How does Wi-Fi 7 compare to Wi-Fi 6/6E and why upgrade to Wi-Fi 7?
Wi-Fi 6 (IEEE 802.11ax standard) was primarily focused on delivering increased
capacity through multi-user technologies such as OFDMA and MU-MIMO. Building
upon this, Wi-Fi 6E extended the application of these capabilities, for the
first time, into wider and more abundant channels within the unlicensed
spectrum of the 6GHz band. Wi-Fi 7 builds upon these enhancements and further
surges performance, particularly in terms of low latency, extremely high
throughput, and even greater capacity through the most efficient use of
spectrum.
Wi-Fi 7 offers several improvements over Wi-Fi 6/6E. It doubles the channel
bandwidth to 320MHz, enhances throughput and capacity with 4K QAM modulation,
and introduces Multi-Link Operation (MLO) and efficiency updates like preamble
puncturing. These advancements enable reduced and consistent latency, even in
congested environments. Wi-Fi 7 is designed to support immersive and
bandwidth-intensive applications for home and enterprise
environments.
What is Multi-Link Operation (MLO) in Wi-Fi 7 and how does it work?
Multi-Link Operation is a key feature of Wi-Fi 7 that brings significant improvements in throughput, latency, and reliability. In the past, Wi-Fi client devices like smartphones were limited to operating on a single channel within the 2.4GHz, 5GHz, or 6GHz band. However, with the introduction of Wi-Fi 7 MultiLink Operation (MLO), clients can now utilize multiple links across frequency bands.
Simultaneous Multi-Link Operation allows traffic to be aggregated across multiple bands, resulting in peak throughput and low latency, while alternating Multi-Link Operation dynamically switches traffic between bands to avoid wireless interference, ensuring deterministic and predictable low latency even in heavily congested environments.
Qualcomm Technologies’ expert implementation of Multi-Link technology is at the heart of realizing massive gains in performance, including the most powerful multi-link client implementation called High Band Simultaneous Multi- Link (HBS Multi-Link), as well as mesh Wi-Fi networking with Qualcomm® Multi- Link Mesh technology.

What is High Band Simultaneous (HBS) Multi-Link and what advantages does it
offer?
The implementation of Multi-Link Operation methods known as High Band
Simultaneous Multi-Link (HBS Multi-Link) offers exceptional benefits in terms
of capacity, stability, and latency. HBS Multi-Link utilizes the high bands,
which includes the 5GHz and 6GHz unlicensed radio bands with wide channels,
including channels up to a peak 320MHz in the 6GHz band. With HBS Multi-Link,
Wi-Fi 7 client devices like smartphones and PCs can establish two simultaneous
high band channels and combine the throughput of both links to achieve
significantly higher data rates and reliable connections. In regions where the
6GHz band is not available or 320MHz channels are not supported, HBS Multi-
Link allows for the aggregation of available channels to maximize capacity.
FastConnect 7800 with HBS Multi-Link is a key differentiator for next-gen
smartphones, PCs, XR devices, and more, as it can enable the full performance
of Wi-Fi 7 globally and optimizes the potential of both the increasingly
accessible 6GHz spectrum and regions with only 5GHz availability, leaving the
2.4GHz spectrum for legacy Wi-Fi, Bluetooth, and IoT.

How does Qualcomm Multi-Link Mesh harness Multi-Link Operation?
Multi-Link Operation is especially powerful in the context of mesh Wi-Fi.
Qualcomm Multi-Link Mesh harnesses this Wi-Fi 7 innovation to introduce a new
approach to mesh networking, reshaping the management of backhaul and
fronthaul mesh connections by replacing these dedicated connections with
dynamically managed links. Through intelligent selection, aggregation, or
alternation of links based on network conditions, this technology enables both
legacy devices and the latest Wi-Fi 7 connected devices to achieve
deterministic low latency and optimal throughput. As a result, users can enjoy
virtually lag-free gaming experiences, seamless video streaming, and smooth
collaboration even in today and tomorrow’s highly congested Wi-Fi network
environments. Qualcomm Multi-Link Mesh is a key feature enabled by Qualcomm Wi
Fi 7 networking platforms.

What advantages does a 320MHz channel offer?
Wi-Fi 7 is the first standard to support super-wide 320MHz channels, which is
twice the size of the maximum channel width in previous generations. This
significant expansion in channel width is one of the most notable performance
enhancements offered by Wi-Fi 7 and the 6GHz band. It enables double the data
transfer rates compared to previous Wi-Fi standards, paving the way for multi-
gigabit throughput to client devices such as smartphones, PCs and XR devices.
This groundbreaking advancement empowers users like gamers and content
creators to enjoy the freedom of untethering themselves from wired
connections.
Although 320MHz offers immediate advantages to Wi-Fi 7 users, it’s important to note that not all Wi-Fi 7 devices can support this implementation of the standard. Fully featured implementations of the Wi-Fi 7 standard, such as the FastConnect 7800, have the capability to support this feature.

What is Wi-Fi CERTIFIED 7™?
Launched in January 2024, Wi-Fi CERTIFIED 7 is an industry certification
program
built on the IEEE 802.11be technology. Developed by the Wi-Fi Alliance, a
global
network of member companies, the Wi-Fi CERTIFIED 7 interoperability
certification
program ensures that Wi-Fi 7 devices adhere to stringent standards for
seamless
connectivity and interoperability. This certification program supports a
thriving
ecosystem of advanced devices worldwide, guaranteeing consistent
implementation
of cutting-edge features that push the boundaries of wireless connectivity and
deliver exceptional user experiences.
Leading the way in this Wi-Fi revolution, Qualcomm Technologies’ Wi-Fi 7 solutions, the FastConnect 7800 and Qualcomm Networking Pro Wi-Fi 7 Series tri-band and quad-band platforms, are among the first products to achieve Wi- Fi CERTIFIED 7. These solutions not only underwent rigorous testing to meet the highest standards but also serve in the test bed for the certification program itself.
Can Wi-Fi 7 devices support Standard Power operation in the 6GHz band?
While many countries around the world have enabled low-power Wi-Fi 6E and WiFi
7 operation in the 6GHz band, the U.S. and Canada have also enabled a higher
performance, longer-range version of 6GHz operation with the Standard Power
(SP) operating class. Standard Power access points are able to transmit up to
sixty-three times stronger signal, enabling end users to benefit from a
higher-power, longer-range version of 6GHz Wi-Fi indoors. Standard Power
operation also allows 6GHz Wi-Fi access points to operate outdoors, opening
the door for many use cases such as wireless internet service provider (WISP),
campus, and outdoor event venue coverage. It’s important to note that in order
to ensure coexistence with incumbent users in the 6GHz band, Standard Power
access points are required to consult with an Automated Frequency Coordination
(AFC) system before operating at standard power levels.
