Performance
CSMA/CA performance is based largely upon the modulation technique used to transmit the data between nodes. Studies show that under ideal propagation conditions (simulations), Direct Sequence Spread Spectrum (DSSS) provides the highest throughput for all nodes on a network when used in conjunction with CSMA/CA and the IEEE 802.11 RTS/CTS exchange under light network load conditions. Frequency Hopping Spread Spectrum (FHSS) follows distantly behind DSSS with regard to throughput with a greater throughput once network load becomes substantially heavy. However, the throughput is generally the same under real world conditions due to radio propagation factors.

Famous quotes containing the word performance:
“The way to go to the circus, however, is with someone who has seen perhaps one theatrical performance before in his life and that in the High School hall.... The scales of sophistication are struck from your eyes and you see in the circus a gathering of men and women who are able to do things as a matter of course which you couldn’t do if your life depended on it.”
—Robert Benchley (1889–1945)
“So long as the source of our identity is external—vested in how others judge our performance at work, or how others judge our children’s performance, or how much money we make—we will find ourselves hopelessly flawed, forever short of the ideal.”
—Melinda M. Marshall (20th century)
“No performance is worth loss of geniality. ‘Tis a cruel price we pay for certain fancy goods called fine arts and philosophy.”
—Ralph Waldo Emerson (1803–1882)
