Spec Sheet

ALR-9900 Enterprise RFID Reader
High Performance, Easy to Deploy, Easy to Manage
When operating in Autonomous Mode, the reader
will continue to collect up to 2500 tag records even
if the LAN connection is interrupted. Upon recovery
of the LAN connection, middleware can download
accumulated tag data from the reader.
Interference Management
The ALR-9900 offers several methods for interference
mitigation that provide a powerful solution to the
challenge of noisy environments.
Good Citizen:
EPC Gen 2 Dense Reader Mode
The ALR-9900 is compliant with the EPC Gen 2 Dense
Interrogator specifi cation, which reduces interference
impact on other readers. The mode signifi cantly
reduces the out-of-channel noise introduced by the
reader, thereby enabling larger numbers of readers to
coexist without reducing read rates.
Noise Resistant:
Strong Filtering for Interference
Rejection
The powerful, dynamically adjustable signal processing
architecture of the ALR-9900 ensures strong
interference rejection in the presence of other readers
or devices.
Intelligent Operator:
Event-triggered operation and
Autonomous Mode
The Autonomous Mode functionality of the Alien
Reader Protocol enables the reader to collect tag data
when triggered by external events detected by photo
eyes and other sensors. In this mode, readers are
activated only when needed, thereby reducing the
number of readers operating at any given moment, and
the resulting ambient noise level.
High Performance, Easy to Deploy, Easy to Manage
