Professional Installation Guidelines for the U.S.
5 Professional Installation Guidelines for the U.S.
5.1 Installation Personnel
UHF RFID readers require professional installation!
►You must be a professional installer with RF and related knowledge of regularizations.
►The installation requires trained professionals to access and setup the system.
►The system has to be installed by professional installation personnel only. Other users shall not
attempt to install the device or change the settings.
5.2 External Antennas
►You must follow Part 15 of the FCC rules, specically Part 15.203 pertaining antenna requirements
of an intentional radiator.
►Make sure to use a antenna with a gain of 13 dBi or less.
►Only use antennas which have been approved by the applicant. The use of none-approved anten-
na(s) may produce unwanted spurious emissions or excessive RF transmitting power which may
lead to the violation of the FCC/ISED limit.
5.3 Final Output Power
WARNING
►Carefully select the installation position.
►Make sure that the nal output power does not exceed the limit set in regularizations. The violation
of the rule could lead to serious federal penalty!
If you are not a professional installer, STOP
►Do not proceed any further with the installation.
►Do not install the unit or change the settings.

NOTICE
Risk of harmful radio communication interference!
Following corresponding tests, it has been ascertained that this unit adheres to the limit values for
class B digital units in accordance with Part 15 of the FCC regulations. These limit values are intended
to provide private user's systems with appropriate protection against harmful radio interference. This
unit generates and uses energy in the radio frequency range and is also able to radiate this energy; if
it is not installed and used in accordance with the regulations, the unit may cause harmful radio com-
munication interference. However, there is no guarantee that interference will not occur in a specic
system. If this unit causes harmful radio or television reception interference, which can be ascertained
by switching the unit on and o, we recommend that the user attempts to rectify this interference via
one or more of the following measures.
►Turn the unit on and o to make sure the radio or television reception interference is caused by the
unit.
►Realign the receive antenna or change its position.
►Increase the distance between the unit and the receiver.
►Plug the unit into a socket in a current circuit other than that to which the receiver is connected.
►Seek advice from the retailer or an experienced radio/television technician.

7 Introduction
7.1 RFID UHF Antenna
The Kathrein antenna family consists of various UHF reader antennas, which can meet the needs of virtually any RFID
application. The antennas are divided into four product lines with respect to the reading range: low range, mid range
and wide range antennas. The fourth group are the Smart Shelf antennas.
This allows up to 4 standard antennas to be used simultaneously in any combination and range with Kathrein RFID
readers. With the Kathrein ©KRAI SMSH antennas, even up to 32 antennas can be controlled by one Kathrein RAIN RFID
reader. This modularity is only possible with Kathrein RFID readers and antennas.

Product Description
7.2.2 KRAI Antennas
KRAI antennas are a special variant of Kathrein antennas. This allows the antenna properties to be changed dynam-
ically. These changes are controlled by the Kathrein RFID reader via the existing antenna cable. External controls or
connections are not necessary. This improves the reading properties in the system and simplies the installation of the
antennas.
The designation KRAI stands for Kathrein RFID Antenna Interface
The following antennas are available and functions can be fullled:

8 Product Description
8.1 Low Range Antenna
The low-range antennas are a unique series of antennas developed exclusively for the reading range < 20 cm. On the
one hand, this is necessary to detect reading positions very precisely, as the transponder is only read when it is spa-
tially very close in front of the antenna. On the other hand, it is very easy to write precisely on transponders with the low
range antennas, because only the tag that is physically close to the antenna can be written to. A complex selection pro-
cess is not necessary.
With dimensions of 90 x 63 mm, these antennas have a high eld concentration in the near eld, with signicantly
reduced antenna gain in the far eld. With these characteristics, the antennas achieve excellent read/write performance
at ranges of up to 10 cm with a typical selectivity of 5 cm. Low range antennas are available as LORA (Low Range) and
ULORA (Ultra Low Range). The ULORA antenna is designed to read dipole-shaped tags ("far-eld tags") at extremely
close range. These antennas can also read loop-shaped tags ("near-eld tags") up to 3 cm. The LORA was developed for
longer ranges and is particularly suitable for near-eld tags.

8.2 Mid Range Antenna
The MIRA 100° was developed for applications in the area between near eld and far eld. Particular importance was
placed on creating a compact construction to enable integration into environments with limited space. Read ranges of
over 2 m are still possible even with dimensions of 156 x 126 mm. MiRa also oers increased selectivity at lower reading
distances compared with conventional antennas. This antenna design is therefore also suitable for use in the so-called
transition area (0 – 1m) with a variety of transponder types.
The S-MiRa antenna is optimised for the range 0-1 m and can also be used excellently in highly reective areas (e.g. in
machines or in metal construction).
The typical area of application for the Mid Range antennas is in logistics, where the antennas are used for the detection
of containers on conveyor belts. In addition, the antenna can be used for access systems because, despite its small
dimensions, it can cover a reading zone of up to 2m. If the installation space for antennas is limited, the MiRa antenna
can also be chosen for gate applications.

Antenna Directivity
The antenna directivity shows the propagation characteristics of the EM eld of the antenna. The half power beam width
and the front to back ratio can be read from it.

8.3 Smart Shelf Antenna
The SMSH antennas are ideal for use in shelving. This can be planned during installation, but can also be retrotted for
existing shelves. The height of the antenna is < 20mm so that the available installation space is retained.
The SMSH antenna impresses with a selective reading zone. The range between reading and non-reading is maintained
with a high degree of separation and repeatability. The reading range is a cube with the groundplane of 30 cm x 30 cm
and covers the range 0 - 3m. Due to the ideal front-to-back ratio, reading also takes place exclusively in front of the
antenna. This also means that metal shelves have no negative eect on the reading performance.
The ideal use of these antennas is for eKanban shelves or in the retail sector. But also for applications where the height
of the antenna is limited. e.g. for laundry collection where the antenna can be mounted under the table.
Two options are available for the antenna. The standard SMSH antenna, which can be used as a single antenna, and
the KRAI version of the SMSH antennas, which, with a Kathrein reader, allows a unique RFID system in which the SMSH
antennas are cascaded. This makes it easy to equip a large area of a shelf with antennas that are all controlled by one
reader.
©KRAI SMSH (Smart Shelf) Antenna
The SMSH KRAI antennas, which have an input and an output port, are simply connected in a daisy chain arrangement.
The Kathrein reader initialises all antennas in the network and can thus control a maximum of 32 (=4 * 8 antennas). The
reader collects all the read results and assigns them to each individual SMSH antenna, so that a direct image of the
container placement of the shelf can be created.

Antenna Directivity
The antenna directivity shows the propagation characteristics of the EM eld of the antenna. The half power beam width
and the front to your ratio can be read from it.
