what is the difference between dbm and dbi
Posted on 2002-06-29
does anybody gnow the difference between dbi and dbm. linksys insist on tellin me that the 2 antennas supplied with their wap11 are 15dbm, when everybody describe the output power in dbi. for example a corner reflectin antenna, is 9dbi and has a 75 degree beamwidth one way and 65 the other way.
gnow am i bein confused here deliberatly by linksys, cos they are very very stingy on technical details regardin the wap11. and i recall someone mentionin that the antennas wiv the wap11 are about 1.2 dbi each.
