Estimate aggregate bandwidth for a fleet of IoT sensors, whose individual traffic is tiny but whose count is large.
Concurrent sessions multiplied by per-session bitrate gives the aggregate demand; the overhead factor covers packet headers and retransmissions. Dividing by 8 converts bits per second into bytes to get the data volume. Sizing a link on average usage guarantees congestion at peak, and monthly data volume is what actually triggers a cap or an overage charge on a IoT fleet.
IoT Device Bandwidth
Bandwidth (Mbps) = IoT devices reporting × Average bitrate per device × (1 + overhead)
