Wi-Fi 4, 5, 6 and 7 mainly correspond to n, ac, ax and be; 6E extends ax into 6 GHz. Wi-Fi 8 corresponds to bn, which is still being developed with a focus on reliability. Start with your clients, uses, local spectrum and entire network, rather than comparing numbers on packaging.
Assess generations and bands separately
A generation names technical capabilities; GHz identifies a frequency band; MHz describes channel width. The technical ranges below do not mean every model includes all features, and they are not a list of Hong Kong-approved channels.
First confirm which devices still need this band
Confirm support for sensors, peripherals and older clients by model
Consider channel planning and the usage environment together
Check clients, locations and actual usage before changing bands
Separate technical capabilities from local requirements
For Wi-Fi 6E / 7, check equipment support and the Hong Kong compliance guide
The lines distinguish concepts; they do not represent channel counts, available bandwidth or coverage distance. Confirm operating conditions for the location, equipment and clients
| Generation | IEEE technology | Frequency Bands | Key capabilities | Status and selection |
|---|---|---|---|---|
| Wi-Fi 4 | 802.11n | 2.4GHz／5GHz | Multi-antenna MIMO; 20/40MHz channel widths. | Completed standard; older-client compatibility often needs attention. |
| Wi-Fi 5 | 802.11ac | 5 GHz (ac mode) | Wider channels and 256-QAM; some models support downlink MU-MIMO. | Completed standard; retaining existing equipment can be assessed. |
| Wi-Fi 6 | 802.11ax | 2.4GHz／5GHz | OFDMA, 1024-QAM and TWT; a focus on efficiency with multiple devices. | A completed standard with certified products available. |
| Wi-Fi 6E | 802.11ax extension into 6 GHz | Adds 6 GHz; other bands depend on the model | Extends Wi-Fi 6 technology into 6GHz, providing another set of usable channels. | Products are available; compatible 6 GHz clients and local permission are required. |
| Wi-Fi 7 | 802.11be | 2.4 GHz / 5 GHz / 6 GHz (model-dependent) | Capabilities include MLO, 4096-QAM and channel widths up to 320MHz. | Completed IEEE standard; Wi-Fi CERTIFIED 7 products are available. |
| Wi-Fi 8 | P802.11bn / UHR (draft) | Compatibility with 2.4GHz/5GHz/6GHz remains part of the specification work | Ultra High Reliability: research into latency, packet loss and multi-AP coordination. | The IEEE draft is still under review; vendors have announced development platforms or demonstrations. |

Wi-Fi 4: Ask Before Buying
Confirm bands, security options and update support for the actual model; do not assume all Wi-Fi 4 devices are dual-band.
Wi-Fi 5: A question before buying
A dual-band router usually uses other compatible standards on 2.4GHz; 802.11ac itself does not operate on 2.4GHz.
Wi-Fi 6: a question to ask before buying
Check the functions that the AP and clients can use; OFDMA, scheduling and power-saving benefits depend on implementation and use case.
Wi-Fi 6E: Ask Before Buying
6E is not Wi-Fi 7; replacing an AP does not automatically give older clients 6 GHz capability.
Wi-Fi 7: A question before buying
320MHz requires suitable 6GHz spectrum. Dual-band Wi-Fi 7 models do not necessarily include 6GHz. MLO also depends on clients, operating systems and firmware.
Wi-Fi 8: a question to ask before buying
Do not confuse early hardware, final IEEE approval and Alliance certification; check the exact model, certification and Hong Kong availability individually.
Translate New Features into Uses You Can Validate
Wi-Fi 6
Primarily 2.4 / 5 GHz
Generations describe technical capabilities; names alone cannot determine speed or coverage
Wi-Fi 6E
Adds 6 GHz capability
Check equipment, clients and local spectrum requirements together
Wi-Fi 7
May support 2.4 / 5 / 6 GHz
Actual bands and multi-link capabilities depend on equipment, clients and settings
Band labels indicate technical capabilities only. They do not mean every device supports every band or can operate in any region; see the compliance guide for Hong Kong equipment and operating conditions
MIMO / MU-MIMO: multiple transmission streams
Uses multiple antennas and spatial streams; MU-MIMO can serve multiple clients where supported. More AP antennas do not mean that a single phone can use every stream.
OFDMA: Divide a Channel into Resource Units
Wi-Fi 6 introduced channel-resource allocation across multiple devices. Whether queuing is reduced depends on client support, traffic and scheduling; every device does not receive the same speed multiplier.
TWT: Negotiated wake times
Compatible clients can negotiate active periods, allowing power-saving and scheduling approaches. An AP listing TWT does not guarantee the same battery-life improvement for all devices.
MLO: multiple wireless links
Wi-Fi 7 Multi-Link Operation can arrange transmission across different links. Check the AP, client and implementation mode to determine how links switch or operate simultaneously; this is not the same as failover across multiple internet connections.
320MHz: A Wider Channel
Applicable only to supported 6 GHz deployments permitted locally. Wide channels require sufficient contiguous spectrum; multi-AP sites must also consider channel reuse, rather than always selecting the widest setting.
4096-QAM: Denser modulation
It can carry more data under suitable signal conditions, but does not mean better wall penetration. Measure distant locations and low-signal-quality areas with real client devices.

