Communications for coastal waters and offshore operations in the High North

Summing upRequirements from the different cases are identifying the same needse-Navigation requires highly developed communication meansNovel terrestrial technologies are well suited for coastal maritime communications, provided enhanced coverage and range is achievedLower (VHF/UHF) frequenciesMobile Multi-hop Relay and Mesh NetworkingNovel SatCom systems may be utilized to complement/supplement the terrestrial systems, e.g. to fill in coverage gaps and at deep seaObtaining seamless and continuous handover and roaming represents a primary challengeThe High North needs even more advanced and powerful solutionsHEO-satellites (Molniya and/or Tundra orbits)Crowded frequency spectrum represents a crucial limitationReclaiming UHF TV-bands within ”The spectral sirloin” region for maritime communications (700/800 MHz WiMAX)
