2 November 2016 802.3 Comments Comment PAR, General— We suggest the scope be broader and reflected in the title. The term vehicular environment would be better than automotive environment. Need and Stakeholders talk about vehicles. We believe the project should address motor coaches and other non-automobile highway vehicles? The Need (5.5 highlights traffic jams as a potential problem, and therefore, a motor coach could be a coexistence challenge. The Scope need an appropriate terminology change. Response Accept. Changed “automotive” to “vehicular” Added the following to Section 8.1 “The term ‘vehicular’ in this context refers to vehicles that operate on roadways.” Steve Shellhammer, Qualcomm

3 November 2016 802.3 Comments Comment Further the note in 8.1 to 5.2 belongs in the scope. Response Reject. It is our understanding that Section 8.1 is the appropriate location for an explanation of terms like “vehicular environment” (originally “automotive environment”) Steve Shellhammer, Qualcomm

4 November 2016 802.3 Comments Comment PAR, 5.4 Purpose — Because Purpose is included in the standard, the statement should not include phrases like “typical scenarios the recommended practice will include:”. Could probably be rewritten “typical scenarios include:” Response Accept in principle. Used text provide by Steve Shellhammer, Qualcomm

5 November 2016 802.3 Comments Comment CSD — The CSD document uses both automotive environment and vehicle, and therefore causes the same concerns as expressed in the first general comment. Please use vehicular environment. Response Accept. Changed “automotive” to “vehicular” Steve Shellhammer, Qualcomm

6 November 2016 Comments Comment Change scope 5.2 to “This recommended practice recommends dynamic parameter values for IEEE 802 and Bluetooth devices operating in the 2.4 GHz band to enhance their performance in the automotive environment.” Response Accept in principle. Used this text except replaced “automotive” with “vehicular” Steve Shellhammer, Qualcomm

7 November 2016 Comments Comment 5.4 request to quantify “improvements in throughput, latency, reliability, PESQ (Perceptual Evaluation Speech Quality) score etc.” Response Reject. Since this is a Recommended Practice, the document cannot quantify the performance improvement. Steve Shellhammer, Qualcomm

8 802.11 Comments Comment 5.4 change “for example” to “such as”
November 2016 Comments Comment 5.4 change “for example” to “such as” 5.4 delete “the” prior to physical layer and medium access…(two instances) Response Accept Steve Shellhammer, Qualcomm

9 November 2016 Comments Comment 5.4 change “The typical scenarios the recommended practice will include: Interference among IEEE devices in the 2.4 GHz band. Interference between IEEE devices and non IEEE devices in the 2.4 GHz band. Non-IEEE devices in the 2.4 GHz band include but are not limited to Bluetooth devices.” To “The recommended practice addresses interference scenarios among and between 2.4 GHz IEEE 802 and non-IEEE 802 devices (e.g. Bluetooth).” Response Accept in Principle. Changed to “The recommended practice addresses interference scenarios among 2.4 GHz IEEE 802 devices. It also addresses interference between 2.4 GHz IEEE 802 and non-IEEE 802 devices (e.g. Bluetooth).” Steve Shellhammer, Qualcomm

10 802.11 Comments Comment 5.5 replace the Need for Project with
November 2016 Comments Comment 5.5 replace the Need for Project with “The automotive environment is one of the 2.4 GHz wireless environments with rapidly increasing deployment. This environment differs from the enterprise or residential environments. Automotive environments are characterized by high density of access points and stations (e.g. in traffic jams) with inter-AP distance of 2m-3m and dynamically changing interference conditions. There is extensive use of non IEEE 802 technologies in the 2.4 GHz band, which require consideration of coexistence issues. This recommended practice aims to improve coexistence and performance in 2.4 GHz. Response Accept in principle. Used this text except replaced “automotive” with “vehicular” Steve Shellhammer, Qualcomm
