1 Scope This document describes details about the individual application and test set-ups. It covers the

description of the set-ups including the purposes of the tests, guidelines for preparations, and

guidelines for conducting the tests.

The Plugtests™ Event will be supervised by ETSI (Electronic Telecommunication Standardization

Institute), CESI (China Electronics Standardization Institution) and CPST (China Post Science & Technology) at sites of CESI and CPST.

2 Introduction The present document is one of a set of two that describes a series of interoperability tests to be performed at CPST. It specifies the set-up requirements for each of the scenarios and describes

the test procedures as well as analysis of the results. For details of the administrative and

logistical arrangements for the tests, the reader should refer to the event web-page [7].

A total of seven separate tests are described. The first three take the form of pre-tests that should be carried out in advance of the main tests. The remaining four tests are referred to as

application scenarios.

The three pre-tests are designed to verify the satisfactory performance of each of the interrogators provided by the different vendors. These tests include a check that the emissions

from interrogators conform to a specified spectrum mask and validation that the interrogators are compatible when operated simultaneously in the same geographic space. Furthermore, one of

the pre-tests is designed to verify the use of the four-channel plan in China.

The four test scenarios are representative of typical applications at CPST. A description is given for each scenario of the required configuration including, as appropriate, portals, conveyors, roll

cages, carts and the attachment of tags. In addition the positions of the antennas are defined.

Tags will be supplied by different vendors and be of different types. All tags used in the scenarios

will be attached to items prior to the tests. The ID of each tag together with its position and type

should be recorded.

The test procedure for each scenario is specified in detail on a step-by-step basis. Each of the

supplied interrogators will be tested in turn at each of the scenarios. The results of all tests will be logged and analysed. The results will show any variations in performance between the

different interrogators and whether there are any incompatibilities between interrogators and the

different types of tags.

4 Pre-test 1: DRM spectrum mask

4.1 Test Description Identifier TD_PREMAIL_1 In these preliminary tests the intentional emissions from interrogators, shall be set to their maximum permitted output level and shall be measured using a spectrum analyser. For a

specification of the spectrum analyser see Annex E.

4.2 Summary The purpose of the tests described in this subsection is to verify whether the spectrum emissions of the provided RFID interrogators comply with the ISO/IEC 18000-6REV1 standard [3].

4.3 Configuration The interrogator output shall be connected to a spectrum analyzer. It shall be noted that

appropriate attenuators1 shall be used in order to protect the spectrum analyzer input.

4.4 Pre-test Condition There is no special pre-test conditioning.

4.5 Test Sequence The test shall cover the measurement as described in [3] clause 9.3.1.2.11 "Transmit mask" for

dense-interrogator.

1.) Setup interrogator and spectrum analyzer.

2.) Setup the interrogator to continuously send a modulated carrier at fc = 921.125 MHz with a power of 27 dBm (as this would be a setting where a typical 6 dB antenna would

deliver 33 dBm ERP). The measurements should be adjusted to compensate for the

cable loss of the cables used in the tests.

1 One 10 dB and one 20 dB attenuator will be provided by CESI.


5

3.) Measure the integrated power for a 2.5/Tari bandwidth RBW centred at fc, an offset

frequency fo = 2.5/Tari, and a 2.5/Tari bandwidth SBW centred at (n × fo) + fc (integer n).

4.) The ratio of the integrated power P() in SBW to that in RBW with the Interrogator

transmitting random data2 shall not exceed the specified values:

|n| =1:10log10(P(SBW)/P(RBW)) < –30 dBch

|n| = 2: 10log10(P(SBW) / P(RBW)) < –60 dBch

|n| > 2: 10log10(P(SBW) / P(RBW)) < –65 dBch

Where P() denotes the total integrated power in the 2.5/Tari reference bandwidth.

This mask is shown graphically in figure 1, with dBch defined as dB referenced to the integrated power in the reference channel.

5.) Any anomalies in the results will be recorded

2 Random data may be done through anti-collision and identification commands as required. For ISO/IEC 18000-6C this would be

e.g. Select, Query, Query_Rep, Query_Adjust, ACK, NAK. For ISO/IEC18000-6TOTAL this would mean no data, as there is no forward link specified.

5 Pre-test 2: Multi-interrogator environment

5.1 Test Description Identifier TD_PREMAIL_2

5.2 Summary These tests shall cover the simultaneous operation of all participating interrogators, which shall

be located in close proximity to each other. Each interrogator shall continuously identify 30 tags.