This is a conceptual checking sequence. Establish a wired or local baseline first, then isolate wireless, upstream and service-layer issues; actual architectures may differ
AX/BE Numbers Are Not Measured Speeds for a Single Client.Before purchasing, check how headline figures are added together, streams per band, port rates, backhaul and client requirements. This page does not present theoretical capabilities as guaranteed Internet download speeds.
Common purchase comparisons today: 6, 6E and 7
This comparison uses verifiable technologies and product options without claiming Hong Kong market-share rankings. Assess whether to retain Wi-Fi 4/5 equipment based on security updates, capacity and actual performance. For Wi-Fi 8, check draft status, certification and availability first.
Wi-Fi 6: compare basic requirements
Start with a list of 2.4/5 GHz clients, simultaneous usage and uplink requirements. If the main clients cannot use a new band, coverage, AP placement and backhaul may deserve priority.
Wi-Fi 6E: Confirm You Can Use 6GHz
Assess the value of 6 GHz only with compatible clients, a suitable room layout and locally permitted spectrum. Intel AX210 product information also requires a compatible AP, operating system and local approval.
Wi-Fi 7: Assess features and infrastructure together
Assess MLO, 6GHz, switches, PoE, port speeds and management costs. The official BE200 specifications demonstrate that Wi-Fi 7 clients exist; they do not mean every computer or AP supports the same capabilities.
Deployment trends: interpret only the known sample
Cisco's 2026 report records a 23% increase in Wi-Fi 6E/7 AP deployments in its network sample during the second half of 2025. This is growth within the supplier's own sample, not Hong Kong market share or a reason for every customer to upgrade.

These selection guidelines were prepared by WiFi-HK. Supplier information supports product details or published samples only; it does not indicate brand partnerships, endorsements or a survey of the entire market.
Wi-Fi 8: Standards, certification and products are separate matters
01 · IEEE Draft
In September 2026, TGbn was still addressing D2.0 ballot comments and producing D2.1. The official schedule's final approval milestone remains a projected 2028 event; the standard is not complete.
02 · Model-specific certification
IEEE standards development is separate from Wi-Fi Alliance product interoperability testing. Check the model, hardware/firmware and listed features before purchase. This page has not verified a particular Wi-Fi CERTIFIED 8 product and does not claim that full certification has been achieved.
03 · Vendor announcements or demonstrations
TP-Link has announced the Archer 8 platform and planned availability; ASUS ROG NeoCore is a draft-based concept demonstration. These announcements alone do not establish Hong Kong availability, local compliance or formal certification.
Development Focus: Completing Work More Reliably
UHR means Ultra High Reliability. Research includes improving latency, packet loss and multi-AP coordination; draft objectives or vendor test results are not this website's improvement commitments for customer sites.

