Wireless connectivity: understand Wi-Fi 6 and expectations around Wi-Fi 7
Between the present reality of Wi-Fi 6 and the future promises of Wi-Fi 7, Brazil positions itself at the frontier of wireless network technology
Brazil has been the scene of continuous advances in wireless connection technologies. The evolution of Wi-Fi is driving changes in the way we access the internet, and Wi-Fi 6, which has been gaining popularity, has revolutionized the way people connect. However, as we discuss these transformations and the next generation of wireless standards, it is worth noting that despite product development TP-Linka global leader in connectivity solutions, at the launch of this technology, the new Wi-Fi standard is not structured in any country in the world.
Wi-Fi 7 technology
Wi-Fi 7, 802.11be technology, which represents a step forward in the evolution of wireless networks, is being eagerly awaited due to its promise of speeds of up to 46 Gb/s, that is, ultra-fast transmission with greater efficiency aimed at environments that demand high performance, such as event and entertainment sectors, as well as the gaming public in general, and large crowded places, such as shopping malls and airports, and also large industries, as they are examples of sectors that require a large amount of bandwidth.
However, its large-scale acquisition requires a gradual process and the adaptation of existing infrastructure. The widespread implementation of a technology takes a significant period of time and requires effective collaboration between the public and private sectors. This involves measures such as reducing trade restrictions and appropriate regulation. However, Wi-Fi 6, 802.11ax technology, has become a reality in many homes, promoting data transmission capacity, improved energy efficiency and lower latency.
Ayrton Neves, Director of Channels at TP-Link explains that: “Imagine that in an orchestra each musician represents a data transmission channel, in previous versions of Wi-Fi, we had fewer musicians and instruments, so we could only play a limited amount of notes at the same time. In Wi-Fi 7, with more musicians and instruments, we can play more notes at the same time, and each musician is able to play notes faster and with greater complexity. This means that Wi-Fi 7 can send and receive much more data at the same time, much faster than previous versions.”
Ayrton shared his enthusiasm regarding the current scenario: “Wi-Fi 6 represents a significant advancement in terms of technology, providing users with a notably more stable and faster connection experience. We are seeing an increase in the adoption of this technology in Brazil, with a growing demand for routers compatible with this specification, which reflects the search for better quality and performance internet.”
The ability to effectively manage multiple devices promises to revolutionize connectivity in environments where bandwidth demand is intense. As the infrastructure adapts, it is likely that Wi-Fi 7 will gradually find its way into homes and domestic environments, providing users with an even faster and more reliable connection experience, but the greatest emphasis and benefits will be aimed at industry.
Wi-Fi 6 and its advantages
Wi-Fi 6 also represents a notable advancement compared to previous versions, including Wi-Fi 5. The technology represents an improved experience for Brazilian families, who can enjoy more stable and effective connectivity when using multiple devices simultaneously, without the performance drops that used to be common in previous versions. This evolution has the potential to transform the way people experience connectivity in their homes, offering a faster and more efficient experience.
Higher non-Wi-Fi 7 speeds
However, when it comes to Wi-Fi 7, Ayrton clarifies: “While Wi-Fi 7 promises even more impressive speeds and virtually instantaneous responsiveness, we must be realistic about deadlines. The country’s network infrastructures, regulations and device update cycle imply that the implementation of Wi-Fi 7 in Brazil will not be a reality in the short term. This process is complex and could take several years before the benefits of Wi-Fi 7 are widely available to Brazilian users.”
The director of TP-Link highlights the importance of building a solid foundation with Wi-Fi 6 before looking to the future: “Focusing on Wi-Fi 6 now is essential to ensure the country is ready for the next generation. We are committed to bringing the most modern and efficient to our consumers with our line of Access Points, Mesh Routers and Repeaters, always with a close eye on the reality of the Brazilian market, paving the way for a future of increasingly more networks. robust and safe.”
Wi-Fi 6 features
OFDMA (Orthogonal Frequency-Division Multiple Access):
A key technology in Wi-Fi 6, OFDMA allows a channel to be efficiently used by multiple devices at the same time. Imagine a highway, while previous versions of Wi-Fi allowed only one “car” (device) per lane at a time, creating congestion, OFDMA divides that highway into several smaller lanes. This allows multiple cars (devices) to travel at the same time in their own lanes improving speed and decreasing latency.
Target Wake Time (TWT):
This functionality helps improve the energy efficiency of devices. It works like a smart alarm clock, in previous versions of Wi-Fi, devices such as a smartphone or tablet had to “wake up” regularly to check if there was data to receive or send, which constantly consumed energy. With Wi-Fi 6 TWT, each device can schedule a specific time to wake up and communicate with the router. This means devices can “sleep” for longer periods when they are not actively using the network, saving energy, lowering consumption and extending battery life, making it particularly useful for Internet of Things (IoT) devices and mobile devices. that operate on battery.
MU-MIMO in Uplink and Downlink:
Traditionally, Wi-Fi routers could communicate with only one device at a time, even though the data exchange was fast enough to appear simultaneous. MU-MIMO changes this by allowing the router to communicate with multiple devices at the same time. Using the acronym “Multiple User, Multiple-Input, Multiple-Output”, the function increases the efficiency and speed of the network, reducing waiting time for each device.
While Wi-Fi 5 also supports MU-MIMO, it only does so for downlink (from router to devices). Wi-Fi 6 expands this to also include uplink (from devices to the router), enabling simultaneous two-way communications and faster uploading.
BSS Coloring:
This feature helps reduce interference in environments where many Wi-Fi networks operate close to each other. Think of it as assigning a unique digital “color” to each Wi-Fi network, making it easier for devices to identify and connect to their own network without being confused or disturbed by signals from neighboring networks. This improves network efficiency and connection quality in places heavily populated by Wi-Fi networks, such as apartment buildings or offices.
Wi-Fi 6 Efficiency
In other words, although Wi-Fi 5 is also efficient, Wi-Fi 6 was specially designed to work better in environments with many connected devices, offering greater capacity and efficiency, especially in the current period of technological expansion. According to FGVcia (Center for Applied Information Technology), there are 464 million digital devices (computer, notebook, tablet and smartphone) in use in Brazil, which require routers and devices that offer high-level connectivity.
