A router acts as a firewall, and prevents most connections coming in from the internet. These are the cables used to connect network devices to a router or a switch. There are many clients on the market supporting MU-MIMO now, and it's predicted that by the end of , all new clients will support this technology.

Think of a Wi-Fi client as a device that has an invisible network port and an invisible network cable. This metaphorical cable is as long as the range of a Wi-Fi signal broadcast by an access point. The type of Wi-Fi connection mentioned above is established in the Infrastructure mode , which is the most popular mode in real-life usage. Technically, you can skip an access point and make two Wi-Fi clients connect directly to each other, in the Adhoc mode.
However, as with using a crossover network cable, this is rather complicated and inefficient. This is the radius an access point's Wi-Fi signal can reach. Typically, a good Wi-Fi network is most viable within about feet from the access point.
This distance, however, changes based on the power of the devices involved, the environment and most importantly the Wi-Fi standard. The Wi-Fi standard also determines how fast a wireless connection can be and is the reason Wi-Fi gets complicated and confusing, especially when considering the fact there are multiple Wi-Fi frequency bands.
These bands are the radio frequencies used by the Wi-Fi standards: Generally, the 5 Ghz band delivers faster data rates but a little less range than the 2. Note that a 60 GHz band is also used but only by the Depending on the standard, some Wi-Fi devices use either the 2. Wi-Fi standards decide the speed and range of a Wi-Fi network.
Generally later standards are backward compatible with earlier ones. This was the first commercialized wireless standard. It offers a top speed of 11 Mbps and operates only on the 2. The standard was first available in and is now totally obsolete; It's also now obsolete, though it's still supported by new access points for backward compatibility.
Introduced in , the The standard offers the top speed of 54 Mbps but operates on the 2. It's used by many older mobile devices, such as the iPhone 3G and the iPhone 3Gs. This standard is supported by access points of later standards. Available since , The standard operates on both 2. There are two types of dual-band routers: On each band, the Wireless-N standard is available in three setups, depending on the number of spatial streams being used: This in turns creates three types of true dual-band routers: N each of the two bands offers a Mbps speed cap , N one band has a Mbps speed cap while the other caps at Mbps and N each of the two bands allows up to Mbps cap speed.
In order to create a Wi-Fi connection, both the access point router and the client need to operate on the same frequency band. For example, a 2. Also, a Wi-Fi connection takes place on just one band at a time. If you have a dual-band capable client such as the iPhone 6 with a dual-band router, the two will connect on just one band, likely the 5 Ghz.
Sometimes referred to as 5G Wi-Fi , this latest Wi-Fi standard operates only on the 5 GHz frequency band and currently offers Wi-Fi speeds of up to 2, Mbps or even faster with latest chip when used in the quad-stream 4x4 setup. The standard also comes with the 3x3, 2x2, 1x1 setups that cap at 1, Mbps, Mbps and Mbps, respectively.
Technically, each spatial stream of the In real-world testing so far, with the same amount of streams, I've found that Note that the real-world sustained speeds of wireless standards are always much lower than the theoretical speed cap.
This is partly because the cap speed is determined in controlled, interference-free environments. The fastest peak real-world speed of an On the same 5 GHz band, That said, all First introduced in , the Prior to that, it was considered a different type of wireless networking. Operating in the 60 Ghz frequency band, the It can't penetrate walls very well, either. For this reason, the new standard is a supplement to the existing It's an ideal wireless solution for devices at a close range, with a clear line of sight no obstacles in between such as between a laptop and its base-station, or a set-top box and a big screen TV.
This is the next generation of Wi-Fi, set to supersede However, it's the first standard that focuses not only on faster speed but also on Wi-Fi efficiency, especially in crowded air space. In other words, Ultimately, this means it allows for higher ratio of real-world speed versus theoretical ceiling speed. It's also said to reduce energy consumption by two thirds compared to That said, consumer devices that support Wi-Fi designations are the way networking vendors market their Wi-Fi routers in an effort to differentiate between them.
Since there are so many Wi-Fi standards and tiers, the designations can be confusing and don't always accurately indicate the speeds of the routers. As mentioned above, the top commercial speed of However, in June , Broadcom introduced a new And also for this reason, This designation basically means it's an AC-enabled router that offers a combined wireless speed on both bands equal to the number. With more and more advanced Wi-Fi chips being developed, That said, let me state the rule of thumb one more time: The speed of a single network connection one pair is determined by the slowest speed of any of the parties involved.
