· Chair: Clint Chaplin, Samsung Electronics
· Call to order
· Review of IEEE Intellectual Property Policy
· Call for essential patents – None were given.
· Approved minutes for the January Session as document 11-10/0111r1.
· Presentation of document 11-10/296r1 on Heterogeneous wireless mesh internetworking by Tae Jin Lee
· The purpose of this presentation is to show that there are multiple non-interoperable mesh implementations today. It sounds like this work should be presented in TGs.
· A bridging function should be able to address the problem presented in this document.
· The key messages are:
· We need to complete TGs.
· We need vendors to adopt TGs to resolve this issue.
· Presentation of document 11-10/287r3 on carrier grade WLAN at Disney Theme Parks by Stefan Mangold.
· There is a conflict in requirements between minimizing AP’s and High Throughput.
· Most of the traffic is broadcast. However more than one access point would likely be needed to cover the entire park.
· Could WiMAX be used? It would be hard to put a WiMAX radio in a Toy.
· There was no real analysis done on specific PHY types. The focus was on the solution technical requiremensts.
· An application could be architected that would take into account Wi-Fi/Cellular handover. In this way Wi-Fi can be used for high bandwidth and cellular for coverage.
· The issue with Wi-Fi today is that it is too difficult to handle registration and authentication.
· Dual-band operation could be used for different types to mix licensed and unlicensed.
· A scheme could be used where one band could be used for DL and another used for UL. That is the basis for the mechanism presented in this document.
· Introducing FDM will not be backward compatible and will add some cost to the device.
· An IEEE 802.11 MAC based on FDM would be cheaper than LTE.
· TVWS would not work in Disney World.
· Stefan will come back to WNG with an updated proposal.
· Presentation of document 11-10/204r1 by Dave Halaz on sub-1 GHz license-exempt operations.
· With a 5 MHz wide channel, the bandwidth would be around 1 Mb/s, which is similar to 802.15.4g.
· This PAR will scale the bandwidth and channel widths in the ISM bands to deliver higher rates.
· Could the PAR be renamed from sub-1GHz to 900 MHz? The name was changed in response to another comment.
· The Study Group is a candidate for approval during this session by ExecCom.
· Presentation of document 11-10/361r0 on Fast Initial Authentication by Hiroki Nakano
· There will be a follow-up presentation during the closing plenary. The presentation will be less technical.
· This idea would modify initial association protocol to improve the time taken for initial association.
· At some point, there will need to be a motion to form a study group.
· There is some interest in creating a Study Group to look into this problem.
· Presentation of document 11-10/368r0 on Heterogeneous Wireless Networks Mgmt by Johannes Wiessman
· This work is being done to address heterogeneous mesh networks.
· The required protocols are already defined in IEEE 802.11 to support this study group. IEEE 802.11 members are encouraged to participate.
· In solutions today, EAP-SIM is already is supported at L3, but not L2. This study group provides signalling for heteropeneous networks. The IETF IFON (IP offload) only assumes the network is in a trusted domain.
· There is no real traffic offload. This work provides network signalling for heterogeneous networks. The IP network could be overlayed in any appropriate manner.
ORDERS OF THE DAY. The WNG SG is adjourned.
