24 hours.
How long is each word-of-day (WOD) used with the HAVE QUICK II (HQII) communications multiple word-of-day (MWOD)?
|
Soldier radio.
Which type of advanced waveform enables data and imagery situational awareness and provides enhanced combat effectiveness?
|
d. Ultra-high frequency (UHF) network.
This is not a major network within the Military Auxiliary Radio Service (MARS).
a. Mission support network (MSN). b. Phone patch network (PPN). c. Very high frequency (VHF) network. d. Ultra-high frequency (UHF) network. |
Repeater.
Which type of conventional land mobile radio (LMR) device maximizes the communications distance between lower-powered equipment items?
|
Unbalanced channel loads.
Which statement is not a benefit of having a trunking network?
a. Selective radio inhibit. b. Faster system access. c. Unbalanced channel loads. d. Better channel efficiency. |
Link 11B.
Which tactical data link (TDL) is a secure, full-duplex, point-to-point digital data link that uses satellite, microwave, or terrestrial cable, as opposed to a modulated waveform, to transmit data?
|
the user programmed for his or her station.
In high-frequency (HF) communications, your station’s automatic link establishment (ALE) self-address is the address
|
decryption.
The process of unscrambling encrypted information so that it is intelligible is known as
|
duplexer.
In a land mobile radio (LMR) repeater system, a device that separates and isolates the incoming receive signal from the outgoing transmit signal and vice versa is known as a
|
Centralized core controller.
This differentiates the enterprise land mobile radio (ELMR) network from a regular trunking or conventional network.
|
Time division.
Which multiple channel access method eliminates the requirement for a net control station (NCS) in the joint tactical information distribution system (JTIDS) by providing node-less communications network architecture?
|
Individual.
This is the simplest form of an automatic link establishment (ALE) call.
|
Asymmetric.
Which type of cryptographic algorithm permits the encryption key to be public?
|
Single-site.
Which type of site configuration was designed to provide coverage for a small geographical area?
|
AFI 10–2501, Air Force Emergency Management Program.
Which Air Force instruction (AFI) requires communications squadrons to maintain installation notification and warning systems (INWS)?
|
Situation awareness data link (SADL).
The Air Force integrates with modified close air support aircraft with digitized battlefield information using this type of network.
|
Net.
Which automatic link establishment (ALE) call option lets you call a predefined group of stations with a single shared address, and requires them to respond, one at a time, in a predefined order?
|
KOI–18.
Which secure communications device operates by simply sliding the key tape into the reader?
|
Switching equipment.
This provides the interface between dispatch consoles and the central controller in a typical trunking system.
|
Control board.
In the giant-voice system, this controls the system’s signal routing and power distribution.
|
Wideband networking.
Which type of advanced waveform was designed to operate on manned, vehicular-based communication systems?
|
Andrews AFB, Maryland.
Where is the primary high frequency global communications system (HFGCS) network control station located?
|
over-the-air rekeying (OTAR).
The common name for the method of changing encryption keys over the radio channel in a two-way radio system is called
|
talkgroups.
When setting up a trunking network, users with common missions or functions are assigned as
|
Decoder.
Which is not a major component of the giant-voice system?
|
