Declaration To Innovation, Science and Economic Development Canada Certification and Engineering Bureau P.O. Box 11490, Station H 3701 Carling Avenue (Building 94) Ottawa, Ontario K2H 8S2 Product Description: Charging Station FCC ID: 2BQXJ-MHCR05RR01 IC: 34326-MHCR05RR01 Model/HVIN: MHCR05RR The product: Charging Station (Model: MHCR05RR) contains a certified WIFI module(Model: ESP32-C5-WROOM-1U, FCC ID: 2AC7Z-ESPC5WROOMU, IC: 21098- ESPC5WROOMU) and a certified LORA module(Model: ESP32-C5-WROOM-1U, FCC ID: 2BM2K-M4, IC: 33426-M4). The original WIFI module contains WIFI2.4G, WIFI5G, BT and Zigbee functions, but Charging Station only uses WIFI2.4G and WIFI5G functions, BT and Zigbee are disabled by software. The WIFI antenna and LORA antenna are changed. Details as follows: The WIFI antenna is changed to external PCB antenna with the max WIFI2.4G gain: 1.63dBi<3.86dBi(in the certified WIFI2.4G module report) and the max WIFI5G gain: 2.94dBi<3.22dBi(in the certified WIFI5G module report). The LORA antenna is changed to external PCB antenna with the max gain: 2.36dBi>1.34dBi(in the certified LORA module report) So the conducted test data is unchanged and the data reference accurately represents this device, also performed the new radiated emission test , DFS and the RF exposure evaluation as per KDB 996369 D02.
