MINUTES

|1.00 | |MEETING CALLED TO ORDER |Sherman |1 |01:00 PM |

The meeting was called to order by the 802.WS Chair Matthew Sherman at 1:00 pm. He welcomed the attendees to the meeting.

|2.00 | |ATTENDENCE |Sherman |5 |01:01 PM |

The Chair requested all participants without access to webex to send their name and affiliation info to the reflector noting that they were on the teleconference. He also asked those on webex to add their names to the chat section.

|3.00 |MI |APPROVE OR MODIFY AGENDA |Sherman |5 |01:08PM |

There were initially no comments on the agenda and no objections to approving the agenda. However, upon further review, there was a request to change the sequence of discussion point (See below).

|4.00 |II |REVIEW IEEE PATENT POLICY |Sherman |5 |01:09PM |

The Chair asked if anyone had not reviewed the patent policy for this call. No one responded that they had not reviewed it.

|4.01 |II |Review purpose of ECSG and Teleconference |Sherman |5 |01:10 PM |

The Chair presented slides from the presentation on EC Study Group on TV White Space () to explain the formation of the ECSG. This ECSG will not develop a PAR and 5 Criteria. Rather it will make recommendations to the EC regarding future activities.

Apologies to those in parts of the world where the timing of the call is inconvenient.

Action Item: The Chair will review the teleconference schedule to see if it could be put on a rotating basis.

|4.02 |II |Review format and procedures for teleconferences |Sherman |5 |01:12 PM |

The size of the conference call makes it important to use webex. The Chair requested that participants raise their hands to get the floor. Went through an example to demonstrate this feature. There were no further questions about webex.

|5.00 |DT |Discuss How best to address tasks assigned to the ECSG |Sherman |10 |01:16 PM |

The group reviewed the six sub items on the agenda, the Chair suggested spending ten minutes addressing each of them. Peter Ecclesine requested a change in sequence, to instead begin with 502, 503, 501, then 504, 505, 506. The Chair asked if anyone objected to this change in the agenda. There was no objection.

|5.02 |DT | Identify Use Cases of TV White Space Spectrum |Sherman |10 |01:20 PM |

The Chair requested contributions to outline use cases and suggested that the activities of industry associations might be leveraged.

Places where use case information could be found include:

NAF – New America Foundation

WIA – wireless innovation alliance

Smart Grid – for metering

802.11 – reference document # 1439rl

802.15.6c – Body Area Networks, channel models indicate that frequency is very good for this set of apps, document # 15-08-0407

SENDORA project – 5 use cases have been defined

Action Item: Sudhir Kumar Baghel will distribute SENDORA document

The White Space Coalition - Google, HP, etc had define fixed and portable as the basic headings. Use cases that the White Space Coalition had referenced included home networking, i.e video and long range WiFi. The latter refers to apps similar to WiFi but with the extended range enabled by the frequency spectrum.

FCC 04-186 contains the preceding of relevant lobbying efforts. There are approximately 39K documents. Therefore it is not feasible to extract the use cases that may be contained within them.

Action Item: Kursat Kimyacioglu will distribute the exparte filing from Philips.

For fixed applications, 802.22 has developed a reference model.

Action Item: Gerald Chouinrd will provide this and additional input regarding an article in Communication magazine.

The SDR Forum has developed use cases. Pat Carson with TDK and Joe Mitola from Stevens Tech are the contacts.

The Chair asked for a volunteer to makes contributions to summarize and outline these use cases, and lead ad hoc meetings.

Action Item: Nanci agreed to spearhead efforts in this area.

|5.03 |DT | Identify what functions may be common across 802 technologies |Sherman |10 |01:35 PM |

The Chair expressed the intent to identify those aspects that should be standardized.

All protocols will have to implement various policy and policy interfaces. Can be implemented via on line data base. Need to determine which would apply to process the database. 802.22.2 defines a recommended practice for a database interface.

Spectrum users need to access database and get the frequencies where they can operate. That work doesn’t belong in a recommended practice. Should be an actual standard. Could be common across all of 802. It’s not just a database, it has to put policy in place to perform processing. Mandatory for fixed and portable devices. Sensing is part of the policy and has to be included in the engine. Are there things that could have a common definition. Don’t have to apply them universally.

The meeting was interrupted, all logged off at 1:45 to allow AT&T to add more ports and resumed the call at 1:50.

