Study Notes
- EHF (Extremely High Frequency) facilitates long-range satellite communication.
- It is characterized by a low probability of detection (LPD) alongside anti-jam features for naval vessels and land-based command centers.
- Due to its short wavelength, EHF signals exhibit vulnerability to disruption from rainfall.
- It supports both direct (point-to-point) and networked (netted) communication channels, accommodating voice and data transmission for Navy entities
- Secure voice/data communication includes:
Point-to-Point (PTP)
- Establishes voice or data circuits between a ship and another ship or shore-based unit.
NET
- Creates voice or data circuits connecting a ship with multiple ships or shore facilities.
LINK
- Supports MTJ (Multicast Transport Junction) services through a TIP (TDMA Interface Processor) path.
IP Services
- EHF serves as a redundant RF pathway for IP services, employing the EHF TIP circuit.
- TIP delivers secure IP networking capabilities to naval strike groups and individual ships lacking IP connectivity via alternative SATCOM systems.
