Hello friends Summarized! Do you already know about WiFi 7? WiFi 7 is the latest WiFi technology that will be released next year or no later than 2024. WiFi 7 offers various advantages compared to WiFi 6, one of which is a very high data transfer speed . But what exactly is WiFi 7? And how does Wifi 6 compare to WiFi 7? Let's see the explanation in this article!
Definition of Wi-Fi 7
WiFi 7 is the popular name for the IEEE 802.11be Extremely High Throughput (EHT) standard. This standard is a development of WiFi 6 (802.11ax) which has been around since 2019. The goal of WiFi 7 is to improve the performance and efficiency of WiFi networks in dense and varied environments, such as offices, hospitals, airports, stadiums, and so on.
WiFi 7 brings several new features that make it superior to WiFi 6, including:
- Ultra-wide bandwidth of 320 MHz, which allows Wi-Fi channels to be wider and can accommodate more data.
- The 4096-QAM high-level modulation scheme, which allows each data symbol to carry more bits, thereby increasing data transfer rates.
- Multi-RU, which allows WiFi routers to divide channels into resource units (RU) that can be dynamically allocated to connected devices, thereby increasing spectrum efficiency and network capacity.
- Multi-Link Operation (MLO), which allows WiFi devices to operate on three frequencies at once (2.4 GHz, 5 GHz and 6 GHz), thus enabling devices to send and receive data simultaneously and simultaneously in various frequency bands and channels.
What is WiFi 7 and How Does Wifi 6 Compare to Wifi 7?
WiFi 7 vs WiFi 6 comparison
The following is a comparison table between WiFi 7 and WiFi 6:
| Feature | Wi-Fi 6 | Wi-Fi 7 |
|---|---|---|
| Maximum speed | 9.6Gbps | 46Gbps |
| Channel bandwidth | 20, 40, 80, and 160 MHz | Up to 320 MHz |
| Frequency | 2.4 GHz and 5 GHz | 2.4 GHz, 5 GHz, and 6 GHz |
| Modulation | OFDMA with 1024-QAM | OFDMA by extension and 4096-QAM |
| MIMO | UL/DL MU-MIMO with up to 8 x 8 antennas | UL/DL MU-MIMO with up to 16×16 antennas |
| RU | Multi-RU | Multi-RU |
From the table above, we can see that WiFi 7 has an initial theoretical data transfer rate of up to 46 Gbps , while WiFi 6 has a theoretical maximum of only 9.6 Gbps . WiFi 7 also doubles the channel bandwidth of WiFi 6 from 160MHz to 320MHz . This is important because wider channels handle more traffic.
In addition, WiFi 7 also supports the 6 GHz frequency, which is a new frequency band that is cleaner and less noisy than the 2.4 GHz and 5 GHz frequencies. With MLO, WiFi 7 can intelligently switch between frequencies and channels to improve connection stability.
WiFi 7 also uses the 4096-QAM high-level modulation scheme, which allows it to carry 12 bits/symbol which is theoretically 20% higher than 1024-QAM WiFi 6 which only gets stuck at 10 bits/symbol . WiFi 7 also increases the number of MIMO antennas from 8×8 to 16×16 , which means it can serve more devices simultaneously.
Benefits of WiFi 7 for Future Needs
With all the advantages that WiFi 7 has, of course there are many benefits that we can feel in the future. Some of the benefits of WiFi 7 include:
- Stream 4K/8K video without lag, buffering or image quality compromise.
- Play cloud gaming without lag, delay or dropouts.
- Access high-quality, immersive Augmented Reality (AR) and Virtual Reality (VR) content.
- Support various cloud computing needs, such as teleconferencing, telemedicine, telecommunication, and so on smoothly and stably.
- Supports the development of the Internet of Things (IoT), smart home, smart city, and other advanced technologies that require a fast and reliable WiFi connection.
Conclusion
WiFi 7 is the latest WiFi technology that will be coming soon next year or no later than 2024. WiFi 7 offers various advantages compared to WiFi 6, such as very high data transfer rates, larger channel bandwidth, more frequencies, more modulation efficient, and more powerful MIMO. WiFi 7 also provides many benefits for future needs, such as 4K/8K video streaming, cloud gaming, AR/VR, cloud computing, IoT, and so on.
