Hatim Zaghloul (Arabic: حاتم زغلول, Egyptian Arabic, born February 7, 1957) Ph.D., M.Sc., B.E.E. is best known for his inventions, together with his long-time friend, Dr. Michel Fattouche of Wideband Orthogonal Frequency Division Multiplexing (WOFDM), and Multi-code Direct-sequence Spread Spectrum (MCDSSS). WOFDM is the foundation for the IEEE 802.11a/g/n technologies whereas MCDSSS helped increase the data rates of code division multiple access (CDMA) technologies as in the CDMA2000 standard. Currently, Dr. Zaghloul is the CEO and Chairman of Inovatian Inc., Giza, Egypt, a company specializing in building wireless data networks in unconnected countries through WiFi and blockchain. Dr. Zaghloul is also the Co-founder and Chairman of Hikmah Capital Ltd. a company specializing in the development, marketing and management of financial technology solutions., Calgary, Alberta, Canada. He co-founded with Michel Fattouche, to commercialize their patented WOFDM technology. He founded and co-founded a number of hi-tech companies such as Cell-Loc Location Technologies Inc., a company he co-founded with Michel Fattouche to commercialize a cellular telephone location determination/tracking technology.
He was born on February 7, 1957 in the Giza, Egypt. At the age of 22, he received a B.Sc. in Electrical Engineering from Cairo University. He served in the Egyptian Armed Forces during 1980. That year he completed the third year and the mid-term for the fourth year of an applied mathematics degree in Ain Shams University, Cairo, Egypt. He worked for Schlumberger Wireline Services as an oil well logging engineer from 1981 to 1983. He was a Teaching Assistant at the University of Calgary from 1984 to-1989. He obtained his M.Sc. in physics from the University of Calgary in 1985. He was a Statistics instructor at the University of Athabasca from 1988 to 1990. He was a senior researcher at Telus from 1989 to 1993. He obtained a Ph.D. in physics from the University of Calgary in 1994. He held various positions in Wi-LAN Inc. from 1993 to 2008. He was the CEO of Cell-Loc Inc. from 1995 to 1997. Dr. Zaghloul was on the board of directors of many hi-tech companies. He was the CEO of Solutrea from 2006 till 2008.
He is currently the Chairman and CEO of Inovatian Inc., that was incorporated in 2016 in Giza, Egypt, as a research and development company specializing in telecommunications and electromagnetics. Inovatian has since led the development of a 6G standard through the 6G Forum.
- Received the 2000 Fraser Milner Casgrain Pinnacle Award for his entrepreneurial achievements.
- Dr. Zaghloul was a finalist for the Ernst and Young Entrepreneur of the Year award for two years: 1997-1998.
- He was presented with the Hall of Fame Award from Broadband Solutions on April 10, 2000, for his contribution to the communications technology industry.
- Recipient of the Calgary Immigrants of Distinction Award Recipients for business in 1998.
- Designated by Canadian Computer Wholesaler Magazine as "Technically Excellent Canadian" in July 1999.
- Named one of 10 Great Canadians by MacLean's Magazine in July 2000.
He collaborated on many patents in wireless communications, signal representation and estimation. Based on his patents in WOFDM (Wide-band Orthogonal Frequency Division Multiplexing) he co-founded Wi-LAN Inc. in 1992.
In 1997, Dr. Hatim Zaghloul learnt that Hedy Lamarr was never compensated for her invention of frequency hopping spread spectrum. He contacted Hedy Lamarr and signed an agreement giving Wi-LAN Inc. 49% rights to her patent for marketing purposes at an undisclosed sum. He worked with Hedy till her death in 2000 to promote the patent and establish its value.
Other business activities
Based on his collaboration with Dr. Fattouche on Super-Resolution, Dr. Zaghloul also co-founded Cell-Loc Inc. in 1995 (which became Cell-Loc Location Technologies Inc. in 2003), the developer of a family of network-based wireless location products that enable location-sensitive services of people and assets using a small portable device. In 2005, he cofounded with his friend, Dr. Syed Amr Elahamasy, Innovative Products for Life Inc., a technology commercialization company. Their first product was an attachment for commercial blenders that would remove grease from fried foods. This work has led to a patent on the technology. Over the years, Zaghloul joined the boards of many companies: NTG Clarity Inc. from 1997 to 2001, Imaging Dynamics from 2000 to 2001, Powerstar International Inc. (and Solutrea Corp.) from 2007-2008. QCC Technologies from 1999 to 2001, IPL Media Inc. for Technology from 2009 to the present.IPL Media was incorporated in 2005 in Alberta, Canada.
He has been mentioned in many online and print articles over the past decades.--> Dr. Zaghloul was named as one of ten great Canadians by MacLean's magazine in July 2000.
Dr. Zaghloul has been named "Calgarian of the Year" by Business in Calgary magazine in 2000.
