Trango Station’s WiFi hotspot enables HD video/audio calling and file sharing in the remotest and highest of places. Its minimalistic hardware (an antenna, a router and a small pi computer) is what sets it apart. No fiber optics, no tower, no sophisticated infrastructure required.
Next Challenge 👉 If this station can connect one village, why not two nearby villages by connecting two wireless hotspots created by trango station. So if two villages can be connected with each other, why not three four or five. Trango Station will make it possible.
Take it for a spin at web.trango.io . (You can also make online Video, Audio Calls. They are P2P, E2E encrypted and serverless.)
What started as an internal experiment at our factory has mushroomed into a passion project for all those involved. After creating a mechanism to make HD Video/Audio Calls and Share Files on the local network (which works well for all sorts of offices, factories and hotels, we decided to move further upstream and think of off-grid uses( (villages, remote areas), where people do not have access to the internet and how they can utilise our backend software. So here’s what we did:
We configured Trango to run on any SBC (Raspberry Pi), then we connected that Pi to a router. This made it a server with routing capabilities. Next we attached a Radio to the router (converts data into signals and vice versa). Finally, we connected an Omni antenna to the radio and created a full blown Wifi Hotspot + Trango Server which is portable in nature and simple to set up.
To our surprise, it worked extremely well when we tested in nearby villages. People were able to make Video, Audio Calls and even share files with each other in a 500 meter distance from the Wifi Hotspot using any smartphone or laptop. We wanted to further push the limits to we tested the Trango Station in a completely off-grid, remote and high altitude area. Our tests were successful there as well. So now we have simple solution using open-source software and off the shelf hardware to connect lets say a whole village. But our next challenge is to connect a neighbouring village with that particular village ( Picture 2). This would mean creating a Bus Network, where every village is connected to each other in a chain. Every Trango Station (Wifi hotspot) would serve as a relay node, enabling all the villages (Trango Stations) to communicate with each other. We have the hardware figured out, (in addition to the omni antenna, a directional antenna will be added).
On the software end, we would need to decentralise the discovery server and its temporary database which allows users to see who else is connected to that particular network. For this, we are looking into distributed databases and ledgers and hope to be achieving a solution soon. Since our project is open-source, anyone is more than welcome to contribute to this.|
