Improve Your Home WiFi Coverage with a Mesh Network System

In this ever-evolving world, there have been numerous technological advancements that make our lives easier.

Look no further than the internet. Gone are the days that we had to spend hours poring through libraries or phone books to gain information – the Dewey Decimal System has only a few die-hard adherents, and entire generations don’t even know how to use it.

However, as much as the internet and wireless internet have helped life become simpler, it’s not perfect. If we had strong, reliable internet EVERYWHERE we go, then maybe. Some of us don’t even have it at home. Many of us pay for high-quality internet, but often, it doesn’t cover every single room.

If you struggle with covering your whole home with WiFi signal, you may have heard of a mesh network system or mesh WiFi system. In recent years, mesh systems have been deemed the most effective and efficient solution for improving your home WiFi coverage.

What is a Mesh Network?

Mesh networking is the newest form of wireless internet. A mesh network is designed to blanket your entire home with WiFi coverage. A WiFi mesh network is a system composed of multiple mesh nodes (commonly referred to as points, mesh extenders, or satellites) that work together as one large home WiFi system.


How Do WiFi Mesh Networks Work?

How Do Mesh Networks Work?

WiFi mesh networks use multiple nodes that communicate with each other to share a wireless connection within a larger area. One node acts as your main mesh WiFi router. It’s connected directly to your internet modem or wireless gateway (a combination of a wireless router and a modem). A modem is a device that accesses the internet. When routers or switches are connected to the modem, they are able to tap into the internet and broadcast it to give your connected devices WiFi access. In addition to the main node, you will have additional nodes that will need to be set up around your home to improve the WiFi signal and eliminate dead spots.

The amazing thing about mesh networks is that they are truly wireless!

The node connected to the modem wirelessly shares its internet connection with all the other nodes within its range. Those nodes wirelessly share their internet connection with the nodes within their range. It’s almost like having multiple WiFi routers in your home, but they share one seamless WiFi network. As a result, having multiple nodes increases the wireless internet coverage throughout your home.

Nodes are built with smart technology that tells them how to communicate within the large wireless network. Information travels from point A to point B by jumping from one node to the next. They use adaptive routing or dynamic routing technology to automatically choose the fastest and safest route to send and receive information. For example, if one node was to stop working, the whole system will adapt to the change and automatically re-route the information through a different path. In addition, if one node has many devices connected to it, the system will register the congesting and will automatically re-route all of the information to jump through a different path to avoid speed slowdowns.

As you can see, the whole system works together to provide you with the best coverage and the fastest speeds available. Unlike traditional WiFi, mesh systems do not rely on one single point of communication between the main router and the wireless devices to send and receive information.


How Do Wired Mesh WiFi Networks Work?

If your home is already wired with ethernet cables, or if you want to use a wired connection, you can. Make sure your nodes are ethernet backhaul compatible. Ethernet backhaul is a fancy way of saying that the backbone of the network is composed of a wired connection rather than a wireless connection. If the nodes are compatible, they’ll have ethernet ports for a successful wired installation.

The nodes will be wired to a switch, and the switch will be wired to the LAN port of the mesh WiFi router (node connected to the modem for internet access). The main node will pick up on the wired connection and transmit information through fast ethernet cables or gigabit ethernet cables.

There are some benefits to a wired installation. Any wireless form of communication is susceptible to speed slowdowns due to obstacles like walls, floors, doors, and building material; however, some are affected more than others. When using cables, you bypass all obstacles, resulting in faster speeds throughout the entire home.


How to Install a Mesh Network

Mesh systems can be installed in minutes, you don’t need to have extensive technical knowledge. There are a variety of different mesh network models (Amazon Eero, Linksys Velop, Netgear Orbi, Tp-Link Deco m5, Netgear Nighthawk, Google Nest WiFi, etc.) and each one has a different setup process, but with similar details.

Here is what a general installation process looks like:

  1. Most systems require you to download a mobile app that will walk you through an easy setup process. It will provide you with easy to follow instructions.

  2. After downloading the app, log into the account, or create a new one if you don’t have one.

  3. Before connecting the devices, it’s recommended to unplug your modem or wireless gateway. Use an ethernet cable to connect the modem to the WAN port of the main node. After they’ve been connected, reconnect your modem and let the devices power up.

  4. Using the app, follow the instructions provided to connect the main node to the modem. You will be asked to enter the location of where the main node will be setup. In addition, you will need to create a network name for the system (SSID).

  5. Once the main node has been connected, use your smartphone, laptop, or tablet to open the WiFi settings. Look for the mesh network name you created and connect to it.

  6. After the main node is successfully connected, more nodes can be added. With each additional node, you will have to enter the location in which they will be placed. The placement of the nodes is very important. It’s recommended to place the nodes halfway between the main node and the dead zones. Nodes need to be connected to a power supply, so make sure there is a power outlet nearby. If you are unsure of where to place the nodes, there are some apps that will help you find the best location for them. Also, some nodes have an LED light that inform you if they are too far from another node.

What are the Benefits of Having a Mesh Network?

Simple Setup and Ease of Use

Most mesh networks come with user-friendly apps that assist you in the installation process and allow you to monitor the system. You are able to scan the speed, create guest networks, test the quality between connection points, remove users from the network, add parental controls, and more.

Seamless Connection

As mentioned, mesh networks are one large WiFi system. Even though it has multiple nodes, the system only has one network name and one password. Your wireless devices will automatically connect to the closest node within the single network without having to manually change network connections.

Flexible and Expandable

It's extremely easy to add extra nodes to expand the coverage into those hard to reach areas for a reliable WiFi connection. If needed, you can also easily remove or rearrange the nodes.

