The silent network behind your cold chain.
Moving temperature-sensitive cargo across South Africa, the choice of communication protocol matters as much as the refrigeration. There is no single answer, so Augos blends RF, LoRa, 4G and NB-IoT to fit the journey, and unifies the data in one platform.
- No one protocol fits every leg. RF suits the warehouse, 4G the high-value long haul, LoRa and NB-IoT the remote, multi-year-battery jobs.
- A hybrid deployment, NB-IoT on the pallet plus RF in the DC, cut spoiled cargo at the receiving dock by 40% for one provider.
- Whatever the mix, the platform unifies every device into one auditable record for tracking and compliance.
Optimising for the South African landscape
For temperature-sensitive cargo moving from farm to export terminal across a large country, the communication protocol is as critical as the refrigeration unit. The terrain forces a strategic blend to handle:
- Vast rural areas that need long-range, low-power links.
- Infrastructure gaps that demand protocols able to cope with patchy cellular coverage.
- Cost, balancing real-time tracking against data budgets.
One logistics provider runs a hybrid Augos system: NB-IoT for pallet-level, long-haul monitoring, with multi-year battery life across the Karoo, plus RF sensors inside their distribution centres. That mix cut spoiled cargo at the receiving dock by 40% and gave the auditable data needed for insurance claims when a transit break occurred.
Matching the protocol to the leg
The right choice depends on what the cargo's journey demands:
- RF, for the warehouse and DC. High bandwidth and low latency over short range, for fast, precise, real-time updates where power is not a concern.
- 4G, for high-value long distance. Broad cellular coverage and high bandwidth for critical real-time tracking, at the cost of higher power, usually mains or vehicle power.
- LoRa, for vast rural routes. Long range on very low power, with months of battery life, for slow, small data over distance.
- NB-IoT, for individual pallets. The lowest power of all, with good cellular penetration and years of battery life on tiny data bursts.
The platform that ties it together
Whichever protocols you use, the Augos platform is the hub that turns scattered sensor data into one picture:
- One place. RF, 4G, LoRa and NB-IoT all flow into a single location, ending fragmented, siloed reporting.
- Real-time visibility. Track temperature and location live, and intervene before a deviation becomes spoilage.
- Advanced analytics. A detailed audit map of the whole journey, ready for compliance and predictive maintenance.
Which protocol is best for long battery life?
NB-IoT. Its ultra-low power draw and small data bursts give multi-year battery life, which makes it ideal for individual pallet and package monitoring on long journeys.
Why is RF best inside a warehouse?
RF offers high bandwidth and low latency over short range, so it gives fast, high-precision, real-time updates within a distribution centre where power and coverage are not a constraint.
Do I have to choose just one?
No, and you usually shouldn't. Most operations blend protocols, for example NB-IoT on the pallet for the long haul and RF inside the DC. The Augos platform brings all of them into one place, so the mix is invisible to the people using the data.
