-BESPA Overview
BESPA is a multi-protocol, multi-regional Radio Frequency Bidirectional Electronically Steerable
Phased Array unit, which is used to Identify and locate RFID tags operating in the UHF 840 – 960
MHz frequency band. A number of BESPA units may be used together with an ITCS Location
Processor to form an Intelligent Tracking and Control System (ITCS). BESPA comprises an
embedded multi-protocol, multi-regional RFID reader/writer transceiver connected to the patented
steerable phased array antenna system. BESPA is designed to be powered from Power-Over-
Ethernet and communicates with a host computer using standard Ethernet TCP/IP and UDP
protocol. Figure 1 illustrates the version of BESPA currently available. The ITCS-A-405 contains
the RF Controls RFC-40X RFID reader CCA.
 ITCS-A-405 are constructed using a Bi-directional Electronically Steerable Phased Array
(BESPA™) arranged to provide a single array with a circularly polarized gain of more than
6dBi and Linear Gains of more than 9dBi.
The particular units used in an installation will depend on the system design and determined by a
qualified applications engineer.
