9. Why IEEE ?
It offers a media independent interface (MIH_SAP) already
Many of the primitives defined in for handovers can actually be reused for network management/cross-layer information exchange
It offers the required communication mechanisms (e.g. to propagate link state updates to a central mgmt. entity)
Obviously, there are still points missing to enable wireless network management and some new primitives would be needed

15. LinkNet Macha Project in Zambia
Villages and the houses within those villages are scattered across a large land
No wired communication
No reliable power supply
Limited hardware resources
Limited budget
Target: Deploy a country-wide heterogeneous wireless backhaul which is reliable enough to provide affordable connection throughout the country
First devices have been deployed by Fraunhofer Institute in September 2009

16. Current Status two main items under consideration
Collect use cases and contributions from wider industry
Develop a common understanding of PAR scope
Re 1. ongoing (offline) discussions with several companies
Past contributions
Telcordia, Intel, China Mobile
Confirmed contributions
MediaTek, Toshiba, Proximetry
Potential future contributions
ETRI, InterDigital, Beceem, DT, Aveiro IoT
