OEM DESIGN CONSIDERATIONS When integrating the NUR-0W1 module into host board you need to follow the below recommendations to obtain proper operation of the module. 4.1. RF-OUTPUT AND ANTENNA REQUIREMENTS For UHF RFID module it is very important that good RF design practices are used. Unlike conventional radios, transmission and receiving are on at the same time without significant frequency separation. This leads to situation where systems reflective power coming back to modules RF pin will decrease the performance of the module. Less reflective power means better performance and vice versa. 4.1.1. ANTENNA CONSIDERATIONS Like stated earlier, minimising the reflective power is the key to good performance. Main source for this power is antenna having a poor S11 (reflection attenuation) value. If matching of the antenna is poor, significant part of the RF power will not radiate but instead will reflect to the module. Antenna should have S11 value equal or better than 10dB. 4.1.2. LAYOUT RECOMMENDATIONS RF output must be routed using 50ohm transmission line (see section 4.1.3). If proper RF design guidelines are not used it might lead to decrease of output power, sensitivity and cause mask violations. 4.1.3. TRANSMISSION LINE The RF signal from the module is routed to antenna connector using a grounded CPW structure. This is to achieve the maximum isolation and RF shielding to RF lines. Also, grounding bias should be added along the line to give additional shielding. Figure 4. Grounded CPW with via stitching. Table 7. Recommended PCB values for 4-layer board (L2 is the GND plane for transmission line)

Q-VALUE The Q-value defines the amount of open response slots that tags can use per one inventory round. Number of slots can be calculated by formula 2Q. It is advised to use twice as much slots compared to amount of tags that you have in your readers reading field simultaneously. Selectable values are 0 – 15 and value 0 means automatic Q-value adjustment. When q value of 0 is used, reader will automatically increase the Q-value when lots of collisions are noticed and decreased the value when there are only few collisions. By default, the Q-value is set to 0. Table 9. Relation between the Q value and the number of response slots for round. Q-value Response slots Q-value Response slots 0 Automatic 8 256 1 2 9 512 2 4 10 1024 3 8 11 2048 4 16 12 4096 5 32 13 8192 6 64 14 16384 7 128 15 32768 6.2. SESSION There are four session options which you can use when initializing inventory round. Every session has two target states A and B. By default, Gen2 tags are at state A if tag has not been read recently. When tag is read it flips to state B and doesn’t reply to readers query made using target state A. The table below describes the persistence of tag’s state machine when using different session values. For example, when using session 0 the tag will come back to state A immediately when tag power is lost. Usually tag loses the power when reader stops the inventory round or chances the channel. Persistence when tag power is ON is not defined by the ISO18000-6C when using session settings S0, S2 and S3. With session 1 the tag will keep it state over 500ms but less than 5s. With session values 2 and 3 tags will keep it states over 2s when tag power is lost. Time can vary depending what tag IC is used. Table 10. Persistence characteristics of gen2 tags.

ROUNDS The rounds setting defines how many query rounds is done inside one inventory round. After every inventory round the reader will send data to the Host. Selectable values are 0 – 10. Zero meaning automatic rounds adjustment. The automatic adjustment decides after every query round whether another round is necessary based on the number of data collisions. By default, rounds setting is set to 0. This setting can help the reader to find all the tags that are in the readers reading field when using session 0. Because tags that are found in query round 1 doesn’t replay in the following query rounds. When using session 1/2/3 this does not make any significant difference because tags that are read are quiet anyway. Table 11. Relation between inventory round and query round. Inventory round Query round 1 Query round 2 Query round 3 … Query round 10 6.4. SELECTING RIGHT PARAMETERS TBD 6.5. RSSI-FILTERS NUR-0W1 module has internal RSSI filters which can be used to limit the read area. By applying the filters, you can set the limits which tag replay must met to be registered. MIN RSSI –value means that tag replay signal needs to be equal or stronger then the defined value. Otherwise tag is not read. MAX RSSI value in other hand means that signal strength must be lower than the filter value. There are separate RSSI filter values for inventory, read and write operations. These can be set individually.

Read range limited by the RSSI filter (100mW TX power level and 0dBi antenna gain used). 6.6. DYNAMIC POWER SAVE MODE NUR-0W1 module has power save modes which can be enabled via SW API. By default, the power save is ON with depth of 100ms. Other depths are 500ms and 1000ms. The power save mode works in a way that when module reads continuously (applies only when using inventory stream -command) it goes to sleep if there are no tags in the field. The sleep time is defined by the depth value. After the sleep period is elapsed module starts to read again and so on. If there are one or more tags in the field the module will not go into sleep 7. GPIO CONFIGURATIONS All GPIOs can be configured via SW API to be inputs or outputs. IO voltage level is 3.3V and maximum source current is 4mA and sink current 4mA. When configured as input SW API can check what the state (high / low) of the GPIO pin is. Also, event is generated from the state change. When GPIO is configured as an output the SW API can drive the GPIO pin to high or low. 8. DIAGNOSTIC FUNCTIONS Using diagnostic functionalities like channel channer, reflected power measurement and received signal level indicator you can examine the proper operation of the module.

Nordic ID Group | Joensuunkatu 7 | FI-24100 Salo |Finland Office +358 2 727 7700 | Fax + 358 2 727 7720 | info@nordicid.com www.nordicid.com | www.rfidarena.com 2019-03-08 NUR-0W1 HW implementation guide CONFIDENTIAL Version 1.0 8.1. CHANNEL SCANNER TBD 8.2. REFLECTED POWER MEASUREMENT This measurement can be used to check what is the matching of the antenna(s) and feed line(s). When this function is triggered will NUR-0W1 module set a carrier wave ON at full power and then measure the power level which is coming to receiver port. To transform the returned value into absolute power level coming in to modules RF-pin, you need to add 13 to the obtained value. Using this functionality, you can verify is the antenna connected and what is the frequency where the best matching of the antenna is located. 8.3. RECEIVED SIGNAL STRENGTH INDICATOR (RSSI) When reading a tag NUR-0W1 module also returns received signal strength indication values. Two values are returned per one tag. One is the absolute power level (dBm) and second is the scaled RSSI value of the tags backscatter signal. Scaled RSSI value returned is between 0 – 100. 0 being the minimum signal level the module can receive and 100 as a maximum. 9.

The transmitter module must not be co-located with any other transmitter, except with those that are within the limits shown in the NUR-0W1 filing. 2. The transmitter module can only be used with a host antenna circuit trace layout design in strict compliance with the OEM instructions provided. When the conditions above are met, typically no radio transmitter testing of NUR-0W1 is required. However, the OEM integrators have responsibility for testing their end-product for other compliance requirements, for example digital device emissions, PC peripheral requirements. Note: In the event that these conditions can’t be met (for certain configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can’t be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the host product (including the transmitter) and obtaining a separate FCC authorization. The OEM integrator must be aware not to provide information to the end user regarding how to install or remove this RF module in the user manual of the host product. In case that OEM integrator / host product manufacturer that integrate NUR-0W1 module into their product and would like change defined parameters of the antenna trace as instructed in this document, they must notify Nordic ID for further instructions. In this case, either Nordic ID can make class 2 permissive change or OEM integrator / host product manufacturer can make change in id procedure (new application) followed by a class 2 permissive change application. If host product manufacturer / OEM integrator is responsible of external antenna connector for their product, they must contact Nordic ID for further instructions. Nordic ID will provide list of acceptable unique connectors that must be used.
