How does Wifi Technology work?
Ever since the internet came into being, our day-to-day activities have become increasingly connected with this technology. From education to the corporate sphere, the internet is used worldwide to find answers to questions, solve problems, and even trade commodities from one end to the other.
Yet, we must remember that a set of technological advancements have led to worldwide access to the internet that we use for educational, entertainment, and other purposes.
One such advancement is the wireless technology of WiFi. A wireless technology that connects a number of devices by providing them with internet services. A radio signal is passed through a Wifi router that is caught by nearby devices.
Once the connectivity between a router and devices is established, internet services can be shared among devices up to a certain limit. WiFi stands for Wireless Fidelity that refers to communication services within a wireless network.
Used for mobile computing gadgets like smartphones and laptops, WiFi network technology has grown rapidly in terms of popularity and performance.
“Internet connectivity occurs through a wireless router. When you access Wi-Fi, you are connecting to a wireless router that allows your Wi-Fi-compatible devices to interface with the Internet.”
Internet Connectivity through WiFi
Since WiFi routers are not connected to devices through cables or wires, they are purely wireless when it comes to providing internet activity. This wireless network is constituted by 3 elements that are very essential to any functioning WiFi technology.
These elements are - radio signals, antenna, and router. While the radio signals connect devices to the WiFi services, the antenna helps the network catch signals.
Finally, the router is the most important element as it extends internet services to a group of devices and brings together the whole wireless network, piece by piece.

Latest WiFi Technology: Wifi 6E
Over time, Wi-Fi technology has evolved so much that various versions have been rolled out to make this technology unbeatable. The latest WiFi technology so far is WiFi 6E that we will be discussing in this blog. Let us get started.
In essence, WiFi 6E is known for its faster speed and lower latency level (lesser time to transfer signal from the router to the device). An extension of WiFi 6, WiFi 6E can be understood as an upgraded version of wireless technology.
Essentially, WiFi devices use two broadband frequencies - 2.4GHz and 5GHz. However, WiFi 6E uses a 6GHz broadband frequency to deliver upgraded performances. Moreover, WiFi 6E has also verified security controls that ensure data privacy.
“Wi-Fi 6E also has mandatory Wi-Fi Protected Access 3 security controls, which is the highest Wi-Fi Alliance security certification. “WPA3 provides the latest in security and authentication protocols. As a result, 6GHz Wi-Fi traffic is more secure than ever, and 6GHz networks are more difficult to hack.” (Source)
In fact, WiFi 6E also tends to deliver internet services with enhanced performance unlike its previous version - WiFi 6. In addition, the wireless network provided by WiFi 6E stays uninterrupted by any other networks since it can only be accessed by devices that are compatible with this wireless technology.
A class of devices is compatible with WiFi 6E which means that not all devices support this technology. That said, switching to WiFi 6E also ensures that your wireless network does not get congested by unnecessary device traffic.

Future of Wifi Technology
The internet is here to stay. And so is WiFi technology. The future of WiFi technology, in the long run, is expected to grow bigger and better. With a parallel virtual world emerging alongside our real world, the time is not far when WiFi will eventually replace all our technological needs.
As internet consumption is increasing every hour, the need to provide more and more people with internet services is also on the rise. That said, WiFi ecosystems will soon be able to accommodate more and more channels as the technology continues to evolve.
Needless, WiFi is the key to survive the virtual reality that we are currently a part of. Ever since the Covid-19 pandemic has arrived, the internet has only been a savior worldwide. Not only does it connect, but it also brings us closer.
Therefore, WiFi technology must bring out the best and escalate in terms of performance and persistence over time.
Advantages of Wifi 6E
Enough of the differences that divide the WiFi world! Let us now move on to the perks of the latest WiFi technology in-store and celebrate the advantages of WiFi 6E!
The biggest advantage that a WiFi 6E router has is its rapid speed. Internet connectivity is a basic necessity in today’s time and so, its speed has got everything to do with our day-to-day activities.
While earlier versions have faced some speed-related issues, WiFi 6E ensures that speed isn’t something that its clients have to worry about. Instead, fast Wifi 6E speed and uninterrupted signals are this technology’s forte.
Since the wireless technology under the command of WiFi 6E has superwide channels, the flow of bandwidth doesn’t get easily interrupted.
What’s more, high-speed internet also ensures that the congestion in a channel does not take place easily. Perhaps even if a number of channels are working together at the same time, they can still stream high-definition content without any interruptions.
This is also because the capacity of WiFi 6E is much larger than that of any other WiFi technology. It can support 7 main channels and 14 additional channels without any device traffic.
Before talking about the latency level of WiFi 6E, we shall first understand what latency level is. In a wireless network, latency level signifies the time it takes for a signal to reach the device from the router.
In previous WiFi versions, latency has been a major issue since signal processing is generally laid back. However, WiFi 6E has a low latency level that takes no time to transfer signals to the devices.
To be precise, the latency level of WiFi 6E ranges from 2-6 milliseconds. That is simply insane!
WiFi 6 v/s WiFi 6E
Even though WiFi 6E is merely an updated version of WiFi 6, there are some key differences that exist between the two wireless technologies. Let us explore in this segment some of these differences.
The biggest difference between WiFi 6 speed and WiFi 6e speed is that of wifi channel bandwidth. Unlike earlier, when WiFi routers used respective bandwidths of 2.4GHz and wifi bandwidth 5GHz, WiFi 6E uses a bandwidth of 6GHz.
While the escalation from 5GHz to 6GHz might not seem to be a big deal, it surely is. This is because it leads to a greater number of channels in the network.
Another difference that exists between the two is that WiFi 6E has uninterrupted signal flow as opposed to WiFi 6.
Since the channel capacity of WiFi 6 is less as compared to WiFi 6E, the signal gets divided among a number of devices that compete against each other.
However, this is not experienced in WiFi 6E. Rather, one can enjoy uninterrupted signals due to superwide channels.
The third key difference is related to connectivity. Unlike older WiFi versions that witnessed connectivity issues, WiFi 6E has a superb flow of internet that seems unstoppable. How is that possible?
Well, consistent WiFi connection is one of the major highlights of WiFi 6E as it ensures that 7 main channels receive 160MHz of bandwidth each, and 14 additional channels receive 80MHz.

To sum up, WiFi 6E is a milestone in the history of wireless technology. What started as radio waves for military operations is now a worldwide technology that is used in day-to-day lives.
As something that was only known to army personnel, the internet is consumed by the masses on a large scale. Surprisingly, wireless technology is only evolving as it continues to provide high-speed internet and minimally obstructed channels.

Despite some key differences that exist between WiFi 6 and WiFi 6E, there is no doubt that WiFi technology has touched a milestone in terms of better performance and elaborate services.
Ultimate security provisions, rapid speed, and low latency level are some of the perks that WiFi 6E provides. Yet, the sole advantage is that it has upgraded the way we use the internet. All in all, it is clearly an achievement in the realm of wireless technology.
