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 Division Multiplexing (WOFDM),[1][2] and Multi-code Direct-sequence Spread Spectrum (MCDSSS)[3]. 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[4][5][6]. Currently, Dr. Zaghloul is the CEO and Chairman of IPL Media Inc. for Technology, Giza, Egypt, a company specializing in providing web development services as well as developing and marketing mobile games. He co-founded with Dr. 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.

Biography

edit

He was born on February 7, 1957, in Giza, Egypt. At the age of 22, he received a B.Sc. in Electrical Engineering from Cairo University. He did the third year of an applied math 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 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.

Awards

edit
  • Received the 2000 Fraser Milner Casgrain Pinnacle Award for his entrepreneurial achievements[7].
  • He was presented with the Hall of Fame Award from Broadband Solutions on April 10, 2000, for his contribution to the communications technology industry[8].
  • Receipient of the Calgary Immigrants of Distinction Award Recipients for business in 1998[9].
  • Designated by Canadian Computer Wholesaler Magazine as "Technically Excellent Canadian" in July 1999[10].

WiLAN Inc.

edit

Based on his patents in WOFDM (Wide-band Orthogonal Frequency Division Multiplexing) he co-founded Wi-LAN Inc. in 2001. Through Wi-LAN's efforts, the Federal Communications Commission (FCC) allowed OFDM technology over the 2.4GHz unlicensed ISM band for the Institute of Electrical and Electronics Engineers (IEEE) 802.11 standards, better known as the Wi-Fi standard[11]. Another technology developed and patented by Dr. Zaghloul and Dr. Fattouche is MC-DSSS (MultiCode-Direct-sequence Spread Spectrum) which is central to high speed CDMA applications, the main technology currently used by more Cell phone systems in North America than any other technology. Wi-LAN and Philips invited companies to attend a meeting to form an alliance to promote the OFDM technology and its applications. Fifty five companies attended the meeting in November 1999 and formed the OFDM Forum in March 2000. WiLAN also was a founding member of the WiMAX Forum together with Ensemble, CossSpan, Harris, and Nokia.

Interestingly, for marketing purposes, WiLAN acquired 49% of the original patent on frequency hopping spread spectrum from legendary actress Hedy Lamarr in 1997. It was Lamarr's only compensation for her invention[12].

Wi-LAN's Awards

edit
  1. WiLAN won the 1998 ASTECH Award for "Small Business".[13]
  2. WiLAN was one of four finalists for the 1997 ASTECH Award for "Small Business".[13]
  3. WiLAN won the 1993 Electronics Industries Association of Alberta (EIAA) "Award for best technology".[13]
  4. WiLANis the 1999 recipient of the CATA Alliance Award of Distinction for Emerging Technology[14].
  5. WiLAN a Wireless Communications Association (WCA) International "Wemmie" in the "Most Effective Educational Program" category for the Northern Lights School Division network in Northern Alberta[15].
  6. WiLAN received the Export Achievement Award from Alberta Venture Magazine in 2004[16]
  7. WiLAN received the Alberta Professional Engineers, Geologists and Geophysicists Association 2002 APEGGA Achievement Award for substantial technological progress[17].
  8. WiLAN won the 2004 Calgary Export Achievement Award for Collaborative Partnerships by the Haskayne School of Management[18].
  9. WiLAN was awarded a Wireless Communications Association International "Wemmie" Award in 2003[19]. The award was for the Banco Del Pichincha non-line-of-sight network in Ecuador.

Press coverage

edit

Dr. Zaghloul was named as one of ten great Canadians by McLean's magazine in July 2000[20]. Dr. Zaghloul has been named "Calgarian of the Year" by Business in Calgary magazine in 2000[21].
