Space Internet Signal Standard BeaconLink Approved by ITU: Earth-Moon Communication Latency Drops to 1.3 Seconds
The International Telecommunication Union (ITU) today formally approved the BeaconLink space internet signal standard. The standard unifies communication protocols, frequency band allocations, and modulation schemes between Earth and the Moon, supporting interstellar link speeds of up to 10 Gbps.
BeaconLink uses the Ka band (26.5-40 GHz) as its primary communication frequency, with laser links serving as high-speed supplementary channels. The standard defines a dedicated transport control protocol, Space-TCP, optimized for the speed-of-light latency, reducing protocol overhead for Earth-Moon communication from traditional TCP's 40% to 8%.
Mark Choraz, Vice President of Satellite Internet at SpaceX, said: "BeaconLink provides unified communication infrastructure for future lunar bases, Mars outposts, and deep space probes. This is the first cornerstone of the space internet."
Both NASA's Artemis program and China's Chang'e project have confirmed adoption of the BeaconLink standard.
