WIN-T EXAM QUESTIONS & ANSWERS
Three Orbits for satellite - Answer -Geosynchronous, Polar, Low Earth Orbit
What is INC 1 - Answer -ATH only
What is INC 2 - Answer -OTM and ATH
What is a SAR - Answer -Satellite access request
What is a SAA - Answer -Satellite Access Authorization
What is uplink - Answer -Subscriber to satellite
What is downlink - Answer -Satellite to subscriber
What is a MODEM - Answer -Converts analog to digital baseband signals from a user
to an intermediate freq (IF) then to a low level radio freq (RF) thane through and
amplifier so it can be transmitted to satellite.
What are the MODEMs for INC 1 - Answer -TDMA and FDMA
What is TDMA - Answer -Time Division Multiple Access. Divides bandwidth into time
slots, 5 Mbps shared at BN and below
What is FDMA - Answer -Frequency Division Multiple Access. Has an upper and lower
limit that is divided into lanes so more subscribers can move through, dedicated 2.4-10
Mbps at BDE or higher
Where are gateways, Regional Hub Nodes (RHN) and Tactical Hub Nodes (THN)
found? - Answer -DIV and above
What are gateways - Answer -Physical buildings, gateways connect the tactical world
to the enterprise world, also called a STEP (strategic tactical entry point).
How many gateways are there - Answer -16
What bands does a gateway utilize - Answer -C, X, Ku/Ka & MILSTAR
What MODEM does a gateway provide - Answer -NIPR & SIPR
What is a Regional Hub Node (RHN) - Answer -Buildings that support up to 3 army
DIVs and are located beside gateways. Not every gateway has a RHN, there are 5 total
RHNs (Roberts, Bragg, Guam, Germany and Kuwait)
, What are the tiers and where are they found? - Answer -Tier 2 Routing - within the
army's network
Tier 0 Routing - at the gateway that goes to any platform
RHNs convert tier 2 to tier 1 to get to tier 0
What us a Tactical Hub Node (THN) - Answer -Trucks. Does the same as a RHN but
are mobilized units located at gateways that don't have RHNs. Found at DIV.
What bands does a THN use - Answer -X, Ku/Ka
What are the types of RHNs and what are their capabilities - Answer -Phoenix - Quad
Band (X, C, Ku, Ka). Has up to 2 antennas, 2=2 bands 1=1 band. Data rate is 52 Mbps
found at JTF.
SMART-T - MILSTAR Q-band. Data rate is 8.192 Mbps. Only SMART-T to SMART-t,
terminates at another. Found at BDE.
What is a Satellite Transportable Terminal (STT) and its capabilities - Answer -Towed
satellites. Use Ka/Ku bands, utilizes FDMA 2.4-10 Mbps and TDMA 5 Mbps shared
What is the Global Broadcast Service (GBS) and its Capabilities - Answer -Provides
worldwide seamless throughput. Data rate 23.5-45 Mbps. Provides video, data and
streaming. RECEIVE only does not transmit.
What is a VSAT (very small aperture terminal) - Answer -Increases the reach of the
local IP network traffic to distant stations. Tunnels classified and unclassified
information over the TDMA network.
What are the types of VSATs - Answer -SNAP (SIPR, NIPR, Access Point)
CSS VSAT (Combat Service Support VSAT)
What is a SNAP and its Capabilities - Answer -SIPR, NIPR Access Point. Provides
BLOS (beyond line of sight) voice, data, video and network capability. TDMA only.
Supports Ka/Ku bands. Used at company and below.
What are the 5 planning factors for a HCLOS - Answer -1. Grid Location
2. Azimuth
3. Frequency
4. Band (I or III)
5. Polarization (Vertical or horizontal)
What are the two types of Microwave LOS - Answer -BBU- Base Band Unit. Unit and
Power Supply
RFU- Radio Frequency Unit. Moveable, allows for band 1/3 freqs
What are the two types of HCLOSs - Answer --AN/TRC-190E (V1): One antenna LOS
shot at BN.
