Cellular Data Plan Pricing Models for Embedded IoT Devices
Cellular IoT pricing models rely on dynamic aggregated data pooling and strict protocol optimization to eliminate carrier session rounding penalties across fleets.
Aggregated Cellular Gateway Backhaul
Meaning
Network architecture designs provide connectivity from a local gateway to a core network using multiple wireless links. An aggregated cellular gateway backhaul combines several modems or sims to increase the total capacity and reliability of the uplink. It functions by splitting traffic across several paths simultaneously.
Traffic Distribution
Load balancing algorithms determine how packets move across the available cellular radios. An aggregated cellular gateway backhaul utilizes either per-packet or per-flow distribution to optimize the use of different carriers. These algorithms monitor signal strength and congestion levels on each modem to assign traffic to the most efficient path.
Interface Latency
Timing differences between the various links can cause packets to arrive out of sequence. Jitter buffers manage these delays within the aggregated cellular gateway backhaul to ensure smooth reconstruction of the data stream.
Throughput Resilience
System availability remains high even when a specific network fails. When one link drops, the aggregated cellular gateway backhaul shifts the load to the remaining active channels without dropping the connection. This redundancy prevents the local network from losing its primary internet access during localized carrier outages or tower maintenance.
Redundant hardware configurations often include modems from different manufacturers to avoid common failure modes in the firmware.
