Link Aggregation and Mobile Data Offloading Made Easy
Channel bonding combines two or more internet connections into one, spreading your traffic across all of them at the packet level for faster speeds and staying online if one drops. Unlike basic round-robin bonding, smart bonding measures each connection and sends traffic where it flows best.
Speedify is an app that uses this channel bonding to combine Wi-Fi, 4G/5G, DSL and wired connections for faster upload and download speeds plus seamless failover. Here is how channel bonding works.
<1 sec
With Speedify, your internet stays on when one connection fails.
When one of your internet connections drops, Speedify shifts your traffic to your remaining connections in under a second — so calls don’t cut out and downloads don’t stall.
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.
4G/5G cellular
Works anywhere. Just a SIM or hotspot — no installation needed.

Best for fixed locations. Different network, so outages rarely overlap.

Adds redundancy and throughput for remote sites or heavy usage.

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.
