What Is Channel Bonding and How Does Speedify’s Channel Bonding Technology Work?

Link Aggregation and Mobile Data Offloading Made Easy

Speedify’s unique channel bonding technology lets you spread your Internet traffic across all of your Mac, PC, Android or iOS devices’s available Internet connections using our worldwide network of servers in the cloud. With Speedify, you’ll enjoy faster and more reliable Internet using all available Wi-Fi, 4G or 5G, DSL and other wired connections to speed up HD video streaming, uploads, and everything else you do online.

Most channel bonding solutions aren’t intelligent and just blindly pass packets out over each network connection in a “round robin” fashion, like dealing cards in a card game. This approach is only beneficial when you have connections that are identical in performance, like two matched DSL lines. Using the round robin channel bonding approach with connections of varying capabilities limits the maximum possible combined performance drastically. However, Speedify’s smart channel bonding technology is capable of detecting the capabilities of each network connection and intelligently distributing the traffic so that you can maximize all connections up to 95% efficiency of their combined throughput.

Quick answer

Should you have a backup 4G, 5G, Starlink, or cable internet connection?

Yes — every internet connection goes down, including Starlink, which drops for ~34 minutes a day on average. A backup connection from a different provider means one outage never takes you fully offline. The most common options are a 4G/5G cellular hotspot, a cable or DSL line, or a second satellite dish.

Speedify bonds any two connections into one — automatic failover, more speed, no dropped calls.

Flawless Failover

But, channel bonding isn’t just about speed. Speedify can also make your network more reliable. Through the magic of channel bonding, you can stay online as long as one of your networks remains connected. Speedify offers seamless failover between multiple connections so even if you step out of the range of your wifi router your Skype call won’t be dropped, your file upload won’t have to be restarted, and your streaming video keeps going without skipping a beat.

Bandwidth Everywhere

These days, we’ve got access to more Internet connections than ever before. No matter where you are, it’s likely that you can get onto a free WiFi network, and just about everyone has a mobile hotspot or tethered 4G connection, too. However, more often than not, any single public or mobile broadband connection won’t offer you the bandwidth necessary for daily online activities like streaming HD video content on YouTube and Vimeo. But, with more users combining their available Internet connections with Speedify’s easy channel bonding service, we hope to make endless video buffering and slow uploads a thing of the past.
