Interoperability
The secure connectivity ecosystem is enabled by an established infrastructure and global specifications, which help to promote confidence, accelerate innovation and reduce costs.
Yet as the pace of innovation accelerates, so too does the risk of market fragmentation and interoperability issues. For example, the increasing deployment of IoT devices with limited bandwidth, power and user interfaces presents new considerations. As does the growing momentum for 5G networks, drive for more sustainable technologies and increasing deployment of integrated solutions.
Overcoming these challenges requires extensive industry engagement and collaboration to promote an interoperable, reliable and scalable connectivity ecosystem.
