SASL OVERVIEW
SASL is a multi-protocol, multi-regional Radio Frequency Signal Acquisition & Source Location unit,
which is used to Identify and locate RFID tags operating in the UHF 860 – 960 MHz frequency
band. A number of SASL units may be used together with an ITCS Location Processor to form an
Intelligent Tracking and Control System (ITCS). SASL comprises an embedded multi-protocol,
multi-regional RFID reader/writer transceiver connected to the patented steerable phased array
antenna system. SASL is designed to operate from AC mains power and communicates with a host
computer using standard Ethernet TCP/IP and UDP protocol. Figure 1 illustrates the two versions of
SASL currently available. Both versions are equipped with identical RFID reader and Array
Controller.
 ITCS-A-200 is constructed using eight Bi-directional Electronically Steerable Phased Arrays
(BESPA™) arranged to provide a single array with a circularly polarized gain of 11.6dBi.
 ITCS-A-202 is constructed using four BESPAs arranged to provide a single array with a
circularly polarized gain of 7.6dBi.
The particular units used in an installation will depend on the system design and determined by a
qualified applications engineer. The two models may be intermixed as required in a single ITCS
system.
