standard compliant devices |
| Data Transfer Speed | About 1 Gbps | Ranges from 150Mbps to maximum of 2Gbps |
| Privacy | Light is blocked by the walls hence provide more secure data transfer | Walls cannot block radio waves so we need to employ more techniques to achieve secure data transfer |
| Frequency of operation | 10, 000 times frequency spectrum of the radio | 2.4Ghz, 4.9Ghz and 5Ghz |
| Coverage Distance | about 10 meters | about 32 meters(vary based on transmit power and antenna type) |
| Data density | Work with high dense environment | Work in less dense environment due to interference related issues |
| Bare minimum Components used | LED bulb, LED driver and photo detector | Routers, Modems and access points |
| Applications | Used in airlines, undersea exploration etc | Used for internet browsing with the help of wifi hotspot |
