- CAN bus
- Controller Area Network, the internal communication network in most vehicles and much industrial machinery. Telematics devices can read CAN data for fuel use, engine hours, RPM and fault codes.
- Cold chain excursion
- Any period when a temperature-sensitive product goes outside its permitted range during storage or transport. Excursions must usually be recorded, investigated and may require stock to be quarantined.
- Condition-based maintenance
- Servicing equipment when a measured condition such as vibration, temperature, pressure or runtime indicates it is needed, instead of on a fixed calendar. Aims to reduce both unexpected failures and unnecessary servicing.
- Data residency
- The requirement or practice of storing and processing data within a specific country’s borders. In Saudi Arabia, it is shaped by national regulation, sector rules and contractual obligations.
- Digital twin
- A live digital representation of a physical asset, site or process, combining its static record with current sensor data, so its state can be monitored, analysed and simulated.
- Edge computing
- Processing data close to where it is generated, on a device or local gateway, instead of in a central cloud. Reduces latency and bandwidth, and keeps sites running when connectivity drops.
- Geofence
- A virtual boundary drawn around a location, such as a depot, customer site or restricted zone. Entering, leaving or dwelling inside it can trigger rules, alerts or records.
- Journey management
- The planning, approval, monitoring and close-out of road journeys to control risk, covering route, driver fitness, rest breaks, check-ins and response when a journey goes off plan.
- LoRaWAN
- A low-power, long-range wireless protocol using unlicensed spectrum. Devices communicate with gateways that an organisation can deploy itself, making it useful for campuses, farms and sites with limited cellular coverage.
- LwM2M
- Lightweight Machine-to-Machine, an OMA SpecWorks standard for remote device management and telemetry. Commonly used with low-power devices for configuration, firmware updates and monitoring over constrained networks.
- MQTT
- A lightweight publish and subscribe messaging protocol widely used for IoT. Devices publish messages to topics on a broker, which forwards them to subscribers. Well suited to constrained devices and unreliable networks.
- MTBF
- Mean Time Between Failures: the average operating time between breakdowns of a repairable asset. Used to compare reliability and to judge whether maintenance changes are working.
- Multi-tenancy
- An architecture where one platform serves many separate customers or business units, each with isolated data, users and configuration, while sharing the underlying infrastructure.
- NB-IoT
- Narrowband IoT, a low-power cellular technology running on licensed spectrum. Designed for devices sending small amounts of data infrequently, such as meters and sensors, with good indoor penetration and long battery life.
- NFC fleet card
- A contactless card or tag used to authorise and record fleet spending, such as fuel or car care, linking each transaction to a vehicle or driver for control and reconciliation.
- OBD-II
- On-Board Diagnostics, a standard vehicle port and set of diagnostic codes, common on light vehicles. Plug-in devices use it to read speed, engine data and fault codes without complex installation.
- OPC UA
- Open Platform Communications Unified Architecture, a vendor-neutral industrial standard for secure data exchange between machines, controllers and software, common in manufacturing and process industries.
- OTA update
- Over-the-air update: delivering firmware or configuration changes to devices remotely. Good practice includes staged rollouts, verification and the ability to roll back a faulty release.
- RFID
- Radio-Frequency Identification, which uses tags read wirelessly by readers. Passive tags need no battery and suit inventory and gate checks; active tags broadcast and offer longer read ranges.
- RTLS
- Real-Time Location System, used to locate assets or people indoors or within a defined site, typically using BLE, UWB, Wi-Fi or RFID infrastructure where GPS does not work reliably.
- SCADA
- Supervisory Control and Data Acquisition, industrial systems used to monitor and control plants, pipelines and utilities. IoT platforms often integrate with SCADA rather than replacing it.
- Telematics
- The collection and transmission of data from vehicles and mobile assets, typically location, speed, engine data and driver behaviour, used to manage fleets, safety, fuel and maintenance.
- Time-series data
- Measurements recorded against timestamps, such as temperature every minute or location every few seconds. Most IoT data takes this form and needs storage optimised for high write volumes and time-based queries.
- Webhook
- An HTTP callback that sends data to another system automatically when an event occurs, such as posting an alert to a ticketing tool, without that system needing to poll for changes.
