In the event you’re purchasing for a brand new mesh router system, chances are you’ll come throughout references to the platform’s “backhaul.” Right here’s what it’s and the way it impacts Wi-Fi efficiency.
What Is a Backhaul?
The time period backhaul is used throughout the telecommunications business, broadly, to seek advice from the connections between the primary community and the peripheral subnetworks. For example, the hyperlink between your mobile supplier’s most important community and the native tower’s community close to your own home is a backhaul.
Your telephone talks to the native community maintained by the tower after which the gear within the tower communicates over the backhaul again to the primary community. Then the info is transmitted over very high-speed connections like a fiber optic line or a specialised microwave uplink, not the identical kind of connection used between the tower and your telephone.
Very like these backhauls join all of the bigger networks round us just like the mobile community, they will additionally seem inside our house after we use a mesh community platform. And similar to the backhaul improves your expertise whereas utilizing your smartphone by maximizing the transmission velocity between the tower and the larger community, the backhaul in your Wi-Fi mesh router does the identical factor to enhance speeds inside your own home.
The Sorts of Mesh Router Backhauls
In our mobile community instance above we gave two examples of backhauls: one wired (a fiber optic line) and one wi-fi (a microwave uplink.) We used that exact instance as a result of it’s properly fitted to comparability to mesh techniques.
All shopper mesh techniques use one or each of those connection sorts, linking again to the first mesh node both by wi-fi connection over Wi-Fi or by bodily connection over Ethernet cable. Let’s check out the 2 variations of Wi-Fi backhaul you’ll come throughout, Ethernet backhauls, and the way every impacts Wi-Fi efficiency.
Shared Wi-Fi Backhaul
Many mesh techniques, particularly these in additional budget-friendly value ranges, have a shared Wi-Fi backhaul. Usually these techniques are dual-band and solely have a 2.4GHz band and a 5GHz band, so it’s a really secure guess if the mesh system you’re is just dual-band then there’s a shared backhaul.
Mesh techniques that use a shared Wi-Fi backhaul use the only 5GHz band for each fronthaul actions (like your telephone communication with the mesh node) and for backhaul actions (the nodes speaking with one another).

Examples of such techniques embrace Google Nest WiFi, most of the variations within the TP-Hyperlink Deco lineup just like the Deco X20, and the Amazon Eero, Eero 6, and Eero 6+ techniques.
A shared backhaul isn’t the top of the world and there are hundreds upon hundreds of individuals fortunately utilizing the shared Wi-Fi backhaul examples we listed above, however it does affect efficiency. Enhance the variety of purchasers, particularly demanding ones, and also you’ll chew up increasingly more of the shared bandwidth to accommodate them.
Devoted Wi-Fi Backhaul
Once you transfer up from the finances choices and the early-generation mesh techniques, you’ll usually discover devoted mesh techniques with a devoted backhaul.
These mesh techniques have three or extra bands with one band devoted completely to the backhaul communication. The most typical configuration is a tri-band configuration, with one 2.4GHz band and one 5Ghz band for fronthaul use, and one 5GHz band for backhaul use.
The TP-Link Deco X68, a step up within the Deco line, the Netgear Orbi RBK752, in addition to premium choices just like the ASUS Zen Wi-Fi XT8, have devoted wi-fi backhauls that use the additional 5Ghz band.

Some techniques, just like the Amazon Eero Pro 6 have a tri-band configuration however don’t dedicate one 5Ghz band solely to backhaul visitors—backhaul visitors is algorithmically unfold throughout all three bands. That’s not technically a devoted backhaul however the same stage of sources are dedicated to backhaul visitors.
Offloading all of the inter-node communication to the devoted backhaul band frees up everything of the opposite 5Ghz band for fronthaul use—which affords a major efficiency increase for Wi-Fi machine saturated households.
Wired Backhaul
Along with shared and devoted wi-fi backhauls, many mesh techniques help using Ethernet as a devoted high-speed wired backhaul. Usually if the extra nodes, past the system’s base unit, have Ethernet ports that’s a superb signal the system helps an Ethernet backhaul.
Within the case of dual-band (and a few tri-band) techniques, this lets you hyperlink all of the mesh nodes again to the primary node to unlock the whole Wi-Fi bandwidth vary for fronthaul shopper use. It’s extraordinarily helpful for dual-band mesh techniques as a result of it offloads all of the backhaul visitors cluttering up the bands you’re truly utilizing.
Additionally it is helpful for extra superior mesh techniques with devoted Wi-Fi backhauls too. Though chances are you’ll not get the tri-band increase you have been anticipating. Some tri-band routers will launch their additional 5GHz band for fronthaul use when the mesh nodes are related by way of Ethernet which makes every node and the entire mesh community perform like a tri-band router.
However some techniques will at all times reserve their additional 5Ghz band for inside use even within the presence of a wired backhaul. For instance, the tri-band mesh techniques within the Netgear Orbi lineup and the TP-Hyperlink Deco lineup reserve the additional band even when related to Ethernet, whereas nodes within the Linksys Velop lineup will launch the additional band.
Even inside explicit product traces this may change, although, so learn the tremendous print fastidiously when evaluating fashions and don’t assume simply because a selected model of a model’s mesh system releases the additional band all of them do.
No matter whether or not your system releases the band or not, although, you probably have Ethernet out there to attach your mesh nodes, nevertheless, we advocate you achieve this. Gigabit Ethernet ports are an ordinary function today on mesh techniques that help Ethernet backhauls.
And a few superior techniques, just like the Netgear Orbi RBK852, help 2.5 Gbps on the primary unit and gigabit on the nodes, to assist folks with multi-gigabit broadband connections reap the benefits of all that additional bandwidth.
No matter whether or not the system is dual-band with a shared wi-fi backhaul or tri-band with a devoted backhaul, although, you merely can’t beat the stability and speed of Ethernet. You’ll lower latency, improve velocity, and decrease congestion in your community by switching to an Ethernet backhaul.
