iC880A – LoRaWAN\u00ae Concentrator 868MHz<\/span><\/h4>\n<\/li>\n<\/ul>\n
![](\"https:\/\/wireless-solutions.de\/wp-content\/uploads\/2020\/12\/iC880A_SPI_freigestellt-2048x1308.jpg\")
iC880A is able to receive packets of different end devices send with different spreading factors on up to 8 channels in parallel<\/strong>. Due to the fact that the combination of spreading factors and signal bandwidths results in different data rates the use of \u201cDynamic Data-Rate Adaption\u00ae becomes possible. That means that LoRa\u00ae nodes with high distances from the concentrator must use higher spreading factors and therefore have a lower data rate. LoRa\u00ae 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 and the HAL software from\u00a0https:\/\/github.com\/Lora-net<\/a> a complete LoRaWAN\u00ae gateway can be setup easily<\/p>\n\n
