In the digital era, as wireless networks continue to evolve, WIFI technology, one of our primary means of daily connectivity, is also undergoing constant upgrades. Over the past few years, WIFI5 has been the preferred standard for many users, providing us with reliable wireless connections. However, WIFI6 has now emerged, introducing a range of new features and being hailed as "High Efficiency WIFI." Let's delve into the differences between WIFI6 and WIFI5, explore the advantages brought by this new technology, and consider the position of WIFI5 in this technological evolution.
Compared to the currently prevalent WIFI5 technology, WIFI6 demonstrates superior performance in multiple aspects. WIFI6 not only boasts faster speeds, support for more concurrent devices, and lower latency but also operates with greater energy efficiency. It adopts OFDMA technology similar to 5G, combined with 1024-QAM high-order modulation, enabling a maximum support of 160MHz bandwidth and nearly tripling the speed compared to WIFI5. Through intelligent frequency division technology, WIFI6 can accommodate concurrent connections for more devices, increasing the access device capacity by four times. Moreover, the reduction of queuing phenomena is facilitated by multi-device concurrent connections, actively avoiding interference and reducing latency by two-thirds. During terminal device standby, WIFI6 also supports on-demand wake-up functionality, effectively reducing the power consumption of terminal devices by 30%. These advanced features make WIFI6 a significant technological upgrade in the current field of network communication.
Under the WIFI5 standard, communication between devices can be likened to a single-channel transmission, where at any given moment, only one device can communicate with the router. Even if other devices are idle, they cannot transmit data simultaneously. If any device experiences interference, the entire communication channel may be affected, similar to a blockage in the entire communication process. In contrast, under the WIFI6 standard, communication has been improved. Multiple devices can communicate in a more flexible manner simultaneously, forming a more efficient multi-user transmission. Devices can be grouped into teams, and each team can independently transmit data without interfering with each other. If a particular device experiences interference, only the team to which that device belongs will be affected, without impacting the entire communication process. This makes the WIFI6 standard more powerful and reliable in the face of interference.
To enhance the device access capacity of WIFI networks in densely populated scenarios such as exhibition venues and sports stadiums, WIFI6 has introduced a technology known as BSS coloring. In traditional WIFI communication, devices adhere to the "listen before talk" principle, meaning they wait until other signals on the same channel are detected to be finished before initiating communication. However, BSS coloring technology allows devices to assess whether other signals might impact communication through specific markers. If a WIFI6 device reads the marker and determines it as "non-impactful," it will initiate communication directly, thereby reducing wait times and effectively improving the speed and reliability of wireless networks.
This is a significant improvement, but WIFI5 devices do not support this technology. WIFI5 devices do not carry markers in their transmitted signals, so surrounding devices cannot determine from these unmarked signals whether they might affect their own communication. The only solution is to remain silent, leaving time for these older devices that do not support the new technology.
In such a scenario, once WIFI5 devices initiate communication, it may force WIFI6 devices, which could have communicated, to remain silent. This highlights the advantages of adopting WIFI6 in high-density environments, while traditional WIFI5 devices become a limiting factor for overall communication efficiency.
In summary, WIFI6, as the new standard for wireless connectivity in the digital era, is favored by many users due to its higher speed, support for more concurrent devices, low latency, and low power consumption.
