SX1258
The SX1258 is a highly integrated RF front-end to digital I and Q modulator/demodulator Multi-PHY mode transceiver capable of supporting multiple constant and non-constant envelope modulation schemes.
It is designed to operate over the 779MHz to 787MHz Chinese license-exempt frequency bands. Its highly integrated architecture allows for a minimum of external components whilst maintaining maximum design flexibility. All major RF communication parameters are programmable and most of them can be dynamically set. The SX1258 offers support for both narrow-band and wide-band communication modes without the need to modify external components. The SX1258 is optimized for low power consumption and channelized operation. TrueRF technology enables a low-cost external component count whilst still satisfying SRRC regulations.

The LoRaWAN-based gateway is the physical layer (PHY) interface for the LoRaWAN network server (LNS). On the one hand, it listens to certain parts of the radio spectrum and decodes LoRa®-modulated signals originating from LoRa-based sensors. On the other hand, the gateway transmits messages from the network down to a sensor as LoRa-modulated signals.
LoRaWAN 区域参数中规定了接收和传输这些信号的确切参数。由于世界不同地区有不同的监管要求,因此参数因地区而异。
