( KETRAUWAVE Xetadm—HP Emissions Designators Necessary Bandwidth Calculation (B,,) B,, is a calculation based on communication parameters set in the radio hardware. Both the FCC and IC define the same basic calculations in Part 2.202 and TRC—43.

Part 90.202 (c) (3) allows measurement where calculations do not covered by the documentation. The Xetawave modulation scheme combines a pulse preceding the packet data.