Before trialling an early product, obtain written details of features, update plans, compatibility and fallback arrangements, and test representative clients; an operational business need not replace its entire network based only on a new generation name.
How Do You Choose for Each Environment?
| Environment | What to Check First | Selection direction | How to validate |
|---|---|---|---|
| Home / Small Studio | Rooms, walls, client models, broadband and wired backhaul | Compare actual needs across Wi-Fi 6/6E/7; first confirm 6 GHz clients and permitted spectrum | Use your usual phone or computer to test the local network, video applications and internet access room by room, rather than testing only beside the AP |
| Offices / meeting rooms | Busy-period device counts, meeting applications, and guest and employee permissions | Choose around capacity, AP placement, channel reuse and uplinks; validate 6E/7 where new features are needed | Concurrent use of specified applications; check roaming, authentication and guest separation |
| Warehouses / Scanners | Scanner bands, shelf heights, materials in a fully stocked warehouse and movement routes | Prioritise client compatibility and coverage along work routes; a newer AP generation cannot give older scanners new capabilities automatically | Walk routes with the actual operational clients, testing the scanning application, reconnection and full-stock conditions |
| Hotels / Retail / Schools | Peak periods, guest access, operational devices, permissions and management policies | Beyond the generation, assess separation, centralised management, maintenance and licensing responsibilities | Validate specified rooms or areas, concurrent connections, access restrictions and management handover |
These are engineering planning guidelines, not automatic equipment recommendations or universal acceptance thresholds. Distinguish coverage, capacity, interference, uplink and application bottlenecks before discussing equipment and budgets.
Hong Kong procurement: Check 6 GHz requirements before the generation
Hong Kong does not prohibit all 6GHz use. HKCA 1081 Issue 2 specifies an operating range of 5.945–6.425GHz, with 5.925–5.945 GHz as a guard band. Indoor and outdoor power limits and LPI / VLP class requirements also apply. Check model verification, CA labelling, service arrangements and related matters against current requirements.

A 6E/7/8 Label Does Not Permit Every Overseas Channel in Hong Kong.Changing the region menu alone does not establish compliance; Wi-Fi 8 research news does not automatically change Hong Kong spectrum rules. Request the local equipment version and compliance information before purchasing.
Common questions
What do Wi-Fi 4, 5, 6, 7 and 8 correspond to?
The generation names generally correspond to 802.11n, 802.11ac, 802.11ax, 802.11be and the developing P802.11bn, respectively. Wi-Fi 6E extends Wi-Fi 6 technology into 6GHz; it is not a separate seventh generation.
Which generation is most commonly used now?
Distinguish global shipments, enterprise deployments, Hong Kong homes and your own devices first. This page does not contain a Hong Kong market-share survey; official certified-product and deployment information can inform comparisons of Wi-Fi 6/6E/7, but a single supplier's sample cannot establish a market-wide leader. Start with clients, applications and uplinks.
Has Wi-Fi 8 Been Finalised or Fully Certified Yet?
As checked for this page on 11 October 2026, IEEE 802.11bn remains under draft review. Vendor platforms or concept demonstrations do not constitute a final IEEE standard or Alliance certification for a particular model. Request current model details, certification, local compliance and confirmed availability before procurement.
Does Wi-Fi 7 always include 6 GHz and 320 MHz?
No. Products may support different bands and features; 320MHz needs suitable 6GHz spectrum. APs, clients, operating systems, firmware and local regulations must support it. The Wi-Fi 7 name alone is not enough.
Are Wi-Fi 6E, 6 GHz and 6G the same thing?
No. 6E extends Wi-Fi 6 into the 6 GHz band; 6 GHz is a frequency band, while 6G usually refers to sixth-generation mobile communications. Specify the technology generation, bands and model separately when selecting equipment.
Can 6GHz Be Used in Hong Kong?
Equipment meeting Hong Kong requirements can use the specified lower band. HKCA 1081 lists 5.945–6.425 GHz as the operating range, with 5.925–5.945 GHz as a guard band. Check equipment class, power, verification and labelling requirements together; do not copy overseas settings.
Will upgrading to a newer Wi-Fi generation resolve all slowness and disconnections?
No. Walls, AP locations, busy channels, backhaul, PoE, the internet connection, clients and applications can all be bottlenecks. Establish a wired baseline and measure the problem before replacing equipment or changing the design.
Sources and Verification
This page checked the following primary sources on 11 October 2026. IEEE documents describe standards progress; a certificate covers the tested features of that model only; vendor pages support only their products and published information.
