For antenna configurations where it is possible to be briefly or constantly within the transmission range of the antennas, as in loading ramps, for example, minimum distances must be maintained.

The ICRP (International Commission of Radiological Protection) has worked out limit values for human exposure to HF fields that are also recommended by the ICNIRP (International Commission of Non Ionizing Radiological Protection). In German legislation on emissions (since 1997), the following limit values apply. These can vary according to frequency:

The limit values for the 900 MHz reader antenna alternating field are thus:

Electrical field strength: E = 41.25 V/m

Magnetic field strength: H = 0.111 A/m

HF power density: E x H = 4.57 W/m

At a transmission frequency of 900 MHz, the wavelength of the electromagnetic wave λ is approximately 0.34 m. For distances less than 1 λ in the near field, the electrical field

strength (1/r) diminishes exponentially to the power three over distance, and for distances greater than 1 λ, it diminishes exponentially to the power two over distance.

The horizontal line at 41.25V/m marks the "safety limit value".

For the maximum permitted transmit power (1/r

) in accordance with ETSI (2 W ERP), the "safety distance" is d = 0.24 m. This means that personnel should not remain closer than 24 cm to the transmitter antenna for extended periods (for several hours without interruption). Remaining within the vicinity of the antenna for a brief period, even for repeated periods (at a distance < 0.24 m), is harmless according to current knowledge.

If the transmitter power is set lower than the highest permissible value (2 watts ERP), the "safety distance" reduces correspondingly.

SIMATIC RF600 is an identification system that operates in the UHF range. UHF technology supports large write/read distances with passive transponders.

The SIMATIC RF650R or RF680R readers (write/read devices), fitted for example on the gates of a warehouse, automatically record every movement of goods, and signal these to the higher-level systems. The data is filtered and compressed there by data management software at the control level for example to generate the incoming goods transaction for the ERP (Enterprise Resource Planning) system at the business administration control level. At the same time, the delivery can be automatically checked for correctness and completeness prior to storage by means of the electronic delivery list.

4.2 Possible system configurations

This scenario shows a possible solution for monitoring and controlling the infeed of material to a production line. The objective is to provide the right material at the right time. This can be particularly useful in plants with frequently changing manufacturing scenarios for ensuring that incorrect infeed and downtimes are minimized.

The conveyor moves different transport containers past the readers in an arbitrary alignment. The RFID transponder is, however, always applied to the transport containers with the same alignment. The transponders in this scenario are transponders of the type SIMATIC RF680T.

The conveyor belt has a maximum width of approximately 80 cm in this example. The transport speed is up to 2 m/s. With this arrangement only a single RFID transponder needs to be detected each time (single-tag).

In this scenario a SIMATIC RF680R is used as the reader. Optimum reading reliability is ensured by four external SIMATIC RF660A antennas in a portal arrangement. When the distances to or between metal containers are very limited, the SIMATIC RF620A antenna is a good alternative. The SIMATIC RF680R reader reads the information of the transponder on the transport containers and forwards it to the SIMATIC S7 controller that controls the next actions depending on the transponder information.

Scenario for workpiece identification

Features of the scenario

4.2 Possible system configurations

A typical characteristic of modern manufacturing scenarios is their multitude of variations. The individual data and production steps are stored in the transponder of a tool holder or product. These data are read by the machining stations during a production process and, if necessary, tagged with status information. This can be used to dynamically identify which production step is the next in the series. This has the advantage that the production line can work automatically without the need to access higher system components. The use of RFID therefore increases the availability of the plant.

RFID tags are attached to workpiece holders. Their spatial orientation is always identical. With this arrangement, only a single transponder needs to be detected each time (singletag). The transponders in this scenario are transponders of the type SIMATIC RF640T.

The SIMATIC RF685R reader reads the information from the transponders with its integrated antenna and transfers it to the SIMATIC S7 controller. Depending on the stored transponder information, the SIMATIC S7 controller different control tasks, for example, automatically providing a suitable tool for an industrial robot at the correct time.

In this scenario, bulk acquisition is necessary because several objects must be detected at the same time.

The SIMATIC RF680R reader uses two external antennas in a portal arrangement to read the information from the transponders on the passing items and transfers it to the SIMATIC S7 controller via a communications module. The SIMATIC S7 controls the sorter of the conveyor system depending on the transponder information.

