The main purpose of Internet of Things (IoT) is to embed connectivity into everyday devices, making them smarter and adding more value. Due to constraints such as cost, bandwidth, power consumption, and communication range, not all IoT devices have direct connection to the Internet. This requires a gateway to deal with the communication protocol used by each device and connect it with the Internet towards providing external access for users. In this paper, we introduce an open-source multi-radio gateway to consumer electronics applications.
