2% (or $1.3 trillion)* of World GDP is accounted for by the mobile telecommunications industry. By comparison, the minute fraction of this that the marine radar industry accounts for has probably not been discovered yet. So what chance does radar have against such overwhelming authority, or should we say, financial might? Marine radar operates in two main frequency bandwidths, 3GHz and 9GHz. The mobile phone and wi-fi industries also like the 3GHz arena, and have their frequency allocations virtually adjacent to our very own S-Band radar, and therein lies the problem.
