The 3GPP recently completed the standardization of a new LTE-based narrowband technology to support the emerging needs of cellular-IOT devices. Known as Cat-NB1 (formerly NB-IoT), this new low data rate category will enable the development of ultra-low power, ultra-low cost solutions that can leverage the existing LTE infrastructure for a new wave of connected devices. However, in order to efficiently leverage the Cat-NB1 standard, a new approach to cellular SoC design is required, where low data rate transfer in very large time intervals is the goal. As such, solution designers might step out of their “comfort zone” and reevaluate existing modem solutions.
