Your range is your Crew
One phone's Bluetooth only reaches so far. But every phone running 1Bar can pass your message on, so the reach grows with the people carrying it.
One phone reaches only so far
Bluetooth covers a limited distance. Trees, rock and walls cut it. On its own, one phone cannot reach someone on the far side of a hill.
Phone to phone to phone
Each Crew member's phone can pass your message along. A Crew spread out along a trail forms a chain, so a message can reach the far end even when the first and last person cannot see each other. More people means a longer chain: the Crew itself becomes the antenna.
People carry messages
If someone is out of reach, the message waits on the phones nearby and travels with whoever walks toward them. It arrives when they meet. In quiet places that can take minutes or longer, not seconds. Text messages are kept for 24 hours, and SOS cards for 48.
More people, more reach
Every phone running 1Bar can help carry everyone's messages, encrypted so it cannot read them. In a crowded place there are many phones, so there are many paths. Each new person adds paths for everyone already there.
Illustrations only, not to scale.
The more people, the better it gets
The value of a network grows with the number of connections people can make, so each new person makes 1Bar better for everyone nearby.
What to expect
How quickly a message arrives depends on how many people are around. In a crowded place there are many paths and delivery can be quick. In a quiet place it can take minutes or longer, and a message may not arrive at all.
- Bluetooth range is limited, and a message may take time to arrive, or may not arrive.
- In sparse places, delivery depends on people moving past each other.
- Everyone in a Crew needs 1Bar.
- An SOS card alerts your Crew. It does not contact emergency services.
