Wideband Networking Waveform (WNW)
����� Available on JTRS GMR and AMF-SA radios
mounted on vehicles and aircraft
����� Supports brigade and below lower Tactical Internet
backbone and local area networking, enables GIG
interface for mounted/dismounted network and
interconnects legacy and SRW subnets.
����� Provides mobile ad-hoc dynamic IP routing:
supports unicast, broadcast and multicast traffic.
Optimized for network routing performance, network
stability, and higher data throughput. Includes
functionality sufficient to organize, manage, and
dynamically control network connectivity structures,
routing mechanisms, bandwidth allocations and
spectrum restrictions. Supports concurrent
applications of multi level priority traffic via advanced
QoS implementation, including voice, data, and
video applications.
����� Network Throughput: 2 Mbps.
����� Provides no native voice capability, but supports
voice packet transport. Requires external voice
application.
����� Waveform operation between 225MHz and
2000MHz but hardware constraints utilize frequency
bands 225-400 MHz; 1350-1390 MHz; 1755-1850 MHz
(banded PA 225-960 MHz, 1350-1850MHz).
Soldier Radio Waveform (SRW)
����� Available on JTRS HMS, GMR and AMF-SA.
����� Supports local area networking for intra-unit
communications in the air and ground domains.
Optimized for CNR voice, dismounted/unmanned
applications, and small form factors with severe
SWaP constraints.
� � � � � Provides IP based inter-networking and Mobile
Ad-hoc Networking based Intra-networking
capabilities. Supports unicast, broadcast and
multicast traffic types. Network architecture assumes
stub net configurations. Provides special power
saving modes for IMS/UGS and Tele-ops mode for
UAV/UGV.
����� Network Throughput: 2 Mbps (with a single 1.2 MHz
channel, INC 1)
����� Provides native PTT based voice communications
through SRW CNR voice application. Single SRW
channel on a radio supports up to five logical voice
nets simultaneously.
����� Uses frequency bands 225-400 MHz; 1350-2500
MHz
����� Range: * 5 Km - SFF and Hand-Held form factors
����� Range:
* 10 Km: ground-to-ground
* 28 Km: ship-to-ship, ship-to-shore
* 370 Km: air-to-air, air-to-ground
����� Embedded GIG compliant HAIPE (1.3.5) COMSEC
suite. WNW network can be directly to the GIG.
����� Supports robust dynamic IP routing protocols
(OSPF, BGP) allowing the network to perform
backbone routing and increases network scalability
while interfacing with external networks (R-OSPF/ R-
PIM [SM-DM] implementation within waveform).
����� WNW Increment 1 modes of operation for the
signal in space / physical layer:
* OFDM – Bandwidth-efficient (2 bits/
Hz target)
* AJ – Anti-jam
����� Employs selectable channel bandwidths (1.2 MHz,
to 30 MHz) and variable data rates
����� Frequency reuse implemented through automatic
link adaptation (dynamic power and bandwidth
allocation) using Link Adaptation Algorithm and
Universal Slot Allocation Protocol.
����� Scale to 250-node subnet size, without precluding
scaling up to 1630 nodes.
* 10 Km - Manpack and GMR
����� AES based COMSEC/TRANSEC suite. Not fully
HAIPE 3.x compliant. Requires Red Gateways in
multi-channel JTRs to connect into the GIG.
(Typically via WNW)
����� Supports locally instantiated dynamic IP routing
protocol (RIPv2) to perform IP network route
discovery. Uses Link State based MANET routing
protocol within SRW networks. Not designed to
perform backbone routing.
����� SRW Increment 1 modes of operation:
*Combat Communications (CC) –
Bandwidth-efficient (1 bit/Hz)
*Electronic Warfare (EW) – Anti-jam (0.13
bits/Hz) with DSSS spread
� � � � � SRW supports selectable channel bandwidths
(75 KHz to 32 MHz)
����� Frequency re-use supported via spatial re-use
and frequency agility. Supports dynamic link
adaptation, contention based link access, as well as
allocated link access.
