Framework ���� MOUT : current situation

Military Operations in Urban Terrain

� Complex situation due to urban environment : civilians, ambushes � need for awareness

� Command and Control are difficult

� Combats usually at squad level with low coordination with higher echelons

� Communication failures (indoors, urban canyons) with actual soldier radios

Dismounted soldier should not be isolated

Provide dismounted soldier with efficient communication system

4

Goals and roadmap ���� capabilities

Information processing & situation awareness

� Transmission of digitized information (maps, photo, videos, tracking and positioning data) that will permit to soldier squads to realize progression in an unknown environment,

� Exchange of shared situation awareness info between vehicular and soldier nodes.

� Connection with Command and Control.

Wireless secured & robust communication

� Based on MANET for connectivity

� Specific urban constraints :

� physical characteristics of the

building constructions,

� Specific propagation environment

� Possible jamming or limited availability of frequencies,

� Various countries, and situations, where frequency regulation may not be of concern

� Identified frequency bands

� V/UHF [200-400] MHz : propagation / crowded spectrum � Low data rate

� L band [1.3-1.7] GHz : short range / bandwidth � High data rate

� Propagation analysis provides models for

� Simulations of urban propagation

� Future tool for propagation prediction (range estimation)

� Proposal for a MAC layer

� Management for interoperability of the PHY modes

� Ensuring QoS continuity � TDMA, queuing mechanisms

� Adaptation to operational needs (Split & Merge)

� Clusterized network

� Cross-layer mechanisms (relaying, link status, QoS,…)

Technical insights ����MAC & PHY layers

16

� Candidates for PHY layer

� LDR waveform � max. range + LPI/LPD or AJ properties� Low data rate mode (in a 25kHz bandwidth for FH, 5MHz for DS),

� Medium data rate mode (in a 100kHz and 250kHz bandwidth for FH, 5MHz for DS)

� Emergency call mode (maximum robustness and elongation), but no MANET support.

� HDR waveform � high throughput

� FH into 1.25MHz or 5 MHz

� Multi carriers (OFDM/A, FFH-OFDM, MC-SS), single carriers (CPM) or SC-FDMA

� Candidates are being evaluated and selected through simulations (2010):� Robustness of LPI/LPD and AJ waveforms ?

� Performance and robustness to multipath of HDR waveforms (synchronization) ?
