Pacchanta, Ocongate · 26 July 2026
A message crossed.
The question changed.
A day to bring the prototype into contact with the terrain and the people. The result includes the message that arrived and everything that still made it difficult to use.
The documented result
The message arrived.
The bell rang.
A request for help was simulated from the trail. The team at the base received it and the bell rang at the other end.

The report does not provide a delivery rate, a coverage figure or evidence that a complete network could be sustained in the corridor. Nor does it establish that a person in a real emergency received help.
The prototype box brought together an access point, a web application, a case record and a bell. A radio link enabled the demonstration without relying on the internet. The test does not turn those components into a validated service.
Consult the original reportWhat changed the conversation
The signal arrived.
A response needed more.
During the fieldwork
Knowing which case
is being attended to.People asked to distinguish new calls from cases already attended to, read the names more clearly and explicitly say who was taking responsibility. These are coordination needs, not just display preferences.
Being able to return
to the application.A responder left the web application and could not re-enter it directly. They had to use the browser history while the alarm was still sounding. The experience was not consistent across devices.
Hearing and reading
in real conditions.The bell was considered too weak, and the screen was difficult to read in sunlight. A working component does not establish that a person can use it when they need it.
During the later inspection of the node
The clock did not provide
trustworthy time.The node had no reliable time source. The record’s ordering could help interpret the sequence, but did not justify assigning trustworthy times to events. Content integrity and reliable time are separate questions.

What remains open
Return to the field.
Do not get ahead of it.
The report proposes mapping locations with the community, reviewing the infrastructure design, agreeing protocols for use and governance, and verifying the system before deployment. It does not establish that these steps have been completed.
Proposed improvements include reviewing access across devices, making cases easier to read, improving the audible alert and providing reliable time. Each correction needs its own test.
Before depending on a system
This demonstration does not authorise reliance on the prototype to call for help. It is not an emergency service or a validated early-warning system. A received alert does not guarantee that help arrives.
The reference to Pacchanta identifies the report’s location. It does not imply general permission for new studies, the use of images or representation of the community.
