Introduction
The ANA is responsible for administering numbers as described in 11-09/0002r4 ( OM)
11-09/0031r13 is the latest ANA database and indicates that the Type subfield of the MPDU Control Field value 11 is:
Reserved for ANA
frozen for due consideration by WG of an escape mechanism
Draft P802.11ad_D1.0 has used one subtype of this value for its own purposes
This presentation is intended to stimulate “due consideration” of this use so that the response of the ANA to any request from TGad can be determined

4. November 2010
Draft P802.11ad_D1.0
Defines type=11 as extension, and subtype=0000 as mmWaveBeacon
Defined in response to .11ad’s need to have a beacon frame with the absolute minimum of overhead
In .11ad, the effective beacon rate for a typical configuration (32 antenna elements) is <1 Mbps; i.e., 3000 times lower than the data rate needed for HDMI (3Gbps)
Extension type implicitly inherit rules from (General frame format)

Editors’ Recommendation
Editor’s meeting reviewed this topic on Tuesday.
The editors recommend to open up type=11, subtypes 0-3 for allocation;
and to reserve other subtypes to allow for future TBD enhancements, e.g., to distinguish protected extension frames from non-protected extension frames.

Straw Poll
Open MAC control field, type=11, subtypes 0-3 for allocation. Reserve subtypes 4-15 for future WG discussion on use.
Yes No
