Mobile technology is being boosted and much in news 5G and wireless internet has reached its sixth generation. Let us look at why Wi-Fi 6 is a breakthrough technology for the IoT and why Wi-Fi 6 (802.11ax) is better than Wi-Fi 5?
Wi-Fi 6 is basically for businesses and international hotspots. This has been confirmed by none other than Cisco Vice President. According to him Wi-Fi 6 (802.11ax) is fast because high-level R&D is involved in it.
Wi-Fi 6 is a great technology in the wireless arena. It connects people to mobile devices, working of appliances used in the household, and also to public utilities and it can be used even in the case of traffic lights and power grids and it also makes for less electricity usage.
There is more a powerful technology has been introduced in the field of communication, it is called Li-Fi Technology. Data transfer is at high speeds. The data gets transferred on visible light, UV rays, and infrared rays, and that is all components of light.
When something is in its present state, then it should be only LED lights which can carry the light to its final position. Read more about Li-Fi technology.

History of internet protocols
If someone were to know about the 6 standards of internet protocol then the answer would be a satellite, Wi-Fi, radio frequency, RFID, Bluetooth, and NFC.
Now, in the standard of internet protocol with satellites, one should be aware that satellite communications enable a phone communication from a phone to the next antenna of around 15 miles which means stable connection and compatibility that is universal.
But, that takes up a lot of high power consumption, and high cost and it also means no direct conversation between phone and device and the communication channel has to go through the satellite.
If one another example was to be taken, it can be said that radio frequency is that example, and that is the easiest form of communication between both devices, and the cons are that devices cannot be connected without a lot of technology coming into play.
If you need an example of RF devices then that would be your normal TV. But, on the whole, it can be said that RF is going out of business and soon you would find this technology going out of business.
We Need Something Fast
Now, we have to see how LAN has remained the same over the years and that is about to change because Wi-Fi and IoT would threaten the state of affairs with LAN.
Now, let us see when the world moved from LAN towards Wi-Fi. It started with BYOD in enterprises. This is employee-owned devices within a business.
This is nothing except bring your own laptop to work. Although there are certain workplaces where shadow IT is used. This shadow IT means the company does not know that employees are bringing their laptops to work and if the companies do not allow personal laptops at work.
This is as if four people were traveling by car, and they all have to wait for one another to reach, now it is like four people are traveling by bus and they all reach together. Thus these bits travel faster. This happens because the bits in different channels are traveling at the same time.
Now, we have to come back to the point that the internet of things devices would enable one to find massive amounts of data on the cloud. This cloud is flexible and it would help with modifications of apps.
Now, all apps would be built in within the cloud and for example, there would be apps that one finds in retail and transportation.
Is High-Speed Internet is Myth
Now, if one were to ask about the uses of Wi-Fi 6 and IoT then we should be able to reply that these technologies give you much higher speeds, lower latency, and greater density.
These are the nuances. So, it is just not faster speed, and that is really good because we are constantly demanding better apps, better games and better videos that come on our phone and laptops. If it were only speed then this would not be looking into the future as a technology.
Also, if it were just about speed; the speed would slow down eventually down the line. But, mentioning speed is still important and the numbers are 9.6 Gbps.
But, this is just the theoretical terms and you cannot reach this speed in literal terms when you are talking practically.
You can say that this speed should not have to be the speed of one computer and it can be divided between many computers and so, it can be said that all computers would work better and with higher speed.
Advantages or Benefits Of Wi-Fi 6 (802.11ax).
- To be precise, there was a time when only 5 devices were being used on one Wi-Fi router and now there are 9 Wi-Fi devices linked to the router and in future, we will reach 50 such devices.
- Wi-Fi 6 has even more power efficiency. Wi-Fi 6 saves battery life. This is because the router needs to work lesser for the search for signals which drains the lesser battery. This feature is called Target Wake Time.
- It makes devices to get more sleep time and save on battery life, a feature that is better for IoT.
- This technology is doing best for the high-density environment such as education and offers a great user experience. The higher energy and low costs would always add up.
- The technology is being best used by enterprise IT managers who want that one should have their eye on and they should have control over everything that is linked to their router networks.
- The emails work 3 times better and faster and so do other short packets such as Skype and that is important for the internet of things even if the internet traffic comprises of bigger packets like Netflix.
- Next important thing is the great multiuser capability. The problem with Wireless networking so far has been that the signals travel too far and that problem gets solved with BSS coloring.
- This moves the contention-based protocol to the scheduled based protocol. Now, technology can easily be used in high-density environments such as stadiums and airports
Key applications Of Wi-Fi 6 (802.11ax).
- Internet of things has made augmented reality a commonplace thing.
- Provide multi-user services in highly populated places. i.e. School, collage, hospitals, and stadium.
- IoT devices consume very little battery power but still gives the best performance.
If we were to again talk about low latency in devices, we would see that there would be a latency of less than one millisecond, this technology can thus be used in medical IoT devices, augmented reality and guided vehicles.