If only one simple evaluation of the transponder ID is required, and the data will not be processed any further, the SIMATIC RF680R provides this function without being connected to the controller.

Each item has a transponder that is always fitted at the same position and with the same alignment on the item. These transponders also contain user data that provides information about the sender and receiver of the goods. There is a separator at the end of the conveyor belt that determines the output gate to which the goods should be directed. The separator is set according to the results from the reader and the goods are distributed.

After the sorter, the goods are loaded onto pallets - each pallet is fitted with a transponder. These transponders also contain user data that provides information about the sender and receiver of the goods. Based on the data read by the SIMATIC RF650R reader, the pallets at the outgoing goods gate are checked to make sure that they are intended for the receiver to which the gate is assigned.

When several RFID readers are used, there is a danger that RFID transponders can also be read out by other readers. Care must therefore be taken to ensure that the transponder can only be identified by the intended reader.

Technical disruptions between readers then occur particularly when they transmit on the same channel (on the same frequency). You will find more detailed information in the section "The response of electromagnetic waves in the UHF band (Page 73)".

To prevent this, readers used in Europe and China must operate on different channels with "frequency hopping" activated. "Frequency hopping" is permanently set in the USA.

As a result of the large difference in level between the transmitter channels and the transponder response channels, this technology provides great advantages for frequency reuse. However, a prerequisite is that a certain minimum distance, and thus minimum decoupling, is observed between the antennas of adjacent readers.

4.3 Antenna configurations

An improvement in the tag reading accuracy in an environment with a high density of readers can be achieved by aligning the antennas toward the relevant tag field, in other words by rotating them horizontally and vertically.

In addition, the transmitter power of the readers can be reduced down to the minimum at which the tags are still just detected accurately.

This greatly reduces the probability of interference.

If several readers are to be operated simultaneously in an environment, then the following settings affect the reliability of the reader's access to transponder data:

● Electromagnetic environment (see section The response of electromagnetic waves in the UHF band (Page 73))

● Type of transponder (see section Transponder/tags (Page 333))

● Number of transponders to be detected by an antenna at a time

● Type of antenna (see section Antennas (Page 245), section Guidelines for selecting RFID

UHF antennas (Page 55), and section Planning application (Page 94))

● Transponders' distance from and orientation toward antennas (see section Transponder/tags (Page 333))

● Distances and orientation of antennas of different readers to each other

● Radiated power of antennas

The robustness of tag data accesses is improved for readers whenever distances to adjacent readers are increased, radiated power is reduced, and a channel plan (for ETSI readers) is implemented. Adjacent readers are parameterized in the channel plan such that they cannot use the same channels.

A channel plan can be created for ETSI readers; for FCC readers, it is assumed that the probability of two readers accidentally using the same channel is very low.

This technique is intended to prevent mutual interference between readers. The reader changes its transmission channel in a random or programmed sequence (FHSS).

Frequency hopping is always active with FCC. The 50 available channels mean that the probability is low that two readers will be operating on the same frequency (refer to the section Regulations for UHF frequency bands in the USA (Page 78)). In China, one reader operates on at least 2 channels, e.g. 16 channels of 2 W (refer to the section Regulations for UHF frequency bands in China (Page 76)).

Frequency hopping is optional with ETSI. According to ETSI EN 203 208 V1.2.1, frequency hopping is used in multi-channel operation. Without frequency hopping, only single channel operation is possible for which the standard specifies a pause of 100 ms after each 4 s of sending.

Before planning how to use third-party components, as the operator of a system that comprises both RF600 components and third-party components, you must comply with the safety information in Section Safety instructions for third-party antennas as well as for modifications to the RF600 system (Page 23).

In line with the application, you must take into consideration the mechanical loads (shock and vibration) as well as environmental demands such as temperature, moisture, UV radiation.

The device could be damaged if these factors are not considered.

Depending on whether you want to use a third-party antenna and/or a third-party antenna cable with an RF620R, RF630R, RF640R or RF670R reader, you need to select the suitable components. These instructions will help you to select the components and the settings of the important parameters in the RF-MANAGER Basic.

There are two different application cases:

● Selection of third-party components:

You want to select suitable third-party components for the SIMATIC RF600 system and then configure the reader for these components.

● Configuration of existing third-party components:

You already have third-party components (antennas, antenna cables or both) and want to configure the reader for these components.

