Challenges for effective and realistic 5G OTA testing

May 1 @ 6:00 pm - 8:00 pm

Abstract-. The path towards an efficient and cost-effective 5G OTA testing scenario is yet to be visible. With a tremendous pressure on 5G standards development, network deployments and device manufacturing, the realistic answers that a 5G OTA test system should provide are far from being obtained. This paper identifies current progress and challenges to achieve an effective and realistic 5G OTA testing.

Dipl.-Ing. in Telecommunications Engineering from Universidad Politécnica de Valencia, Spain, in 1993, Ph.D from King’s College, University of London, UK, in 1996, Innovation Ignite SC from CFEL, University of Cambridge, UK. Research Fellow at King’s College, University of London from 1993 to 1996, he returned to Spain under the first Ramón y Cajal-Reincorporación de Doctores Spanish National Programme in 1996, to Universidad Politécnica de Valencia, as a visiting lecturer. In early 1999 he received the Readership from Universidad Politécnica de Cartagena, Spain, and was appointed ViceDean of the School for Telecommunications Engineering and later that year ViceChancellor for Innovation & Technology Transfer and Head of Department. He holds the Antennas & Propagation Chair at Universidad Politécnica de Cartagena since 2009, and was granted a special permission to foster university-industry cooperation in the field of telecommunications. He is a Chartered Engineer (CEng) by the British Association of Electronic Engineers (IET), IET Fellow, IEEE Senior Member, CENELEC TC106X member, and is the recipient of the R&D J. Langham Thompson Premium, awarded by the British Association of Electronic Engineers (IET), the Spanish National ENISA-La Caixa Emprendedor XXI Award, i-patentes award by the Autonomous Region or Murcia in Spain as well as other national and international awards. Recently, Prof. Sanchez-Hernandez was awarded with Spanish National CincoDías Innovation Award to University-Industry co-operation and named 2015 Murcian Personality for technology. He leads the Microwave, Radiocommunications and Electromagnetism Research Group (GIMRE) at Universidad Politécnica de Cartagena. He has published 5 international books, 3 of them with Artech House USA, over 75 scientific papers in international SCI journals, over 250 conference contributions and over 125 contributions to standardization committees. He is a reviewer of twenty different SCI international journals, conferences and R&D Funding Programmes including those of Spain, Romania and the European Framework Programmes. He is also contributing to wireless communications standards to 3GPP and CTIA international standardization committees, being acknowledged at the latest CTIA Large Form factor devices Test Plan. He is a US councilor for green card grating to scientific talented petitioners. He holds eight patents, extended to the EU, USA, Japan and South Korea, all of them in exploitation. He founded EMITE Ingeniería S.L. in 2006, and since 2009 he is also its CEO. EMITE is a high-tech company which spin-out from Universidad Politécnica de Cartagena, awarded with Vodafone Foundation, ANCES and Spanish National entrepreneurship (Emprendedor XXI) awards, currently being one out of the only four companies worldwide in the advanced telecommunications OTA-chamber wireless characterization of devices market segment. The company is headquartered at the Fuente Alamo High Tech Park in the Region of Murcia (Spain). EMITE designs, develops, manufacturers and commercializes reverberation, anechoic and hybrid chambers for the OTA performance and compliance testing of devices and antennas respect to diverse wireless and cellular 3G, 4G and 5G standards and pre-standards worldwide. The company has offices in the Spain, USA, Canada, Brazil, Israel, Germany, France, Italy, The Netherlands, Belgium, The UK, Ireland, Denmark, Norway, Sweden, Czech Republic, Slovakia, Hungary, Austria, Switzerland, South Korea, Vietnam, India, China, Taiwan R.O.C., Singapore, Australia, New Zealand and Japan, and was selected by the prestigious international standardization committees 3GPP and CTIA as the cutting-edge high tech company for participating on the round robin testing campaigns of wireless devices using RC test systems before they come into the market. In 2014, the US carrier AT&T and the Japanese carrier NTT DoCoMo selected EMITE Test Systems for their advanced LTE and WiFi test plans. In 2016, Australia leading carrier Telstra selected EMITE test equipment for the deployment of their worldwide leading LTE-A wireless network with up to 4 DL CC and 4×4 MIMO, providing wireless throughputs in excess of 1 Gbps. In 2018, Vodafone selected EMITE 5G OTA Test Systems for network and device characterization. With partner’ agreements to large-size multinational companies and test equipment vendors like Keysight Technologies, Rohde & Schwarz, Speag, Anritsu Corporation, National Instruments, Asysol and Comtest, among others, in 2015 EMITE was the first company worldwide to announce the life successful testing of 600 Mbps throughput performance for 4.5G mobile devices over the air using its test systems and an aggregation of 4 carriers over an LTE Advanced device. 2017 EMITE was the first company worldwide to announce OTA testing of 802.11ac devices in signalling mode, in cooperation with Anritsu, and in early 2018 EMITE, together with Vodafone and Ericcson, announced the first worldwide 5G OTA Standalone end-to-end call and lab test. EMITE’s customers include worldwide-leading antenna manufacturers, test labs, carriers, OEMs and research centers throughput the globe, currently recognizing EMITE technology as best available worldwide for RC MIMO OTA testing. In 2019 EMITE announced the worldwide-first over 1Gbps PHY OTA Throughput for a handheld device being measured for WiFi6 (802.11ax). David A. Sánchez Hernández also helps improving public life by coordinating the University and R&D Work Group at the political party Ciudadanos in the Region of Murcia, in Spain.
