Rohde & Schwarz and ASTRI jointly demonstrate NB-IoT signal analyser and base station solutions at Mobile World Congress 2018 in Shanghai

Rohde & Schwarz (R&S) and Hong Kong Applied Science and Technology Research Institute (ASTRI) are showcasing the latest NB-IoT standard-compliant base station solutions at the Mobile World Congress 2018 in Shanghai, China. The solutions use R&S FSW26 signal and spectrum analyser from Rohde & Schwarz for 3GPP NB-IoT standard-compliant BS downlink signals. The demonstration revealed ASTRI’s latest NB-IoT Base Station (BS) solution consisting of Sunnada NXP B4850 based Baseband Unit (BBU) and Network Radio Remote Unit (RRU).

The R&S FSW26 together with its EUTRA/LTE NB-IoT Downlink Measurements software (R&S FSW-K106) successfully demodulated the 3GPP NB-IoT compliant signals, i.e. Narrowband Physical Downlink Shared Channel (NPDSCH), Narrowband Physical Downlink Control Channel (NPDCCH), Narrowband Physical Broadcast Control Channel (NPBCH), Narrowband Reference Signal (NRS), Narrowband Primary Synchronization Signal (NPSS) and Narrowband Secondary Synchronisation Signal (NSSS).

ASTRI’s solution enables additional NB-IoT features on the existing NXP B4860 LTE-A BS platform, purely through software upgrade. The system supports both LTE-A and NB-IoT, simultaneously on the same BBU. That makes it possible to deploy new NB-IoT and LTE-A cellular networks in the most effective and cost-efficient manner. Furthermore, the software-based design is highly customisable – supporting special requirements on private networks, such as LTE 230MHz systems on China electrical networks.

The demonstration is taking place at ASTRI’s booth (Hall N1 Stand N1.E60) in MWC 2018 at the Shanghai New International Expo Centre (SNIEC), Shanghai, China from 27 – 29 June 2018.


Hong Kong Applied Science and Technology Research Institute Company Limited (ASTRI) was founded by the Government of the Hong Kong Special Administrative Region in 2000 with the mission of enhancing Hong Kong’s competitiveness in technology-based industries through applied research.  ASTRI’s core R&D competences in various areas are organised under seven Technology Divisions, namely Communications Technologies, Electronics Components, Mixed Signal Systems IC, Advanced Digital Systems, Opto-electronics, Security and Data Sciences, and Intelligent Software and Systems. Five areas of applications including financial technologies, intelligent manufacturing, next generation network, health technologies, and smart city are identified for major pursuit.
