For those who are just looking to set up their first wireless networks, there are lots of terms that can complicate issues.
One of these terms is ‘built-in’ wifi. To put it simply, it means that your device has wireless capability built into to the device.
For a more in-depth discussion, please read on.
So, What Is This ‘Built-in’ Wi-Fi?
Before we can answer the question, it is probably best to clearly define what wifi is and what it is used for.
Wifi is basically a way that devices can connect to either, without wires, using radio waves. It is considered much more convenient than a wired connection because it is easy to add new devices to a wifi network without having to trail wires around your house.
Also, in an age where many devices are portable, wifi allows users to be anywhere in the network and still be connected. This can allow you to use one device in multiple locations in your home.
Most devices nowadays access the internet using wifi. In fact, most hotels, cafes, restaurants, offices, and many homes will have wifi networks.
These networks, especially those found around a home, often work by having one router that connects to a modem. The router sends out a wifi signal and allows other devices in the vicinity to access the wireless network and therefore, the internet.
The only requirement is that these devices need to also be wireless compatible. This is where ‘built-in’ wifi comes in.
What Is ‘Built-in’ Wifi?
Built-in wifi simply means that the device you are looking at comes with wifi connectivity. You won’t have to buy any extra adapters to access a wifi network as the device already comes with a way of connecting to a wifi network.
Nowadays, pretty much all laptops, smartphones, and tablets come with ‘built-in’ wifi. However, if you are using an older computer (or your built-in wifi has broken), you can buy a USB adapter to give your computer wireless connectivity.
As well as this, some device such as smart TVs and games consoles came with wifi capability that would only work when paired with a separate USB adapter. These devices are known as wifi ready devices.
Alternatively, if you are using a device that doesn’t have a USB port but does have an Ethernet port, you could connect an access point to the device with an Ethernet cable to give a device wifi capabilities.
When looking at a product with built-in wifi, or even when looking to buy an adapter it is important to know which wireless standard the device uses.
Nowadays, the most common standards are 802.11n and 802.11ac, with 802.11ac being the most recent of the two. Because it is the most recent, 802.11ac offers the fastest speeds over your network. This can help improve the speed of things such as file transfers over your network.
It is also worth knowing that while these standards are backwards compatible, if you choose to use a 802.11n adapter with a 802.11ac router. You will be limited to the speeds provided by the slower 802.11n adapter.
