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.
In 1842, Carl Stelzner made a daguerreotype photo of the Hamburg fire--the first spot news photo. But the wet-plate process was far superior for outdoor photography, and after 1851 we find the first extensive use of photography to chronicle events and scenery.
