8 Introduction to the RIFD System
8.1 RFID System
An RFID system is comprised of the control computer of the reader, antennas, antenna connection cables and the tags.
The gure 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 eld 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 ran-
domly, with equal distribution across the 52 available channels. Each channel is used for max. 400ms in an
interval of 20s.
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 specic applica-
tions, 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-specic control software can run directly on the
reader. Therefore, a stand-alone operation without permanent network connection is possible.

Introduction to the RIFD System
To be able to use the complete range of the reader performance in customer applications, we recommend
using the readers ARU3500 or RRU4500. It is not possible to run any customer applications on the basic
readers, i.e. ARU2400, ARU3400 and RRU4400.
8.2 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 exibility 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
8.2.1 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 exible 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%.

Tip PLS antennas have 4 LEDs to visualise customer applications.
The LEDs will be supplied and controlled by the RRU4xxx reader via the existing antenna cable.
Tip Note that for the internal antenna, the ARU3560* reader has all four polarisations already built in. The
ARU3560* reader cannot switch polarisation for external antennas.

8.2.2 Kathrein RFID Reader with Circular Switch-Beam Antenna
With the ARU8500 reader and its built-in circular switch-beam antenna (see FIg. 4), it is possible to staticly or dynami-
cally switch the antenna beam in order to track the moved goods.

Introduction to the RIFD System
The following settings are possible in any combination:
●antenna beam initial position (radiation 90°of the antenna)
●antenna beam switched 35° to the left
●antenna beam switched 35° to the right
The orientation of switching is in the longitudinal direction of the ARU8500.
Right-side beamLeft-side beam
Fig. 5: Circular switch-beam allocation
The ARU8500 reader is used to detect the movement of the transponder. This information will be added to the general
information about the transponder. With 50 antenna sweeps per second, the reader is fast enough to capture even the
objects moving at a speed of ≤ 10 km/h. At least two reads are necessary to determine the direction of movement.
8.2.3 ©KRAI SMSH (Smart Shelf) Antenna
Fig. 6: ©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 @KRAI antenna was developed for applications in the eld of point of sale, smart shelf applications 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 dierent 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 RRU4xxx Kathrein RFID reader. The ©KRAI control signals are transmitted via the
standard antenna cable.

that supports this function.
8.3 Further Reference Material
In order to congure 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 conguration of the reader are described in the Conguration 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 .
