2013‐09‐27 NUR‐05WL2 Implementation Guide v1.1 4 OEM DESIGN CONSIDERATIONS 4.1 RF OUTPUT AND ANTENNA REQUIREMENTS The RF output / input impedance is 50Ω so the trace leaving from the RF_OUT pin shall be kept in that same impedance level to avoid reflections and mismatch of the RF signal. To provide an appropriate impedance match place the matching components close to RF_OUT pin. Below there is the circuit diagram that shall be utilized in the fine‐tuning of the impedance match and in the additional filtering. From the RFID reader module’s point of view it is important that the used antenna has a low VSWR value. The VSWR shall be better than 1.5:1 in order to avoid decrease in the sensitivity performance of the receiver because of the TX power reflecting back from the antenna. In the NUR‐05WL2 module, there is also an ...

2013‐09‐27 NUR‐05WL2 Implementation Guide v1.1 5 RF PARAMETERS 5.1 TX LEVEL The maximum output power is +27dBm (500mW). The power can be adjusted by 1dB steps. In total there are 19 steps meaning the minimum output power value is +8dBm that equals to 6mW of power. When using higher output power levels the antennas VSWR value becomes more and more important factor. High output power combined together with antenna with poor VSWR leads to a situation where significant portion of the power is reflected back to the receiver. ...
2013‐09‐27 NUR‐05WL2 Implementation Guide v1.1 tuning does not match the RF_OUT with an antenna so the good VSWR (return loss) of the antenna is an essential factor of the good performance of the system. 5.4 MODULATION It is possible to use ASK (amplitude shift keying) or PR‐ASK (phase reversed amplitude shift keying) modulation. Tags that are compliant with ISO18000‐6C (EPC C1G2) must support both of these modulations. The PR‐ASK modulation can transfer energy more efficiently to the tag because RF envelope is ...
2013‐09‐27 NUR‐05WL2 Implementation Guide v1.1 Like stated above the Miller sub‐carrier encoding scheme affects also tag to reader data rate. In practice the Miller encoding value affects the number of clock cycles that tag uses to modulate one symbol. So when using higher Miller encoding schemes tag to reader data rate will be slower but at the same time it is more robust to interferences. Also tags response spectrum is more concentrated around the link frequency when using higher Miller schemes. This allows the receiver to use narrower channel filters. Selectable values are M2, M4, M8 or FM0. Receiver filters are optimized for M4 and M8 encoding schemes. When operating on DRM mode values 4 or 8 should be used to optimize the performance. By default Miller 4 is used. In addition to miller schemes also FM0 encoding is supported. In this case link frequency directly determines the tag to reader data rate. Table describing different data rates. Link frequency (kHz) RX encoding Tag to reader data rate (kbps) 160 FM0 160 160 M2 80 160 M4 40 160 M8 20 256 FM0 256 256 M2 128 256 M4 64 256 M8 ...

2013‐09‐27 NUR‐05WL2 Implementation Guide v1.1 6 READING PARAMETERS 6.1 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 2 . 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=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 indicating the relation between the Q‐value and the number of open slots per round. Q‐value slots Q‐value slots 0 automatic 8 256 1 2 9 512 2 4 10 1024 3 8 11 2048 4 16 12 ...

This would happen if tags would have been read recently using Session 1 2 or 3. NUR‐05WL2 module also supports dual target mode. In that mode reader will change the target mode between inventory rounds. By default target mode A is used. 6.3 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 ...

2013‐09‐27 NUR‐05WL2 Implementation Guide v1.1 Besides Q‐value one important parameter is session. In general it could be stated that if the size of tag population is measured in thousands rather than in hundreds it is wise to use sessions 2 or 3. Because then every tag will be read only once and that makes large tag population much faster and easier to read. When using session 2 or 3 it is advised to use Miller 8 encoding scheme to avoid data transfer errors as much as possible. Rounds 1 setting is also advised to be used with session 1 or 2 or 3. With session 0 it might be useful to use higher rounds value than 1 to be able to find all the individual tags. By default automatic (0) rounds setting is used. Other settings like modulation, link frequency and RX‐encoding has a minor impact to the reading speed of the reader. When operating in optimal environment following will apply: RX encoding: FM0 is fastest but quite sensitive to interferences / M8 slowest but very robust Modulation: No effect to speed but PR‐ASK has better range with some tags Link frequency: 320 kHz is the fastest / 160 kHz is the slowest Guideline settings to be used with different tag populations. Settings Tag population Simultaneously in the field ...

2013‐09‐27 NUR‐05WL2 Implementation Guide v1.1 The antenna used with the NUR‐05WL2 transmitter module can have a gain of 8 dBi at the maximum. Higher gain antennas may be used if cable loss compensates the exceeded antenna gain. For example 2dB antenna cable loss reduces EIRP so that 10dBi antenna may be used. 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 reevaluating the end product (including the transmitter) and obtaining a separate FCC authorization. The OEM integrator has to 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 end product. For the User’s Guide the required FCC statements outlined in the User’s Guide Requirements section must be in a prominent location. USER’S GUIDE REQUIREMENTS “To comply with FCC’s RF radiation exposure requirements, the antenna(s) used for this transmitter must be installed such that a minimum separation distance of 20cm is maintained between the radiator (antenna) ...
