Arch Rock and Hitachi Demo 6LoWPAN Interoperability with Renesas at December IETF Meeting

Demo is First to Show Multi-vendor 6LoWPAN-Attached Devices Communicating Across Internet

SAN FRANCISCO, Calif., Dec. 4, 2007 – vendor Corp. has joined with Hitachi, Ltd., and Renesas Technology Corp. to demonstrate the interoperability of their IETF (RFC 4944) implementations at the Seventieth IETF meeting today in Vancouver.

The demo shows Arch Rock's and Hitachi's implementations of IETF 6LoWPAN, the recently finalized standard for IPv6 communication over low-power IEEE 802.15.4 personal-area networks. Arch Rock is providing its Primer Pack/IP wireless sensor network, announced in March 2007 as the first commercial product to implement the IETF 6LoWPAN standard; Hitachi's 6LoWPAN implementation is running over 802.15.4 radio chips from Renesas.

While previous interoperability demos have shown multi-vendor wireless sensor nodes on the same local 6LoWPAN network communicating with each other, this is the first to show multi-vendor 6LoWPAN-attached devices communicating over the Internet – both with each other and with other non-sensor IP devices, such as Ethernet-connected PCs or WiFi-connected laptop computers.

Arch Rock CEO Roland Acra said, "This demo showcases the power of the 6LoWPAN standard to make full Internet citizens that can be accessed and managed just like any other IP devices – and can communicate with other IP–enabled devices anywhere in the world. With the adoption of 6LoWPAN by leading vendors such as Hitachi and Renesas, the industry is recognizing the importance of standard, open communication that non-IP 'standards' in the past have failed to achieve."

About the IETF 6LoWPAN Standard

The IETF 6LoWPAN standard defines how IP communication is conducted over low power wireless IEEE 802.15.4 personal-area networks; it utilizes IPv6, the latest and most scalable version of the ubiquitous Internet Protocol. The IETF 6LoWPAN working group was formed in 2004 to address the challenge of enabling wireless IPv6 communication over the newly standardized IEEE 802.15.4 low-power radio for devices with limited space, power and memory, such as sensor nodes. Among the group's challenges were developing a practical means of compressing IP's powerful addressing and header information to fit into small packets whose transmission would consume minimum energy, and accommodating efficient multihop routing over IEEE 802.15.4 mesh networks.
