Bob, Regarding the 802.15 NAN PAR, 802.16 agrees with the concerns expressed by 802.11. The coexistence issues raised by 802.11 are significant, particularly in consideration of other 802 standards deployed over large areas in the same spectrum. We have concerns regarding distinct identity, as well as the questions "Are there other
standards or projects with a similar scope?", particularly noting this description from the Scope: Specifically, the amendment supports all of the following: • Operation in any of the regionally available license exempt frequency bands, such as 700MHz to 1GHz, and the 2.4 GHz band. • Data rate of at least 40 kbits per second • Line of Sight (LOS) range of 5 km using omni directional antennae • Outdoor communications • PHY frame sizes up to a minimum of 1500 octets • Simultaneous operation for at least 3 co-located orthogonal networks • Connectivity to at least one thousand direct neighbors characteristic of dense urban deployment It appears that other 802 standards and/or projects, such, P802.16h, meet these conditions. This PAR proposes to amend a standard on Wireless Personal Area Networks by adding material to address a range of 5 km, keeping the term Wireless Personal Area Networks in the title. This seems to suggest an incompatibility. Roger Greetings and Salutations!! |
