सेतुbridge — Resilient Mesh Communications
What if the tower went down and the satellite was jammed — could your team still stay in touch?
Normal communications have one weak point; knock it out and everyone goes silent.
The situation
An operation after the network is gone
There is no central network left. Each radio quietly passes messages along for the others, so voices, data and everyone's position keep moving. Knock out one radio and the message just takes another route — nobody drops off the map.
How it plays out
Step by step
- 01
The centre is gone
Towers and satellites are down or jammed — the usual weak points.
- 02
Every radio helps
Each one carries messages for its neighbours, forming a web with no single centre.
- 03
One is lost
A radio is knocked out — and the network instantly finds another way around.
- 04
The team stays linked
Voices, data and everyone's position keep working through the damage.
The system itself
Under the bonnet
Every node relays for every other and routes around damage automatically, so a network with no centre carries voice, data and position-tracking even as nodes are lost. It rides on top of tactical radios already in service.
What it means for you
The bottom line
- ▸No single weak point to attack
- ▸Fixes itself around losses
- ▸Carries voice, data and positions
- ▸Works with the radios you already have
