The R&S®VSE-K106 option covers the modulation measurements for narrowband IoT (NB-IoT) specified by 3GPP for base stations and user equipment.
NB-IoT focuses specifically on indoor coverage, low cost and long-life battery devices. The NB-IoT technology can be deployed “in-band” in a spectrum allocated to LTE within a normal LTE carrier or standalone for deployments in a dedicated spectrum specifically targeting GSM refarming.
