Why IEEE 802.21?• It offers media independence• It specifies many of the needed primitives already• It offers the required communication mechanisms• However, there are still points missing to enable
wireless network management and some new primitives would be needed

wireless access capacity triple-play QoS requirements
“Emergency Response Support”, proposed by DT severe capacity constraints intermittent connectivity to core network sub-optimal node placement focus on group-communication

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
doc.: IEEE 802.11-10/0368r0
Submission
Conclusion• Heterogeneous wireless networks are a
promising solution in a number of use cases• Required functionality is covered to a large
extent by IEEE 802.21 due to its media independence
• Consortium of companies/research institutes have investigated and are currently implementing a heterogeneous backhaul using IEEE 802.21 extension, i.e. media independent link interface
• 802.11 is one key technology in a heterogeneous networks context
