Roof-mounted bonding unit

Every network in reach, one encrypted pipe. On your car roof.

Wan2go is a car roof cargo box with a bonding rig inside. Clamp it onto any roof rack, power it from a 12V socket, and every device in or around the vehicle gets one connection — built from every network the box can reach.

Why one carrier isn't enough

Every carrier has a dead patch on the road you actually need. Every carrier chokes when 30,000 phones turn up at the same finish line. A failover router just moves you from one bad link to the next and kills your sessions on the way over.

Wan2go doesn't pick a winner. It uses every link at the same time, all the time, so losing one costs you capacity. You keep the connection.

03 / Internals

What's going on inside

The router treats every modem, the hotspot link and the Starlink as separate paths, and tracks the latency and loss on each one.

Per-packet split

Traffic is split across paths packet by packet. A big download doesn't get stuck on whichever modem it started on — it pulls from several links at once.

Sliding-window FEC

Repair data rides along with the stream. A modem dropping a few percent of its packets doesn't stall everything behind it — lost packets are rebuilt on the far side without a retransmit.

Sessions bound to the tunnel

When a modem hands over between towers and gets a new address, the session keeps going on the other links. HTTP sessions, file sync, uploads and live video don't notice.

04 / Server

Your server or ours. No subscription lock-in.

A bond has two ends: the box on your car roof and a bonding server out on the internet that puts the traffic back together. You decide where that server runs.

Install it on your own cloud instances or colocated servers you control. Traffic goes out from addresses you own and never passes through anyone else’s network.

Either way, the box works. No subscription ties it to us. Start on our cluster this year and move to your own server next year. Nothing in the hardware cares.

05 / SIMs

Cheap SIMs, any carrier

That's the point of three modems: you don't need one carrier that's good everywhere when three ordinary ones cover each other's gaps. Physical SIM or eSIM, prepaid or contract.

The box finds its modems on its own and reports each one in plain words. When a SIM runs dry, switch it out of the bond from your phone.

One honest catch: in Team internet mode, pulling a link restarts bonding and open connections drop for a few seconds. In Live stream mode the stream keeps going.

06 / More links

Starlink and hotspots

Satellite

The Starlink Mini rides inside the box, out of the weather, and the router bonds it like any other link. Satellite fills the holes where no tower reaches; the cellular modems cover the moments when trees or a bridge block the sky.

Phone hotspot

The second Wi-Fi adapter joins a team member's phone hotspot, picked from a list on the unit page. That's one more carrier, at no extra hardware cost.

07 / Modes

Two jobs, one box

Team internet gives everyone on the Wi-Fi a bonded connection. Live stream hands every link to a camera encoder — plug it in and the router finds it, so you don't type addresses. It's one mode or the other, not both at once.

An admin decides once which mode the box starts in at power-on. After that someone turns the key and it's already doing the right job. The battery keeps it running for 12 hours with the engine off. Nobody calls IT.

08 / Security

Locked down where it counts

Encrypted bond
Traffic between the box and the bonding server is encrypted.
Per-box certificate
A lost or stolen unit gets cut off at the server. Nothing else is affected.
Fails closed
If bonding is off, the router blocks traffic rather than leak it out over a raw modem.
09 / Field use

Where it fits

Command post
At a trailhead with one bar on every network.
Public-order team
Parked along a parade route.
Broadcast crew
At a marathon finish line.
Rally stage
Crew internet between hits, encoder before the cars come through.

Any vehicle with roof bars can carry it. The unit page is built for the person holding the phone in the field.
