It is based on the newest SX1302 LoRaWAN Gateway chip which allows it to use spreading factors from SF5 to SF12. This greatly improves the throughput and decreases the data collisions in dense networks with many sensor nodes compared with previous generation of gateways based on older SX1301. Improvement on performance comes together with significant reduction of power consumption which reduces the cost of operation and increases long time reliability of the devices. This guide covers the MX1901 and MX1902 version of MatchX M2 Pro Gateway, with the MatchX LPWAN controller version 1.0 or above. The main differences between them are listed in the Table 1.1: ItemMX1902MX1901 Band902-928MHz863-873MHz Maximum Conducted Power+27dBm+27dBm LBTYesYes No. of Channels1616 SF5-105-12 CertificationIEC 60950 -1EN 300200 FCC PART 15.247EN 301489 IP RatingIP66IP66 Table 1.1: Comparison of MX1901 and MX1902 6Chapter 1.

RF Exposure Evaluation For FCC ID: 2AMPF-MX1902 Refer user manual this device is a MX1902, and this device was designed used in Mobile devices that the minimum distance between human’s body is 25cm. Based on the 47CFR 2.1091, this device belongs to Mobile device. The definition of the category as following: Mobile Derives: CFR Title 47 §2.1091(b) (b) For purposes of this section, a mobile device is defined as a transmitting device designed to be used in other than fixed locations and to generally be used in such a way that a separation distance of at least 20 centimeters is normally maintained between the transmitter’s radiating structure(s) and the body of the user or nearby persons. FCC KDB 447498 D01 General RF Exposure Guidance v06 Limit Devices operating in standalone mobile exposure conditions may contain a single transmitter or multiple transmitters that do not transmit simultaneously. A minimum test separation distance ≥ 20 cm is required between the antenna and radiating structures of the device and nearby persons to apply mobile device exposure limits. The distance must be fully supported by the operating and installation configurations of the transmitter and its antenna(s), according to the source-based time-averaged maximum power requirements of § 2.1091(d)(2). In cases where cable losses or other attenuations are applied to determine compliance, the most conservative operating configurations and exposure conditions must be evaluated. The minimum test separation distance required for a device to comply with mobile exposure conditions must be clearly identified in the installation and operating instructions, for all installation and exposure conditions, to enable users and installers to comply with RF exposure requirements. For mobile devices that have the potential to operate in portable device exposure conditions, similar to the configurations described in § 2.1091(d)(4), a KDB inquiry is required to determine the SAR test requirements for demonstrating compliance. When the categorical exclusion provision of § 2.1091(c) applies, the minimum test separation distance may be estimated, when applicable, by simple calculations according to plane-wave equivalent conditions, to ensure the transmitter and its antenna(s) can operate in manners that meet or exceed the estimated distance. The source-based time-averaged maximum radiated power, according to the maximum antenna gain, must be applied to calculate the field strength and power density required to establish the minimum test separation distance. When the estimated test separation distance becomes overly conservative and does not support compliance, MPE measurement or computational modeling may be used to determine the required minimum separation distance. According to FCC Part 1.1307, systems operating under the provisions of this section shall be operated in a manner the ensures that the public is not exposed to radio frequency energy level in excess of the commission’s guidelines.

The formula of calculated the MPE is CPD1 / LPD1 + CPD2 / LPD2 + ......etc. < 1 CPD = Calculation power density LPD = Limit of power density 3. The worst-case situation is 0.198, which is less than “1”. This confirmed that the device comply with FCC 1.1310 MPE limit. 4. The MX1902 work frequency range used is 902 MHz ~ 928 MHz and 2400 MHz ~ 2483.5 MHz, the result close to the limit by the above formula, so we select 2400 MHz and 902MHz to calculate the exclusion power t…