Always proceed in the following order during your considerations and the practical implementation:

1. Consider which third-party components you wish to use in the SIMATIC RF600 system.

2. Depending on the third-party component required, refer either to section Antennas

(Page 58) or section Antenna cables (Page 69) for the important criteria for selection of your components. The selection criteria/parameters are sorted in descending relevance.

3. Use the specified equations to calculate your missing parameters, and check whether the

required values are reached (e.g. antenna gain) and that important secondary values (e.g. cable loss) are not exceeded or undershot.

4. Configure the reader with the parameters of your third-party components. Normally, you

can do this with the RF MANAGER Basic. Depending on the reader, the values can alternatively also be set via XML protocol or SIMATIC protocol. You will find an overview of the information for the parameter assignment of all RF600 system readers in the section Overview of parameterization of RF600 reader (Page 461).

Basically all types of directional antennas can be considered as third-party antennas for integration into the SIMATIC RF600 system. Directional antennas have a preferred direction in which more energy is radiated than in other directions.

RF600 antennas on the other hand, are optimized for operation with RF600 readers and have all the required approvals.

The properties of an antenna are determined by a large number of parameters. You must be aware of these properties in order to make the correct selection for your appropriate UHF antenna. The most important parameters are described below. These important parameters are described in detail in the following sections. The following parameters describe both the send and receive functions of the antenna (reciprocity). The antenna is a passive antenna. A two-way relationship exists.

4.3 Antenna configurations

In order to comply with national directives with regard to the radiated power (which differ depending on the location or country of use), the RF600 readers together with the antenna cable(s) and antenna(s) must be exactly parameterized or configured.

This means that the product of the transmitted power P

must always have the correct ratio with regard to the radiated power "EIRP" depending on

of the reader and the antenna gain

the location of use or the permissible frequency band.

Calculation of the radiated power is briefly described below.

The radiated power is the total power radiated by the antenna in the room. The isotropic radiator serves as the physical computing model which uniformly radiates the power into the room (spherically, i.e. isotropic).

Directional antennas combine the radiation, and therefore have a higher power density in the main beam direction compared to an isotropic radiator. To enable antennas of different design or Directional characteristic to be compared with one another, the equivalent isotropic radiated power (EIRP) has been introduced which represents the effective power which must be applied to an isotropic radiator in order to deliver the same power density in the main beam direction of the antenna.

"EIRP" is the product of the transmitted power P

EIRP = P

and the antenna gain Gi:

Also common is specification of the equivalent radiated power referred to the half-wave dipole "ERP" (effective radiated power):

Approximate calculations are easier to carry out as additions than as products, therefore the logarithms are taken for the above equations and the power data standardized to 1 mW and specified in decibels (dBm or dBi).

If the transmitted power is not applied directly but via a cable with loss aK, this loss should be compensated such that the same radiated power is obtained.

If the loss is not appropriately compensated, the radiated power is too small.

This section provides you with information on the unit "decibel". This knowledge is a requirement for optimum understanding of the following section. You can ignore this section if you already have the appropriate knowledge.

When specifying decibels, the ratios between powers or voltages are not defined directly but as logarithms. The decibel is therefore not a true unit but rather the information that the specified numerical value is the decimal logarithm of a ratio of two power or energy variables P1 and P2 of the same type.

This ratio is defined by the following equation:

The antenna gain specifies the degree to which the antenna outputs or receives its power in the preferred angle segment.

With this theoretical variable, a comparison is always made with an isotropic spherical radiator, a loss-free antenna which does not exist in reality. It describes how much power has to be added to the isotropic spherical radiator so that it outputs the same radiated power in the preferred direction like the antenna to be considered. The unit for the antenna gain is therefore specified in dBi (dB isotropic).

The antenna gain is defined for the receive case as the ratio between the power received in the main beam direction and the received power of the isotropic spherical radiator.

You must know the antenna gain in the corresponding frequency band or range. You can obtain the value of the antenna gain from the technical specifications of your antenna vendor.

● With a cable loss of 4 dB, a gain ≥ 6 dBi(L) is required since otherwise the maximum

radiated power will not be achieved.

● In the case of antennas used in the FCC area of approval, a gain of at least 6 dBi(L) is

required since otherwise the permissible radiated power of 4 W EIRP will not be reached.

