Why NB-IoT
Spectrum efficient – 200kHz deployment in licensed spectrum.
Cost-effective – Modest upgrade to carrier’s existing network, and designed low cost from the ground-up.
High reliability – Carrier-grade quality of service (QoS) and security.
Global – Built on 3GPP open standard, ensuring interoperability and scalability.
