What is the foundation protocol?

image_print

The term “foundation protocol” is sometimes used to describe the second-generation EPC air interface protocol, or UHF Gen 2. EPCglobal calls it the foundation protocol because Gen 2 is designed a way that higher-class tags will also talk to readers. These higher-class tags will have more memory, encryption capabilities, the ability to use a battery to broadcast a signal to a reader and the ability to communicate information from temperature and other sensors. The Foundation Protocol is expected to be approved by the end of 2004.
