Set of communication IP modules for field C2 posts
10
Backbone Connectivity Wireless Module

• This is the main communications module in the
  set.
• It provides monitoring and management of the
  whole deployed communications infrastructure.
• This module provides also all necessary
  interfaces to the other C2 networks and systems
  such as phone and LAN interfaces.
• The other goal of the module is establishing the
  backbone connectivity via channels of national
  network operators, local ISPs or connection via
  sattelite terminal.

Universal Communication Wireless Module

• This module is a power horse of the C2 post.
• It provides for the end users dedicated
  workplace with PC and standard set of interfaces
• phone services
• - video- and teleconferencing capabilities
• - mobile wireless connectivity
• - access to information resources via Web
  interface
• - print and fax services
• - e-mail services.

Access Point Wireless Module

• The module provides the base communication media
  for data exchange between all modules on the
  field.
• It is based on the IEEE 802.11 high-speed
  wireless standard and provides 11 Mbps (up to 54
  Mbps) connectivity.
• Using such a COTS standard it is also possible to
  provide connectivity in the serviced area for
  laptops and PDAs equipped with wireless adapters.

Video Wireless Module

• The module provides video surveillance
  capabilities and allows remotely to monitor
  different zones of interest.
• It is equipped with Hi-resolution network cameras
  with different capabilities which ensures
  day/night videomonitoring, monitoring of moving
  objects etc.
• Using network capabilities of the cameras it is
  possible to send real time video surveillance
  information across the all system and via
  Internet to the stationary centers too.

Conclusion

• The main criteria, beared in mind in process of
  building the JTSAC's communication
  infrastructure using COTS products, standardized
  and open communication protocols, open source
  software packages and theoretical modelling and
  simulation gives us a reason to believe that this
  approach is well suited and created communication
  infrastructure could successfully accomplish
  various tasks in the field of exercises,
  simulations and analyses.
