BLE uses an adaptive frequency hopping (AFH) mechanism across 40 channels, each with a 2 MHz bandwidth, ensuring minimal interference and enhancing data transmission reliability.

BLE’s connection protocols include a “star topology,” in which a central device connects to several peripherals, each with unique IDs for secure data transmission. Devices communicate through either advertising, which is a one-way broadcast ideal for beacon applications, or a connected mode, allowing two-way communication. These flexible modes, combined with low-latency response times, make BLE suitable for IoT devices and applications where power efficiency is critical.


Explanation of RFID’s Operating Frequencies: Low, High, and Ultra-High Frequencies

Radio Frequency Identification (RFID) uses electromagnetic fields to transfer data between a tag and a reader, enabling identification and tracking. RFID operates across various frequencies, each with distinct characteristics, making it versatile for different applications:

  • Low Frequency (LF): Operating between 125-134 kHz, LF RFID has a short-read range (up to 10 cm) and is less affected by interference from metals or liquids. It’s commonly used in animal tracking and access control due to its reliability in challenging environments.
  • High Frequency (HF): HF RFID operates at 13.56 MHz with a typical range of up to 1 meter. It supports NFC (Near Field Communication) protocols and is widely used in contactless payment systems, access control, and library management. HF systems provide faster data transfer and are effective in applications needing moderate read distances.
  • Ultra-High Frequency (UHF): Operating between 860-960 MHz, UHF RFID can achieve ranges of up to 12 meters, enabling applications in supply chain management, inventory control, and asset tracking. However, UHF signals can be more susceptible to interference from metals and liquids, requiring thoughtful implementation in specific environments.
