RAK7243 2 Pilot Gateway Pro RAK7243 2.1 Overview The outer dimension of Pilot Gateway Pro is 92 x 68.3 x 53.5 mm as shown below. Figure 2 | Outer Dimensions 2.2 Interfaces 6 Figure 3 | Interfaces RAK7243 User Manual V1.
RAK7243 2.3 System Structure The following figure shows the basic concept for LoRaWAN system. RAK7243 Pilot Gateway Pro is the central hardware solution for all LoRa based radio communication. It receives and transmits radio messages. The processing of radio messages as well as the protocol related tasks is done by embedded host system (Raspberry Pi). Received and processed radio messages are being sent to a LoRaWAN server.
RAK7243 2.5.1 LoRa Concentrator RAK2245 Pi HAT RAK2245 Pi HAT is a LoRa Concentrator board which follows the Pi HAT standard, and can be mounted to Pi board with 40-pin connector. RAK2245 Pi HAT Figure 5 | LoRa Hardware Structure 2.6 Power Requirements 8 The Pilot Gateway Pro can be powered by micro USB with 5V. Parameter Min. Typical Active Mode(TX) 1500mA Active Mode(RX) 1560mA Max. Table 2 | Power Requirements 2.
RAK7243 2.8 LoRa RF Characteristics 2.8.1 Transmitter RF Characteristics The RAK2245 has an excellent transmitter performance. It is highly recommended to use an optimized configuration for the power level configuration, which is part of the HAL. This results in a mean RF output power level and current consumption. Note：The maximum output power setting should not exceed 11.73dBm.
RAK7243 Table 5 | TX RF Characteristics 2.8.2 Receiver RF Characteristics It is highly recommended, to use optimized RSSI calibration values, which is part of the HAL v3.1. For both, Radio 1 and 2, the RSSI-Offset should be set 169.0. The following table gives typically sensitivity level of the RAK2245.
