The Sixth Generation Of Communication Networks Is Going To Enter The World Of Communication And Information Technology In 2030 When Wi-Fi 7 Is One Step Away From Being Released.
While these two wireless technologies are not directly related to each other, and the sixth generation is supposed to provide access with the lowest delay and the highest speed, on the other hand, Wi-Fi 7 promises the possibility of implementing powerful wireless local networks.
More precisely, when you buy a router that supports the sixth generation of communication networks and then implement a wireless local area network based on Wi-Fi 7, you will have access to the highest level of productivity and access to network resources.
While users and companies have just started migrating to Wi-Fi 6 and others are considering upgrading to Wi-Fi 6E, it seems that the successor of these two standards is coming and will experience significant improvements like its predecessors. Slow, the most important are faster connections, less delay, and the ability to manage more relationships.
While Wi-Fi 6 offers a relative increase in speed compared to Wi-Fi 5, Wi-Fi 7 allows for high-speed connections.
The Wi-Fi 7 standard is called the 802.11be EHT standard, where EHT stands for Extremely High Throughput.
Although the technical specifications of the above technology are still under investigation, the new standard can achieve transfer rates of 10 Gbps. To be more precise, Wi-Fi 7 will be about four times faster than Wi-Fi 6 and Wi-Fi 6E.
The Wi-Fi 7 standard naming process is based on the same system as the previous one and is called IEEE 802.11be. Just as Wi-Fi 6 became known as IEEE 802.11ax, and Wi-Fi 5 became known as IEEE 802.11ac. Wi-Fi 7 is fully compatible with previous standards, but you must use equipment compatible with the above-average to benefit from new features and improve performance.
To be more precise, you need to buy new routers and access points and consumer devices such as smartphones, laptops, TVs, and new equipment. In addition to high speed, Wi-Fi 7 uses new technologies to reduce latency, increase capacity, and improve network performance.
What capabilities do Wi-Fi 7-based networks provide us?
Wi-Fi 7 has a competitive advantage over Wi-Fi 6 in speed and connections and can implant work with high performance, low latency, and more reliability. Such benefits make transferring high-volume videos or playing games over the web possible without problems. In addition, applications will have access to high throughput and low latency.
Another important area that Wi-Fi 7It focuses on is solving the problem of congestion and interference when simultaneously sending data packets through wireless clients. This feature helps companies define stable networks when networks decide to transmit data in areas with dense devices or areas that consist of different networks that overlap with each other. High speed, low latency, and support for more connections are two big achievements of Wi-Fi 7 for local networks.
Wi-Fi speed 7
The first thing to consider about Wi-Fi 7 is that it offers more channel bandwidth than Wi-Fi 6. Almost every generation of Wi-Fi that comes out increases the number of bands available between routers and client devices. For this reason, if the 2.4 GHz band becomes too crowded, Wi-Fi 6E-enabled devices can switch to the 5 GHz or 6 GHz bands. However, the bandwidth of these bands may also be subject to interference and other noise. The key to solving this problem is to increase the channel width.
Wi-Fi 6’s channel width increased from 80 MHz in Wi-Fi 5 to 160 MHz. Wi-Fi 7 will double the channel width to 320 MHz in the 2.4, 5, and 6 GHz radio bands. In addition, Wi-Fi 7 uses a new technology called puncturing to prevent the problem of interference in a part of the channel and make it unusable.
Do we need Wi-Fi 7?
The bandwidth of cellular networks is continuously increasing to meet the needs of users and industrial units; as a result, if we intend to use this bandwidth in enterprise networks and reduce our dependence on wired Ethernet networks, we need a technology that To provide us with the ability to use the brilliant benefits of 6G networks optimally.
Today, most of the devices and routers we use are limited to Wi-Fi 5, which is nearly ten years old, and the interesting thing is that Wi-Fi 6 is new for many users and companies. Even a few consumer devices, such as smartphones, can support it. Are of the above standard. With this description, why is the telecommunications industry so interested in introducing new wireless technology? As we mentioned in the article, “The sixth generation of communication networks is going to bring about a big change, big events will happen in the world of technology, and a wide range of equipment equipped with high-speed wireless chips will be released on the market in ten years. They need regular and high-speed communication.
Today, technologies such as video conferencing or Internet of Things equipment are used in a limited way in some companies and homes, but their popularity will grow dramatically in the coming years. This issue also applies in the field of trade and industry. Where industrial IoT equipment such as sensors and monitoring systems can quickly reach the limits of current Wi-Fi standards, in almost a few years, most houses and especially the residential complexes, will be equipped with smart speakers, smart lighting systems connected to the network, smart electrical outlets and hundreds of other devices, all of which can connect to the Internet.
