airFiber - What is HDD mode?


Hybrid Division Duplexing (HDD) is a special, proprietary wireless mode supported on AF24 which allows for half-duplex wireless operation, where same frequency is used on both TX/RX chains. This proprietary mode is similar to Time Division Duplexing (TDD) and allows for more resilient radio links, at longer distances.
