Module Specification ITEM SPECIFICATION Protocol EPC global UHF Class1 Gen2 / ISO 18000-63 Modulation DSB-ASK , PR-ASK Frequency ETSI : 865.6MHz~867.6MHZ FCC : 902.75MHz~927.25MHz RF Output Port 4 Port( Default ANT1 ) Max Tx Power =< 30dBm (-0.5dB) Power Control 5dBm to 30dBm (1dB step) Operating Temperature -10 ̊C to +50 ̊C Communication UART ( Default Baud rate:115200bps ) Power Supply Typical 5.0V / 2.0A 5 | 12 RFID at your service 2. Hardware Interface 2.1 Antenna Connections Air12 has 4 RF Ports ( ANT1, ANT2,ANT3,ANT4) thru MMCX Connector. The maximum RF Power that can be supplied to 50 ohm load at each port is 30dBm. RF port can be used one at a time, default value is ANT#0. Please refer to Command document for selecting the antenna port. 2.2 Antenna Requirements Air12 is affected by the characteristics of the antenna. When the impedance is 50 ohm and the reflection loss is -20 dB or less in the frequency band of the applied antenna, it has good characteristics. When RF power is output while the antenna port is open, the RF module may be damaged. 2.3 Digital/ Power Interfaces There a re power, Serial communication signal and power on/ off signal in Digital connector. These signals are provided by Yeonho 05002HR-H16J05 and 05002HR-H30J05 on the top of the module.

Environmental Specification Air12 can be connected to the Host in two ways. The 16-pin zip connector can be used by connecting to the host using the UART interface. And if you use a 30-pin zip connector, you can implement the desired terminal with only Air12. It is recommended that fixing the module to the main board in any of connection ways. Air12 generates a lot of heat when it is operating a Max power (30dBm), it can alleviate temperature rise during operation of the module by diffusing the heat of the module to the main board. In addition, when the module is mounted on the main board, the PSR is opened in the module area so that the main board and the ground of the module can sufficiently contact each other. Shield is recommended because harmonics generated by the Host Processor may be emitted and introduced into the antenna of Air12, which may cause performance degradation. 9 | 12 RFID at your service 4.

MPE Calculation / RF Exposure Product: RFID Reader Module Applicant: Apulse Co.,Ltd Model: Air12 Address: 3-508,509, 120, Gunpocheomdansaneop 2-ro, Gunpo-si, Gyeonggi-do, 15880, Republic of Korea FCC ID: 2BR2ZAIR12 The FCC requires that the calculated MPE be equal to or less than a given limit dependent on frequency at a distance of 20 cm from the device to the body of the user. According to §2.1091, §2.1093 and §1.1307(b), systems operating under the provisions of this section shall be operated in a manner that ensures that the public is not exposed to radio frequency energy level in excess of the Commission’s guidelines. Classfication The antenna of this product is at least 20 cm away from the body of the user. So this product is classified as mobile device. S = EIRP/4 π R 2 Where S = Power density EIRP = Effective Isotropically Radiated Power R = distance to the centre of radiation of the antenna Values S = 1.0 mW/cm 2 for General population uncontrolled exposure (FCC Part 1.1310 Radiofrequency radiation exposure limits) S = 1.0 mW/cm 2 PT(RFID) = 29.04 dBm (801.68 mW) : measured maximum output power G = Antenna gain = 5.3 dBi (3.388 in linear terms) EIRP = PT x G R = 20 cm Calculation EIRP(RFID) = 801.68 x 3.388 = 2 716.44 mW S(RFID) = 2 716.44/12.56 x (20) 2 = 2 716.44/5024 S(RFID) = 0.540 42 mW/cm 2 Conclusion This confirms compliance to the required radio frequency radiation exposure limit of 1.0 mW/cm 2 at 20 cm operation.
