4. 21-09-0046-00-00es 802.11 PAR and 5C Comments General comments: Emergency Services (E-911, PSAP, etc) are important services that may benefit from standardization. This needs to start soon, but we do not believe that 802.21 is not the proper place. We suggest that a separate 802 WG be considered to allow the autonomy and focus necessary to create a standard in a timely manner. This WG would also need to ensure cooperation and coexistence with the other 802 WGs. This is an EC decision/action. The PAR should be broken up into 3 separate destinct PARS 1-- Client to Authority (E-911) 2 – Authority to client (emergency warning broadcast – Amber alert) 3 – Authority to Authority (network prioritization and control) The PAR and 5C have been ammended to cover only the first category, Citizen to Authority or emergency call
