RF EXPOSURE EVALUATION 1.PRODUCTINFORMATION Product Description mPCIe LoRa Concentrator Board Model Name NM0824-I FCC ID 2AO93–NM0824-I 2.EVALUATION METHODANDLIMIT Human exposure to RF emissions from mobile devices(47CFR§2.1091) may be evaluated based on the MPE limits adopted by the FCC for electric and magnetic field strength and/or power density, as appropriate, since exposures are assumed to occur at distances of 20 cm or more from persons. The device under test (mPCIeLoRa Concentrator Board) is neither a mobile device nor a RF exposure product and it is not closed to 20cm distance from persons LIMITS FOR GENERAL POPULATIONIUNCONTROLLED EXPOSURE Frequency Range (MHz) E-field Strength (E) (V/m) Magnetic Field Strength (H) (A/m) Power Density(S) (mW/cm 2 ) Averaging Time IEl 2 IHl 2 or , S(Minutes) 0.3--1.34 614 1.63 (100)* 30 1.34--30 824/f 2.19/f (180/f 2 )* 30 30--300 27.5 0.073 0.2 30 300--1500 -- -- f/1500 30 1500--100,000 -- -- 1.0 30 *Note: 1.f= Frequency in MHz*Plane-wave Equivalent Power Density 2.The averaging time for General Population/Uncontrolled exposure to fixed transmitters is not applicable for mobile and portable transmitters.

Datasheet ANT-915-IPW1-RPS 915 MHz LPWA Weatherproof Antenna Applications • Low-power, wide-area (LPWA) applications ―LoRaWAN ® , ITU-T Y.4480 ―WiFi HaLow™ (802.11ah) • Remote control, monitoring and sensing • Internet of Things (IoT) devices • ISM applications Features • Performance at 902 MHz to 930 MHz ―VSWR: ≤ 1.8 ―Peak Gain: 2.7 dBi ―Efficiency: 99% • Hinged design with detents for straight, 45 degree and 90 degree positioning • IP67 rated • RP-SMA plug (female socket) connector The ANT-915-IPW1-RPS antenna is a hinged-whip IP67-rated dipole antenna designed for use in 915 MHz frequency bands for low-power, wide-area (LPWA) applications such as LoRaWAN ® and WiFi HaLow™ as well as ISM and remote control applications. The ANT-915-IPW1-RPS provides a ground plane independent dipole antenna solution. The hinged design allows for the antenna to be positioned for optimum performance and reduces the potential for damage from impact compared to a fixed whip design. The antenna attaches with an RP-SMA plug (female socket) connector. Ordering Information Part NumberDescription ANT-915-IPW1-RPS Hinged whip LPWA antenna with RP-SMA plug (female socket) connector Available from Linx Technologies and select distributors and representatives. 2 DatasheetANT-915-IPW1-RPS IP (Ingress Protection) Rating An ingress protection rating (IP rating) refers to the capability of a device to withstand the ingress of dust and/or water under specified conditions. IP rating is typically reserved for marketable product (device) rather than constituent components because design and assembly may affect performance of the device under testing. IP-rated antennas are designed to support the specified level of ingress protection and may be tested in a standalone configuration, however IP testing should be performed on the complete end product to ensure desired performance.

ANT-915-IPW1-RPS Antenna Dimensions 3 DatasheetANT-915-IPW1-RPS Antenna Orientation The ANT-915-IPW1-RPS antenna is characterized in two antenna orientations as shown in Figure 2. The antenna straight orientation characterizes use of an antenna attached to an enclosure-mounted connector which is connected by cable to a printed circuit board. Although the antenna is a dipole not requiring a ground plane for function, characterization with an adjacent ground plane, (102 mm x 102 mm) provides insight into antenna performance when attached directly to a printed circuit board mounted connector. The two orientations represent the most common end-product use cases. On edge of ground plane, bent 90 degreesStraight, without ground plane Figure 2. ANT-915-IPW1-RPS Antenna on Evaluation PCB LPWA: LoRaWAN ® ITU-T Y.4480, and Sigfox ® LoRaWAN and Sigfox LPWA technologies operate within several of the frequencies supported by the 915-IPW1-RPS antenna.

Figure 3. ANT-915-IPW1-RPS at Edge of Ground Plane, Bent 90 Degrees (Edge Bent) VSWR Figure 4 provides the voltage standing wave ratio (VSWR) across the antenna bandwidth. VSWR describes the power reflected from the antenna back to the radio. A lower VSWR value indicates better antenna performance at a given frequency. Reflected power is also shown on the right-side vertical axis as a gauge of the percentage of transmitter power reflected back from the antenna. 915902930 0 10 20 30 40 1 2 3 4 5 900905910915920925930935 Reflected Power (%) VSWR Frequency (MHz) Figure 4.
