4. Administrative Items September 2009
Ad Hoc Committee rules (per Adrian)
Introduce the ethics etc... slides in your meetings,  you should not call for essential patents
AHC,  is a "committee of the whole" of the WG - i.e. any WG member can contribute; in practice, anybody who turns up can speak
During f2f meetings,  you can hold formal votes of only the voting members of ; on a telecon you can take straw polls,  but not formal votes
Required notices

Anti-Trust FAQ -
Ethics -
IEEE Working Group Policies and Procedures -
Chair and Secretary
Chair is Rich Kennedy (Research In Motion)
Recording Secretary needed

5. Other Guidelines for IEEE WG Meetings
September 2009
Other Guidelines for IEEE WG Meetings
All IEEE-SA standards meetings shall be conducted in compliance with all applicable laws, including antitrust and competition laws.
Don’t discuss the interpretation, validity, or essentiality of patents/patent claims.
Don’t discuss specific license rates, terms, or conditions.
Relative costs, including licensing costs of essential patent claims, of different technical approaches may be discussed in standards development meetings.
Technical considerations remain primary focus
Don’t discuss or engage in the fixing of product prices, allocation of customers, or division of sales markets.
Don’t discuss the status or substance of ongoing or threatened litigation.
Don’t be silent if inappropriate topics are discussed … do formally object.
See IEEE-SA Standards Board Operations Manual, clause and “Promoting Competition and Innovation: What You Need to Know about the IEEE Standards Association's Antitrust and Competition Policy” for more details.

8. Regulatory Summary – European Union
September 2009
Regulatory Summary – European Union
ERM TG11 - EN revision
See FOCUS slides
EU Digital Dividend Consultation (Closed September 4th)
WG SE21 - Radar Spurious Emissions
EUMETNET asking for relaxation of -100dBc requirement to -60dBc
Edgard presented WFA position that EUMETNET request be rejected
SE21Chair accepted the input; indicated that the project closes in Sept 2010
WG SE24 - 5GHz RLANs OBA
RLAN community has offered to block 5600 – 5650MHz band OBA
Final report indicates 5600 – 5650MHz OBA only should be blocked
No position taken on terrestrial WLANs in this band

FOCUS: Proposal for TG11
For operation under EN rules: A technology neutral limit, based on the maximum average transmitted energy during a busy second, and assuming that peak transmit power limits are unchanged
10m W operation under EN still allowed
Rich Kennedy, Research In Motion

11. September 2009
Existing Proposal
RLAN manufacturers present during the last TG11 meeting clearly stated that the MU approach only works if duty cycle is further restricted in terms of maximum Tx-on time, minimum Tx-off time, max averaging period, etc… as otherwise a single Duty Cycled system can cause continuous interference into an RLAN system.
In order for devices to benefit from duty cycled systems, the following should be respected:
Max. Tx-on time: 0.4 mSec
Min. Tx-off time: 0.1 mSec
Averaging time: 4.0 mSec
Maximum duty cycle: 10%

12. Shortcomings of the Proposal
September 2009
Shortcomings of the Proposal
While the proposed elements of duty cycle may facilitate sharing with devices, it may still be incompatible with other technologies, especially those with modulations that do not use constant transmit power, e.g., W-CDMA systems.
Current applications in 2.4 GHz use a wide range of different technologies, each having their own needs w.r.t. maximum Tx-on time and minimum Tx-off time making it impossible to agree on a single set of values that could be beneficial for all technologies.
Rich Kennedy, Research In Motion

13. Alternate Approach September 2009
We should offer a variation of the current formula that we believe will suit not only the short range devices, but also protect devices, like devices, that have optimized active sharing mechanism
Medium Utilization = Energy in millijoules measured over any 1 second of the complete duty cycle; the limit is
MU < 4 millijoules
Examples
100 mW for 100 milliseconds (out of 1 second) = 10 millijoules
10 mW for 1 second (DC – 100%) = 10 millijoules
Compared to the current agreement, the 4 Millijoules represents a lower threshold, but on the other hand, apart from the measuring period of 1 second, no further restrictions are applied on modulation e.g. the Tx-on time and Tx-off time
Joules preferred over ‘Power x Time’ to allow non-constant envelope modulations, or technologies that operate at variable power to benefit from those transmissions where they do not operate at full power.

Conclusions
We believe that this alternative will enable the provisions of Paragraph Spectrum Sharing Mechanisms to allow SRDs to operate at higher power limits than the current limits of EN without causing unacceptable interference into Wideband Transmission Systems that have depended on EN for market access for many years.
