NB-IoT options reduce test software development by almost 90 per cent
Anritsu announces the availability of the Narrowband-IoT (NB-IoT) uplink Tx measurement MX887067A software and NB-IoT downlink waveforms MV887067A package supporting 3GPP RF measurement tests for NB-IoT devices. It also strengthens the functions of the popular Universal Wireless Test Set MT8870A.
Installing the NB-IoT options in the MT8870A enables the evaluation of communications equipment with built-in NB-IoT functions as well as tests of the RF TRx characteristics of modules. These same options are bundled with a PC application supporting signal analysis to assist customers with development work and design testing. 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 customers’ test software development man-hours by about 90 per cent, claims Anritsu.
Narrowband-IoT is the latest standard of wireless technology that has been developed to support IoT devices and services. NB-IoT offers advantages, including improved power consumption, extended in-building coverage, lower cost and improved security and privacy features. 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 multi-device test solution for cutting measurement costs per device.
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 a 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 (NB-IoT Uplink Tx Measurement MX887067A and NB-IoT Downlink Waveforms MV887067A）in the MT8870A supports 3GPP NB-IoT RF tests, including power, frequency, modulation accuracy and Rx sensitivity.
