Introduction 1 - 3
Baseband Processor
The Baseband Processor responsible for sending out appropriate commands in accordance to a selected tag
protocol to interrogating or accessing tags. Upon receiving the base band data from the Transceiver, the
Baseband Processor applies the appropriate algorithm to detect and extract the tag responses from the
incoming data stream. The data then will be buffered and sent to Controller for uploading to the Host.
Transceiver
The transceiver receives protocol command data from the Controller via Baseband Processor. Data from the
Baseband Processor will be modulated, up converted and sent to the antenna to power and accessing tags
that are resided within the field of the reader's antenna. Tags that receive reader's commands will respond
back with their data in the form of back scattering. Receiving through the reader's antenna, the Transceiver
down converts the tags responses to base band and passes the data to Baseband Processor for bit processing
in accordance to a Gen2 tag protocol.
