13 Quick Facts about GTEL GTEL focuses on Wireless Technologies and seeks to form skilled engineers for the brazilian telecom sector. GTEL was created in year 2000 just before the first contract with Ericsson Research was signed GTEL holds a PRONEX: an Excellence Grant from the Brazilian National Research Agency (CNPq). The Group has developed research projects in partnership with other academic labs, industry and research institutes The GTEL/ERiCSSON cooperation has been the largest and most important industrial partnership at GTEL. GTEL is a member of the Wireless World Research Forum (WWRF) 13

20 GTEL Management Principles 20

21 Management Principles Project and Program Management Research strategy basic research w/technological focus/use-inspired Human Resources training including both scientific and technology -oriented focuses Matrix-like organization Group-collaborative work Workflow based on clear processes, roles and resposibilities Appropriate workflow supporting tools Software Engineering as support 21

22 Project and Program Management GTEL runs a program of projects in partnership with different partners Professional Project Management Adoption of selected PMI/PMBok practices Use of project plans as basis for project control Project management software supporting tools HR sharing among multiple projects Some challenges How to better choose the projects that constitute the portfolio of the program Human resources retention 22

23 General Research Steps Technology Conception Improvements on Physical Layer, Intelligent Signal Processing, Improvements on higher layers, Radio Resource Management Link-Level Evaluation Standard-like precise simulation for evaluation of proposed technologies Impact at System-Level Wireless network simulation with sophisticated propagation, mobility and traffic models Implementation of protocols and signaling as specified by standards Evaluation of impact of new technologies at the application level Generation of critical information about planning and dimensioning of modern wireless networks 23

26 Human Resources Training GTEL has a standard program for training personnel in wireless communications It is called Scientific and Technological Initiation Program in Wireless Communications Undergraduate students are recruited from Electrical Eng., Teleinformatics Eng. and Computer Science courses The program is composed of: Basic Overview Program (6 mos) Specialization 1 Physical Layer and Signal Processing (1 yr) Specialization 2 Access Networks (1 yr) Program on Simulation Techniques (6 mos) Program on Advanced Programming Techniques (6 mos) This training is conducted mostly as a self-study program but with coaching and mentoring from older GTEL members and periodical evaluation of the results achieved. 26

27 Workflow Tools Meetings (a lot of!) Shared ToDo Lists Wiki (bank of ideas, concurrent editing of reports) BLOG (meeting notes) Knowledge Management Tool (KM) Time Allocation Spreadsheet 3GPP Mirror Site and search engine Intranet Web-mail On-line library system SEPIN automated activity reporting system GTEL member list directory with contact information Video surveillance system Protected area w/ technical reports from on-going/previous projects 27

28 GTEL Intranet GTEL New Web Site 28

29 Software Engineering Strategy Object Oriented methodology UML software project Adoption of some CMM practices 29

30 GTEL Technical Organization 30

31 GTEL Technical Organization - Basics GTEL is organized into 5 technical groups (TG s) [see next slide] Each TG is composed typically of a leader plus 3-4 researchers GTEL is organized as a matrix where project teams are composed by personnel from different TG s TG s are responsible for keeping the technical excellence of its members 31

32 Technical Groups (TGs) GTEL Coordination & Project Management CORE GROUPS SUPPORT GROUPS Technical Groups TG s Physical-Layer and Signal Processing (PHY) Radio Resource Management (RRM) UMTS System Level (USL) Internet Multimedia Services (IMS) Link-Layer (LL) PROJECTS 32

33 PHY TG - Example of Skills Space-time processing (equalization, beamforming, MIMO, ST coding) Bit/Waveform-level adaptive processing and filtering Adaptive/Optimized Transceiver Architectures (e.g. link adaptation) Microscopic (space/time/frequency) channel modelling Channel estimation Blind signal processing and source separation Computational intelligent methods (e.g. neural networks) Phy-layer level performance evaluation (issues such as synchronization, equalization, channel estimation and link adaptation) Emerging topics: information geometry 33

34 RRM TG - Example of Skills Dynamic Radio Resource Allocation/Management (RRM) and Common/Joint RRM (CRRM), Multi-access networks RRM Problems in general Mathematical modelling and algorithm conception Interference management Power Control, CAC, Load control, packet scheduling, channel allocation, etc. Mathematical/Algorithmic Tools Advanced analysis methods for radio resource management Linear and Non-Linear Optimization Heuristic Algorithms (NP hard problems, Genetic Algorithms, etc) Game theory, Utility Theory System-level modelling and performance evaluation of RRM techniques 34

35 USL TG - Example of skills 3GPP UMTS RAN : acquainted to 3GPP standards IEEE WLANs (802.11x) Radio Network Algorithms and Radio Resource Management Evolved UMTS Terrestrial RAN modes (HSDPA and Enhanced Uplink) Development of standards-based large-scale system-level simulators Packet-level and Flow-level processing and performance evaluation QoS of Emerging Services in UMTS networks 35

38 Industrial Cooperation 38

39 National Context of the Partnership The partnership is inserted in the brazilian IT incentives law The main objective of the law is to help fill in the gap between Brazil and more developed countries in the fields of informatics, microelectronics, telecommunications, among others Cooperative research between industry and universities is a well-known effective tool to boost technological advancement, as experimented successfully in other countries 39

41 National Context (Cont.) In Brazil there is a need to strengthen the link between growing scientific knowledge and technological advancement Brazilian engineers and scientists need a more product-oriented view of their R&D work The IT incentives law facilitates the interaction between universities and IT industries in face of the need of technological advancement and lack of appropriately trained professionals 41
