Everybody talking at once......avoiding that annoying superheterodyne squeal
Murphywasright addressed the problem of mutual interference if aircraft were to be broadcasting their data on the one V/UHF frequency. This has been resolved within "link" technology. i.e. no mutual interference. I imagine that it utilizes the same (or basically similar) handshaking protocols used to avoid interference/data collisions on the internet's pipes.
TADIL-A/
Link 11 is a secure half-duplex
TADIL radio link used by
NATO that receives or transmits--but not both simultaneously--a sequential data exchange digital link. It exchanges digital information among multiple airborne, land-based, and ship-board data systems. It is the primary means for exchange of complex changing data such as radar-tracking information beyond line of sight. TADIL-A can be used on either
high frequency (HF) or
ultrahigh frequency (UHF). However, the
U.S. Army uses only HF.
Link 11 will be replaced by
Link 22.
