Wireless Network vs Wired Network: Advantages and Disadvantages
Increasingly, the needs of modern homes and many work spaces are for greater and more versatile internet coverage than just having a single PC, or group of PCs wired up to a router with ethernet cables.
Wireless networks enable multiple devices to use the same internet connection remotely, as well as share files and other resources.
They also allow mobile devices, such as laptops, tablets and ipods to move around within the network area freely and still maintain a connection to the internet and the network.
There are also disadvantages to wireless networks, however, especially when you compare them with wired networks, which generally maintain a faster internet speed and are more secure.
Below, I have listed all of the above points, plus the other main advantages and disadvantages of a wireless network vs wired network.
It doesn't matter if it's a wireless or wired network. I think network management can be introduced that is equally sensible.— Vint Cerf
Benefits of a Wireless Network
To be happy in this world, first you need a cell phone and then you need an airplane. Then you're truly wireless.— Ted Turner
Advantages of a Wireless Network over Wired
- As I mentioned in the introduction, the main advantage of a wireless network over a wired one is that users can move around freely within the area of the network with their laptops, handheld devices etc and get an internet connection.
- Users are also able to share files and other resources with other devices that are connected to the network without having to be cabled to a port.
- Not having to lay lots of cables and put them through walls etc. can be a considerable advantage in terms of time and expense. It also makes it easier to add extra devices to the network, as no new cabling is needed.
- If you are a business such as a café, having a wireless network that is accessible to customers can bring you extra business. Customers generally love wireless networks because they are convenient.
- Wireless networks can sometimes handle a larger amount of users because they are not limited by a specific number of connection ports.
- Instant transfer of information to social media is made much easier. For instance, taking a photograph and uploading it to Facebook can generally be done much quicker with wireless technology.
Did You Know?
The world’s first wireless computer communication network, known as ALOHAnet, was created by a university professor in Hawaii named Norman Abramson in 1971. His system used cheap ham-like radios and featured seven computers located across four islands, they communicated with a central computer without the use of phone lines.
New security loopholes are constantly popping up because of wireless networking. The cat-and-mouse game between hackers and system administrators is still in full swing.— Kevin Mitnick
Disadvantages of a Wireless Network
- It can require extra costs and equipment to set up, although increasingly routers have built-in wireless capability, as do devices such as laptops, handheld devices, modern DVD players, and TVs.
- Setting up a wireless network can sometimes be difficult for people who are not experienced with computers. (Although there are issues with setting up a wired network too, off course!)
- File-sharing transfer speeds are normally slower with wireless networks than they are with cabled. The speeds can also vary considerably according to your location in relation to the network.
- The general speed of a wireless connection is also usually much slower than a wired one. The connection also gets worse the farther you are from the router, which can be a problem in a large building or space.
- Wireless connections can be obstructed by everyday household items and structures such as walls, ceilings, and furniture.
- Wireless networks are generally less secure. There can also be problems with neighbors stealing bandwidth, if the network hasn’t been set up to be password protected. Information is also less secure too and can be easier to hack into.
There is an underlying, fundamental reliance on the Internet, which continues to grow in the number of users, country penetration and both fixed and wireless broadband access.— Vint Cerf
I read recently of the advent of a completely wireless house. Having just moved house and being drowned in billions of cords and cables, that sounds like a great thing to have.— Julian Ovenden
Summary of The Advantages and Disadvantages
Freedom of movement for users
Users can access network from anywhere within range.
Users location limited by need to use cable and/or connect to a port.
Easier with wireless network as you do not need to be cabled to network, though transfer speeds may be slower.
Generally less convenient as you have to be cabled in, but transfer speeds often faster.
Far less complicated, disruptive, and untidy cabling needed.
Lots of cables and ports needed which can be a headache.
For businesses dealing with public, customers like and often expect wireless, so wireless can increase income.
Wired networks are not convenient for public use, but sometimes acceptable for a traditional office.
Usually slower than wired.
Usually faster than wireless.
Less secure than wired. Both bandwidth and information can sometimes be accessed.
More secure than wireless.
Upgrading to a wireless network can be difficult and expensive.
Can also be difficult and expensive to set up.
Questions & Answers
What is bluetooth?
Bluetooth is a standard for the short-range wireless interconnection of electronic devices, such as mobile phones, laptops, and tablets.
What are the disadvantages of a mobile network?
Compared to a wired network, there are a number of disadvantages. Here are some examples: mobile networks are generally less secure and are easier to hack into to; they tend to be slower, especially when a long way from the signal source, they tend to be less reliable as the signal can be blocked by walls, hills, people, vehicles, or adverse weather.
What is the range for using a wireless network?
There is no single answer to this question, as there is a range of wireless technologies available. A Wi-Fi wireless access point (also known as a hotspot), for example, has a range of around 20 meters (66 feet) indoors and an even longer range outdoors, but other wireless technologies can have greater or lesser ranges.
