What Is Short-Range Wireless Communication?
Short-range wireless communication uses radio frequency (RF) signals to enable communication between computers and devices or products and scanners. RF signals can transmit data at high speeds with low power consumption. They can travel up to 100 meters from the source, depending on the technology.
What Is Radio Frequency Identification (RFID)?
RFID technology, which has been used for decades, utilizes a chip to enable short-range communication in various applications. The chip, either placed in or attached to an object, stores information. This information is “unlocked” when a scanner reads the object.
Most of us use this technology every day, as it’s found in:
- Credit cards
- Passports
- Retail clothing tags
- Hotel card keys
- Pet chips (to store health and owner information)
- Warehouse inventory
What Is the Difference between RFID Chips and Wireless IoT Devices?
In terms of RFID’s use in Internet of Things (IoT) devices, RFID chips can be complementary to IoT applications. However, they do not accomplish the same goals as short-range wireless IoT devices.
While RFID chips store information, wireless IoT devices, which use embedded sensors, enable communication and data relay between machines and networks. This capability is a key feature of industrial IoT (IIoT). IIoT mission-critical applications rely on real-time data collection and analysis to improve productivity, decision-making and worker safety.
What Are the Use Cases for Wireless IoT Devices?
Smart Agriculture and Hydroponics
Smart farming and precision agriculture incorporate this technology to make farm-to-market more efficient and productive. They deploy IoT sensors, or edge endpoints, to connect everything from irrigation systems to soil and animal production.
Some endpoints depend on short-range wireless technologies, such as Wi-Fi and Bluetooth® wireless technology. Others use cellular due to distances and RF coverage needs.
With a goal to maximize food production, the technology empowers farmers with data to make good business decisions related to:
- Reducing resource consumption (e.g., water, grain, fertilizer, pesticides)
- Minimizing runoff and soil erosion
- Adding efficiency to overall operations and product distribution
Deep Rooted, formerly Clover, is an India-based greenhouse agritech startup supplying farm-fresh local produce direct to consumers in Bangalore. It deploys wireless sensors to monitor plant growth in its greenhouses. Aggregating data from many locations within the greenhouse campus allows them to improve growth protocols. This enhancement yields healthier plants and a more plentiful harvest.
From orchards to cattle ranching, farms are utilizing IoT solutions to monitor multiple drivers affecting their bottom line, including:
- Temperature
- Soil conditions
- Contaminants
- Water quality
These capabilities can be applied to other industrial settings in which the entire process can be monitored within a closed-loop environment.
Smart Construction
GreenVibe, an Israel-based startup, sought to spearhead a global construction industry revolution by maximizing precision and efficiency in concrete making. The company utilizes embedded IoT modules for its sensors in addition to IoT connectivity solutions and platforms. The total solution enables GreenVibe’s customers to collect real-time data from the concrete, including:
- Strength
- Temperature
- Workability
- Density
- Humidity
The IoT sensors are left in the concrete after serving their purpose. They are inexpensive and consume little power yet contain robust communication ability during (but not after) the hardening process. These sensors are cost-effective and valuable for such a robust environment.