In order to increase the challenge each interrogator may only select between 2 channels with

centre spacing of Test a) 500 kHz and Test b) 1 MHz.

5.3 Configuration For the test setup all interrogators participating in the whole tests shall be setup in a wide circle

and the antennas facing outwards of the circle. The antennas should be positioned 1 m above

the ground and directed outwards. Figure 2 shows an illustrative example but with the antenna

only placed 10 cm above ground.


7

Each interrogator shall have 30 tags of the same protocol type 3(i.e. ISO/IEC 18000-6B, ISO/IEC

18000-6C or ISO/IEC 18000-6TOTAL) positioned randomly within the beamwidth of the antenna at distances of less than 3 m. Figure 2 shows an illustrative example with a smaller number of

tags.

The spacing between interrogators shall ensure that no interrogator reads tags associated with another interrogator. Depending on the tag performance this will require a spacing between

interrogators of at least 7 m.

Figure 2: Setup illustration – illustrative example of setup

Figure 3: Setup illustration – example of setup

5.4 Pre-test Condition Each interrogator shall be turned on alone and shall be able to detect the 30 tags in its vicinity,

but not any other tags. Interrogators shall be numbered sequentially around the circle. Each

interrogator with an odd number shall be set initially to a fixed carrier frequency of 920,625 MHz and those with even number shall be set to 921,625 MHz. All interrogators shall be configured to

operate in the inventory mode.


9

5.5 Test Sequence 1.) Set radiated power of interrogators to 33dBm ERP (Note: might be reduced to 27dBm in

case of physical space limitations).

2.) Turn on interrogator sequentially in the sequence 1, 2, …, n. Note detection rate each

time a new interrogator is turned on.

3.) Repeat step 1 starting with interrogator 2 and turning on the other interrogators in sequence. Repeat this same process for the remaining interrogators. In case the

performance of the overall interrogator setup decreases when a particular interrogator is

turned on, then this shall be recorded.

4.) The test shall be repeated with odd number interrogators set to a fixed carrier frequency

of 921,125 MHz and those with even number shall be set to 921,625 MHz.

The final test report shall cover a list of problematic interrogators. Such issues are usually due to

out-of channel and spurious emissions that meet the requirements for the spectrum masks for

regulations and dense-interrogator operation, however, exceed the limits required for RFID

applications.

The final test report shall also record the behaviour of TOTAL tags in mixed environments.

For the test the number of identified tags and the time to identify those tags (all tags?) shall be

recorded.

6 Pre-test 3: Four channel plan

6.1 Test Description Identifier TD_PREMAIL_3

6.2 Summary These tests shall cover the simultaneous operation of all participating interrogators, which shall be located in close proximity to each other. Each of the at least 4 interrogators shall continuously

identify 30 tags. In order to increase the challenge each interrogator may only select between 2

channels with centre spacing of 1200 kHz according the European 4-channel plan as described in ETSI EN 302 208 and CEPT REC 70-03 Annex 11. The channel for operation shall be channels 4

and 7.

6.3 Configuration For the test setup all interrogators participating in the whole tests shall be setup in a wide circle and the antennas facing outwards of the circle. The antennas should be positioned 1 m above

the ground and directed outwards. Figure 2 shows an illustrative example but with the antenna

only placed 10 cm above ground.


10

Each interrogator shall have 30 tags of the same protocol type 4(i.e. ISO/IEC 18000-6B, ISO/IEC

18000-6C or ISO/IEC 18000-6TOTAL) positioned randomly within the beamwidth of the antenna at distances of less than 3 m. Figure 2 shows an illustrative example with a smaller number of

tags.

The spacing between interrogators shall ensure that no interrogator reads tags associated with another interrogator. Depending on the tag performance this will require a spacing between

interrogators of at least 7 m.

6.4 Pre-test Condition Each interrogator shall be turned on alone and shall be able to detect the 30 tags in its vicinity,

but not any other tags. Interrogators shall be numbered sequentially around the circle. Each

interrogator with an odd number shall be set initially to a fixed carrier frequency of 865.7 MHz

and those with even number shall be set to 866.9 MHz. All interrogators shall be configured to

operate in the inventory mode.

6.5 Test Sequence 1.) Set radiated power of interrogators to 33dBm ERP (Note: might be reduced to 27dBm in

case of physical space limitations).

2.) Turn on interrogator sequentially in the sequence 1, 2, …, n. Note detection rate each

time a new interrogator is turned on.

