Moreover, scientists keep on playing their vital roles in making the current technology of every era more and more efficient and faster for more valuable and effective outcomes. Our lives have now dramatically dependent on one of the most necessary technologies called the internet.
With time, we can easily say that in the field of the internet, it has become more and more smart and useful day by day. The hard work behind its success is remarkable. After the amazing success of Ethernet, WIFI was introduced.
What is WIFI?
WIFI was created by a group that was associated with IEEE 802.11 network standards in the late 1990s. This group was connected with the non-profitable Alliance. Since then WIFI was introduced to the world and got an unbelievable response. This is something that happened beyond imagination. It was like a fiction come true that we were enabled enough for connecting to the world wirelessly. This was indeed a big achievement and invention in the history of technology. Wifi is basically a wireless network that is capable of connecting multiple devices via a single connection to the internet and itself. It is a combination of different wireless protocols that are generally based on IEEE 802.11 network standards. This network standard keeps on working for better and better advancements to make the wifi more useful cum efficient.
For the past two decades, we can easily observe that people are amazingly attracted to and addicted to the use of WIFI. And why not people get used to such an invention when it automatically gets involved in all our routine life plans and activities? It seems unrealistic and strange if we visit somewhere and we wouldn’t find WIFI at that place. From basic needs of life to managing numerous life issues, from medical treatment appointments to shopping everything has become a click-away fortune. Hence we need a WIFI to perform our little or big tasks every day.
What is WIFI 6?
WIFI of the 6th generation is generally termed as the WIFI 6 of Wireless Local Area Network (WLAN). It is compatible with the Institute of Electrical & Electronics Engineers (IEEE) 802.15.4. In this article further, we will discuss the detailed working, features, benefits, advancements, achievements, etc.
The basic functionality of WIFI 6 is as similar to the normal WIFI which is to connect multiple devices at a time. However, WIFI 6 is as much efficient as it can connect numerous devices at a time with amazing bandwidth using a single router or any of the internet sources.
WIFI was the last technology introduced before WIFI 6 and as compared to WIFI 5 here at the current situation WIFI 6 is working four times more effectively and faster than WIFI 5. WIFI 6 contains an advanced feature of WIFI 5’s (MIMO) Multiple – In – Multiple – Out technology. Moreover, WIFI 6 has the ability to work on both 2.4 GHz & 5GHz. These two are the present standard frequencies. It is expected that in the near future companies can also avail the working of WIFI 6 from 1GHz to 6GHz. This expectation indicates that the companies can plan to invest in this to achieve the target of connecting a wide range of devices to be connected via one source using WIFI 6.
In addition to this, for the first time in the history of WIFI, it offers Orthogonal Frequency Division Multiple Access (OFDMA) instead of Orthogonal Frequency Division Multiplexing (OFDM). Orthogonal Frequency Division Multiple Access (OFDMA) has indeed boosted the features of WIFI 6.
Some examples are underneath:
⦁ By reducing the latency and enhancing the service quality the overall effect of the performance becomes more efficient as per the demand and need.
⦁ Furthermore, it has also improvised the user end experience as it can connect multiple varieties of devices with the same single connection. This kind of performance surely attracts the audience and gathers a great response in return.
⦁ Hence it benefits the business and all sorts of companies financially.
The efficiency of WIFI 6
WIFI 6 is capable of handling a wide number of WIFI devices connected to the same network. Furthermore, have a look at its functionality and how it handles the pressure.
⦁ It has made it easier for a router to connect with more than one device within the same network.
⦁ It can send data to a variety of devices at the very same time at once.
⦁ It allows WIFI devices to set up anytime to check in with the selected/ ongoing router.
The actual secret behind the efficiency of the WIFI 6 is basically because of these two technologies that are: Multi-user, multiple-input, multiple-output technology (MU-MIMO) and Orthogonal Frequency-Division Multiple Access (OFDMA). Additionally, while connecting to a single device, MU-MIMO enables routers to get involved with several numbers of devices at the same time. As per the record and observation, it is said that previously WIFI 5 MU-MIMO allows the routers to get connected with four devices at maximum. However, now with WIFI 6, it has the ability to get connected with a double number of devices simultaneously. That’s such a big development indeed. On the other hand, OFDMA allows an individual transmission to send data to all the other different devices that are connected via the present network simultaneously. It is really an outstanding advancement introduced by WIFI 6 using OFDM.
