[28 February 2017, Hong Kong] Hong Kong Applied Science and Technology Research Institute (ASTRI) showcases its latest developments in distributed MIMO technology based on Sunnada’s distributed antenna small cell platform with the Keysight Infiniium High-Performance Oscilloscope at the Mobile World Congress (MWC) 2017 in Barcelona, Spain.
Driving technological breakthroughs in 4.5G and 5G technologies, ASTRI’s distributed MIMO solutions can significantly improve the coverage, capacity and spectral efficiency of indoor and outdoor telecommunications infrastructure.
The demonstration involves LTE MIMO beamforming using Sunnada’s LTE small-cell with four coherent distributed antenna units. It delivers beamformed live downlink video streams to commercial LTE user equipment. The distributed antenna units can be calibrated by ASTRI’s baseband synchronisation algorithms to maintain timing and phase coherence. The system can support up to 64 distributed antenna units to provide even higher beamforming gain. The synchronisation and beamforming quality of the demonstration system are measured by a DSAX96204Q Infiniium High-Performance Oscilloscope with 89601B VSA Software.
While the demonstration reveals a practical system capable of coherent joint transmission across distributed transmission points, ASTRI’s studies also reveal the feasibility of Over-the-Air (OTA) cross transmission points synchronisation in distributed MIMO. ASTRI’s R&D in massive MIMO technology holds vast potential for advanced 5G networks, particularly for 5G indoor ultra-dense networks(UDNs).
ASTRI has been active in LTE R&D since 2008 and already plays a leading role in market-ready LTE and LTE-Advanced small cell and terminal technologies. A pioneer in 5G technologies, the institute is devoted to developing next generation communication systems. Apart from the MIMO algorithm, ASTRI is actively involved in developing and commercialising different 4.5/5G technologies including UDNs, Machine Type Communications (MTC), Device-to-device (D2D), Vehicle-to-Everything (V2X), and C-RAN systems.
The demonstration took place place at the Sunnada booth (Hall 5, Stand 5G70). MWC 2017 is being held at Fira Gran Via, Barcelona, Spain, from 27 February to 2 March.
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.
