WDS can be used to provide two modes of wireless AP-to-AP connectivity: 1  Wireless Bridging in which WDS APs communicate only with each other and don't allow wireless clients or Stations (STA) to access them. 2  Wireless Repeating in which APs communicate with each other and with wireless STAs.
WHEN the celebrated French painter Paul Delaroche saw the first Daguerreotype, the first primitive photograph at its unveiling in Paris on August 19, 1839, he announced to the assembled viewers: From today, painting is dead.
At first, like other pre-daguerreotype processes, Talbot's paper-based photography typically required hours-long exposures in the camera, but in 1840 he created the calotype process, which used the chemical development of a latent image to greatly reduce the exposure needed and compete with the daguerreotype.