● If the gain is > 6 dBi(L)*, the difference is compensated in accordance with the directives

by reducing the transmitted power.

● Frequency dependency: if a frequency dependency exists in the frequency band used, you must apply the highest value in each case for the antenna gain. With the cable loss, on the other hand, you must select the smallest value in each case it frequency dependency exists. This procedure means that the permissible radiated power will not be exceeded in the extreme case.

● Dependency on the plane If the data for the antenna gain are different in the horizontal and vertical planes, you must use the higher value in each case.

Impedance is understood as the frequency-dependent resistance. The impedances of the antenna, reader and antenna cables should always be the same. Differences in the impedance result in mismatching which in turn means that part of the applied signal is reflected again and that the antenna is not fed with the optimum power.

● Only antennas can be used whose connection has a characteristic impedance of Z = 50 Ohm.

● The mechanical design of the coaxial antenna connection is of secondary importance; N, TNC and SMA plug connectors are usual.

Since the impedance at the antenna connection is frequency-dependent, mismatching automatically occurs with broadband use. This mismatching can be reflected by two parameters:

The power sent by the transmitter cannot flow unhindered to the antenna and be radiated as a result of the mismatching described by the VSWR. Part of the power is reflected at the antenna and returns to the transmitter. The powers in the forward and reverse directions produce a standing wave which has a voltage maximum and a voltage minimum. The ratio between these two values is the VSWR (voltage standing wave ratio).

The return loss parameter is based on the reflection factor which describes the voltage ratio between the forward and reverse waves.

So that the smallest possible transmitted and received powers are reflected by the antenna under ideal conditions, you should observe the following data for the VSWR and the return loss |S

The power rating is understood as the maximum power defined by the vendor with which the device may be operated.

Third-party antennas must be dimensioned for an effective power applied to the antenna connection of at least 4 Watt.

The polarization parameter describes how the electromagnetic wave is radiated by the antenna. A distinction is made between linear and circular polarization. With linear polarization, a further distinction is made between vertical and horizontal polarization.

UHF transponders usually have a receive characteristic similar to that of a dipole antenna which is linearly polarized. Horizontal or vertical polarization is then present depending on the transponder mounting.

If the orientation of the transponder is unknown, or if an alternating orientation can be expected, the transmit and receive antennas must have circular polarization.

When selecting a circular antenna, the polarization purity must be observed in addition to the polarization direction. A differentiation is made between left-hand and right-hand circular polarization (LHCP and RHCP). The two types cannot be combined in the same system. On the other hand, selection of the polarization direction is insignificant if the antenna system of a transponder is linearly polarized. With actual antennas, elliptical polarization is encountered rather than the ideal circular polarization. A measure of this is the ratio between the large and small main axes of the ellipse, the axial ratio (AR), which is frequently specified as a logarithm.

As a result of the principle used, no special requirements need be observed to suppress the orthogonal components (cross-polarization).

Figure 4-6 Homogenous vertical polarization of antenna system and transponder

As a result of their design, directional antennas not only transmit electromagnetic waves in the main beam direction but also in other directions, particularly in the reverse direction. The largest possible suppression of these spurious lobes is expected in order to reduce faults and to keep the influence on other radio fields low. This attenuation of spurious lobes in the opposite direction to the main beam is called the front-to-back ratio.

Requirement: The front-to-back ratio must be ≥ 10 dB. This requirement also applies to spurious lobes illustrated by the following graphics in Section Half-value width (Page 66).

In ETSI EN 302 208 (release version V1.2.1 2008-06), the radiated power is coupled to the beam width, i.e.

● This antenna cable must have a nominal characteristic impedance of Z = 50 Ohm.

In order to be able to transmit the available UHF power from the RF600 reader to the antenna(s), the antenna cable loss must not exceed a value of approx. 4 dB.

You should therefore preferentially select cable with double shielding since this provides the best damping.

Bending radius of the antenna cable

Connectors and adapters

4.3 Antenna configurations

The cable loss depends on two important factors:

● External characteristics of cable. These includes the cable length, diameter and design.

● As a result of the physical principle, the cable loss is also frequency-dependent, i.e. the

cable loss increases at higher transmitter frequencies. Therefore the cable loss must be specified in the frequency band from 860 to 960 MHz.

Cable vendors usually provide tables or calculation aids for their types of cable which usually include the transmitter and receiver frequencies as well as the cable length. Therefore contact your cable vendor in order to determine the appropriate type of cable using the approximate value referred to above.