Wi-Fi 7 can respond to this need for consumer equipment by providing higher speed, lower delay, and improved interference management. In addition, low latency and better stability in establishing Wi-Fi-based local connections will enhance the productivity of industrial and manufacturing units.
What are the differences between Wi-Fi 6 and 7?
One of the first questions that preoccupy our minds about the launch of Wi-Fi 7 is the difference between Wi-Fi 6 and 7 standards. 7th generation Wi-Fi uses three bands of 2.4, 5, and 6 GHz, but it performs better than Wi-Fi 6 and will have a more stable performance using existing technologies. Among the important differences between these two standards, the following should be noted:
Wider channels
Each band is divided into several channels. The 2.4 GHz band consists of 11 20 MHz tracks, while the 5 GHz band has 45 ways, but instead of being limited to 20 MHz, it can combine 40 or 80 MHz channel widths. The 6 GHz band took a step forward and supports 60 channels, while in Wi-Fi 6E, the channels reach a width of 160 MHz. Wi-Fi 7 supports channels that have a maximum width of 320 MHz. The wider the track, the more data can be transmitted. A simple analogy would be that you have a single-lane road compared to a multi-lane highway. Now, which one drives the highest amount of traffic? The wider the Wi-Fi bands and channels, the more data they can transfer.
Higher QAM
Quadrature Amplitude Modulation (QAM) efficiently sends and receives data through radio frequency waves. The higher this value is, the more information is transmitted in an aggregated form. Wi-Fi 7 supports the 4K-QAM standard, while Wi-Fi 6 was limited to 1024-QAM and Wi-Fi 5 was limited to 256-WAM. The potential advantages of the above technology are that the amplified signal strength, background noises, and complex interferences do not significantly increase the amount of signal loss. 1024-QAM in Wi-Fi 6 has increased the data transfer rate by about 25% compared to Wi-Fi 5, while 4K-QAM in Wi-Fi 7 will provide a 20% increase to make the data transfer process even faster.
Multilink Operation
One of the most interesting developments in Wi-Fi 7 is Multilink Operation (MLO). Wi-Fi standards establish a connection between two devices on a single band. A tri-band 6E Wi-Fi router connects two devices on the same band to the network through a fixed channel, and the router decides to join the 2.4, 5, or 6 GHz band.
Multilink operation technology can combine multiple frequencies across bands into a single connection. As a result, Wi-Fi router 7It can connect to a Wi-Fi 7 device simultaneously through two or more channels in different bands. Multilink operations create wider channels and allow them to carry more data. Here, the criterion is not to achieve higher speed but to make more efficient use of available media and bandwidth.
Routers that support Wi-Fi 7 can check for congestion and other interference and use the best channel to send data to maintain a stable connection and low latency. Andy Davidson, Qualcomm’s expert, says: “I don’t expect Wi-Fi 7Mandatory use of 6 GHz spectrum. For this reason, areas that have limited high-band scope go to the use of simultaneous multilink technology. In short, this technology creates wider channels up to 320 MHz by combining or aggregating smaller channels. Qualcomm believes this feature can help Wi-Fi 7 achieve higher throughput and lower latency.
“In our tests, the simultaneous high-band multiplexing technique made it possible to achieve an effective channel of 240 MHz in Wi-Fi 7 without allocating a 6 GHz spectrum,” says Davidson.
In short, Wi-Fi 7 reduces latency by simultaneously using different frequency bands and channels. The multilink operation capability is handy when the network condition drops drastically due to external interference or congestion caused by neighboring devices.
When will Wi-Fi 7 be available to us?
While Wi-Fi 7 is expected to be officially introduced to the technology world in 2023 or 2024, it will take at least two or three years for the first consumer devices and routers to support Wi-Fi 7 .are about to be released to the market, but the big companies active in the field of making chips and modems for mobile devices have been working for a long time.
For example, Qualcomm has unveiled its Wi-Fi 7 chip and Networking Pro Series platform, which can stream a maximum transfer of 33 Gbps in a quad-band connection on 16 channels. It is ready to provide the corresponding license to its partners.
If you are interested in new technologies such as virtual and augmented reality, this standard and its low rate should attract you. Qualcomm believes that virtual worlds can lead us all to Wi-Fi 7, but we must wait and see what happens.
Broadcom and MediaTek have also introduced Wi-Fi 7 technologies. However, once Wi-Fi 7 is introduced, users will still favor Wi-Fi 6 for a long time, and the two technologies will likely co-exist as complementary technologies for years to come.
