Introduction The BEL-LWCC-915 LoRaWAN Concentrator miniPCIe-SPI card is a gateway front end module based on Semtech SX1302 Corecell Design in Mini PCIe Form Factor. It enables system integrators to build high-performance, certified LoRaWAN gateway solutions. The module acts as an air interface at 915MHz band for data collection from sensors. The BEL- LWCC-915 in conjunction with a computing element can transmit and receive data with LoRa standard and perform remote data collection. The LoRa modem in the module can give wireless remote access with low time-on-air links with longer battery life of the system. The LoRa module needs very less power in transmit mode owing to the higher sensitivity of the receive modems. It can also sense multiple spreading factors simultaneously thereby reducing collisions on the air and better response times. a.

Bharat Electronics Ltd Theory of Operation/Technical Description – FCC ID: 2A9HG-BELLWCC915 The CSS modulated signal based on LoRA air standard is generated at SX1302 chip which is transferred through a proprietary interface to SX1250 chip which is a transceiver for LoRA US915 band. One out of two SX1250 on board will upconvert and amplify the signal upto a maximum of +22dBm. This signal is furtheramplified by another front end chip SKY66420. SKY66420 has got a Transmit receive switch along with amplifier for transmit path and LNA for receive path. The received signal is again received and downconverted to baseband by another SX1250 chip on board. SX1261 does the frequency scanning job. The data to be transmitted or data received is handledby SX1302 and the exchange happens through mPCI interface. - RF signal flow: RF is generated from SX1250 with the I-Q data obtained from SX1302. It passes through the matching network and filters to SKY66420. From SKY66420 it passes through matching network to a u-FL connector where antenna is coupled. From the same antenna signal is received through the u-FL connector to SKY66420 which is low noise amplified and fed to SX1250 and SX1261. The demodulated I- Q data is transferred to SX1302. - Description of Antenna system (Baluns, Multiplexers) The antenna can be directly coupled to the Concentrator miniPCIe-SPI board with a u-FL to SMA cable or there can be u-FL to u-FL adapter cable to carrier-card where the LoRaWAN Concentrator miniPCIe-SPI board is mounted. On the carrier-card the antenna can be directly connected to the SMA edge mount connector which is in-turn mounted to the u-FL connector. The antenna has to be an omnidirectional type with 3dBi+/-0.5dB gain so as to use with the FCC ID mentioned on the module.

The gain of the antennas used in the product is extracted from the Antenna data sheets provided and also the maximum total power input to the antenna is measured. Through the Friis transmission formula and the maximum gain of the antenna, we can calculate the distance, away from the product, where the limit of MPE is reached. Although the Friis Transmission formula is far field assumption, the calculated result of that is an over-prediction for near field power density. It is taken as worst case to specify the safety range. 1.2 RF Exposure Limit According to FCC 1.1310: The criteria listed in the following table shall be used to evaluate the environmental impact of the human exposure to radio-frequency (RF) radiation as specified in 1.1307 (b) showed in Table 1. Table 1: Limits for Maximum Permissible Exposure (MPE) as per FCC Frequency Range (MHz) Electric Field Strength (V/m) Magnetic Field Strength (A/m) Power Density (mW/cm²) Limits for Occupational / controlled Exposures 300 - 1500 -- -- F/300 1500 – 100000 -- -- 5.0 Limits for General population / Uncontrolled Exposure 300 - 1500 -- -- F/1500 1500 – 100000 -- -- 1.0 F or ƒ = Frequency in MHz 1.2.1 Friss Formula Friss Transmission Formula: Pd = (Pout * G) / (4*pi*r²) Where Pd = power density in mW/cm² Pout = output power to antenna in mW G = gain of antenna in linear scale Pi = 3.1416 R = Distance between observation point and the center of radiator in cm If we know the maximum gain of the antenna and the total output power to the antenna, through calculation, we will know MPE value at distance 20cm.

MPE evaluation is performed for 20 cm saperation distance 2. MPE evaluation is performed for highest antenna gain of 3.0 dBi 1.5 Conclusion: The Power density of the EUT is less than defined limit as shown above, hence EUT is exempted from routine SAR evaluation, this evaluation is only applicable to RFID transmission
