In wireless modules, the LBT (Listen Before Talk) function typically refers to a wireless communication protocol or mechanism used to listen to the spectrum before transmitting data to ensure the channel is clear, thereby avoiding interference with signals from other devices.

LoRa1262 and LoRa1268 are ultra-low power wireless rf module designed with Semtech's SX1262 and SX1268X chips. They support both (G)FSK modulation and LoRa modulation. The LoRa modulation significantly extends communication range, making it suitable for various short-range IoT wireless communication applications. They feature small size, low power consumption, long transmission distance, and strong anti-interference capability.

Due to its compact and lightweight nature, portable walkie-talkie modules are widely used in outdoor activities and scenarios that involve frequent movement. Meanwhile, outdoor communication demands certain requirements for communication distance and anti-interference capability. The balance between transmission power and power consumption of walkie-talkie modules tests the design capability of the module's functionalities. Excessive functional requirements may lead to uncontrollable module size

The LoRa1280 is a high-performance wireless module operating in the 2.4GHz frequency band, designed specifically for long-range applications in the Internet of Things (IoT).

The LoRa gateway serves as a device connecting terminal equipment to the LoRaWAN network, responsible for collecting data from multiple LoRa base stations and transmitting it to the cloud. It gathers messages transmitted by LoRa nodes and forwards them to LoRaWAN servers, facilitating communication from devices to the cloud. Gateways typically handle packet forwarding, encryption/decryption, and communication with LoRaWAN servers.