Adaptive Technology

With smart technology, if you need to add, remove, or rearrange nodes, the system will automatically configure itself to find the best routes to send and receive information. In addition, if a node stop working, the system will configure itself to register the change and re-route all of the information to jump through a different path.

Aesthetic Design

Many who have traditional routers or extenders hide them because they are not pleasing to the eye. Mesh networks are small and designed to match your home decor. You won’t have to tuck them away in a closet, a drawer, or behind furniture. To make mesh nodes more appealing to the eye, some models feature smart speakers powered by virtual assistant technology like Google Assistant and Alexa.

Secure

Mesh systems use WPA2 or WPA3 privacy encryptions; these are the most secure encryptions available. WPA3 is an improved version on WPA2. It helps make public WiFi networks safer and makes it harder for hackers to access your private network. If hackers were to access the network, they will only be able to see a limited amount of information.


What are the Drawbacks of a Mesh Network?

The main drawback of mesh networks is that they can be pricey. A good quality mesh kit can cost $200 or more. The kits do include 2-3 nodes, but for those who need additional equipment will need to purchase extra nodes separately. Depending on the brand of the kit, additional nodes can range between $100-$200.


How to Choose the Best WiFi Mesh Network?

There are a lot of different mesh network manufacturers (Amazon, Linksys, Samsung, Asus, Google WiFi, D-Link, etc.), each with different pros and cons. To figure out which would be the best mesh WiFi system, you will need to understand some terminology.

Wireless technology communicates between devices through sound frequencies. The two frequency bands used are 2.4GHz and 5GHz. The difference between the two bands is speed, range, and bandwidth. The 2.4 GHz band can travel further with slower speeds. In contrast, the 5GHz band provides high-speeds but it doesn't travel as far.

All WiFi mesh systems use both frequency bands, and many are tri-band (use one 2.4GHz band and two 5GHz bands). The second 5GHz band is often designed to communicate between the mesh router and the nodes, which can increase WiFi speeds throughout your home. Most of the time, the system will automatically choose the clearest frequency to connect to the internet and your wireless devices. There are some systems that will allow you to choose between bands. If you have smart home devices that require a specific band, make sure the mesh kit you choose allows you to modify the frequency.

Mesh systems have to follow the 802.11 WiFi protocols. The best mesh systems you will find are the ones that fall under the 802.11ac (WiFi 5) and 802.11ax (WiFi 6) protocols. WiFi 6 is still relatively new, it’s supposed to increase throughput speeds, have less network congestion, and provide better range performance. In addition, they have improved MU-MIMO (multi-user, multiple-input, multiple-output) technology, meaning more devices can be connected to the network simultaneously without hindering the internet speed.


What are the Best Mesh Networks for My Needs?

First, understand that different systems target different needs.

Are you just looking to get rid of dead spots? Do you want to extend your coverage outside? Do you need a mesh system to improve your gaming experience?

If you just want to get rid of all the dead spots and extend your WiFi coverage, tri-band mesh systems are great for whole-home coverage. If you are a gamer or someone in your family is a gamer, there are specific mesh systems available for gamers, like the AmpliFi Gamer Edition by Ubiquiti. They are designed to provide optimal speeds and prevent gaming latency.

Regardless of which brand you go with, always check the specs. Look at the square footage they support, the 802.11 standard they use, the bandwidth, and the frequency bands.


How Many Nodes are Needed for Whole-Home Coverage?

Most mesh kits include 2-3 nodes, one will be connected to the modem and the others will be placed around your home. Essentially, you can have numerous nodes; some mesh systems support up to 32 nodes.

Before you go and spend all your hard-earned money on 32 nodes, figure out how much coverage you’ll need. To do that, figure out the square footage of your home, including outdoor areas that you want to cover AND factor in the distance between floors for multi-story homes. The range of each mesh system varies between models. Make sure to check the specs on the systems that interest you; some nodes provide more square feet of coverage than others.


Difference Between Mesh Networks and WiFi Extenders

Mesh networks and WiFi extenders both extend the WiFi coverage, but they are very different from each other.

WiFi Range and Speed

WiFi extenders are great for patching up dead spots, but their speed and range are easily affected by obstacles like walls, furniture, doors, and floors. The devices connected to the extender probably won't experience the fast speeds you might expect in every corner of your home, especially if you have a large home. Mesh systems are much better at covering a larger area with the least amount of speed slowdowns. The use of multiple access points helps the signal travel smoother throughout the entire home and is not as easily disturbed by obstacles.

Network Connectivity

Extenders broadcast their own signal, meaning that they have their own network name and password. You will manually have to change between your home network and the extender as you move around your home. Mesh networks provide a seamless connection. You are able to roam around your house without having to worry about changing the network name; your device will change automatically between the closest nodes.

Band Technology

Most extenders use dual-band technology, meaning they can send data through one band and receive data through the other. If there is a lot of traffic or interference through one band, you will start noticing speed slowdowns. Most mesh networks use tri-band WiFi technology that adjust automatically for optimal speed.


Do I Need a Mesh Network?

Mesh networks are a great solution for eliminating poor internet connections in those hard to reach areas, like the basement, backyard, garage, etc. However, they are not the best solution for every situation.

If you have a large home that is 3,000 sq ft or more, a home with building material obstructions (metal walls and brick walls), or a multistory home, you will benefit from a wireless mesh network. The multiple nodes will help expand the coverage into every room for a whole-home WiFi coverage and reduce the interference caused by obstacles.

On the other hand, if you live in an apartment or a small home, and only experience dead zones or poor speeds occasionally, you might not need a mesh network. A range extender will work just as well and will be a more cost-effective solution that can help patch up the problem area.
