Read Range up to 20ft**
WJ Communications’ WJR7000 UHF RFID
reader module is designed to enable RFID UHF
Gen2 capability for handheld readers, printers and
forklift readers. This allows original equipment
manufacturers, value added resellers and system
integrators to reach a broad spectrum of end cus-
tomers. WJ’s capability to configure WJR7000
modules for different country specific UHF fre-
quency requirements, to provide 1/2 watt Gen2
dense reader mode and to implement a 40/240
KHz data rate will enable high performance solu-
tions that can be deployed worldwide. The
WJR7000 is backwards compatible with the
MPR7000.
The 0.5-watt (+27dBm) WJR7000 reader module
operates in the UHF frequency band (902-928
MHz) used by North America and some Asia-
Pacific regions. The reader includes the RF, digi-
tal circuitry and embedded firmware required for
ISO18000-6C (UHF Gen2) and Class 0/0+ stan-
dards. The API command set enables customers
to control RF output power per command accord-
ing to their application needs. WJ provides free
demonstration software for quick evaluation, an
open source DLL and API for simple integration
and standard 3.3-5V CMOS serial communication
for universal connectivity.
Applications
Low Power Mobile RFID Devices for item level tracking
RFID Enabled Handheld Readers
RFID Enabled Fork Lift Readers
RFID Portal Readers
