1 - 2 MC3090Z RFID Mobile Computer Integrator Guide
RFID Components
Motorola RFID solutions offer low cost, long read range, and a high read rate. These features provide real time
end-to-end visibility of products and assets in the factory, distribution center, retail outlet, or other facility. The
MC3090Z RFID system consists of the following components:
•
Silicon-based RFID tags that attach to retail products, vehicles, trailers, containers, pallets, boxes, etc.
•
An integrated antenna that supports applications such as item level tracking and asset tracking.
•
An embedded radio module that powers and communicates with tags for data capture and provides host
connectivity for data migration.
Tags
Tags contain embedded chips that store unique information. Available in various shapes and sizes, tags, often
called
transponders
, receive and respond to data requests. Tags require power to send data.
There are several categories of tags based on the protocol they support, read/write memory, and power options:
•
Active RFID tags are powered by internal light-weight batteries, and also use these batteries to broadcast
radio waves to the reader.
•
Semi-passive RFID tags are also powered by internal light-weight batteries, but draw broadcasting power
from the reader.
•
Passive RFID tags are powered by a reader-generated RF field. These tags are much lighter and less
expensive than active tags, and are typically applied to less expensive goods.
Antenna
Antennas transmit and receive radio frequency signals.
Radio Module
The radio module communicates with the tags and transfers the data to a host computer. It also provides features
such as filtering, CRC check, and tag writing. The MC3090Z RFID mobile computer supports standard RFID tags
as described by EPCGlobal

Class 1 Gen2 protocol.