3.) Repeat step 1 starting with interrogator 2 and turning on the other interrogators in

sequence. Repeat this same process for the remaining interrogators. In case the

performance of the overall interrogator setup decreases when a particular interrogator is turned on, then this shall be recorded.

The final test report shall cover a list of problematic interrogators. Such issues are usually due to out-of channel and spurious emissions that meet the requirements for the spectrum masks for

regulations and dense-interrogator operation, however, exceed the limits required for RFID

applications.

The final test report shall also record the behaviour of TOTAL tags in mixed environments.

For the test the number of identified tags and the time to identify those tags (all tags?) shall be recorded.

7 Application Set-up

7.1 Introduction The tests under the scope of this document generally may be split into two application set-ups. These set-ups are described in the following subsections.

7.2 Application Set-up 1: Dock Door Portal

7.2.1 Configuration

The dock door portal is used for manual movement tests. The dock door portal set-up basically comprises a dock door portal frame fitted with four antennas. Two antennas are mounted on the

horizontal member of the frame with the antenna parallel to and facing the floor. One antenna is

attached to each of the vertical columns of the portal. Each of these antennas is mounted at the

same height and facing inwards. Each interrogator under test is connected in turn to the antennas for the purpose of verifying satisfactory operation of the configurations. The test

scenarios using the dock door portal are:

• Mail Container (see TD_MAIL_1)

• Mail Case on a Cart (see TD_MAIL_2)

For all mail container tests only one pre selected antenna mounted on the horizontal member is

connected to the interrogator as described in sections 5. For all mail cases on a cart tests all four

antennas are connected to the interrogator as described in sections 6.

The portal including the antennas5 will be made available by CPST. The interrogators shall be

provided by the participating interrogator vendors (one per vendor). The tags shall be provided

by the participating tag vendors6. To eliminate one variable the same tags should be used with

all interrogators.

5 The use of antennas provided by the vendors shall be avoided unless the interrogator cannot use the provided antennas

at all.

6 ETSI will select the tags from the set of provided tags as required for the individual tests, considering that all interrogators see the same type of tags for a particular application test. Test types may vary between different application based on availability and requirements for the application (e.g. metal tags for metal environment and simple inlays for letter environment)

be recorded during the tests. See Annex C for antenna specifications.

7.2.3.1 Feeder Cables

CESI will provide cables (cable loss is 0.5 dB/m) with a length of 6 m for connection of the

antennas and interrogators. The cables will be equipped with TNC connectors.


14

7.3 Application Set-up 2: Conveyor Portal

7.3.1 Configuration

The test application conveyor is used for two tests. The conveyor set-up basically comprises a

portal frame over a steel bedded conveyor with a steel reinforced belt with interlacing. Three

antennas in total are mounted on the portal frame. One antenna is mounted to the horizontal

member of the frame position with the antenna facing to the floor at an angle of 45 degrees. One

antenna is attached to each of the vertical columns of the portal facing inside the portal. The two test scenarios sharing the conveyor portal are:

• Mail case (see TD_MAIL_3)

• Mail bag (see TD_MAIL_4)

For all mail case tests only one antenna mounted on the horizontal member is connected to the

interrogator as described in sections 9. For all mail bag tests all three antennas are connected to the interrogator as described in sections 10.

The portal and the antennas mounted on the portal over the conveyor will be made available by CPST. The interrogators shall be provided by the participating interrogator vendors (one per

vendor). The tags shall be provided by the participating tag vendors and attached in advance of the Plugtests event.

8 Tests with Mail Container

8.1 Test Description Identifier TD_MAIL_1

8.2 Summary

Figure 7: Portal - Mail Container Application Setup

The purpose of the tests described in this subsection is to verify that there is a satisfactory level

of interoperability between different tags and interrogators supplied by different vendors when

used in a typical mail container scenario (see Figure 7). Further this test is designed to verify the interoperability of tags from different technology providers with a variety of interrogators


20

operating protocols matching the tag and provided by a number of different vendors. The test

excludes an interference test of mixed protocol tags with different interrogators.

In the tests, a mail container is manually moved through a dock door portal. The container has a

tag optimized for metal on its topside. There are four antennas, two mounted on the upper side of the door portal and one mounted on each of the vertical columns as described in section 4,

however only one of the overhead antennas is pre selected for use in this test. The tag is

identified by the interrogator connected to one of the portal antennas mounted on the horizontal overhead frame.

