A guide to mesh networks

Published: 09th July, 2021 at 13:02

What is a mesh network, and how can it help you improve your home's Wi-Fi connection?

You’ve got speakers talking to lights, doorbells wirelessly hooked up to your TV and security cameras firing feeds to your phone. With all that smart home action in play, it’s the wise move to think about whether you’ve created the best environment for all that smart kit to go about its business without connectivity problems.


That’s where mesh networks can come to the rescue. If you have no idea what a mesh network is, why you need one or how to set one up, we’ll take you through the key nitty gritty details of all things mesh and why it’s good to have one supporting your dream of a smart home.

What are mesh networks?

Mesh networks are all to do with connectivity, specifically, the Wi-Fi kind. It’s essentially the idea of putting multiple Wi-Fi points in a space like your home instead of just the single one. Most homes rely on a single Wi-Fi router to spread that data around to different devices that need it.

Those multiple Wi-Fi points in a mesh network can communicate wirelessly with each other to create one big Wi-Fi blanket that your connected devices can all tap into. The devices that can create those points are known as mesh systems, which are made up of multiple units that you place around your home.

How do they work?

Whether you buy a mesh network setup independently or through your internet provider, these systems will either plug directly into your router or modem. The hub device will then communicate with a satellite device placed in another part of the house, which will extend the reach of your Wi-Fi network. You might, for example, connect your mesh network to your router in the living room, and then place a second piece of kit in the kitchen where it can stretch your Wi-Fi coverage out over the garden.

Once they’re chained together, they’ll create that single network where the same password is used for all points in the setup. Systems tend to come in threes, but don't overdo it. If chaining two devices gives you the Wi-Fi coverage you need, it’ll provide the most efficient system for sending your data around the house.

Why do you need one?

The big reason you’d want one is if you have lots of devices spread across your home that require Wi-Fi to function, fighting to use a single Wi-Fi network. It can notably improve Wi-Fi coverage for areas a single router might be struggling to reach. It's a better option than a Wi-Fi extender, since a Mesh network will allow you to walk around your whole house & garden and stay connected - it's a seamless connection, you won't need to switch from one network to another.

In other words, it can wipe out any Wi-Fi deadzones your house might have. It can also reduce the chances of suffering connection dropouts. If there is a drop out at one point in the network, your device can start talking to another point in the system to keep things running. It’s a strong option to get set up in your home if you’ve got a lot of connected kit in play at all times.

How do you set up a mesh network?

You know the benefits, you know how it works, so how do you arrange your mesh Wi-Fi network to get that desired result of improving coverage for all of your devices? Placement is key here, particularly as most setups need to be situated in close proximity to plug points to bring those mesh networks to life.

You’ll want the additional modules positioned in open spaces away from other objects that might interfere and block the created Wi-Fi signal. If you’re planning to improve coverage outside of your home, you can opt for weatherproof systems if you want to get a good connection to smart outdoor speakers and lights, for example.
