Wi-Fi 7 for Business: Is It Worth Upgrading Yet?
Wi-Fi 7 hardware and equipment is now becoming more prevalent, and increasingly available for business Wi-Fi networks.
Marketing for Wi-Fi 7 tends to focus heavily on headline multi-gigabit speeds. But when you’re making a decision on your business Wi-Fi, you need to be thinking about your specific requirements, not just specification numbers.
Will Wi-Fi 7 solve a real problem for your organisation? Maybe, yes. For other businesses, optimising existing Wi-Fi 6/6E infrastructure could provide better return on investment.
What Is Wi-Fi 7?
Wi-Fi 7, also known as IEEE 802.11be, is the successor to Wi-Fi 6/ 6E and is the latest standard in Wi-Fi.
It has been specifically designed for:
- Higher throughput
- Lower latency
- Greater efficiency
- Improved performance in demanding wireless environments
Despite maximum advertised speeds being widely reported, it’s important to remember that these represent theoretical capabilities and are not what every device will experience.
What’s Different About Wi-Fi 7?
The latest Wi-Fi standard has a number of improvements to offer wireless networking, in the right environments.
320 MHz channels
- Up to twice Wi-Fi 6E’s maximum channel width.
- Potentially significantly higher throughput.
- Requires appropriate spectrum and compatible clients.
- Wide channels aren’t automatically the best choice in every business environment.
Multi-Link Operation (MLO)
- Important development for Wi-Fi 7.
- Compatible devices can make use of multiple wireless links/ bands.
- Potential improvements to throughput, latency and resilience.
- Benefits depend upon client/ AP support and implementation.
4K QAM
- More data can potentially be encoded within transmissions. (Higher throughput speeds up heavy tasks)
- Highest gains require very good RF conditions.
- A limitation of this would be that it requires a short range for peak speed. 4K QAM requires a very clean, high-signal environment (high Signal-to-Noise Ratio) meaning that devices generally need to be close to the router to achieve the maximum 12-bit rate..
6 GHz
- Wi-Fi 7 can make use of 6 GHz alongside traditional Wi-Fi bands where regulations/ equipment permit.
- A cleaner spectrum can be extremely useful.
- Higher frequencies also behave differently through walls/ structures.
- UK spectrum availability should be considered when designing
How Much Faster Is Wi-Fi 7?
It’s likely to be faster, but it’s not possible to promise a single set speed. The theoretical specifications of a Wi-Fi 7 compatible AP doesn’t automatically mean that you’ll get that actual throughput on your device.
Real-world Wi-Fi speed depends on multiple factors, including:
- Client capability
- Number of spatial streams
- Channel width
- Distance
- Interference
- Spectrum availability
- Wired uplink
- Internet connection
A Wi-Fi 7 AP connected to a constrained Ethernet network cannot magically provide multi-gigabit end-to-end performance.
Do My Devices Need to Support Wi-Fi 7?
To be able to obtain Wi-Fi 7-specific capabilities, your devices do indeed need to support Wi-Fi 7, yes.
Buying and deploying a new AP will not, unfortunately, turn existing Wi-Fi 5/ 6 devices into Wi-Fi 7 devices.
It often takes a little bit of time to upgrade business client estates – It can be a slow process.
All the equipment that uses the internet needs to be considered – Think laptops, phones, scanners, IoT, printers and specialist equipment.
When you’re looking at upgrading and calculating the value, make sure you assess the expected device refresh needed for that cycle.
Does Wi-Fi 7 Need Faster Ethernet?
If you want your wireless devices to reach their maximum potential speeds, then yes, Wi-Fi 7 needs faster Ethernet ports (such as 2.5Gbps or 10Gbps).
Wi-Fi 7 can theoretically hit multi-gigabit wireless speeds (exceeding 5Gbps to 10Gbps in real-world scenarios), meaning that Ethernet ports can act as a bottleneck. A traditional 1Gbps (Gigabit) Ethernet port can only handle about 940–950 Mbps.
What will happen in real-world terms? If you plug a high-end Wi-Fi 7 router or Access Point into a standard 1Gbps modem or switch, your Wi-Fi speeds will be capped at 1Gbps, wasting the router’s extra power.
Upgrading Ethernet would potentially involve:
- 2.5 GbE/multi-gigabit switching
- Appropriate structured cabling
- Higher PoE requirements
- Switch replacement
- Router/ firewall capacity
- Faster WAN where internet speed is the objective
It’s important, therefore, that Wi-Fi 7 isn’t necessarily considered in isolation of Ethernet.
Will Wi-Fi 7 Improve Coverage?
Wi-Fi 7 does not physically extend the raw range of a single wireless signal, but it can improve overall coverage reliability and efficiency through advanced technologies. Wi-Fi 7 should not be purchased simply on the assumption that it will travel further.
Coverage is heavily governed by:
- Frequency
- Power
- Antennas
- Building construction
- AP location
- Client capabilities
Wi-Fi 7 uses the 6 GHz frequency band (along with 2.4 GHz and 5 GHz). Higher frequencies can offer incredible speeds but have shorter physical range and struggle to penetrate solid walls compared to lower frequencies.
It’s possible that better Wi-Fi design could improve a coverage problem more effectively than upgrading the standard!
Which Businesses Could Benefit from Wi-Fi 7 Now?
There are a number of types of business that could benefit from upgrading to Wi-Fi 7 capabilities. These include:
- High-density offices
- Creative/ media businesses transferring large local files
- Environments with demanding low-latency applications
- Organisations already upgrading switching or cabling
- A new-build or major refurbishment
- Businesses with substantial numbers of new Wi-Fi 7 clients
- Networks being designed for a long replacement lifecycle
- Specialist and high-performance environments
Who Probably Doesn’t Need to Rush to Replace the Network with Wi-Fi 7?
Not all businesses will benefit from running out and replacing their hardware with Wi-Fi 7 capable devices. Businesses that can afford to wait a little while longer before upgrading to Wi-Fi 7 include:
- Small offices primarily using cloud applications/ email
- Businesses where WAN connection is the principal bottleneck
- Predominantly Wi-Fi 5/ 6 client estate
- Networks suffering basic design problems
- Sites with poor AP placement
- Sites with cabling or switching faults
- Businesses who are expecting Wi-Fi 7 alone to fix dead spots
Wi-Fi 6 vs Wi-Fi 6E vs Wi-Fi 7 for Business
| Standard | Key Characteristics |
|---|---|
| Wi-Fi 6 | Mature standard with huge client compatibility; excellent for many businesses. |
| Wi-Fi 6E | Adds 6 GHz capability; serves as a useful stepping stone in compatible environments. |
| Wi-Fi 7 | Offers the newest capabilities and highest performance potential with increasing client availability, though it may require supporting infrastructure investment. |
Remember – The important bit is getting the right technology for your specific business requirements, not automatically upgrading to the newest technology!
Should I Upgrade My Business to Wi-Fi 7?
Before upgrading your business network to Wi-Fi 7, ask yourself these questions:
- What problem are we trying to solve?
- Are our client devices Wi-Fi 7 compatible?
- Can our wired network support Wi-Fi 7?
- Is our existing Wi-Fi properly designed?
If your existing network is unreliable, then upgrading it to Wi-Fi 7 isn’t going to magically fix the problem unfortunately. It’s important to diagnose the cause first.
The best time to upgrade your network is when it provides measurable business benefit rather than just specification-sheet benefit.
