It is essential for smart buildings to be able to evaluate the data collected from sensors and act on it automatically
FREMONT, CA: An IoT network is usually used in a specific implementation or industry, in this case, a smart building, and this is the subtle difference between the generic IoT and a smart world. A smart building can be a home, an office, a business, a warehouse, or a factory.
The owners or tenants of smart buildings can better manage their buildings by receiving actionable information about them or specific rooms within them. In general, smart buildings refer to commercial buildings, while smart homes refer to private homes, but much of their functionality is similar, so the terms overlap. A smart building reduces operating costs, improves occupant comfort, manages energy consumption, tracks core building assets, and complies with global regulations.

IoT networks control building systems and require complex monitoring to be smart.
IoT devices: IoT devices in smart worlds are usually wireless, but they are only sometimes. IoT devices can connect to the internet, either wirelessly or wired. IoT devices integrate with network connectivity and functional software like APIs, sensors, and actuators. With the Internet of Things, information can be transferred automatically between people, objects, and software without human intervention. A smart building can cater to consumer, commercial, or industrial buildings. IoT data can develop new end-user applications. IoT devices used in these buildings may differ, but they overlap. A connected vehicle may provide biometric access to the garage in a smart home environment. Smart consumer devices include cars, smartphones, laptops, entertainment systems, health monitors, and connected appliances.
Several smart commercial devices are being used in shops today, including inventory control, device tracking, security cameras, voice assistants, alarm systems, and biometric scanners. In the retail space, for example, security cameras may be used to monitor shoplifting and send automated alerts. Industrial sensors can monitor air quality in factories and ensure a consistently safe and healthy working environment with air quality meters, flow gauges, monitors for pipelines, robots, and pollution measurement products.
Smart building communications: Smart building technology stacks include connectivity technologies such as cellular and Low Power Wide Area Networks (LPWAN) and communication protocols such as Zigbee and Message Queuing Telemetry Transport (MQTT). Data protocols such as Zigbee and MQTT work in smart buildings. IoT devices and networks use MQTT as the de facto standard to ensure data communication from one device to another is encrypted and secure. MQTT is often used to connect to remote locations with limited network bandwidth.
IoT connectivity technologies: While LPWANs provide long-range communication for IoT sensors, they only transmit small amounts of data at a low speed. In addition to smart lighting and asset tracking, LPWANs are for energy management and asset monitoring. Cellular networks provide reliable but expensive broadband communication in video streaming applications, automated cars, connected health, and industrial applications. Bluetooth Low-Energy (BLE) is applicable in private residences for data transfer from and to cloud applications on smartphones, fitness devices, and medical devices. With RFID tags, small amounts of information can be transmitted from a tag to a reader over a short distance using radio waves. Retail stores often use RFID tags.
The IIoT uses LPWA as the fastest-growing wireless connection technology, whereas IoT uses DSL, Ethernet, and PSTN. The latter is the dominant mode of connectivity in IIoT applications.
