Link (telecommunications) - Uplink

  • Pertaining to satellite communications, an uplink (UL or U/L) is the portion of a communications link used for the transmission of signals from an Earth terminal to a satellite or to an airborne platform. An uplink is the inverse of a downlink. An uplink or downlink is distinguished from reverse link or forward link.
  • Pertaining to GSM and cellular networks, the radio uplink is the transmission path from the mobile station (cell phone) to a base station (cell site). Traffic and signalling flows within the BSS and NSS may also be identified as uplink and downlink.
  • Pertaining to computer networks, an uplink is a connection from data communications equipment toward the network core. This is also known as an upstream connection.