8.3 Configuration The container shall be prepared in advance by CESI.

Table 3 summarises the application parameters for the container application set-up. Table 4

summarises the corresponding protocol parameters.

9 Tests with Mail Cases on Cart


9.2 Summary

Figure 8: Portal - Mail Cases on Cart Application S etup


of interoperability between tags and interrogators supplied by different vendors when used with typical mail cases in the cart scenario (see Figure 8).

The mail case tests include interference tests, which simulate the future likelihood of additional tags within mail items or attached to mail items being of a protocol not matching the protocol of

the interrogator under test. The simulation is limited to passive UHF RFID system components

from participating vendors only and does not seek to include the current active tags used in International mail performance monitoring. It is impossible to predict the quantity of tags, which

may be enclosed within or applied to mail items in the future. The interference test is focused


25

upon identifying the possible effects of multiple protocols on the read performance of different

interrogators.

In the tests, carts are manually moved through a dock door portal. Each cart includes sixty

tagged small mail cases. For all tests there are thirty tagged mail cases on each side of the mail cart. On each side of the mail cart the mail cases are stacked in five columns with each column

being six cases high. Four antennas are arranged around the portal and all are connected to the

interrogator under test. All tags matching the interrogator’s protocol shall be identified by the interrogator connected to the portal’s antennas. However the test objective will be to identify

each and every mail case tagged with a tag matching the protocol of the interrogator.

Tests commence with a cart containing tagged mail cases where all tags match the protocol of

the interrogator. For this test each mail case has two tags, one applied to each of the shorter sides of the small mail cases at a predefined location.

Interference tests involve mixing the population of tagged cases so that each case has two tags

matching the interrogator’s protocol and two tags not matching the interrogator’s protocol. The number of tests will be determined by the number of different tag types.

9.3 Configuration The carts and mail cases shall be prepared in advance by CPST.

There will be at least three carts each with 60 small mail cases of different combinations of tag

populations (basically tags from different vendors / of different type). With the exception that

different tags are attached to the cases, all carts and case positions shall be identical. The 60 mail cases shall include material typical for the application. Tags will be applied in advance of the

tests, one to each of the shorter sides of the mail cases. Details are given in section 8.4.

Prior to the Plugtests CPST should attach the tags, as specified, to each of the cases. They should

record details of the cart number, the case number together with the IDs of its tags and the

location of each case on the cart. CPST should confirm that all tags on all carts have been tested and are operational.

Table 5 summarises the application parameters for the mail cases on the cart application set-up.

Table 6 summarises the corresponding protocol parameters.

9.4 Pre-test Condition Mail cases on cart: Provided by CPST. The carts for testing are prepared prior to the tests.

With the exception that different tags are attached to cases, all carts are identical. The carts shall

each carry sixty tagged cases. All cases have at least one of their sides visible. Two carts each

with sixty tagged cases having one tag on each of the cases shorter sides (one hundred and twenty tags in total) shall be prepared for each tag type. The placement of tags shall be as

indicated in Figure 12 (see Rafsec tag). The arrangement of cases on carts shall be predefined

(CESI/CPST know-how).

Each interrogator set-up for testing shall complete all selected tag tests at the Dock Door Portal

before moving on to test the next interrogator. The tests shall involve each loaded mail cart passing through the portal five times. The direction of the cart shall alternate representative of a

full cart leaving and entering a facility. Of the five tests this provides three passes in one direction and two in the opposite direction. On each pass a unique electronic record of the test shall be

created.

All mail cases with homogenous populations of tags matching with the interrogator protocol shall be tested sequentially. Subsequently mail carts with mail cases having tags of different protocols



28

shall be tested to verify that only those tags are read with the interrogator’s protocol. The mixed

tag population simulates several scenarios, the most interesting of which is the instance of mail cases containing mail with tags of protocols not matching that of the interrogator.

11 Conveyor Tests with Mail Bags


11.2 Summary

Figure 18: Conveyor - Mail Bags


of interoperability between tags and interrogators supplied by different vendors when used with

typical mailbags in conveyor scenarios.

In the tests, tagged mailbags (one tag per case) filled with typical items will be moved past a

reading point (antenna arrangement) mounted on a conveyor belt (see Figure 18). The tags shall be identified by an interrogator connected to the antenna arrangement.


41

This test does not include an interference test. This is because the interference tests have

already been completed with the mail cases and because this test focuses upon random tag orientations with respect to interrogator antennas.

11.3 Configuration A number of tagged bags containing typical items shall be placed on the conveyor belt.

The bags shall be filled with typical items and will be made available by CESI (prepared in advance - see section 8.3).

