Every new WiFi generation has promised faster speeds. WiFi 8 breaks that pattern. Codenamed IEEE 802.11bn and designated "Ultra High Reliability" (UHR), the next generation of wireless networking focuses on reliability, stability, and latency reduction â not raw Gbps. When will it arrive, what's actually changing, and why does this matter more for your home than yet another speed bump?

What Changes in WiFi 8
For the first time in WiFi history, the new generation doesn't deliver a noticeable increase in theoretical throughput. WiFi 8 operates on the same bands (2.4, 5, and 6 GHz), with the same 320 MHz channels, 4096-QAM modulation and 8 spatial streams â yielding a theoretical maximum of ~23 Gbps, exactly the same as WiFi 7. The change lies elsewhere.
IEEE 802.11bn sets three core improvement targets compared to WiFi 7:
- 25% throughput increase at a given SINR â meaning better utilization of the same signal
- 25% latency reduction at the 95th percentile â eliminating the stutters in gaming and video calls
- 25% MPDU loss decrease, especially during BSS transitions between access points
This marks a paradigm shift: instead of chasing impressive numbers on spec sheets, WiFi 8 improves what you actually experience â rock-solid stability in every corner of your home, without dropouts. The standard also introduces power-saving enhancements for access points themselves â including mobile APs â and improved peer-to-peer (P2P) operation.
Key Features
Multi-AP Coordination
Multiple access points cooperate in real time through Co-RTWT, Co-SR, Co-BF, and Co-TDMA protocols. Instead of competing for airtime, APs allocate resources in a coordinated fashion, drastically reducing interference.
Seamless Roaming Domain
Transitions between access points become invisible. Context transfer between AP MLDs and per-link transitions ensure your connection never drops â even when moving through a large building or office space.
Enhanced Long Range (ELR)
A new 20 MHz mode using BPSK/QPSK for distant stations. Ideal for IoT sensors in yards, basements, or industrial spaces â delivering signal at distances where today's WiFi vanishes completely.
Next-Gen Quality of Service
HIP EDCA and TXOP Preemption drastically cut long-tail latency. High-priority packets (gaming, video) can preempt the queue, eliminating delay spikes that ruin real-time experiences.

WiFi 7 vs WiFi 8
Comparison Table
| Feature | WiFi 7 | WiFi 8 |
|---|---|---|
| Standard | 802.11be | 802.11bn |
| Designation | Extremely High Throughput | Ultra High Reliability |
| Expected Year | 2025 | 2028 |
| Focus | Speed | Reliability |
| Max Speed | ~23 Gbps | ~23 Gbps |
| QAM | 4096-QAM | 4096-QAM + 4 new MCS |
| Multi-AP Coordination | No | Yes â |
| MLO | Yes â | Yes â (enhanced) |
| Seamless Roaming | Basic | SMD â Full â |
| Enhanced Long Range | No | ELR â |
| IDC (Bluetooth, Zigbee) | No | Yes â |
| Target Applications | Streaming, Gaming | XR/VR, IoT, Telemedicine |
The table makes the philosophical shift crystal clear: WiFi 8 doesn't replace WiFi 7 in speed â it complements it with capabilities that make your connection genuinely reliable, especially in demanding use cases like VR/AR, industrial IoT, and telemedicine.
Under the Hood: The Technology in Depth
Distributed-tone Resource Units (DRUs)
DRUs are one of WiFi 8's most significant innovations. They spread a user's subcarriers across the entire spectrum instead of concentrating them in one contiguous block. This overcomes Power Spectral Density (PSD) limits imposed by regulators â particularly in the 6 GHz band. In practice, this means a stronger signal over longer distances without violating any regulations.
Co-BF: Coordinated Beamforming
With Co-BF, multiple access points steer their beams in a coordinated manner. One AP can create a null toward a neighboring AP's client, effectively zeroing out interference. It's the same principle 5G uses with Massive MIMO, now brought to the world of WiFi.
Beyond these, the 4 new MCS values provide finer rate granularity â delivering a 5-30% rate improvement depending on signal conditions. In-Device Coexistence (IDC) technology tackles a long-standing problem: the clash between WiFi and Bluetooth, Zigbee, or UWB radios within the same device, noticeably improving performance in wearables and IoT hubs.

Timeline & Expectations
Development of 802.11bn began with the formation of an IEEE Study Group in 2021. Here's the journey so far:
- 2021: IEEE Study Group formed
- 2022â2024: Drafts D1 through D4 â core feature and architecture definition
- 2025â2027: Drafts D5 through D7 â technical finalization
- May 2028: Expected final IEEE approval
- September 2028: Final standard publication
However, the Wi-Fi Alliance is expected to begin certification before May 2028, following the same approach it took with WiFi 7. This means the first WiFi 8 routers and access points will ship before the standard is officially ratified. Behind the development are industry heavyweights MediaTek, Qualcomm, Intel, and Broadcom.
Realistically, the first WiFi 8 products are expected to hit the market in late 2028 or early 2029, initially in premium routers and enterprise access points. Mainstream products will follow in 2029â2030, with prices gradually becoming more accessible.
What It Means for Greece
The Greek reality creates unique WiFi challenges: apartment blocks with thick concrete walls, dozens of neighboring networks on every floor, and small flats saturated with interference. This is exactly where WiFi 8's features shine.
Multi-AP Coordination will benefit mesh users (e.g., Cosmote WiFi Booster, TP-Link Deco) â access points in a home will coordinate gracefully instead of competing. Enhanced Long Range will improve connectivity in basements, attics, and balconies without the need for repeaters. Seamless Roaming will solve the classic problem of momentary disconnections when moving from room to room.
Greek ISPs (Cosmote, Nova, Vodafone) will likely begin integrating WiFi 8 into their routers around 2029â2030, following the cycle we saw with WiFi 6 and WiFi 7. Until then, early standalone WiFi 8 routers will be available through import â likely at premium prices, just as the first WiFi 7 models were.
"WiFi 8 doesn't just promise faster internet â it promises internet that doesn't stutter, doesn't drop, and doesn't leave you hanging. For Greek homes with their thick walls and dozens of neighboring networks, that's worth more than any Gbps number."
