Comparison To Satellites
Since HAPs operate at much lower altitudes than satellites, it is possible to cover a small region much more effectively. Lower altitude also means much lower link budget (hence lower power consumption) and smaller round trip delay compared to satellites. Furthermore, deploying a satellite drains significant time and monetary resources, in terms of development and launch. HAPs, on the other hand, do not cost much and are rapidly deployable. Another major difference is that a satellite, once launched, does not allow for full maintenance, while HAPs do.

Famous quotes containing the words comparison and/or satellites:
“We teach boys to be such men as we are. We do not teach them to aspire to be all they can. We do not give them a training as if we believed in their noble nature. We scarce educate their bodies. We do not train the eye and the hand. We exercise their understandings to the apprehension and comparison of some facts, to a skill in numbers, in words; we aim to make accountants, attorneys, engineers; but not to make able, earnest, great- hearted men.”
—Ralph Waldo Emerson (1803–1882)
“To the Japanese, Portugal and Russia are neutral enemies, England and America are belligerent enemies, and Germany and her satellites are friendly enemies. They draw very fine distinctions.”
—Jerome Cady, U.S. screenwriter, and Lewis Milestone. Peter Voroshevski (Howard Clinton?)
