Telecommunications

  • Monitor radio emission spectral density, throughout the country
  • Measure mobile phone, radio and TV signal levels and quality throughout the country, to enable the cost effective and environmentally sensitive location of communications masts, to ensure adequate coverage, throughout the country.

  • Provide a temporary mobile phone and Internet LAN base-station-in-the-sky, for a remote site, or, a devastated region, where there is no coverage:
  • where an aircraft, train or a bus has crashed, where people may have wandered from the wreckage.
  • ship-to-shore communications
  • for an oil and gas exploration unit
  • a recurring theme is the loss of mobile phone coverage in a region that has suffered a natural disaster, such as massive flooding, or, a devastating earthquake.
  • Collect data from an array of Zigbee compliant sensors, located in a remote region.
  • Use Radio Direction Finding (RDF) technology, to locate sources of :
  • illegal radio transmissions, from the likes of pirate radio stations, commercial operators using unlicensed radio equipment, foreign agents and terrorists…
  • unintentional emissions, such as, electrically noisy motors, ignition systems
  • radio signals that might be interfering with cellular, radio, television or GPS navigation signals
  • emergency radio beacon signals, as might be used by a “downed” aircraft pilot, a lost explorer, or, by sailors from a ship that has sunk
  • use a pair of UAVs, to track a vehicle fitted with a radio beacon, using RDF.
