signal strength near oceans

signal strength near oceans:-

Since cellular towers are on land, minimal coverage is there towards seas. Rivers, usually have lots and lots of trees near them. Trees are blobs of water hanging in air, because leaf's contain a lot of water. Water being extremely bipolar in nature absorbs EM energy, and we end up with poor/minimal signal there. Satellite signal is good on the sea level usually very good, because satellite signal does not suffer any multipath or interference as it would in common cities. In clear sky atmosphere you receive good satellite signal strength but it is still worse than you would have in any vast plain field on land. Reason again is heavy evaporation causes signal loss...
