| 单词 | airwave transmission |
| 释义 | airwave transmission Synonymous with wireless transmission, as the term suggests open space rather than closed or confined space. Airwave is a bit of a misnomer, however, as the term also suggests transmission through the air, or atmosphere we breathe, which fortunately just happens to be there for us and the other living critters that share the Earths surface. Wireless transmission, however, definitely does not benefit from the atmosphere. Whether radio or optical in nature, wireless transmission suffers from any encounters with physical matter (e.g., atomic, molecular, and particulate matter) serving only to attenuate, impede, diffuse, distort, and otherwise interfere with the radio or optical signal. See also free space and transmission medium. |
