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.
The exact parameters which govern the reception and transmission of these signals is specified in the LoRaWAN Regional Parameters. The parameters are regionally differentiated because there are different regulatory requirements in different regions of the world.