But, that is not all, this intelligent technology can be used in all verticals. This makes every device work faster because the devices do not need to keep struggling to remain connected.
If you look at 5G internet, then you’ll see that Wi-Fi 6 and 5G internet are not to be seen as competitors but cooperation and 5G are mainly used for outdoors and it is basically for when there is no wireless and Wi-Fi is mainly for indoors.
The point always remains that mobile data and wireless networks have become very intrusive and one needs to check on that. For instance, if one were to log in to the internet in Starbucks, and the person already has a data connection but needs to log into Wi-Fi manually, then that is a safer method to work on two internet connections at the same time.
What Makes Wi-Fi 6 (802.11ax) Faster Than Wi-Fi 5?
The names of the two technologies that make Wi-Fi 6 faster are MU-MIMO and OFDMA.
MU MIMO is something used by more than one user, works on more than one input, and gives more than one output. This technology is used in good routers, and devices but it is an upgrade over Wi-Fi 6.
As of now, he said technology communicates with four laptops or phones at one point in time, and Wi-Fi 6 would make for access with up to 6 devices at one time such as phone and laptops. Thus this is like you had 4 trucks earlier and now you have 6 trucks.
The name of the other technology is OFDMA. This is as if you have one truck to go to many locations. If the truck goes 75% of the way and the customer travels the rest of the distance, similarly, the truck would be able to go the remaining 25% of the distance for the second customer who meets the truck 75% of the way. This is how your Wi-Fi would work.
Security Advancements in Wi-Fi 6
You would be glad to know that Wi-Fi gets the biggest security update for the whole 10 last years. This new security protocol is being called WPA 3.
Now, your passwords would not be hacked that easily, and if someone were to hack your passwords, then your data would reach the hackers in a format that would make it harder to use your data. For Wi-Fi 6 to work with Wi-Fi Alliance, you would need to have WPA 3 certification.
This is also a seamless method despite just being secure.
How a simple household uses the internet is when some two people are using Netflix at the same time, the next person is playing an online game, and some altogether net usage is going on.
At the same time there are some smart gadgets being operated such as a door lock, and light switches, then you should know that all these gadgets are really operating at a faster speed, but not at the top speed.
The bottom line remains how many gadgets are there on the 6G network and how much internet bandwidth do these gadgets operate on. If you were to think that old machines would operate on Wi-Fi 6 then that is wrong and the correct assumption is that one would need to buy new devices.
These new gadgets will need not just new software but also new hardware. So, you will have to suffice with new phones and new laptops.
So, it is not as game-changing as it sounds. But, sooner than later, you would see new gadgets that come with Wi-Fi by default. This would take approximately 5 years of time.
It does not take time to buy new routers though and that is more feasible than buying new gadgets. But, do not rush, and only do that when the router starts getting too slow.
What Is the Future Of Wi-Fi 6?
- Wi-Fi 6 technology will be 802.11ax enabled. Every device will have to be certified.
- The performance will be improved in Skype, voice mail and email communication.
- Better performance in streaming services like Netflix.
- Improved multi-user capability with BSS coloring.
- Embedded SIM cards will be used to enable cellular activity.
- 35 billion devices of wireless internet would be sold by 2020
If you were to ask the next question as to when the Wi-Fi 6 would get started, then you would know that these Wi-Fi 6 devices are just starting to be churned out. These are going to be very expensive though and it has not become that very common till now.
If you have already seen people having laptops and mobiles, now the people would also be buying watches with wireless internet and health monitors that one wears on the wrists.
There has been much excitement over this Wi-Fi 6 and it would come to you as a surprise that more than 35 billion devices of wireless internet would be sold by 2020 and that makes for a lot of devices, to be honest.
If you are buying a new phone then you should look for a device that has this feature. To name a few ancillary features, we would be able to say that Wi-Fi 6 comes with Qualcomm and Snapdragon. All top of the line phones is getting this feature. It is a good sign that you are looking at Wi-Fi 6 coming with these phones.
This is when the phones would need certification and soon the phones would stop needing this certification and would come established with Wi-Fi 6 and that is when the world would be ready for Wi-Fi 6. This technology is also called 802. 11 ax.
This technology is not just for private players such as Amazon and it is also for those who have a role to play in society. The world is getting ready for 5G and Wi-Fi 6.
One of the major good things about Wi-Fi 6 is that it helps in overlapping areas such as busy colleges and universities, and with this Wi-Fi 6 technology, one can easily help each network. Surprising as it might be, it saves cost on both the network and the devices on the consumer side hence resulting in a lot of savings.
Not just that, it would lead to a lot of savings in commercial centers like a supermarket. This technology is closely linked to augmented reality and virtual reality.
If you were to check for numbers and figures then you should know that the industry is going to boom from 2020 to 2022 by 2 trillion dollars to 3.47 trillion dollars
