• The world's first urban White Space Network (2003-): Led a small team of researchers that built and deployed the world's first White Space Network (on October 16, 2009). Authored Microsoft's proposal for spectrum etiquette (2003). Published several papers, started conferences & workshops (e.g. DySPAN, INFOCOMM Workshop), edited special issues (IEEE J-SAC), wrote book chapters, gave over a dozen keynotes and plenaries, developed prototypes, influenced pgovernment spectrum policy (FCC Panels, demos to TRAI, SARFT, ANATEL & FCC filings) & government research funding (NSF workshops) etc. Had a hand in the Nov. 4, 2008 FCC ruling that has opened up 180 MHz+ of spectrum for unlicensed devices in the United States.
• Enterprise & Home Network Management (2005-): A unique end-to-end approach for managing networked applications and services in large enterprises. This approach requires end-hosts to cooperatively detect, diagnose, and recover from network performance problems. Unlike existing products, end-hosts gather, aggregate, and analyzing data at all layers of the networking stack to determine the root cause of the problems impacting applications and services. The work (netHealth) includes several projects in the wireless and wired network management.
• The world's first multi-radio single network system (2003) Introduced important new design ideas on using multiple radios to improve the performance of wireless mesh networks, wireless LANs, and cell phones. These designs have proliferated deeply into the computer and telecommunication industry. Awarded multiple patents and received considerable coverage from mainstream media for this work.
• The world's first wireless network virtualization architecture (2002): this architecture enables a network card to connect to multiple networks simultaneously. Software downloads exceeded over 100,000 making it the second most popular download in Microsoft Research's history (up until 2007). It is being shipped to millions of users via Windows 7. Received many accolades from main stream media. The design is fundamental to NSF's GENI WLAN virtualization efforts.
• The world's first public Wi-Fi hotspot network (2000). Deployed the network in Bellevue, Washington from 1999 to 2001 (New York Times Article, Feb. 28, 2000). The wireless edge server design is being used by all the major Wi-Fi equipment vendors, beating out the competing IEEE 801.1x design. Awarded 5 international patents and considerable favorable press coverage. (Click here to check out the original web site, June 1999)
• The world's first Wi-Fi based indoor location determination system (1999). Original paper has been cited over 2300 times and in large part has created the field of indoor positioning systems using commodity hardware. Several companies including Ekahau, Symbol, Nortel, Intel, Cisco, and Microsoft have commercialized versions of this system and many universities are using it as a foundation for research in location and context aware systems. Awarded 9 U.S. and international patents for this work. (Click here to see original demo, April 2000)
• The world's first commodity multimedia hardware adapter for PCs (1992). The hardware had real-time audio-video coding/decoding and image rendering capabilities. It was used world-wide for research in high-speed (ATM, FDDI) and packet video networks (Sequoia 2000, BERKOM, BAGnet & MBONE)
• Community mesh networking (2003), Popularized this networking paradigm as an alternative technology for broadband access in cities, neighborhoods, offices, and rural areas. Helped create the Digital Inclusion Program that provided $1.5 million in research funding. Developed the Academic Resource Kit 2005 & 2007 for teaching & research. The kit is being used by over 1200 Universities world-wide. Gave keynotes and taught several courses. Published multiple papers, awarded 8 international patents, received wide press coverage, and licensed out the technology to start-up companies.
• Contributed to multiple wireless networking standards: The IEEE 802.11e standard incorporates ideas from the distributed weighted fair scheduling algorithm that we invented. The IEEE 802.11s mesh standard incorporates abstractions related to multiple radios and fast channel switching. The Bluetooth SIG's Local Positioning WG incorporated the signal strength matching techniques that we invented. The NativeWiFi and Wireless Zero Configuration in the Windows are derivatives my work.
