Ethernet Cable vs Wi-Fi


The huge development of computer technology has been seen in the past 20 years, and sometimes you feel that the latest achievements are out of date. Computers have become smaller, lighter and more powerful. The scale of the hard disk is bigger and the life expectancy is longer than any other time. Today, the only thing that hasn’t changed is how computers connect to the Internet. When we choose between Wi-Fi and Ethernet, we often get confused.

What is Ethernet Cable and What Is Wi-Fi

What is Ethernet Cable

Ethernet cable is one of the most commonly used network cables in wired networks. Ethernet cables connect devices in local area networks, such as PCs, routers and switches. Considering that these are physical cables, they do have their limitations. They can stretch in distance and still carry the appropriate signals with their durability. Ethernet cables are similar to telephone cables, but they are larger and have more wires. Ethernet cables have different colors, but telephone cables are usually gray.

What is Wi-Fi

Wi-Fi is a wireless network protocol that allows devices to communicate without interconnections. It is technically an industry term, representing a wireless local area network (LAN) protocol based on 802.11 IEEE network standard. Wi-Fi is the most popular way to transmit data in a fixed location. It is a trademark of the Wi-Fi Alliance, which is an international company association involving wireless LAN technology and products.

Ethernet Cable vs Wi-Fi: What’s the Difference

Then what’s the difference between Ethernet cable and Wi-Fi?

Ethernet Cable vs Wi-Fi: Speed vs Standards

So far, you may be more optimistic about your Wi-Fi, but here are some technical facts you may need to know about Wi-Fi and Ethernet:

Wi-Fi standards such as 802.11ac and 802.11n provide a maximum speed of 866.7 Mb / s and 150 Mb / s respectively. But it is hard for you to realize that a large part of this bandwidth because it is also used by our Wi-Fi router for other purposes. Similarly, there are standards for Ethernet cables, such as CAT5, CAT5e, CAT6 cables, etc., all of them belong to patch cables. In theory, if you have CAT6 cable, wired Ethernet connection can provide up to 10 Gb / s rate.

Ethernet Cable vs Wi-Fi: Latency

If you are a gamer, you must know how annoying delays are in online games. Moreover, it is obvious that Ethernet provides the advantage of lower latency in the war between Wi-Fi and Ethernet. Because when the Wi-Fi connection is sent around your home, your router uses radio waves. The strength and consistency of these radio waves can be reduced by obstructions in your home, interference from other devices, and the distance between your router and the connected device. These issues can cause latency.

Ethernet Cable vs Wi-Fi: Interference

The most disadvantage of Wi-Fi is interference. As technology takes over the world, we have wireless interference in our homes, including Wi-Fi routers, TVs, ovens, smartphones, game consoles, etc. This interference will not keep your Wi-Fi signal from other signals that affect your Wi-Fi. However, Ethernet cables have no such effect.

Ethernet Cable vs Wi-Fi: Security

Intruding Wi-Fi networks is easier to access than having access to physical cables. Data on Ethernet can only be physically accessed to device access to the network. These devices, including laptops at one end and routers at the other end, need be protected by firewalls. With Wi-Fi, the data is in the air. If you are using an open network, all the data you send and receive can be intercepted, including personal information and login details.


Finally, Ethernet provides better speed, lower latency, and more reliable security. Wi-Fi provides convenient advantages and it is sufficient for most purposes. Therefore, you just need to see if your device is suitable for the type that Ethernet will affect it, and then decide whether it will produce enough differences to run some cables.
