AI Overview
2.4GHz long-range active cards are battery-powered radio frequency identification (RFID) tags, often used for vehicle parking, personnel tracking, and asset management. They offer read ranges typically between 10 and 100 meters, utilizing GFSK modulation and the 2.4-2.5GHz ISM band. These tags are ideal for high-speed identification, anti-collision, and harsh environments.
Key Features and Benefits
- Long-Range Detection: Typically 10 to over 100 meters.
- Active Technology: Powered by internal batteries (e.g., CR2302 or similar).
- Operating Frequency: Operates in the 2.4GHz - 2.5GHz ISM band.
- Real-time Tracking & Security: Used for locating personnel/assets and often feature tamper-resistant alerts.
- High Anti-collision: Some systems allow tracking multiple cards (up to 100 tags/s) simultaneously.
- Durability: Often rated for industrial or outdoor use (e.g., IP67).
