The DASH7 Alliance, a non-profit industry consortium that promotes wireless sensor networking standards, today announced the public release of the DASH7 Alliance Protocol.
DASH7, an open source wireless sensor networking standard, competes with Zigbee(900MHz/2.4GHz), Z-Wave (900 MHz), Bluetooth (2.4GHz), WiFi (2.4/5 GHz), and Low Power UWB for machine to machine communications, but features multi-kilometer range, excellent penetration of walls, floors, and water, operates on extremely low power and features multi-year battery life with a maximum bitrate of 200kbps.
Operating in the license-free 433.92 MHz spectrum, DASH7 offers multi-kilometer range, multi-year battery life, sensor and security support, as well as tag-to-tag communications, achieved through ad hoc-synchronized communications. The new protocol is built on the IEC 18000-7 standard and provides seamless interoperability.
“A distinct capability of the protocol provides for both infrastructure to endpoints (RFID tags) and endpoint-to-endpoint communications, while operating from a battery and maintaining low power operation”, said Michael Andre, chairman of the Dash7 Alliance.

Weightless, the global organisation delivering the royalty-free open standard to enable the Internet of Things, today announced the release of version 0.9 of its innovative M2M Specification. Weightless enables M2M systems featuring a chipset cost of less than USD$2, a range of up to 10km and a battery life of 10 years.
The announcement follows the recent announcement of growing support and momentum for the standard with the appointment of ARM, Cable and Wireless Worldwide, CSR and Neul to the Board and Promoter Group.
Weightless is the Special Interest Group (SIG) and the name of the wireless wide area global standard for machine to machine short to mid-range communications.
With the release of version 0.9 the Weightless Specification moves within a single step of a final, stable v1.0 release due towards the end of Q1 2013. Version 0.9 is now complete with significant additions made to the MAC, Security and Applications sections. On the MAC, significant detail has been added to areas such as handling of alarm events, initial network selection and the entire set of channels has been re-grouped and re-named in a more logical and consistent way. On security all aspects of encryption have been detailed and the setting of Master and Subsidiary keys has been fully defined along with details of their storage and transport. On applications a complete protocol for application to MAC interfacing has been produced and linked carefully into MAC features and requirements. The specification is now over 300 pages long and provides all the detail needed for developers to fully understand and model it.

The Internet of Things is supposed to connect every aspect of our lives from our homes and cars to the objects we wear and the goods we consume. It’s even connecting ice machines. But one thing the Internet of Things lacks is a unifying standard.
Devices will be connected by different radio technologies: Wi-Fi, Bluetooth, ZigBee, and a host of 2G and mobile broadband cellular technologies. There’s really no way of assuring your ‘thing’ will connect to the network or networks available at any given time.
The mobile industry is trying to rectify the problem at least as it pertains to cellular machine-to-machine (M2M) technologies. The bigger issue of fragmentation between bands and technologies isn’t going to get worked out anytime soon — you’re not going to connect a GSM wristwatch to a CDMA or Wi-Fi network. But often you can’t connect that GSM wristwatch to a GSM network either. Roaming between networks that use the same technology requires not only a business arrangement with each carrier, but a common protocol.
A group of global wireless standards bodies are trying to tackle that problem. The European Telecommunications Standards Institute (ETSI), the Telecommunications Industry Association (TIA) and the Alliance for Telecommunications Industry Solutions (ATIS) in the U.S. are working with their counterparts in Japan, Korea and China to develop a common “service layer” which can be embedded in every M2M device, making them compatible with M2M application servers hosted by any global operator.
