LoRaWAN Concentrator 868MHz

The concentrator module iC880A is targeted for a huge variety of applications like Smart Metering, IoT and M2M applications. It is a multi-channel high performance transmitter/receiver module designed to receive several LoRa packets simultaneously using different spreading factors on multiple channels. The concentrator module iC880A can be integrated into a gateway as a complete RF front end of this gateway. It provides the possibility to enable robust communication between a LoRa gateway and a huge amount of LoRa end-nodes spread over a wide range of distance. The iC880A needs a host system for proper operation. This host system can be a PC or MCU that will be connected to
iC880A via USB or SPI.

iC880A is able to receive up to 8 LoRa packets simultaneously sent with different spreading factors on different channels. This unique capability allows to implement innovative network architectures advantageous over other short range systems:
+ End-point nodes (e.g. sensor nodes) can change frequency with each transmission in a random pattern. This provides vast improvement of the system robustness in terms of interferer immunity and radio channel diversity.
+ End-point nodes can dynamically perform link rate adaptation based (by adapting their spreading factors) on their link margin without adding complexity to the protocol. There is no need to maintain a table of which end point uses which data
rate, because all data is demodulated in parallel.
+ The capacity of the air interface can be increased due to orthogonal spreading
factors.
+ Due to the high range a star topology can be used. This results in simple implementation avoiding complex network layers, wireless routers and additional network protocol traffic.