If going to have a common engine, not only database standardized but language or syntax must be common. Policy engine is the term in use. Language of the policy engine needs to be standardized. 1900.5 is working in this area. 1900.5 liason might be helpful for this process. SCC 41 is sponsor for 1900 WGs. Desirable to establish a formal liaison.

Action Item: Joanna Guenin who is the Chair or SCC 41 tentatively agreed to share the liaison position between SCC 41 and the Whitespace ECSG with Dan Lubar who will back her up. Dan is a voting member of 1900.6.

Discussion occured on standardization of a common sensing approach. Sensing not centralized, millions of sensors trying to feedback to the database. Database is mandatory. All incumbent and whitespace devices must be sensed. The technique does not need to be standardized; however, reporting structure could be standardized. 1900.6 is working on this.

Concern was expressed that sensing could result in denial of service. The Chair instructed that discussing specific approaches was out of scope, the objective for this activity was to determine where a standard might be useful.

Any other areas for standardization? Multiple access approaches, so different technologies don’t interfere with other. Fair sharing between protocols of spectrum in the white space.

Works best to get someone to spearhead this effort. The Chair asked for volunteers. No one stepped forward at this time.

|5.01 |DT | Assess the impact of the FCC White Space R&O on IEEE 802 activities |Sherman |10 |02:06 PM |

The Chair asked Peter Ecclesine to lead the conversation. This doesn’t impact just wireless, but wired standard as well since access to the internet would be over both types of connections. Issues include security each station acting as the master. Database process will exist that lists the protected services. Also list of available open channels.

There is less available white space in metropolitan areas than more in rural areas. Have to work within Part 15 except for experimental licenses. How often does database have to be refreshed? Daily or every time you access. Within a minute if a device moves.

Applies broadly across 802 but need a specific list of capabilities that need to be addressed. Impact to 802.22 has been considered. The GERDECS doc identifies some items. Must provide goeolocation is some areas depending on requirements. Who in 802.22 can provide inputs on what has been done..

Action Item: Gerald Chouinrd to provide a pointer to key docs and will forward contribution numbers for 802.22 for security work.

The document number for the GERDCS presentation is: 22-08-0206-01-0000-i-reede-amerisys-com.pdf.

Can we do something like that for 802.11? Rather than a dedicated task group, Peter Ecclesine suggested it might be possible to accomplish any required modifications by inserting comments into ballots to cause them to be addressed.

|5.04 |DT | Begin technical discussion on how to enable coexistence between various |Sherman |10 |02:21 PM |

| | |802 technologies in the shared TV white space spectrum | | | |

Steve Shellhammer opened the discussion. We are developing multiple standards within 802. We need to investigate what kind of changes would be required to make them co-exist? How easy or how intrusive to the standard? Another question is, how likely is that these different standards are going to be implemented in the same area where we need to start worrying about coexistence.

The group discussed three aspects of interest: sensing, coexistence, and self-coexistence.

Recent presentation made in 802.19 to address coexistence between 80.11. and 802.16.

If FCC comes up with rules for high power use, this will impact IEEE 802. Presentation in 802.18, document #40 from July 2008 is of interest.

|5.05 |DT | Prepare a Tutorial for March Plenary |Sherman |10 | |

N/A

|5.06 |DT | Make recommendations to 802 EC by March 2009 on next steps |Sherman |10 | |

N/A

|6.00 |  |ADJOURN TELECONFERENCE |Sherman |  |02:30 PM |

Wrap up discussion. Did not have time to address 505 or 506 and will lead off with those on the next call in two weeks. Any contributions that we give to the EC would be approved by this study group. The Chair encouraged participant to have some adhocs.

We will have a deadline for comments to the FCC on the R&O. Deadlines are 30 days for the comment period, amd 30 days to respond to comments after published. Therefore, we only have two or three teleconferences to work on this. 802.18 is having an emergency ad hoc to respond to the FCC and is waiting for input from 802.22. 802.22 has to formulate a reply within 20 days after publication, when the clock starts, since 10 days will be needed for .18 to work on it. 802.22 will start discussion on this Thursday.

Steve Shellhammer volunteered to be vice chair for this study group. No other volunteers. We will have a vote on this during the next teleconference but are open for other volunteers.

Action Item: The Chair will send an email to notify participants of the upcoming vote.

Dan Lubar will act as secretary for next telecon. Steve is going to lead some coexistence ad hocs and welcomes participation.

Adjourned at 2:37pm.