Coaxial antenna cables always have a shielded design and therefore radiate little of the transmitted power to the environment.

The properties of the cable shield are influenced by mechanical loading or bending. You must therefore observe the static and dynamic bending radii specified by the cable vendor.

You must use connectors and adapters of type "Reverse Polarity R-TNC" (male connector) for your antenna cables from a third-party supplier in order to ensure correct connection to the RF600 reader interface.

The figure below shows the standard for a suitable thread:

You can find more information in the catalog data of your cable vendor.

This section contains an example with specific values. Using this example it is possible to understand how the complete selection procedure for antennas, cables, and adapters as well as the settings could be carried out on an RF600 system reader.

In the example, it is assumed that you want to use your SIMATIC RF600 system with your third-party components in Germany (ETSI EN 302 208 V1.4.1).

1. Compare the technical specifications of your antenna with the values required by the

Since the specific VSWR value of the antenna does not agree with the value required by the system, you must have this value checked. Therefore contact your antenna vendor or an EMC laboratory.

2. Compare the technical specifications of your cables and connectors with the values

required by the system. For example, you can use cables of type "LMR-195" from the company "TIMES MICROWAVE SYSTEMS". Suitable cables have e.g. an outer diameter of 5 mm. The company offers various designs of cables depending on the requirements. Numerous connectors are also available for their cables.

4.4 Environmental conditions for transponders/tags

The transponder/tag must not be placed directly on metal surfaces or on containers of liquid. For physical reasons, a minimum distance must be maintained between the tag antenna and conductive material. A minimum distance of 5 cm is recommended. The tag operates better when the distance is greater (between 5 and 20 cm).

● Tag assembly on non-conductive material (plastic, wood) has a tendency to be less

critical than assembly even on poorly conductive material.

● The best results are achieved on the materials specified by the tag manufacturer.

● You can obtain more detailed information from the tag manufacturer.

Electromagnetic waves in the UHF band behave and propagate in a similar manner to light waves, that is they are reflected from large objects such as ceilings, floors, walls and windows and interfere with each other. Due to the nature of electromagnetic waves, interference can lead to wave amplification which can produce an increased reading range. In the worst case, interference can also result in waves being extinguished which causes holes in reader coverage.

Reflections can also be beneficial when they cause electromagnetic waves to be routed around objects to a certain extent (deflection). This can increase the reading probability.

Due to these electromagnetic characteristics, it is extremely difficult in the multiple-reflection environment that is usually found in the real environment on site, to determine propagation paths and field strengths for a particular location.

● Reducing the transmit power:

To reduce interference to a minimum, we recommend that the transmitter power of the reader is reduced until it is sufficient for an identification rate of 100%.

● Increasing the number of antennas to 3 or 4:

More antennas in a suitable antenna configuration can prevent gaps in reader coverage.

Influence of external components

4.5 The response of electromagnetic waves in the UHF band

Metal can have an effect on the electromagnetic field depending on the arrangement or environment. The effect ranges from a hardly determinable influence through to total blocking of communication. The term metal in this context also includes metallized materials that are either coated with metal or shot through with metal to such an extent that UHF radiation cannot penetrate or only to a minimal extent.

The effect of metal on the electromagnetic field can be prevented as follows:

● Do not mount tags on metal.

● Do not place metallic or conducting objects in the propagation field of the antenna and

transponder.

In general, tags must not be mounted directly onto metallic surfaces. Due to the nature of the magnetic field, a minimum distance must be maintained between the tag antenna and conductive materials. For further details on the special case of attaching transponders to electrically conducting materials, see Section SIMATIC RF620T (Page 375) and SectionSIMATIC RF640T Gen 2 (Page 418) .

In the case of transponders that are not designed for mounting on metallic materials, the minimum permissible distance from metal is 5 cm. The larger the distance between the transponder and the metallic surface, the better the function of the transponder.

Non-metallic substances can also affect the propagation of electromagnetic waves.

When non-metallic substances or objects are located in the propagation field that can absorb UHF radiation, these can alter the antenna field depending on their size and distance and can even extinguish the field entirely.

The high-frequency damping effect of water and materials with a water content, ice and carbon is high. Electromagnetic energy is partly reflected and absorbed.

