SYSTEM TOPOLOGY

RFID is a scalable system. In its minimalist configuration the micro-topology requires just four sub-systems, as follows:

1. Tag
2. Reader
3. Air Interface
4. Computer Communication and Control

The most demanding macro-topology involves pervasive tagging where sophisticated Readers are simultaneously interrogating multiple tags in a dynamic environment. In this scenario, anti collision algorithms are required in addition to data handling processes for large velocity data streams.
