RFID remains entrenched in the retail sector, enabling new IoT applications such as smart shelves, self-checkout, and smart mirrors, in addition to expanding IoT adoption.
FREMONT, CA: The Internet of Things (IoT) begins with connectivity, but because the IoT is such a vast and complex field, there is no such thing as a one-size-fits-all communication solution. Each solution has its own set of strengths and weaknesses in terms of various network characteristics, making it best suited for particular IoT use cases. The most popular types of IoT wireless technologies are mentioned below.

RFID (Radio Frequency Identification)
RFID is a way of exchanging small amounts of data from an RFID tag to a reader over a short distance using radio waves. Technology has aided a tremendous change in retail and logistics up to this point. Businesses can follow their inventory and assets in real-time by attaching RFID tags to a variety of items and equipment, allowing for better stock and production planning as well as improved supply chain management. RFID remains entrenched in the retail sector, enabling new IoT applications such as smart shelves, self-checkout, and smart mirrors, in addition to expanding IoT adoption.
Low-Power Wide-Area Networks (LPWANS)
LPWANs are a novel phenomenon in the Internet of Things. This family of technologies is purpose-built to promote large-scale IoT networks stretching across enormous industrial and commercial campuses by offering long-range communication on small, inexpensive batteries that endure for years.
LPWANs can connect virtually any sort of IoT sensor, allowing for a wide range of applications, including asset tracking, environmental monitoring, and facility management, as well as occupancy detection and consumables monitoring. LPWANs, on the other hand, can only deliver small blocks of data at a slow rate, making them better suited to applications that do not demand a lot of bandwidth or are not time-sensitive. LPWANs are not all made equal. Today, licensed (NB-IoT, LTE-M) and unlicensed technologies exist, each with various performance degrees in important network factors. For example, while power consumption is a primary concern for cellular-based, licensed LPWANs, unlicensed alternatives prioritize Quality-of-Service and scalability. Standardization is another element to consider if one wants to assure long-term stability, security, and interoperability.
