Testing LPWAN IoT technology: An essential step to a connected future
We’re well-aware of the billions of connected devices predicted to be in circulation in the coming years as part of the expanding IoT ecosystem. We’ve heard about – and seen trials of – innovative applications in myriad industries, and we’re continually learning of the new cost efficiencies and socio-economic benefits the IoT will deliver. Dr. Hayk Manukyan, Market Solutions Director, VIAVI Solutions (from the recently acquired Cobham Wireless Validation business), examines how we can sustainably and effectively connect this environment, and what operators must do to prepare their networks.

RAN-to-Core testing
Regardless of which LPWAN technology an operator chooses, all must ensure their networks can support millions of active connections and generate revenue from the IoT. Testing this future scenario and building the required a real-life environment is possible using RAN-to-core validation equipment. Operators are breaking down the traditional vertical telecoms silos, disaggregating the network core and converging RAN and core network functions at the edge of the network.

At MWC 2018 VIAVI demonstrated the impact of NB-IoT smart meters in real-time working mobile network environment. The company was able to emulate smart meter devices to validate the capability and performance of the mobile network when flooded with massive amounts of connections and data.

Testing LPWAN technology against real world uses cases is crucial before commercialisation of the networks. It can help operators ensure their networks will be able to perform to high levels, whilst remaining secure.

As the IoT expands, testing too can be scaled up, without the cost and complexity of having to add additional hardware or physical end-points. Assuring service quality – as well as ensuring that networks are robust enough to handle the IoT – is an essential first step on the route to a connected future.
