Other Career
Highlights:
• 1990 - 2000 Member of the Canadian committee of CCIR/ study group 8 which studies the international regulations and standards of future personal wireless communications.
• 1999 - 2000 Project leader in Ontario’s Center of Excellence CITO. Lead and participated in projects on CDMA and wireless Internet.
• 1989 - 1998 Project leader in the Telecommunications Research Institute of Ontario (TRIO). Lead several projects on adaptive interference reduction, and CDMA wireless networks.
• 1998 - 1996 Project Leader of a research contract with Nortel to
model transcoding and content filtering for internet wireless browsing through
proxy servers.
• 1996 - 1998 Participant in the Federal Center of Excellence in
Telecommunications (CITR) for Broadband Fixed Wireless Systems.
• 1980 - 1999 Had 25 consulting contracts with the DOC (now Industry Canada) to conduct studies on the following issues: 3G spectral compatibility issues. Broadband CDMA systems. Broadband wireless systems (LMCS). Inter-service-interference of radio systems. Interference reduction techniques, Modeling of the radio spectrum resources. Spectrum management models. Radio specification standards for analog and digital systems. Data transmission over existing cellular radio systems. VHF/UHF radio systems. Voice/Data Integration over PSTN/Mobile radio systems. Field measurements of radio propagations in urban areas.
• 1980 - 2001 Had many consulting projects with various telecommunications industrial organizations, including: Harris Communications, Ericsson, Nortel, VISTAR, Bell Canada, Bell Mobility Cellular, INTELSAT, NYNEX, Canadian General Electric, DataRadio, NovaTel, MNET, ElectroCom Automation,Tx., KVA Electronics, Intellitech of Canada Ltd., RAM,NJ. The consulting work focuses on analysis, design and implementation of analog and digital radio sub-systems, such as: modems, adaptive interference cancellers, modelling of radio channels and mobile channel simulators.
