David López Pérez

Expert at Huawei Technologies France

Since August 2020, I am an Expert and a Team Leader at Huawei Technologies France. 

Prior to this, I earned my PhD degree in Wireless Communications at the University of Bedfordshire (UoB), Luton, UK in Apr. 2011, and received my Bachelor and Master degrees in Telecommunications from the Miguel Hernandez University (UMH), Elche, Spain in Sep. 2003 and Sep. 2006, respectively.

From May 2012 to Feb. 2020, I was with Nokia Bell Labs (former Alcatel-Lucent), Dublin, Ireland, where I was a Distinguished Member of Techical Staff and a Senior Research Scientist, and worked at different positions, all of them related to small cells and future indoor networks research.

  • In 2015, I visited ---on rotation--- the Murray Hill and the Crawford Hill locations for 9 months and worked on Wi-Fi Boost.

From Aug. 2011 until Jan. 2012, I was a Research Associate at King's College London (KCL), London, UK, where I investigated inter-cell interference coordination schemes for heterogeneous networks.

  • In 2011, I was an invited researcher at DOCOMO Innovation Labs in Palo Alto, California and worked on mobility management. 
From May 2007 to Dec. 2010, I was a Marie-Curie PhD Fellow at University of Bedfordshire (UoB), Luton, UK, where I participated in both the FP6 Marie Curie research project "RANPLAN-HEC ” (MESTCT-2005-020958), and the first EPSRC-funded research project on femtocells “The feasibility study of WiMAX based femtocells for indoor coverage” (EP/F067364/1), and investigated self-organising and femtocell networks.

In 2006, I took up a research scholarship at Cork Institute of Technology (CIT), Cork, Ireland, where I worked for a year on a project called “UbiOne – The Multi-Modal WiFi Positioning System”. The main goal of the project was to prove that the major disadvantages of the poor accuracy of existing indoor location systems can be overcome by fusing two complementary location techniques, radio signal strength indication (RSSI) and radio signal time of flight (TOF) with a unique self-calibrating approach.

In 2005, I was with VODAFONE SPAIN, working at the Radio Frequency Department in the area of network planning and optimization, where I participated in the development of the VODAFONE Automatic Frequency Planning tool for GSM and DCS networks.
