Are you trying to decide between WiFi and Ethernet for your home or business network? Look no further! In this article, we will explore the differences and similarities between these wired vs wireless network technologies, including how they work, their types, benefits, and drawbacks. We’ll provide a comparison chart and let us help you make an informed decision about which technology is right for you.

Introduction 

In today’s world, you must be hearing words like WiFi and Ethernet everywhere. Why not? Because these are the two most often used technologies that make all your devices connect to the internet in a matter of seconds. when we compare these wired vs wireless networks, both technologies have their own set of advantages and drawbacks, and the choice of which one to use depends on the specific needs and requirements of the user.

What is Wifi?

According to Wikipedia, WiFi (short for wireless fidelity) is a wireless networking technology that allows devices to connect to the internet or to each other without the need for physical cables. WiFi uses radio waves to transmit data between devices, and it operates in the 2.4 GHz and 5 GHz frequency bands.

How do they work?

When a device connects to a WiFi router, it sends a request to join the network. If the ISP approves the request, then the router assigns the device an IP address and assigns it to a specific network. This now allows the connected device to communicate with the router and provide access to the internet.

For example, Let’s suppose a device, such as a laptop, wants to connect to the Internet or another device using Wi-Fi. First, turn on the WiFi of that device, then the device searches for available Wi-Fi networks in its proximity; all the available networks will be displayed, and the user selects the one he or she wants to connect to. The selected Wi-Fi network sends a request to the Wi-Fi router or access point. It authenticates the device and assigns it an IP address. Now the user’s device can communicate with other devices on the same Wi-Fi network or access the Internet through the router. The router communicates with the Internet through a wired connection, such as a DSL or cable modem.

Types of Wifi

There are several different types of WiFi, including:

• WiFi 4 (also known as 802.11n): This is an older standard that operates in the 2.4 GHz frequency band and has a maximum speed of 600 megabits per second (Mbps).
• WiFi 5 (also known as 802.11ac): This is a newer standard that operates in the 5 GHz frequency band and has a maximum speed of 1.3 gigabits per second (Gbps).
• WiFi 6 (also known as 802.11ax): This is the latest standard, which operates in the 2.4 GHz and 5 GHz frequency bands and has a maximum speed of 9.6 Gbps.

Benefits of Wifi

• Convenience: One of the biggest benefits of WiFi is its convenience. Since there are no long wires involved in connecting to WiFi, which makes it truly wireless. You can connect to the internet anywhere within the range of a WiFi router or access point.
• Mobility: Another advantage of WiFi is that it allows you to take your devices with you and connect to the internet wherever you go. This is especially useful for laptop users who need to work while on the move.
• Compatibility: Because almost every device nowadays has an inbuilt WiFi system, it is simple to connect a wide range of devices to the internet. 

Drawbacks of Wifi

• Range: One of the main drawbacks of WiFi is that it has a limited range. The range of a WiFi connection is typically around 30-50 feet, depending on the strength of the signal and the number of walls or other obstacles between the device and the router.
• Interference: Since WiFi runs on radio frequency, this can make it vulnerable to interference from devices that run on the same frequency bands, such as cordless phones, other WiFi routers, radios, etc. This might result in a slower or less reliable connection.
• Security: WiFi can also be less secure than other types of internet connections, as it is easier for hackers to intercept data transmitted over a wireless connection.

What is Ethernet?

Ethernet is another most used type of networking technology that allows devices to communicate with each other over a physical connection. They work on the principle of transmitting data in the dorm of digital signal signals with the help of twisted pair cables or fiber optic cables. It is also a fast and reliable way to connect devices to the internet.

How do they work?

When a device connects to an Ethernet switch or router, it sends a request to join the network. If the request is approved, the switch or router assigns the device an IP address and assigns it to a specific network. The device can then communicate with the switch or router and access the internet.

For example, if you want to establish an Ethernet connection, a device (such as a computer, printer, or router) must be equipped with an Ethernet port, which is a small jack (image below) that allows the device to connect to a physical cable. Once you locate the jack, push the cable connector inside the jack until you hear a click. If the signal is found and the connection is properly established, you will see a green light on the LAN port.

Types of Ethernet

Just like WiFi, there are various types of Ethernet with speeds ranging from 10 Mbps to 10 Gbps, They are as follows:

• Ethernet 10BASE-T: This is an older standard that operates at a speed of 10 megabits per second (Mbps) and uses twisted pair cables.
• Ethernet 100BASE-TX: This is an upgraded version of the previous standard, this ethernet operates at a speed of 100 Mbps but uses the same type of cables i.e. twisted pair cables..
• Ethernet 1000BASE-T: This is an even faster standard that operates at a speed of 1 gigabit per second (Gbps) and also uses twisted pair cables.
• Ethernet 10GBASE-T: This is the fastest among all, it operates at a whopping speed of 10 Gbps but uses the same twisted pair cables.

Benefits of Ethernet

• Speed: The main and most obvious benefit of Ethernet is its speed. Ethernet connections are generally one step ahead of WiFi connections when we compare wifi vs ethernet in gaming, since ethernet provides better latency, and speed it is the most obvious choice for gamers.
• Reliability: Ethernet connections do not use Radio waves which makes them immune to interference from other devices or obstacles such as walls making them more reliable than WiFI connections.
• Security: Ethernet connections are generally more secure than WiFi connections, as it is more difficult for hackers to intercept data transmitted over a physical connection.

Drawbacks of Ethernet

• Limited mobility: One of the main differences between ethernet and internet wifi is that it requires a physical connection, which means that devices must be within reach of a cable. This can be inconvenient for users who need to move their devices around or take them with them when they travel.
• Compatibility: Not all devices are equipped with Ethernet ports, which can make it difficult to connect certain devices to the internet or to each other.
