When an uplink is being received by the spacecraft at the same time a downlink is being received by Earth, the communication is called two-way. Uplink and downlink communication are separated by guard times (period) to avoid overlaps. The communication going from a satellite to ground is called downlink, and when it is going from ground to a satellite it is called uplink. "The higher the data rates, the more information our instruments can send home to Earth, and the more science our lunar explorers can perform. Telecommunications, Aerospace a transmission path for data or other signals from a communications satellite or airborne platform to an earth station. Time Division Duplex or Duplexing (TDD) is a communication technique where uplink (phone to network) and downlink (network to phone) communications are sent on the same frequency band at different time slots.
Uplink definition signal leaving your cellular device and going back to a cell tower. The expectation might be users hosts will connect to the downlink ports and the uplink ports will take the aggregate traffic into the rest of the network. The uplink ports are gig and copper/fiber capable. In this particular usage, the switchs downlink ports are dual speed copper ports. Downlink definition signal coming from a cell tower to your cellular device. A downlink port generally mean the converse. "By infusing new laser communications technologies into the Artemis missions, we're empowering our astronauts with more access to data than ever before," said O2O Project Manager Steve Horowitz in a statement. Uplink and downlink, also called upload and download, refers to the two-way communication between a cell tower and your phone. The router will not modify the packet addresses, except if it is doing NAT. 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. The laser system will also be able to send and receive procedures, flight plans, voice messages and other communications between the Orion spacecraft and mission control on Earth. If your IP address is the source address, by your definition, it is an uplink packet. The downlink read-only property of the NetworkInformation interface returns the effective bandwidth estimate in megabits per second, rounded to the nearest multiple of 25 kilobits per seconds. HSDPA is also known as 3.5G and 3G+.It allows networks based on the Universal Mobile Telecommunications System (UMTS) to have higher data speeds and capacity. 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. High Speed Downlink Packet Access (HSDPA) is an enhanced 3G (third-generation) mobile communications protocol in the High-Speed Packet Access (HSPA) family. The O2O system will be capable of returning high-resolution images and video of the lunar surface back to Earth with a downlink rate of up to 260 megabits per second. Along for the historic journey to the moon will be the Orion Artemis II Optical Communications System, or O2O - making Artemis II the first crewed lunar flight to demonstrate laser communications technology.
