Definitions - Internet of Things (IoT) Lens

Definitions

Sustainability encompasses seven focus areas:

The following is a list of sustainability-specific definitions in the IoT Lens.

  • Energy efficiency or power efficiency: Used interchangeably in this document.

  • Truck roll (or site visit): The act of sending a technician to a site to resolve an issue. This has impacts both from an operational cost perspective (technician labor, fuel costs, maintenance running to hundreds of dollars per device) as well as carbon footprint (emissions, wear and tear). Consequently, designing IoT devices to minimize the need for truck rolls is a key imperative.

  • Battery life: Refers to how long a device can run on a single charge.

  • Battery lifetime: Refers to how long the battery can be in operation before needing replacement.
