Network Centric Waveform (NCW)
����� Available on WIN-T MPM-1000 modems and
JC4ISR radios mounted on vehicles.
����� Provides OTM and ATH satellite communications
for range extension of the WIN-T backbone network
through the use of various MILSATCOM and
commercial transponded satellites.
����� Provides a full-mesh, multi-frequency, TDMA
network. Utilizes a network controller scheduler
that automatically calculates optimum connectivity
between all network terminals. Allows sharing
resources across the network and optimizes
throughput.
����� Burst Rate Throughput:
* ATH – up to 6 Mbps transmit and 12 Mbps
rcv.
* OTM – up to 1 Mbps
transmit and 3 Mbps rcv.
����� Uses frequency bands: SHF Bent Pipe SATCOM
operation. Uses Ka/Ku SATCOM bands On-the-
Move (OTM), and C/X/Ka/Ku SATCOM bands at the
High-band Networking Waveform (HNW)
����� Available on WIN-T HNR and JC4ISR radios
mounted on vehicles and aircraft.
����� Supports terrestrial and aerial LOS comms, both
OTM and ATH. Provides high capacity, long range,
full mesh networking WIN-T backbone
communications.
����� Provides mobile ad hoc networking by
automatically discovering and tracking moving
nodes. Operates with a narrow beam, fastswitching,
directional antenna for 360 degree plus
aerial coverage. Automatic in-band neighbor
discovery does not require operator intervention
to establish links.
����� Network Throughput: Ranges from 16 Mbps to
110 Mbps - dependant on modulation and FEC.
����� Uses frequency bands: C and Ku bands to
support ad-hoc ground-to-ground, ground-to-air,
74 Summer 2008
halt (ATH). FDMA backward compatibility to legacy
SATCOM terminals.
����� Range: BLOS Satellite
����� Includes TRANSEC protection for both user data
and waveform signaling. WIN-T provides external
COMSEC.
����� “Selectable” spread spectrum to support small
apertures & non spread for large apertures.
����� Supports peer to peer communications without
large hubs. Allows any advantaged node to act as
hub when needed.
����� Blockage mitigation techniques for OTM.
����� Supports a max of 31 subnets, and up to 255
members in each subnet
����� Full link management support: power control,
data rate control, adaptive coding and modulation,
and adaptive spectrum spreading. Dynamically
adjusts throughput based on link conditions.
����� Dependent on satellite payload and link conditions
air-to-air LOS communications.
����� Range:
* up to 45 km - ground-to-ground, pt-to-pt,
non-networking
* 44 km - ground-to air (ERMP)
����� Includes TRANSEC protection for user data and
signaling. WIN-T provides external COMSEC.
����� Provides spectrum efficiency of up to 2.2 bits/
Hz.
����� Frequency re-use implemented through
directional antenna networking (Directive Network
Technology – DNT) and auto-scheduled timeslots,
greatly multiplying frequency re-use (up to 15x).
Demand assigned timeslots allows sharing
resources across the network, reducing spectrum
required. Waveform dynamically adjusts
throughput based on link conditions.
