IEEE 802.21 Comments on 802.11aq PAR and 5C Month 20xx doc.: IEEE 802.21-02/xxxr0 IEEE 802.21 Comments on 802.11aq PAR and 5C XXXX, His Company

Month 20xx doc.: IEEE 802.21-02/xxxr0 PAR- Section 5.2.b Scope of the Project: “This amendment defines modifications to the IEEE 802.11 standard, above the physical layer (PHY), …” Comment: Does this mean it could be done higher than MAC layer? Would suggest to revise as follows: “This amendment defines modifications to the IEEE 802.11 standard, at the MAC layer, …. XXXX, His Company

Month 20xx doc.: IEEE 802.21-02/xxxr0 PAR- Section 5.2.b Scope of the Project: “ .. enable delivery of pre-association service information discovery by IEEE 802.11 stations (STAs).” Comment: ‘delivery of pre-association service information discovery’ is a bit confusing. Suggest to delete the word discovery after information. In addition, will ‘pre-association service information’ be delivered securely? If not, it should clearly state it. XXXX, His Company

PAR- Section 5. 4 5.4 Purpose: “This standard also offers regulatory bodies a means of standardizing access to one or more frequency bands for the purpose of local area communication” Comment: Not clear what is to do with the regulatory bodies here? Is this requirement came from regulatory bodies?

Month 20xx doc.: IEEE 802.21-02/xxxr0 PAR- Section 5.5 Need for the Project: “This amendment would look at basic advertising approaches for services .....” Comment: What is “basic advertising approaches”? Need some clarity here. Would suggest to add some examples. XXXX, His Company

5C – a) Broad sets of applicability Month 20xx doc.: IEEE 802.21-02/xxxr0 5C – a) Broad sets of applicability Broad sets of applicability: “With the growth of WLAN technology, discovery  will become an increasingly larger issue in public ….”   Comment: Not clear what type of discovery is mentioned here? Need to be a bit more explicit describing the type of discovery. The PAR mentions only discovery of services. XXXX, His Company

5C – a) Broad Sets of applicability Month 20xx doc.: IEEE 802.21-02/xxxr0 5C – a) Broad Sets of applicability Broad sets of applicability: “A secure pre-association discovery mechanism of information related to accessible networks and services will increase the range of services and market reach of IEEE 802.11 devices.”  Comment: Again not clear what type of discovery is mentioned here? Need to be a bit more explicit describing discovery mechanism of what? For example, “discovery mechanism on information related to...” XXXX, His Company

5C – b) Multiple vendors and numerous users Month 20xx doc.: IEEE 802.21-02/xxxr0 5C – b) Multiple vendors and numerous users Multiple vendors and numerous users: “They perceive the need to standardize a secure pre-association discovery mechanism for IEEE 802.11 devices.”  Comment: Again not clear what type of discovery is mentioned here? Need to be a bit more explicit describing discovery mechanism of what? For example, “discovery mechanism on information related to...” XXXX, His Company

5C – Technical Feasibility Month 20xx doc.: IEEE 802.21-02/xxxr0 5C – Technical Feasibility B) Proven technology, reasonable testing: “All of the end components of the technology are in use today, although the pre-association discovery mechanism has not been developed yet. ”  Comment: Is the above statement correct? Is it not that pre-association network discovery mechanism exist today? May be it intended to say “pre-association service discovery mechanism has not been developed yet” XXXX, His Company
