KitWorks.fi Ltd. today announced the 1st IP-based wireless sensor network (WSN) handheld device in the world, which interoperates seamlessly with IP-based 2.4GHz wireless sensor networks taking full advantage of the 6LoWPAN standard and IEEE 802.15.4 RF technology. The KitWrx 456 handheld tablet enhances smart object connectivity by enabling communication with 6LoWPAN based wireless networks and smart devices, along with RFID tags for enterprise applications in addition to previously used WLAN and barcode reading technologies.
The KitWrx 456 handheld tablet was been developed jointly with IPSO Alliance members (www.ipso-alliance.org), Sensinode Ltd. and the CENTRIA research center. The KitWrx 456 is enabled by Sensinode’s NanoStack™ 2.0 – the most sophisticated 6LoWPAN protocol stack solution. NanoStack 2.0 enables communication with 6LoWPAN enabled ad-hoc devices and infrastructure networks over an easy to use API. Windows CE applications on the KitWrx 456 can access the 6LoWPAN network directly. NanoStack 2.0 is available for licensing on OEM devices, giving easy compatibility with the KitWrx 456 and Sensinode NanoRouter™ 2.0 infrastructure solutions.
The Wireless Sensor Network Research group (WSNRG) has published a new article titled 802.15.4 vs ZigBee which to help people to clarify with all the communications technologies which are used in the WSN field: 802.15.4, ZigBee, Mesh protocols, 2.4GHz, 868MHz and 900MHz bands… This first document compares both *IEEE 802.15.4* and *ZigBee* technologies and explains its main characteristics.

In general, asset tracking or logistical management with RFID is very similar to applications in wireless sensor control networks. However, RFID and sensors use wireless connectivity differently.
Wireless sensor networks use small, inexpensive, wireless transceivers integrated into compact sensors that can be used to monitor a wide range of changes like temperature, humidity, vibrations and fluid levels. This data is passed via a gateway to the enterprise net.
Over time, it is expected that wireless sensor networks and RFID will integrate and that RFID systems will be extended and evolve into “Smarter RFID Tags” which can sense, act and display.
More precisely, RFID tags will not create the “Internet of Things;” they will tag the things so the things can become members of the internet.
However, because of this extended functionality and connectivity, these connected RFID tags require greater amounts of energy, and will need to be powered by batteries. At that point, it is clear that the RFID industry will be able to benefit from the ultra low power concept (and its alternative “no-batteries” capabilities) as developed by companies like GreenPeak wireless sensor networks.

Jennic announces the successful implementation and installation of the first phase of a wireless control network using a Jennic solution. It is designed to help the City of London improve control of the heating system in its renowned School for Girls (based inside the Barbican arts and residential complex) offering better comfort and prevent over-heating, helping it to meet its obligations to reduce its carbon footprint.
The system was designed and installed by employing the wireless control network developed by Control Technologies Ltd, which is based on Jennic’s 32 bit transceiver modules. Jennic’s solution was selected as the first to market system in a single chip with the combination of ample 32-bit CPU processing power, sufficient memory space, RF transceiver, and the ZigBee/JenNet network protocol stacks. The chip also provides the serial connectivity required to interface with a wide variety of Building Management Systems.