Annex A Influences on Tag/Tag Interrogator Interoperability

A.1 Introduction

The main factors influencing tag interoperability are the application scenario, protocol parameters, and individual tag characteristics. Each of these factors is addressed in detail in the

following sub-sections However due to the large number of variables associated with application

scenarios and protocol parameters, it is only possible to cover the main factors influencing tag behaviour. Since there could be issues in assigning interrogator related characteristics either to

the application scenario or to the protocol parameters, the following convention is adopted. Software definable characteristics are assigned to the protocol parameters while all

others are assigned to the application scenario.

A.2 Application Scenario

The application scenario describes the set-up in which an RFID interrogator and tags are used.

The main characteristics of an application scenario include:

• Environment

o All aspects that have a certain influence on an application but are not part of the

application itself (like surrounding material, noise sources of any kind e.g. mobile phones)

• Interrogator antenna arrangement

o Position and orientation of the interrogator antennas in a set-up

o Number of interrogator antennas

o Type of interrogator antennas

• Tag arrangement

o Position and orientation of the tags in a set-up

o Number of tags

o Type of tags (different vendors/models)

• Relative movement between interrogator antennas and tags

o Speed

o Path


52

� E.g. pallet moving through portal (tags moving)

� E.g. handheld interrogator (interrogator antenna moving)

• Pallet / Case / Item characteristics

o Materials

o Arrangement

A.3 Protocol Parameters

The protocol parameters describe the protocol settings, as well as other software options

associated with a particular application set-up. The main protocol parameters are (C1G2 specific

where applicable):

• Link rates

o Forward link

o Return link

• Modulation/Encoding

o Modulation type (forward link)

o Modulation depth (forward link)

o Duty cycle (forward link)

o Encoding (return link)

• CW

o Power

o Frequency

• Link timing

o In most cases not selectable!

• Protocol flow

o Command sequence

o Collision-arbitration concept (Q protocol)

o Function

� Selection/inventory only


53

� Access - write

• Session usage

o Session flag

o Selected flag

o A � B, B � A inventory

• TRext usage

o Pilot tone

o No pilot tone

• Interrogator antenna switching (might differ for TOTAL)

o Sequence

o Timing

o Interrelation with protocol concepts (e.g. inventory round)

A.4 Individual Tag Characteristics

The individual tag characteristics describe attributes that, due to variations between different

tags, may influence tag interoperability. Some of these attributes are defined for the RFID Plugtests event and assume tags operating under ISO/IEC 18000-6B/C/TOTAL.

• Read range

o The sensitivity of a tag typically expressed as forward link range for a given transmit level.

• Orientation tolerance

o The sensitivity of a tag in terms of its read range if it is rotated away from its

preferred orientation.

• Frequency tolerance

o The sensitivity of a tag in terms of its read range at various carrier frequencies

from 860 MHz to 960 MHz.

o Tags with high frequency tolerance typically show less variation in sensitivity if

attached to different materials.

• Interference tolerance


54

o Describes the degradation in read range of tags from interference generated by

other nearby interrogators (e.g. dense interrogator environment).

• Backscatter range

o The strength of a backscatter response from a tag for a given downlink field level

in terms of return link range.

o The range of the return link for passive tags typically is greater than the range of

the forward link.

o The efficiency of the hardware design for generating the backscatter signal.

• Backscatter timing

o The interval between the instant that the interrogator ceases transmitting its

modulated signal and the instant that the tag starts to transmit its backscatter response.

• Tag proximity

o Describes the degradation in read range of a tag when positioned in proximity to

another tag / other tags.

o Detuning immunity

o Mutual coupling

• Tag flags persistence time

o Persistence time of the S1, S2, S3 and SL flags

• Tag RNG probability

o Probability of a tag’s RNG to roll a 1 in a specific time slot

Annex D General equipment specifications

D.1 Power supply

As the tests will be done in China all equipment shall be suitable for power supply with

220 V / 50 Hz for the following main power plug:

Most wall outlets simultaneously support Types A, I, and C. Some outlets support both Type A

and Type C (the holes in the outlets are flat in the middle and round on the sides) so that either

a Type A or a Type C plug can be used. The Type I outlet is next to the Type A & C outlet. Type

A outlets only fit plugs with pins of the same width -- a polarized Type A plug requires an

adapter. NOTE: no matter the type of plug the socket will accept, voltage in China is always 220 volts, 50Hz.
