"Should I choose latex paint or art paint for wall painting?" " You can change it after checking in, but "WiFi6 or WiFi7?" Once the wrong network cable is buried or the wrong route is selected, the cost of upgrading later will double! This article will guide you step by step on how to choose the right home network solution for the next five years, from technology to scenarios.
Technical Analysis: One Generation Behind, What's the Difference?
The core differences between WiFi6 (802.11ax) and WiFi7 (802.11be) lie in three points:
Speed leap: The maximum speed of WiFi6 is 9.6Gbps, while WiFi7, through a 320MHz bandwidth and 4K-QAM modulation, has a theoretical speed soaring to 46Gbps (approximately 15-20 GBPS in actual home scenarios).
Frequency band expansion: WiFi7 has added a 6GHz frequency band (5925-7125MHz) to avoid congestion caused by 2.4G/5G, similar to "adding a dedicated lane to a highway".
Anti-interference upgrade: Multi-link aggregation (MLO) enables devices to simultaneously connect to the 2.4G/5G/6G frequency bands, enhancing signal stability by 30% in complex environments.
Scene decision tree: Match the requirements accordingly
When choosing WiFi6 is sufficient
Unit size: ≤120 square meters, wall size: ≤3 blocks (single route coverage for no worries)
No more than 30 connected devices (mainly mobile phones, tablets and smart speakers)
Main requirements: 4K video streaming, regular mobile games, smart home control
Suggested scenarios for WiFi7:
Unit type ≥150 square meters or duplex/villa (Mesh networking is required)
At least 50 networked devices (including 4K projectors, game consoles, cameras, etc.)
Core requirements: 8K cloud gaming, VR/AR devices, low-latency remote working
Hidden costs: Don't let your wallet "stab you in the back"
Device compatibility: If your current mobile phone or computer only supports WiFi6, upgrading the router is like "a small horse pulling a big cart". It is recommended to wait until WiFi7 devices become widespread in 2026 before making the switch.
Pre-buried network cables: If the 6GHz frequency band is planned to be deployed, super Category 6 / Category 7 network cables need to be buried at key positions during decoration (with an increase of 5-10 yuan per meter in cost).
Mesh networking: For large-sized apartments, when choosing WiFi7, it is recommended to pair it with Mesh nodes of the same brand (such as ASUS AX11000+ two XT12s), as the cost is 30% to 50% higher than that of a single router solution.
Selection tip: Three looks and two don't touch
Look at the apartment type: For small-sized apartments, choose WiFi6+ single router; for large apartments or villas, directly choose WiFi7+Mesh
Check the equipment: There are many 8K projectors /VR devices →WiFi7; Ordinary audio-visual games →WiFi6
Check the budget: Within 2,000 yuan, choose a WiFi6 flagship (such as TP-Link XE75), and for 3,000 yuan +, directly choose WiFi7 (such as Xiaomi 10G Router).
Avoid "castrated versions" : Be cautious of "WiFi7 routers" under 1,000 yuan, which are actually soft upgrades to WiFi6+6GHz frequency bands
Don't blindly follow the new: In 2025, the mainstream devices will still be dominated by WiFi6. Non-geeks can wait until 2027 to upgrade
WiFi6 is an "economical car", while WiFi7 is a "performance supercar" - choose the right one, not the expensive one. A good network is one that suits your own needs. The next time you give the water and electricity briefing, remember to leave 10 minutes for the network plan: After all, the house can be installed gradually, but once you move in, a lagging network is hard to fix!
