Leaders from Intel and Cisco are trying to start up an effort to standardize 802.11 mesh networking : This is a great idea, but one that not surprisingly isn't supported by current developers of mesh networks. Those companies, including Strix, Firetide, and BelAir argue such an effort would be too difficult. They might prefer not to have standards so that customers must buy entire networks from one vendor.
Intel apparently is working on a mesh standard that could span 802.11 and ultrawideband networks. That sounds like quite a challenge.