Features of WIFI 6
Amazingly WIFI 6 has introduced some high-quality and extremely useful features that will dramatically overcome all the issues and fulfill the needs of the users and businesses regarding internet usage. Moreover, it keeps on expanding the feature of adding as many devices to be connected at the same time as time passes. The significant characteristics that are introduced to make the advancements reachable can be understood by this pictorial representation.
Target Wait Time (TWT)
WIFI users and Apps are supposed to decide and set the time for upcoming connectivity plans via Target Wait Time (TWT) approach. This act can activate the radios of the reserved devices to keep on inactivation mode until the decided time. Hence devices are supposed to be connected only during the allotted time slot via a wireless network. However, this approach would create a mess and problem for the IoT devices due to their approach of not maintaining constant connectivity seems quite unimportant. In addition to this, this feature can save cost and benefits IoT devices as well by timely managing the connectivity timings. Hence this approach also saves the battery life of the individual device as its wireless connections consume the battery rapidly.
Basic Service Set (BSS) Coloring
This feature of the technology makes a difference between the BSS of the access points and their users on a similar radio frequency channel.
1024-QAM (Quadrature Amplitude Modulation Mode)
This feature of WIFI 6 is a very high-profile modulation scheme. Furthermore, it has the capability to increase the throughput speed by 25%. This feature is basically designed for the wide range spectrum that covers a huge area. Such as malls, stadiums, and transportation stations/hubs. Etc.
Multiple-User, Multiple-In, Multiple-Out (MU-MIMO) and Transmit Beamforming
This feature was initially introduced to the earlier versions of WIFI while it’s now being standardized by the authorities during WIFI usage/ launch. This feature manages multiple devices via access points at the same time of connectivity.
WIFI Protected Access 3 (WPA3)
This feature indicates the happenings seen that how the connection responds when it comes to the password-protected internet connection. WIFI 6 supports WIFI-protected access and proves the security of the devices that are connected along with the security of the personal information. This feature also gives a platform to improve cyber security implementation.
Orthogonal Frequency Division Multiple Access (OFDMA)
This feature helps in increasing the network’s current condition while enhancing the network capacity and minimizing congestion. The system of OFDMA is designed in such a way that it will eventually divide WIFI service into lower channels to spread the broadcast from individual subchannels. However, it still allows broadcasting from different users.
By experiencing the above-mentioned features, a user can get the below-mentioned three key benefits that are provided by the WIFI 6 when it is working on any of the compatible devices.
Faster Data Transmission
Firstly, with the incredibly introduced features, the most beneficial thing that happened to the internet world is the fast speed that enables every sort of download and uploads to be done within microseconds. This advantage helps in boosting the business and workflow. The speed is noticed 40% higher than the speed of previously launched WIFI 5.
Improved Battery Life
Secondly, WIFI 6’s remarkable features make the battery life of the WIFI 6-compatible devices such as mobiles, tablets, computers, and other smart devices long-lasting. It automatically follows the start and sleeps time of the connection by the Target Wait Time approach.
Higher Capacity in Dense Networks
Finally, connectivity of a wide number of devices sometimes becomes a hassle. Especially at such places where WIFI is needed in several different areas and numerous devices are supposed to be connected. Such as hospitals, malls, etc. this situation can be elaborated as a dense situation that makes the network dense as well. But now thanks to the WIFI 6 this issue has been resolved by connecting a wide range of devices without any delay and breakdown.
After the above-detailed discussion, it is easily concluded that WIFI 6 has made the internet world more efficient by making the wide and connectivity options advanced, fast, and smart. Moreover, it is beneficial with respect to the time, cost, and outcome altogether for all kinds of internet users.
