Nowadays, our homes and workplaces are filled with an increasing number of wifi-enabled devices: smartphones, tablets, laptops, smart TVs, smart home devices, security cameras, and even household appliances. A fast, reliable, and well-functioning wifi network is now a basic expectation. However, the traditional router-based wifi system often cannot properly serve these growing demands, especially in larger apartments, multi-story homes, or buildings with thick walls. This is where mesh networks come into play.
But what exactly is a mesh network? How is it different from traditional wifi? What advantages does it offer, and are there any drawbacks? In this article, we will take a detailed look at the technology, how it works, and what you need to know.
How does a traditional wifi network work?
Most home wifi networks consist of a central router to which all devices connect. The router broadcasts the internet signal from the provider in the form of radio waves.
This setup has limitations:
- the further you are from the router, the weaker the signal
- obstacles (walls, furniture, electronic devices) further weaken the signal
- single point of failure: if the router goes down, the entire wifi network goes down
- performance issues: with many connected devices, the router’s bandwidth and performance can degrade
Previously, these problems were addressed with wifi extenders (range extenders), but these often create separate networks (SSID) and provide unstable or slow connections.
What is a mesh network?
A mesh network (also called a mesh wifi network) is a multi-device wireless system where components work together to provide coverage throughout the entire area.
Core components:
- main unit (gateway or primary router) connected to the internet
- additional nodes (satellite units), which communicate with each other and relay data
A mesh network creates one large, seamless wifi network with a single network name (SSID) and consistent coverage.
How does mesh technology work?
- dynamic routing: data packets always travel via the optimal path
- nodes communicate with each other, not just the main router
- if one node fails, the system automatically finds a new path
- users can move freely around the house with their devices, with no need to switch networks manually
How is mesh wifi better than traditional wifi?
1. Uniform coverage
No more dead zones or weak signals in distant corners of the house.
2. Scalability
Easily expandable: just add another node to cover larger areas.
3. Stable connection
The system dynamically optimizes connections, avoiding congested channels.
4. Simple management
Modern mesh systems typically come with a smartphone app for easy:
- setup
- device management
- firmware updates
- network monitoring
5. Single network name
The entire network uses one SSID, so there is no need to switch manually.
When should you choose a mesh network?
- large apartments or homes (over 100-150 m²)
- multi-story properties
- older buildings with thick walls
- if you have many wifi devices
- if uninterrupted online gaming or video streaming is important
What technologies support it?
Today’s mesh systems typically use WiFi 5 (802.11ac) or WiFi 6/6E (802.11ax) standards:
- WiFi 6: higher speeds, better handling of multiple devices
- WiFi 6E: new 6 GHz frequency band with less interference
Which manufacturers offer mesh systems?
- Google Nest Wifi
- Netgear Orbi
- TP-Link Deco
- ASUS ZenWiFi
- Linksys Velop
- Eero (Amazon)
- AVM Fritz!Mesh (popular in Europe)
Are there any downsides to mesh networks?
1. Higher cost
Mesh systems are more expensive than traditional routers.
2. Complexity
While setup has become easier, managing multiple units still requires some attention.
3. Maximum speed
The backhaul connection between nodes (wired or wireless) affects the final speed.
Frequently asked questions about mesh networks
Can you install a mesh system alongside an existing router?
Yes, but it’s advisable to set the existing router to bridge mode to avoid double NAT issues.
Can mesh nodes be connected via ethernet cables?
Yes, this is known as wired backhaul and often results in better performance.
Is it worth replacing an existing wifi extender with a mesh system?
If you want a more stable, reliable connection, then yes.
Future trends in mesh networks
WiFi 7 support
Next-generation WiFi 7 (802.11be) promises even higher speeds and lower latency.
AI-based optimization
Mesh systems that learn and optimize automatically using artificial intelligence.
IoT integration
Mesh networks with built-in smart home hub functionality (e.g. Zigbee, Thread, Matter support).
Mesh for outdoor coverage
More outdoor nodes are being introduced, providing good wifi even in gardens and patios.
A mesh network is an ideal solution if you want consistent, reliable wifi coverage in larger or complex-layout homes. Compared to traditional routers, it is more flexible, scalable, and much more user-friendly.
While it is more expensive, the experience and stability it offers makes it increasingly popular. The future holds even more improvements: WiFi 7, AI optimization, IoT integration — mesh networks are set to become the central element of smart homes.
If you are planning to upgrade or build your wifi network, it is definitely worth considering a mesh system.