Liquids and petroleum-based oils have low HF damping. Electromagnetic waves penetrate the liquid and are only slightly weakened.

The R&TTE guideline and the relevant standards govern the electromagnetic compatibility requirements. This also concerns the external components of the RF600 system. Even though the requirements for electromagnetic compatibility have been specified, various components will still interfere with each other.

The performance of the RF600 system is highly dependent on the electromagnetic environment of the antennas.

Overview of the frequency bands

4.6 Regulations applicable to frequency bands

On the one hand, antenna fields will be weakened by absorbing materials and reflected by conducting materials. When electromagnetic fields are reflected, the antenna field and reflecting fields overlap (interference).

On the other hand, external components can transmit on the same frequency band as the reader. Or the external components can transmit in different frequency bands with side bands that overlap with the frequency band of the reader. This results in a reduction of the "signal-to-noise" ratio which reduces the performance of an RF600 system.

If a DECT station that is transmitting in the 2 GHz band, for example, is located in the receiving range of an antenna of the RF600 system, the performance of the write and read accesses to the transponder will be affected.

EMC can be broken down into three different areas:

● Immunity to external interference: immunity to external electromagnetic disturbance

● Degree of interference emission: emission of interference and its effect on the electrical environment

All three areas are considered when testing an electrical device.

The RFID modules are tested for conformity with the limit values required by the CE and RTTE guidelines. Since the RFID modules are merely components of an overall system, and sources of interference can arise as a result of combining different components, certain guidelines have to be followed when setting up a plant.

EMC measures usually consist of a complete package of measures, all of which need to be implemented in order to ensure that the plant is immune to interference.

It is often sufficient to follow a few elementary rules in order to ensure electromagnetic compatiblity (EMC).

The following rules must be observed:

● Protect the device against external interference by installing it in a cabinet or housing. The housing or enclosure must be connected to the chassis ground.

● Use metal plates to shield against electromagnetic fields generated by inductances.

● Use metal connector housings to shield data conductors.

● Coupling path

● Interference sink

If one of the components is missing, e.g. the coupling path between the interference source and the interference sink, the interference sink is unaffected, even if the interference source is transmitting a high level of noise.

The EMC measures are applied to all three components, in order to prevent malfunctions due to interference. When setting up a plant, the manufacturer must take all possible measures in order to prevent the occurrence of interference sources:

● Only devices fulfilling limit class A of VDE 0871 may be used in a plant.

● Interference suppression measures must be introduced on all interference-emitting

devices. This includes all coils and windings.

● The design of the system must be such that mutual interference between individual components is precluded or kept as small as possible.

Information and tips for plant design are given in the following sections.

In order to achieve a high level of electromagnetic compatibility and thus a very low level of disturbance in a plant, it is necessary to recognize the most frequent interference sources. These must then be eliminated by appropriate measures.

Figure 4-8 Equipotential bonding (EBS = Equipotential bonding strip)

The better the equipotential bonding in a plant, the smaller the chance of interference due to fluctuations in potential.

Equipotential bonding should not be confused with protective earthing of a plant. Protective earthing prevents the occurrence of excessive shock voltages in the event of equipment faults whereas equipotential bonding prevents the occurrence of differences in potential.

Signal cables must be shielded in order to prevent coupling of interference.

The best shielding is achieved by installing the cables in steel tubes. However, this is only necessary if the signal cable is routed through an environment prone to particular interference. It is usually adequate to use cables with braided shields. In either case, however, correct connection is vital for effective shielding.

The RF620R can be electrically connected to the ground potential through a contact washer. The tightening torque must be increased in this case to ensure that electrical contact is made (2.7 Nm).

(d) Contact washer:

Use contact washers according to the Siemens standard SN 70093-6-FSt-flNnnc480h for ground connection, Siemens item No.: H70093-A60-Z3

The RF620R has a circular polarized antenna. At 500 mW ERP radiated power, due to the opening angle of the antennas, their fields can overlap considerably. It is no longer possible to clarify in which antenna field access to the data of a tag is performed.

In order to avoid this, always keep a minimum distance of 3 m between two readers with the maximum radiated power of 500 mW ERP.

The readers can also interfere with each other (secondary fields), if the channels (Reader TX, Transponder TX) overlap. In order to prevent a transponder channel overlapping with a reader channel, we recommend that the Dense Reader Mode (DRM) is used.
