Assumptions for AMI Application Ranging requirements March 2014 doc.: IEEE 802.11-14/0319r0 July 2014 Assumptions for AMI Application Ranging requirements Assumptions for AMI Applications: Endpoints do not move relative to Earth after installation. Ranging information is not needed immediately after installation Sub-1 meter range resolution not needed Victor (Silver Spring Networks) Jon Rosdahl, CSR
