What limits the possible.
WHAT POWER CONSTRAINS
How often a device can measure and transmit Which connectivity it can use How long it lasts between charges
WHY IT DOMINATES
A device requiring frequent battery replacement across a large fleet is operationally unaffordable.
WHAT CONNECTIVITY CONSTRAINS
How much data can be sent How often At what cost With what latency
WHAT PROCESSING CONSTRAINS
How much can be decided locally Whether encryption is practical Whether updates are possible
WHAT COST CONSTRAINS
Everything, at scale.
WHY
A saving of a small amount per device multiplies across thousands.
WHAT PHYSICAL ENVIRONMENT CONSTRAINS
Enclosure requirements Temperature and humidity tolerance Resistance to dust, water and impact Security against tampering and theft
WHY THAT MATTERS LOCALLY
Heat, dust, humidity and power instability are routine, and equipment rated for milder conditions fails.
WHAT ACCESS CONSTRAINS
How often a device can be visited.
WHY THAT MATTERS MOST
If a visit costs more than the device, the device must never need one.
WHAT TO DESIGN FOR
Never being touched again.
