The Narrow Band Internet of Things (NB-IoT) RF performance test solution has been selected by RDA Microelectronics to help accelerate its NB-IoT chipset testing. NB-IoT is a narrowband cellular radio technology designed for the IoT by 3GPP. The deep coverage and extremely low power consumption of NB-IoT have created new R&D challenges in RF performance and new working modes. Chipset makers must evaluate the RF performance under real working modes to ensure a good connection and coverage. By setting the chipset into different working modes with the NB-IoT test solution, RDA can efficiently and completely test the RF performance and, as a result, accelerate chipset development.
