The IP500 Alliance is an interesting standards alliance, focused on creating an open standard for wireless systems in smart buildings.
According to their site:
The IP500® Alliance is an international industry initiative launched by leading manufacturers, users, and operators. It has set itself the target of jointly defining, developing, and providing a secure and vendor-neutral wireless communication platform for smart buildings. The new IP500® platform will thereby fulfill all of the technical requirements for secure, interoperable, and cross-disciplinary networking of smart devices for use in all areas of building automation.
The focus at the IP500® Alliance has for several years been on close collaboration with all Alliance members on a joint solution. By using central, generally used and accepted industry norms and standards such as IEEE 802.15.4, IPv6, 6LowPAN, BACnet, AES128, and IPsec, it guarantees maximum interoperability for vendor-neutral and cross-disciplinary interaction between different products required for comprehensive building automation. Manufacturers, users, and operators benefit in equal measure from this inter-disciplinary, joint approach.
It has actually been around for quite some time:
The Alliance was founded in 2007 as an interest group and has since been able to enlist the support of numerous international cooperation partners for its work. They include companies such as Bosch, Honeywell, and Siemens. The IP500® Alliance’s initiator and President is Helmut Adamski, a longstanding and experienced CEO of several international enterprises active in wireless technology and building automation. In 2011 the IP500® Alliance was registered as a society in Germany and has so far more than doubled its membership.
