Custom radio protocols

Custom radio protocols A common topology for IoT networks is a star network, ie. a single hub or gateway which bridges the physical devices and the rest of the world. The network itself can be of any kind but from the outside it looks like a star network: graph TD D1[Device] --> G[Gateway] D2[Device] --> G D3[Device] --> G D4[Device] --> G D5[Device] --> G G --> S[Span] S --> B[Your backend] A two-tiered networking model can make sense for many reasons – running a custom radio protocol can be very efficient for a low number of devices, the range might not be sufficient for a wide area network and the hardware can be made cheaper by using low-cost components for local communication or you might want some level of local autonomy for availability.
