Anritsu NB-IoT Uplink and Downlink Measurements

Click2Contact

Anritsu has announced the availability of the NB-IoT Uplink Tx Measurement software and NB-IoT Downlink Waveforms package supporting 3GPP RF measurement tests for NB-IoT devices. Installing the NB-IoT options in the MT8870A Universal Wireless Test Set enables evaluation of communications equipment with built-in NB-IoT functions as well as tests of the RF TRx characteristics of modules. Additionally, a fully automatic measurement application is provided for controlling measuring instruments and chipsets at prototyping and mass-production testing. These application software packages can be used to simplify test program creation and automate measurement, cutting users’ test software development man-hours by about 90%.

Narrowband IoT (NB-IoT) is the latest standard of wireless technology that has been developed to support IoT devices and services. NB-IoT offers several advantages, including improved power consumption, extended in-building coverage, improved security and privacy features. But to be able to meet to growing demand for NB-IoT modules, chipset vendors are looking at cutting the cost of manufacturing by improving measurement efficiency. Anritsu has worked closely with chipset vendors to develop a turnkey system supporting fully automatic measurement. These latest options make full use of optimisation technology developed as a manufacturing solution for 2G/3G/4G terminals and have been developed as a multidevice test solution for cutting measurement costs per device as far as possible.

The MT8870A is a universal wireless test set designed for the mass production of wireless communication devices, including 2G/3G/LTE/LTE-A, W-LAN, Bluetooth, GPS and FM technologies. Up to four high-performance test units can be installed in one main chassis, with each unit performing completely independent parallel measurements to evaluate up to four wireless communications devices simultaneously.

Installing the developed NB-IoT measurement software in the MT8870A supports fast and easy 3GPP NB-IoT RF tests, including power, frequency, modulation accuracy and Rx sensitivity.
