  Communications
  This chapter discusses the networks (Section I), operations (Section II), radios,
  computers and base radio station (Section III), reports (Section V), electronic warfare
  (Section VI), antennas (Section VII) and operational environments (Section VIII),
  LRSU use to send and receive near real-time information. It also discusses
  communications in electronic warfare (Section IV) and unusual environments
  (Section VII).
  Section I. NETWORKS
  The LRSC must use several communications networks simultaneously. For example, the COB communicates
  internally, to the AOB, to higher, and to deployed teams. The AOB maintains nets to the deployed teams and
  the COB, and must be ready to communicate with the R&S squadron S-2, BFSB S-2, G-2, or J-2, if needed.
  The LRSC maintains an internal communications net with deployed teams. The deployed team must maintain a
  net to higher echelons and a team internal net.
  ARCHITECTURE AND FREQUENCY MANAGEMENT
  6-1. The LRSU have sophisticated and powerful communications equipment. They must also have
  access to multiple frequencies in multiple spectrums. Both are needed for the LRSU to send and receive
  near-real time information over many types of digital and analog systems.
  ARCHITECTURE MANAGEMENT
  6-2. The LRSU will need frequencies in the HF, VHF and UHF spectrums. Current communications
  systems operate in all three spectrums. The LRSU need multiple high frequencies for HF radio systems
  ever-changing optimum frequency of transmission (FOT) as well as multiple channel assignments for
  automatic link-establishment (ALE) radios.
  FREQUENCY MANAGEMENT
  6-3. Such complex communications require extensive frequency management. The BFSB S-6 is
  responsible for requesting frequencies with the JTF, corps or division G-6 to ensure that the unit is
  allocated a sufficient amount and type of frequencies to accomplish the mission The R&S squadron S-6
  and the LRSC signal platoon leader submit all frequency requests thru the BFSB S-6.
  OPERATIONS BASES
  6-4. Three primary networks and two backup networks are normally established for communications
  between operating bases:
  PRIMARY
  6-5. This includes--
  • Internal wire net with tactical switching system (landline telephone).
  • Tactical local area networks (LAN) for communication by computer or voice over internet
  protocol (VoIP) phones.
  • Combat net radios (single channel ground and Airborne radio system (SINCGARS)) and
  AN/PRC-148.
