Satellite Communication

 Why Satellite Communications?

  • In the majority of emergency situations, the terrestrial wireless infrastructure is either destroyed by the disaster which makes it critical for emergency workers to have access to a wireless communications network that is not dependant on terrestrial infrastructure.
  • Satellites are the only wireless communications infrastructure that is not susceptible to damage from disasters.
  • A group of satellites can cover virtually the Earth’s entire surface.
  • Since satellite solutions can be set up quickly, communications networks and new services can be quickly recov¬ered and reconfigured
  • Satellite technology can provide communications services such as Internet, data, video, or voice over IP.

 

Applications

  • Satellite technology can provide narrowband and broadband IP communications services such as Internet, data, video, or voice over IP.
  • Handheld terminals provides 64Kbps data rate. Bi-directional portable VSAT antennas provide 4 Mbps and fixed installation can bring the bandwidth up to 40 Mbps.

The Technology:

Equipments

1. Handheld Mobile Satellite Communications

  • These systems are provided by mobile satellite service providers.
  • They provide access through very small, cell-phone-sized devices, as well as pagers and in-vehicle units.
  • Prices for satellite phones can be as low as $40 a week for rental, with purchase prices ranging from under $400 up to about $2,000. Services are provided on a per-minute basis, as with any mobile telephone system, and start under a dollar a minute.

2. Portable and Transportable Mobile Communications

  • Mobile satellite systems, or terminals used for “communications on the move” include equipment that can be transported and operated from inside a car, truck or maritime vessel, as well as in helicopters and other aircraft, including commercial airplanes.
  • This kind of terminal is useful where data-intensive, high-speed connections are needed on an expedited basis for damage assessment, medical evaluation or other applications for voice, video and data.
  • Depending on the satellite system and type of equipment, they can be operational in anywhere from 5-30 minutes usually without expert technical staff, and can be deployed anywhere.
  • As with communications systems in general, higher satellite terminal prices – whether they are portable, mobile or fixed – equate to more robust services, higher reliability, faster delivery and a wide range of other features and options.

3. Fixed Satellite Communications

  • Fixed satellite communications terminals would typically be installed in cases where the equipment is required for longer than one week.
  • Such systems requires VSAT (Very Small Aperture Terminal) and it can be configured to provide everything from low-speed data transmissions up to very broad bandwidth data and full broadcast-quality video to replace local and national telecommunications infrastructure.
  • Such systems must be installed by a qualified technical team.
