Using mobile networks.
WHAT IT PROVIDES
Coverage wherever mobile service exists No dependence on local infrastructure Managed by the operator
WHAT IT COSTS
A subscription per device Power, for standard cellular Module cost
WHAT LOW-POWER CELLULAR VARIANTS PROVIDE
Far lower power and cost, for small amounts of data.
WHAT THEY TRADE
Data rate and latency.
WHAT TO ESTABLISH BEFORE SELECTING ONE
Whether the local operators actually support it, and where.
WHY THAT MATTERS ENORMOUSLY
Support varies by operator and by area, and specifications do not reflect deployment.
WHAT TO TEST
Coverage at the actual deployment sites, with the actual hardware.
WHAT SIM OPTIONS EXIST
Standard removable cards Embedded modules soldered in Programmable profiles switched remotely
WHAT EMBEDDED MODULES PROVIDE
Resistance to removal, vibration and moisture.
WHAT REMOTE PROFILE SWITCHING PROVIDES
Changing operator without a site visit.
WHY THAT MATTERS
Operator performance varies, and visiting a fleet is expensive.
WHAT TO NEGOTIATE
Data plans suited to very low usage across many devices.
WHAT TO MONITOR
Data consumption per device, which reveals faults.
