In telecommunications, pulse-address multiple access (PAMA) is a channel access method that enables the ability of a communication satellite to receive signals from several Earth terminals simultaneously and to amplify, translate, and relay the signals back to Earth, based on the addressing of each station by an assignment of a unique combination of time and frequency slots.
This ability may be restricted by allowing only some of the terminals access to the satellite at any given time.

Nothing is certain in life, but generally the chances of happiness are greater if one has multiple areas of interest and involvement. To juggle is to diminish the risk of depression, anxiety, and unhappiness.”

“Whilst the rights of all as persons are equal, in virtue of their access to reason, their rights in property are very unequal. One man owns his clothes, and another owns a country.”
