Lifi Vs Wi-Fi Speed: What’s The Difference?

(doylc.com) - Lifi Vs Wi-Fi Speed: What’s The Difference?

Introduction

The Internet is a powerful tool for communication, entertainment, and commerce. It has allowed us to reach far and wide and to access almost limitless amounts of information with just a few clicks. However, that doesn’t mean that everything is perfect when it comes to internet access. There are two main types of internet connections that we use today – LiFi and Wi-Fi. In this article, we will discuss the differences between LiFi and Wi-Fi and which one offers the best speed, security, and reliability.

What is LiFi?

LiFi is a relatively new technology that uses light to transmit data. It was first proposed by Professor Harald Haas of the University of Edinburgh in 2011. LiFi is a form of Visible Light Communication (VLC) and utilizes Light Emitting Diodes (LEDs) to send data at speeds up to 224Gbps. Unlike Wi-Fi, LiFi does not require a router or modem to transmit data and is an alternative to traditional radio frequency-based networks. LiFi is also considered to be more secure than Wi-Fi as it can be used to create a point-to-point connection that is not accessible from outside the room.

What is Wi-Fi?

Wi-Fi is a wireless computer networking technology that is used to connect devices to the Internet. It is based on the IEEE 802.11 standard and uses radio frequency waves to transmit data. Wi-Fi networks are usually secured with passwords and encryption, but it is possible to access public networks without any authentication.

LiFi vs Wi-Fi Speed

The speed of a LiFi connection is much faster than that of a Wi-Fi connection. The theoretical maximum speed for a LiFi connection is 224Gbps, while the theoretical maximum speed for a Wi-Fi connection is only 7Gbps. This means that LiFi is capable of transferring data at a much faster rate than Wi-Fi.

Security

When it comes to security, LiFi is considered to be more secure than Wi-Fi. Since LiFi uses light to transmit data, it is not possible for an outsider to intercept the signal, as is possible with Wi-Fi. LiFi also has the advantage of being able to create point-to-point connections, meaning that data is not accessible from outside the room.

Reliability

When it comes to reliability, both LiFi and Wi-Fi have their advantages and disadvantages. Wi-Fi is more reliable in terms of distance and range, as it is able to transmit data over larger distances than LiFi. On the other hand, LiFi is more reliable in terms of interference, as it is not susceptible to interference from other devices using the same frequency as the Wi-Fi network.

Cost

When it comes to cost, LiFi is more expensive than Wi-Fi. This is because LiFi requires special hardware and software to be installed in order to use it, while Wi-Fi can be used with off-the-shelf routers. Additionally, LiFi is not available everywhere, while Wi-Fi is much more widely available.

Conclusion

In conclusion, LiFi offers much faster speeds, better security, and more reliable connections than Wi-Fi. However, it is more expensive to set up and is not available everywhere. Depending on your needs, either LiFi or Wi-Fi could be the better option for you.
