1. Wireless SolutionsSimplifiedwww.helicomm.com IPv6 Over IEEE 802.15.4 IETF ‘6lowpan’ BOF Session 10 November 2004

2. Wireless SolutionsSimplifiedwww.helicomm.com Helicomm Overview Provide Standards-Based Wireless Systems –IEEE 802.15.4, ZigBee, IPv6 Leading Embedded Wireless Networking Platform –Embedded modules –Network gateways –Networking software & tools Well Positioned in Several Key Global Markets –Home Control –Meter Reading / Utilities –Defense / Security Chinese President Hu Visits Helicomm-Beijing

3. Wireless SolutionsSimplifiedwww.helicomm.com IPv6 Motivations Why IPv6? –Rapid growth in networked devices throughout Asia Additional network address space, IP compatibility –Selective demand in US & EU for IPv6 feature set Zero configuration, network self configuration Why Helicomm? –Strong market presence in Asia Deploying one of world’s largest Wireless Home Control solutions with Haier –Customers looking for integrated solutions (technology agnostic) Modules, networking software, gateways (optional), tools View ZigBee & IPv6 as Complementary –ZigBee for system interoperability & large / complex hybrid networks –IPv6 for IP back-office system compatibility & proprietary applications

4. Wireless SolutionsSimplifiedwww.helicomm.com IPv6 Application Scenarios Home Control –‘Wireless Lifestyle’ for integrated IP-based wireless solution (e.g,. Haier) –Standalone products that do not require / can not afford ZigBee gateway AMR –Primarily for Commercial & Industrial electric meter aggregation –Current customers use GPRS & paging network for WAN Security –IP-based video monitoring solutions commonplace (e.g., Sony) –IP-based wireless image capture / low rate video a natural fit Other –Access Control (leverage existing IP infrastructure) –Parking Meters (integrate with IP-based WWAN)
