The satellite transmitter generates a signal that would jam its own receiver if both uplink and downlink shared the same frequency. The downlink frequency is one that is used for transmission of signals from the satellite to the earth station receiver. Internet downloads, for example, travel over a downlink to the downloading device, while internet uploads travel over uplink connections. In networks based on fixed lines the terms downstream and upstream are used to denote the data flow from the network to the end-user and from the end-user to the network respectively. A downlink is a connection made in the opposite direction of an uplink, either from a satellite to the ground or from an outside network into a local network. The router will not modify the packet addresses, except if it is doing NAT. The high bandwidth, a far cry from the grainy footage captured during the Apollo missions 50 years ago, could enable high-definition views of the moon in real time. It doesnt matter if there is a router (or even multiple routers) in between. If the destination address is your IP address, by your definition, it is a downlink packet. Therefore, the downloading of images and videos is done through the downlink process. If your IP address is the source address, by your definition, it is an uplink packet. What does downlink mean Information and translations of downlink in the most comprehensive dictionary definitions resource on the web. The downlink frame contains the information being sent to the users that are currently connected to the base station. Can the same frequency be used for uplink and downlink communication The uplink and downlink transmitters use separate frequency bands for transmissions therefore, both downlink and uplink transmitters can transmit at all times and at the same time 3. Edge terminals or nodes receive data from the network core or from higher-level network nodes such as routers and servers, and is commonly known as downloading. Definition of downlink in the dictionary. Uplink definition signal leaving your cellular device and going back to a cell tower. The term is used in the same way in computer networking. In satellite communications, downlink simply refers to the process when a satellite beams down information toward earthbound terminals or devices. It is a telecommunications link for signals coming to the earth from a satellite, spacecraft, or aircraft. The downlink is a term used in radio communications and satellite communications to denote the link from the network to the end user or from the satellite to the earth.
