WiFi 6 was born to offer better connectivity, so that more devices can connect at the same time, offering information to all of them at the same time, without queues.
WiFi 7 is the next generation of wireless networking, delivering faster network speeds and greater bandwidth efficiency compared to earlier versions like WiFi 6 and WiFi 5.
WiFi 7 features include ultra-fast 320 MHz channels, 4096 Quadrature Amplitude Modulation (QAM) and Multi-Link Operation (MLO). These features allow for faster data speeds and greater ability to connect to devices simultaneously.
Ultra-fast 320 MHz channels
Ultra-fast 320 MHz channels are one of the key features of WiFi 7. These channels are wider and have higher capacity than the channels used in earlier versions of WiFi. This allows WiFi 7 routers to offer higher performance and higher capacity.
The 320 MHz channel bandwidth on the 6 GHz band enables data rates twice as fast as Wi-Fi 6E, which means higher data rates. This is particularly important for applications that require a large amount of data, such as online gaming or high-definition video streaming.
However, the use of wider channels also poses challenges. In the past, wider channels were impractical due to spectrum restrictions that could prohibit the use of part of the band. With WiFi 7, Multi-RU and Puncturing technologies allow WiFi 7 devices to take full advantage of the remaining portion of channels that are not being used or interrupted, enabling efficient use of bandwidth and faster data transmission. fast and reliable.
Quadrature Amplitude Modulation (QAM) 4096
Quadrature Amplitude Modulation (QAM) is a technique used in transmitting data signals over a network. WiFi 7 uses a 4096-bit Quadrature Amplitude Modulation (QAM) technique, allowing more data to be more densely embedded in each signal.
QAM modulation consists of joining several bits of information into a single symbol, and then transmitting that symbol over the network. The greater the number of bits that can be encoded in a symbol, the greater the transmission efficiency. 4096 QAM allows 4096 different combinations of bits to be encoded in one symbol, which means more data can be transmitted in a single symbol. This allows for higher data transmission speeds and greater efficiency in the use of bandwidth.
multi-link operation (MLO)
Multi-Link Operation (MLO) is a feature of WiFi 7 that allows devices to simultaneously transmit and/or receive across different bands and channels. This is achieved by separating the data and control planes. With Multi-Link Operation (MLO) WiFi 7 devices can transmit and receive data across multiple bands and channels at the same time, enabling faster speeds by aggregating bandwidth and higher reliability on multiple bands used simultaneously.
Multi-Link Operation (MLO) is especially useful in environments with a large number of connected devices, where the bandwidth is divided among multiple devices. MLO allows devices to connect to multiple bands and channels at the same time, increasing data transmission speed and improving connection reliability.
Comparison between Wifi 7, 6 and 5
WiFi 7 is the next generation of wireless networks that offers faster network speeds and greater efficiency in the use of bandwidth compared to previous versions such as WiFi 6 and WiFi 5, as seen in the image above.
Some of the key features of WiFi 7 include ultra-fast 320 MHz channels, 4096 Quadrature Amplitude Modulation (QAM), and Multi-Link Operation (MLO), which enables faster data rates and greater ability to connect to devices simultaneously.
WiFi 6 focuses on anti-congestion technology designed for crowded networks. The 6GHz band was introduced, the higher bandwidth, higher capacity, higher power efficiency and latency improvements.
WiFi 5 has faster data transmission capabilities than the previous version, WiFi 4, but it does not have the same advanced features for bandwidth efficiency and performance in high device density environments as WiFi 6 and WiFi 7.
Asus routers
At CES 2023 Asus introduced two WiFi 7 routers: the ROG Rapture GT-BE98 and the ASUS RT-BE96U.
These routers are designed to offer a better connection experience, with faster data transmission speeds and greater efficiency in the use of bandwidth.
The ROG Rapture GT-BE98 is dedicated to gaming, offering very fast speeds for a lag-free experience. With up to 11,525 Mbps on the 6 GHz band, 5,762 Mbps on each of its two 5 GHz bands, and 1,376 Mbps on the 2.4 GHz band, it offers 25,000 Mbps of aggregate bandwidth.
The ASUS RT-BE96U is suitable for homes and businesses that require faster data transmission speeds.
