INTRODUCTION This document presents the result of RADIO test carried out on the following equipment: LoRa IoT Station 915MHz in accordance with normative reference. The device under test integrates:  a multifrequencies wireless transceiver LoRa.  A GPS module already certified FCC and IC.  A 2G / 3G module (HUAWEII MU509c) already certified FCC and IC (FCCID: QISMU509C and IC Number: 6369A-MU509C). The applicant declares that the distance between the whip antenna for LoRa mode and integral antenna for GSM mode will be superior to 20cm. So collocation tests are limited: only measurement of the conducted disturbances are necessary and performed. The host device of certified modules shall be properly labeled to identify the module within. 2. PRODUCT DESCRIPTION Class: A Utilization: Tele transmission Antenna type and gain: External antenna 6dBi Operating frequency range: from 923.3MHz to 927.5MHz Number of channels: 8 Channel spacing: 600 kHz Modulation: LoRa Power source: 48Vdc via POE or solar panel (range 11Vdc to 30Vdc) The modulation plan in transmission (Downlink) is the following: SF BW (KHz) Débit (kbps) 7 500 21875 8 500 12500 9 500 7031 10 500 3906 11 500 2148 12 500 1172 The rates evaluated at the request of the applicant are: SF7 and SF12. Power level, frequency range and channels characteristics are not user adjustable. The details pictures of the product and the circuit boards are joined with this file.
