What is WiFi 7 & How it Compares to WiFi 5/6?

Understanding Your Home
Network Infrastructure

Before upgrading to WiFi 7, it is helpful to understand the mechanics of your connection. If your internet performance fluctuates when multiple devices are active, the explanation usually lies in how your data is distributed.

Wireless Frequency Bands

💡 Having a 10Gbps fibre plan with an outdated router is like owning a high-performance vehicle restricted to a narrow road. If your router is more than 3 years old, it is likely the bottleneck preventing you from realizing your full plan speeds.

What is WiFi 7?

WiFi 7 (IEEE 802.11be) is the next generation of wireless technology, engineered for Extremely High Throughput (EHT). It fundamentally changes how data is packed and delivered, moving beyond simple speed increases to ensure a significantly lower latency for the most demanding home networks.

What it means for you

How does WiFi 7 work?

WiFi 7 makes 5 specific technical improvements over WiFi 6. Here is what each one does and, more importantly, what you will notice at home because of it.
 

Think of a wireless channel as a road. A wider road lets more cars travel side by side, so more data gets delivered at the same time. WiFi 7 doubles the road width on the 6 GHz band.

• WiFi 6: Channels up to 160 MHz wide.
• WiFi 7: Channels up to 320 MHz wide (Double the capacity).

WiFi encodes data into radio wave patterns. The more data packed into each wave, the faster the delivery. WiFi 7 uses "4K QAM" to increase the data density of every transmission.

• WiFi 6: 1024-QAM (Fits 10 bits of data per signal).
• WiFi 7: 4096-QAM (Fits 12 bits per signal, a 20% increase in peak rate).

Before WiFi 7, devices connected to only one band (2.4, 5, or 6 GHz) at a time. Multi-Link Operation (MLO) allows a device to send and receive data across multiple bands simultaneously.

• Combined Bandwidth: Uses 5 GHz and 6 GHz together to aggregate speed.
• Dynamic Traffic: If one band gets congested, data instantly shifts to the other without a disconnect.

In older WiFi, if any part of a channel had interference (like a neighbor's router), the whole channel became unusable. WiFi 7 "punctures" the interference, keeping the rest of the lane open.

• Efficient Highways: Closes one lane for repairs instead of shutting down the whole highway.
• Singapore Context: Essential for high-density HDBs where dozens of networks overlap.

MU-MIMO determines how many devices your router can talk to at full speed simultaneously. WiFi 6 handles 8 "conversations" at once; WiFi 7 doubles this to 16.

• WiFi 6: 8 spatial streams (Serves 8 devices at once).
• WiFi 7: 16 spatial streams (Serves 16 devices at once).

Who benefits most from WiFi 7?

WiFi 7 makes the biggest impact in these 4 specific home scenarios.
 

WiFi 5 vs WiFi 6 vs WiFi 7

Here is how the 3 generations stack up on the numbers that affect your everyday home use.

On real-world speeds:
The 46 Gbps maximum is a theoretical lab peak. In a Singapore home on a 10Gbps plan, realistic wireless speeds range from 2 Gbps to 4 Gbps for WiFi 7 devices. On a 1Gbps plan, your speed is capped by your subscription. Distance and walls will always affect the final result.

WiFi 6E vs WiFi 7

If you have a WiFi 6E router and are wondering whether upgrading is worth it, this section is for you. The two look similar on paper but are very different in practice.

WiFi 6E adds the 6 GHz band to reduce congestion, but that is where the improvements stop. WiFi 7 introduces technical leaps that are entirely absent from WiFi 6E:

WiFi 7 routers are included with StarHub 3Gbps, 5Gbps, and 10Gbps broadband plans. See current plans.

Should you upgrade to WiFi 7 in Singapore?

With Singapore's dense housing and concrete walls, WiFi 7 hardware is a significant upgrade. Use this guide to see if it’s the right time for your home.
 

WiFi 7 Routers Available with StarHub

StarHub includes a WiFi 7 router free with every broadband plan from 3Gbps and above. The router you get depends on which plan you are on.

Compatibility Note:
Mesh nodes from other brands are not compatible with TP-Link WiFi 7 routers. We strongly recommend using another HB710 or EB810v for the best performance and to prevent signal drops.

Wireless speeds indicated are aggregated wireless bandwidth speeds across all respective bands. Actual performance may vary based on end-device support.

See the full hardware lineup on the 10Gbps routers page and the WiFi 6 and 7 routers page.

Yes. WiFi 7 has a theoretical maximum of 46 Gbps compared to WiFi 6's 9.6 Gbps, which is 4.8 times faster. If you are still on a WiFi 5 router, the gap is even larger: WiFi 7 is 13 times faster. In real-world home use the gap is smaller but meaningful: higher speeds per device, 5 times the network capacity, and 4 times lower latency.

MLO lets a WiFi 7 device connect to two frequency bands simultaneously instead of one. This delivers faster throughput, 4 times lower latency than WiFi 6, and a connection that stays up even when one band gets congested or drops signal. It is the single biggest practical improvement in WiFi 7 for busy households.

WiFi 6E adds the 6 GHz band to WiFi 6. WiFi 7 goes further with 320 MHz channels, 4096-QAM encoding, Multi-Link Operation, and Multi-RU Puncturing. None of those features are available on WiFi 6E. The performance gap between 6E and WiFi 7 is larger than the gap between WiFi 6 and 6E.

Yes, fully. WiFi 7 routers are backward compatible with WiFi 5, WiFi 6, and WiFi 6E devices. Your existing phones, laptops, and smart home devices all connect normally at their existing speeds. They are not slowed down by the WiFi 7 router.

The 46 Gbps maximum requires ideal lab conditions. On a 10Gbps StarHub plan with a WiFi 7 router and a WiFi 7-capable device at close range, wireless speeds of 2 Gbps to 4 Gbps are realistic. On a 1Gbps plan, your wireless speed is capped by the plan speed. Distance from the router, wall construction, and your device's WiFi capability all affect real-world results.

Yes. WiFi 7 routers have been available in Singapore since 2024. StarHub includes WiFi 7 routers free with 3Gbps, 5Gbps, and 10Gbps broadband plans. WiFi 7 client devices including the Samsung Galaxy S24 series and Apple iPhone 16 series are also widely available.

MU-MIMO is how many devices your router can serve at full speed at the same time. WiFi 6 handles 8 simultaneously. WiFi 7 doubles that to 16. In a household with many phones, laptops, smart TVs, and smart home devices all online at once, this means fewer devices get their share without waiting, and speeds stay consistent across the board.

WiFi 8 (IEEE 802.11bn) is in development but consumer hardware is not expected in Singapore until 2028 or later. WiFi 7 hardware is mature, available now, and will remain current for 4 to 5 years. If your router needs replacing, WiFi 7 is the right choice today.
