Low-power wide-area networks (LPWANs) are the perfect companion to technologies providing short-range communication. While local applications can query, diagnose, or configure an IoT device, the actual connection to the cloud requires gateways and/or routers which add an additional impact to the development and setup of the infrastructure.

Eliminating the need for gateways, IoT devices with cellular connectivity based on the 3GPP Long Term Evolution (LTE) standard can simplify the design and interface to the backend where data is being processed. Additionally, compared to other more-or-less proprietary LPWAN technologies, cellular connectivity can be employed everywhere in the world where there is a mobile LTE network, thus avoiding the need to build up your own infrastructure.

There are different categories of cellular IoT in LTE depending on the need for data rates, latencies, and cost. Together with its partners, Renesas provides an ever-expanding portfolio of solutions to meet all customer needs.
