Introduction to RF Networks
Any number of nodes transmitting and receiving data from one central hub. Sensor nodes can sleep to conserve battery power. No direct communication between the sensor nodes.
Multiple Star Networks
Start networks can be combined by creating multiple star networks on their own PanId’s. Messages can be directed to specific gateways by assigning PanId’s to each sensor.
Multiple gateways can be configured on the same PanId to create a redundant network. All radio traffic travels to all gateways so if you lose a gateway then you have a hot backup. Additional gateways can also be installed in areas of poor reception to improve network coverage. Message de-duplication logic must be built either within the gateway or further down in back end systems connected to the network.
Two or more MCU’s can communicate directly with each other as shown below.