That means if you use an In order to get the top Also right now, the fastest This means getting routers of higher designations are unlikely to bring you benefits in Wi-Fi speeds. This means that, unlike a dual-band AC router that has one 2. In other words, a tri-band router, for now, is basically an AC router with an additional With two separate 5 Ghz bands, both high- and low-end clients can operate in their own band at their respective top speeds without affecting each other.
On top of that, two 5 Ghz bands also help reduce the stress each places on the band when there are many connected clients fighting for the router's bandwidth.
Also known as AC, this designation was introduced in An AC router is a tri-band router two 5 Ghz bands and one 2. Each of the 5 Ghz bands have a peak Wi-Fi speed of 2, Mbps and the 2.
Also known as AC, this new designation shares the same Wi-Fi chip as the AC above but in a dual-band setup, the router has one 5 Ghz band 2, Mbps cap and one 2. This is the latest designation starting with the availability of the This means the router has the top speed on the 60 Ghz band In wired networking, a connection is established the moment you plug the ends of a network cable into the two respective devices.
In wireless networking, it's more complicated than that. Since the Wi-Fi signal broadcast by the access point is literally sent through the air, anybody with a Wi-Fi client can connect to it, and that might pose a serious security risk. So only approved clients can connect, the Wi-Fi network should be password-protected or in more serious terms, encrypted. Currently, there are a few methods used to protect a Wi-Fi network, called "authentication methods": The former is for compatibility, allowing legacy clients to connect; the latter allows for faster connection speeds and is more secure but works only with newer clients.
From the side of the access point or router, the owner can set the password or encryption key that clients can use to connect to the Wi-Fi network. If the above paragraph seems complicated, that's because Wi-Fi encryption is very complicated. The most popular implementation of WPS is via push-button. Here's how it works: On the router's access point side, you press the WPS button.
Then, within two minutes, you must press the WPS button on your Wi-Fi client and you'll be connected. This way you don't have to remember the password encryption key or type it in. Note that this method works only with devices that support WPS. Most networking devices released in the last few years do, however. This is a standard that enables Wi-Fi clients to connect to one another without a physical access point.
Basically, this allows one Wi-Fi client, such as a phone, to turn itself into a "soft" access point and broadcast Wi-Fi signals that other Wi-Fi clients can connect to. This standard is very useful when you want to share an internet connection.
For example, you can connect your laptop's LAN port to an internet source, such as in a hotel, and turn its Wi-Fi client into a soft AP. Now other Wi-Fi clients can also access that internet connection. Wi-Fi Direct is actually most popularly used in phones and tablets, where the mobile device shares its cellular internet connection with other Wi-Fi devices, in a feature called personal hotspot.
It's designed to handle Wi-Fi bandwidth efficiently, hence iy is capable of delivering better data rates to multiple connected clients simultaneously.
Since a router typically has more Wi-Fi power than a client in a particular wireless connection, the router is hardly used at full capacity. For example, a three-stream When the two are connected, the router still uses the entire 1, Mbps transmission to the phone, wasting Mbps.
This is similar to going to a coffee shop to get a small cup of coffee and the only option is the extra large. With MU-MIMO, multiple simultaneous transmissions of different Wi-Fi tiers are sent to multiple devices at the same time, enabling them to connect at the speed each client needs. As stated above, be aware that in a few countries, it may be a crime to use someone else's wi-fi connection without their permission. In many countries like in much of the UE and most states in the USA, it is perfectly legal to use open wifi connections without explicit permission.
Software companies like Ubuntu, Apple and Microsoft seem to agree with this since you can configure their software to automatically connect to open wifi without any user action. While some people do not want to share their wifi connections, they almost always put a password on their connections. Many people are now deliberately leaving their wifi connections open so that they can share with their neighbors.
That said you should always be respectful when using someone else's wifi. Don't hog the bandwidth and make it so that people regret sharing. Your tablet and computer may sometimes use the same router and internet connection, but there is no direct connection between the tablet and computer.
You can of course send things between the computer and tablet through the internet by methods such as email, but this would work even if the computer and tablet were on opposite sides of the planet. If you want to transfer material directly between the tablet and computer, the easiest way to do this is to use the tablet's USB cable.
