• Cellular Edge/GMS/GPRS
• Data/Telecom networks 10G Ethernet VoIP
• Wireless LAN claim to ship industry's first
  standards-based for 802.11g wireless LANs with
  performance enhancements 78 percent of market
  share in 2003
• Many other products

6
Technical Contribution

• The largest share of market for 802.11g
• The fasted 802.11g/e (according to
  http//www.extremetech.com/article2/0,1558,1499139
  ,00.asp)
• achieve 125Mbps
• interoperable
• Use Xpress technique, based on packet (or
  frame) bursting techniques.
• Key idea puts more data into a single
  transmission, thus reducing the overhead

• Point out the problem of interoperability
• In 2003, Broadcom's claims that Atheros's Super
  G mode interferes with Broadcom's 802.11g
  chipsets. This might make compatibility and
  interoperability the number one issue in 2004.
