Introduction to the RIFD System
7 Introduction to the RIFD System
7.1 RFID System
An RFID system is comprised of the control computer of the reader, antennas, antenna connection cables and the tags.
The figure below shows the schematic structure of the system:
Ethernet
or
serial interface
RFID UHF
Gen2 Tag
Fig. 1: RFID system (example)
The tags consist of an antenna and a small chip. The chip is the true carrier of the information, the EPC (
Electronic Product
Code
) number. This number can identify products or product groups. Alternatively, the EPC can be overwritten with new
information.
To read the tag information, the reader switches on an RF carrier by means of a selected antenna, thus supplying the
tags in the RF field with energy.
To read the information from a tag, it is necessary to inventory the tags and then select a tag from the population of
tags. Upon successful completion of the inventory, the EPC number of each tag can be read and sent to the PC. It is
possible to attach additional information to the EPC, for example, the antenna which read it or the time at which it was
read.
NOTICE
The reader operates using the frequency hopping process to avoid faults and interference between readers.
Within the FCC area, this procedure is mandatory. The reader changes its transmission frequency randomly,
with equal distribution across the 52 available channels. Each channel is used for max. 400ms in an interval
of 20s.
The
ReaderStart v3
software can be used for testing and parametrising.
The communication between the
ReaderStart v3
and the reader is based on the DLL (
Dynamic Link Library
), which includes the
communication protocol, see
Communication Protocol Kathrein RFID UHF Readers
. For specific applications, the user can build its
own control software based on the reader DLL. The DLL includes all the relevant commands and functions required to
control the reader.
It is necessary for the user to create his own control software. The user-specific control software can run directly on the
reader. Therefore, a stand-alone operation without permanent network connection is possible.
15 of 112
To be able to use the complete range of the reader performance in customer applications, we recommend
using the readers ARU3500 or RRU4500. It is not possible to run any customer applications on the basic
ARU3400 and RRU4400 readers.
7.2 Kathrein RFID Antenna Interface ©KRAI
With the ©KRAI product series, Kathrein has introduced a revolutionary system. By using Kathrein ©KRAI antennas, it is
possible to increase the flexibility due to having several antenna properties at one installation point (in case of PLS and
CSB antennas) and functionality (when cascading SMSH antennas).
©KRAI consists of a digital control bus which enables connection between the RFID reader and the RFID antennas to
allow control and regulation tasks in remote antennas
7.2.1 WIRA 70 ©KRAI Polarisation Switch Antenna (PLS)
Fig. 2: PLS antennas connected to the reader
With the ©KRAI PLS antenna, built as a WiRa 70° antenna, the polarisation can be switched statically or dynamically. The
following settings are possible in any combination:
●circular LHCP
●circular RHCP
●linear horizontal
●linear vertical.
It is possible to select the best polarisation for wide-range application and to carry out a flexible adjustment of the
antenna on site.
Furthermore, it is possible to increase the read rate via the switching circular LHCP/RHCP by up to 33%.

7.2.2 ©KRAI SMSH (Smart Shelf) Antenna
Fig. 4: ©KRAI smart shelf antennas connected to the reader (cascaded)
Up to 8 ©KRAI smart shelf (SMSH) antennas can be cascaded per reader port; 8 antennas x 4 ports = 32 SMSH antennas
in total.
The SMSH 3030 @KRAI slave antenna was developed for applications in the field of point of sale, smart shelf applica-
tions and Kanban solutions. The antenna is characterised by an extremely homogeneous read zone, which is emitted by
the high front-to-back ratio. Therefore, it is suitable for static detection of multiple transponders. Due to the extremely
thin design, the antenna module can be integrated into dierent applications.
The antenna is equipped with an intelligent bypass circuit that allows for cascading up to 8 SMSH antennas per reader
port. The control is done by a RRU4xxx Kathrein RFID reader. The ©KRAI control signals are transmitted via the standard
antenna cable.

Introduction to the RIFD System
7.3 Further Reference Material
In order to configure the reader correctly and adapt it to the respective application, it is necessary to have detailed
knowledge of the EPCglobal standards of GS. This standard describes the principle of operation of the interface between
the tag and the reader.
The parameters available for the configuration of the reader are described in the
Configuration Manual for Kathrein RFID UHF
Readers
.
The reader is controlled via the Kathrein reader protocoll (KBRP), the current version of which is described in detail in the
Communication Protocol Kathrein RFID UHF Readers

8 The Reader
8.1 Functional Specification
The Kathrein RFID (Radio Frequency Identification) reader of the RRU 4xxx and ARU3xxx series is a multi-protocol-ca-
pable device for reading active and passive RFID tags in the frequency range from 865 to 868 MHz for Europe and 902
to 928 MHz for the American market. Based on the latest RFID standards, such as
EPC Gen2v2
/ISO 18000-63, the Kathrein
RRU 4xxx series support all market leading transponder chip features for security, authentication and encoding. As sup-
plied, the unit can read and write tags in accordance with the
EPC Gen2v2
standard.
It is possible to load additional protocols using software updates.
The device has a maximum of four external antenna ports for connection of the transmission/reception antennas for
communication with RFID tags.
For integration into a variety of infrastructures, the device has dierent communication interfaces, depending on the
variant. The power supply is provided either by a 4-pin M12 panel connector in A coding or by PoE+ according to 802.3at
(10–57)1).
The Kathrein UHF RFID reader system RRU 4xxx is characterised by great flexibility in regard to RFID applications. One
reason for it is the wide variety of reading devices compatible to each other, which allows to select a reader from the
Kathrein product portfolio ideally suited for the respective application. Another reason for this flexibility is the wide
range of parameters for configuring the reader firmware.
