Why would an engineer only use very short-range radios to allow sensor data to travel from node to node until the data reaches the IoT gateway?
- increased bandwidth
- channel requirements
- power constraints
- high availability
Explanation: IoT devices may have power constraints that may only permit the use of very short-range radios. IoT wireless protocols may use a topology that allows sensor data to travel from node to node until the data reaches the gateway.
