<h1>RFID vs BLE: A Comprehensive Comparison for Modern Applications</h1> <p>In my years of working on asset tracking and smart inventory solutions, the debate between <strong>RFID vs BLE</strong> has been a constant. I've personally implemented systems using both, and my experience is that the "best" technology is entirely dependent on the specific use case, budget, and required data granularity. One project that stands out involved tracking high-value medical equipment in a large hospital. We initially piloted a passive RFID system, which was excellent for bulk scanning at doorways, but we lacked real-time location granularity within a room. This personal experience directly shaped my understanding of the fundamental trade-offs at play.</p> <h2>Core Technology and Operational Principles</h2> <p>The fundamental distinction in <strong>RFID vs BLE</strong> lies in their communication paradigm. RFID (Radio-Frequency Identification) is primarily for identification via simple data transmission (like a serial number) from a tag to a reader, often without a power source in the tag (passive) or with a small battery (active). BLE (Bluetooth Low Energy), a subset of the Bluetooth standard, is designed for low-power, bidirectional data communication between intelligent devices, enabling complex data exchange and connectivity.</p> <h3>Technical Specifications and Parameters</h3> <p>When evaluating <strong>RFID vs BLE</strong> for a project, precise technical specifications are critical.
