iC880A is able to receive packets of different end devices send with different spreading factors on up to 8 channels in parallel. Due to the fact that the combination of spreading factors and signal bandwidths results in different data rates the use of “Dynamic Data-Rate Adaption” becomes possible. That means that LoRa™ nodes with high distances from the concentrator must use higher spreading factors and therefore have a lower data rate. LoRa™ nodes which are closer to the concentrator can use lower spreading factors and therefore can increase their data rate. This allows to build easy to handle star or multiple star networks without the need of routers or repeaters. In combination with an embedded Linux board like Raspberry Pi, Beagle Bone, Banana Pi and the HAL software from https://github.com/Lora-net a complete LoRaWAN™ gateway can be setup easily.
Software driver: The LoRa™ MAC specification is currently driven by the LoRa Alliance . Currently all available software, firmware and documentation can be found and downloaded from the open source project LoRa-net. It is highly recommended to fully re-use the latest HAL as provided by Semtech on https://github.com/Lora-net
