Agenda Commercial Product Open Source Solution Further Application

Commercial Product (1/4) Linksys – WRT54G3G

Commercial Product (2/4) BCM4712 integrated network processor 4 ports switching hub Support limited 3G/UMTS NIC OpenWRT ( have several hack for additional functionhttp://openwrt.org 3.5G is support by particular firmware and T-Mobile/Vodafone 3.5G card

Commercial Product (3/4) Mobilized Application (credit: Custom) In-car power adapter

Commercial Product (4/4) Mobilized Application (cont.) Extensible high-gain antenna

Open Source Solution (1/2) MobiWall – A variant of m0n0wall Software aspect  A middle ware and wrap-up for 3G/3.5G NIC operation  Most of works are done by AT-command set Hardware aspect  Soekris NET-4521 Single Board Computer  2 cardbus slot, one for WiFi, one for 3G

Open Source Solution (2/2) Tested 3G NIC on MobiWall prototype  Fusion/Option (GlobalTrotter) UMTS  Fusion/Option (GlobalTrotter 3G+) 3.5G  Sierra AC G

Further Application Provide wireless connectivity on mobile vehicles is possible Open source solution can also put more flexible on development and deployment issue
