Sites placed for coverage, not for access.

“Capability is a depleting resource to be spent, not a fixed budget to be defended.”

Whitepaper, §5

Relay and cell sites sit where coverage is needed, not where technicians live. A failed controller can mean a truck roll, or a helicopter.

Mru Field runs on the processors already in the equipment. When one fails and nobody can come, it continues on the ones left and delivers only results it can check. Status: decision core at TRL 3; first field pilot planned for 2027.

01

## Computers fail one by one

Radiation, heat and age take out processors and memory. Nothing is replaced until the next visit.

02

## Power runs down

Batteries fade and panels foul. The system has to do less, on purpose, and keep the important part going.

03

## No one to ask

When two computers disagree, there is no operator to say which one is right.

## Three computers. Then two. Then one, still working.

Most redundant systems stop when they lose their majority. Mru Field steps down instead, and says which mode it is in.

3 alive · vote

A B C

Three computers vote. One bad result is outvoted.

2 alive · compare

A B C

Two compare. A known-answer test finds the faulty one.

1 alive · self-check

A B C

The last one checks its own work and keeps the site reporting, at half speed.

Power

Grid, solar or generator

Link

Its own backhaul

Visits

Truck roll or helicopter

Service life

Years

## Questions

Does Mru Field need new hardware?

No. It is software for the processors you already deploy. It runs beside your control code and decides which computer to trust as parts fail.

Can it run beside existing site controllers?

Yes. It decides which of several computers to trust. Your site logic stays the same.

How do we start?

Use the form below. We first model your hardware and show what each redundancy design returns over its whole life. Then we plan a pilot on your own equipment.
