2AF6B-RAK3272WisDuo LPWAN SiP

Documentation Center Description The RAK3272-SiP Breakout Board was designed to allow easy access to the RAK3172-SiP pins to simplify development and testing. The microcontroller GPIO pins are accessible via 2.54 mm headers. The breakout board itself has a RAK3172-SiP (based on STM32WLE5) as its core. The STM32WLE5 is part of STM32WLE5x family. This core is based on an Arm® Cortex®-M4 core running at 48 MHz, and a sub-GHz radio based on Semtech SX126x. The board complies with Class A, B, & C of LoRaWAN 1.0.3 specifications and also features LoRa Point-to-Point (P2P) communication mode, which helps you in implementing your own customized long-range LoRa network quickly. It is also RUI3 compatible which allows you to create custom firmware using RUI3 APIs.

In accordance with 47 CFR FCC Part 2 Subpart J, section 2.1091 this device has been defined as a mobile device whereby a distance of 20cm normally can be maintained between the user and the device. MPE Calculation Method according to OET Bulletin 65 Power Density: S (mW/cm 2 ) = PG/4πR 2 or EIRP/4πR 2 Where: S = power density (mW/cm 2 ) P = power input to the antenna (mW) G = power gain of the antenna in the direction of interest relative to an isotropic radiator R = distance to the center of radiation of the antenna (cm) The worst-case mode (the configuration having highest EIRP) specified: Lora DTS: 13.21 dBm with 2.3 dBi antenna gain From the RF output power, the minimum mobile separation distance, d=20 cm, as well as the antenna gain, the RF power density can be calculated as below: For Lora DTS: S (mW/cm 2 ) = PG/4πR 2 = 0.007 mW/cm 2 Limits for Maximum Permissible Exposure (MPE) according to FCC Part 1.1310: 1.0 mW/cm2 Prüfbericht - Produkte Test Report - Products Prüfbericht - Nr.: Test Report No. CN22LKDS 001 Seite 29 von 30 Page 29 of 30 IC requirements: The EUT shall comply with the requirement of RSS-102 section 2.5.2. Exemption from Routine Evaluation Limits – RF Exposure Evaluation RF exposure evaluation is required if the separation distance between the user and/or bystander and the device’s radiating element is greater than 20 cm, except when the device operates as follows: at or above 300 MHz and below 6 GHz and the source-based, time-averaged maximum e.i.r.p. of the device is equal to or less than 1.31 x 10 -2 ƒ 0.6834 W (adjusted for tune-up tolerance), where ƒ is in MHz; RF exposure evaluation exempted power for Lora FHSS & DTS: 1.37 W The worst-case mode (the configuration having highest EIRP) specified: Lora DTS: 13.21 dBm Antenna Gain: 2.3 dBi The Max. e.i.r.p. for Lora DTS: 15.51dBm = 0.036 W Both e.i.r.p. for the Lora FHSS and Lora DTS are less than the RF exposure evaluation exempted power. So RF exposure evaluation is not required. “RF Radiation Exposure Statement Caution: This Transmitter must be installed to provide a separation distance of at least 20 cm from all persons.”
