Physical AI can’t afford a dropout.
A three-second connection loss can stall a robot mid-task, break a teleoperation session, or force an autonomous vehicle into a safe stop.Connectify builds Speedify, packet-level channel bonding that combines Wi-Fi, 4G/5G cellular, Ethernet, Starlink and satellite into one connection, with load balancing and failover built in. Traffic is spread across every link packet by packet, so when one fails, the session keeps running with no reset or reconnect. The Speedify SDK builds the same technology directly into robots, vehicle platforms and edge devices running Linux, Android or QNX.

How Speedify Works
Speedify bonds at the packet level, so one link can drop without dropping the session.
Speedify splits traffic across every active connection at the same time. A single video call, file upload, or teleoperation stream uses the combined bandwidth of all links instead of being pinned to one.
When a connection fails, Speedify keeps sending packets over the links that remain. The session continues without a reset, a reconnect, or a new login.
Failover and load balancing work differently. Failover waits for the primary link to be declared down and then switches, which resets active sessions. Load balancing spreads separate sessions across links, so any session on the failed link still drops.
How Speedify Compares
Speedify compared with other multi-link approaches
| Approach | When one link fails | Can one session use every link? | Where it runs |
|---|---|---|---|
| SpeedifySoftware channel bonding | Session continues on the remaining links | Yes, packet by packet | Windows, macOS, Linux, iOS, Android, OpenWrt routers, and embedded on Linux and QNX via the Speedify SDK |
| Dual-WAN failoverMost business routers | Switches to the backup after the primary is detected as down; active sessions reset | No, one link at a time | Router or firewall |
| Per-session load balancingSpreads separate sessions across links | Sessions on the failed link drop; others continue | No, each session stays on one link | Router or firewall |
| Cellular routers and appliancese.g. Peplink, Cradlepoint | Varies by model and license | On models and licenses that include bonding | Vendor hardware |
| Broadcast bonding unitse.g. LiveU, Dejero | Built to keep video contribution live | Yes, for video contribution | Dedicated field units and receivers |
| SD-WANPolicy-based path selection | Steers traffic to healthy links; speed varies by vendor | Usually per flow; some vendors offer packet duplication | Branch appliances or virtual edges |

What Speedify does
What Speedify does for mission-critical connections
Packet-level channel bonding
Speedify uses up to 95% of the combined throughput of every connected link, for one session or many.
Automatic failover
Speedify reroutes traffic to the remaining links in milliseconds. Calls, uploads, and streams continue without a session reset.
Streaming QoS
Speedify detects video and voice traffic and prioritizes it over background traffic on Teams, Zoom, OBS, and any RTMP or WebRTC platform.
Redundant mode
Speedify sends every packet over every link, so a packet lost on one connection still arrives over another. Built for the moments when latency matters more than data usage.
Deployment
Speedify deployment options
Where Speedify installs and where Speedify routes to are separate decisions. Most enterprise customers combine more than one.
On devices
The Speedify app runs on Windows, macOS, Linux, iOS, and Android. Speedify Teams adds central billing, user provisioning, usage analytics, CSV import and export, and a RESTful management API.
On routers
Embedded connection-bonding for router manufacturers, networking appliance builders, and smart device makers — license the same technology behind Speedify as an SDK for your hardware.
Inside robots, vehicles, and products
The Speedify SDK embeds channel bonding in iOS, Android, Windows, macOS, Linux, and QNX products: carrier offerings, vehicle platforms, robotics, routers, appliances, and smart devices. Speedify Custom Engineering can build the integration for you.
QNX software runs in more than 275 million vehicles, according to Counterpoint Research figures published by QNX in December 2025.
Where Speedify runs in production
Physical AI
Teleoperation video, telemetry, and fleet updates for AMRs, humanoids, drones, and autonomous vehicles, with the Speedify embedded daemon running natively on Linux and QNX.
Starlink
Speedify bonds multiple Starlink dishes with cellular and wired links so sessions survive obstructions, satellite handoffs, and weather.
Maritime
Whole-vessel bonded networks for commercial fishing, workboats, charter yachts, and offshore platforms.
Live Broadcast
Field, sports, and breaking-news production that stays on air, working alongside existing broadcast gear.
QNX software runs in more than 275 million vehicles, according to Counterpoint Research figures published by QNX in December 2025.
