  * Higher headquarters’ execution timeline.
  * COMSEC key, period change, and compromise procedures.
  * Cybersecurity requirements.
  * Scheduled network outages.
  * Signal tasks—
   Specified.
   Implied.
   Essential.
  B-17. The G-6 (S-6) considers these facts and assumptions:
  * Maintenance status of communications equipment and systems.
  * Technical limitations of equipment—range, weather, and bandwidth.
  * Areas of limited communications coverage.
  * Higher headquarters support—
   Services.
   Bandwidth.
   Frequencies.
  * Personnel status.
  * Effects of the operational environment on communications.
  * Threat intelligence and EW capabilities.
  * COMSEC changes.
  * Command post locations.
  * Security of isolated or moving communications nodes.
  * Communications requirements of attached units.
  B-18. The G-6 (S-6) nominates commander’s critical information requirements and essential elements of
  friendly information related to signal support. During mission analysis, the G-6 (S-6) conducts signal site
  analysis (see paragraph A-51) to identify the most effective operating locations and updates the running
  estimate. The G-6 (S-6) begins collaboration with the G-3 (S-3), G-2 (S-2), and sustainment staff sections.
  This collaboration continues throughout the planning process. Table B-3 on page B-6 identifies the key
  inputs, planning process, and key outputs for step 2.
