Most HF radio systems today use 3kHz (narrowband) channels, which limit the amount of data they can transmit. The latest (wideband) 4G HF waveforms offer 10 times the data rate of narrowband HF waveforms enabling greater use of HF radio in a modern data hungry world. Higher data rates also make HF radio easier to integrate into modern IP based communications networks, opening up HF to new communications services and enabling its use for more of the long range services currently carried over satellite communications.
Thales is unique in being able to offer two wideband solutions: the Mil-Std 188-110C/D 48kHz contiguous waveform and
the HF XL STANAG 4539 Appendix H 3kHz multi-channel non-contiguous waveform. Both offer similar maximum data rates, but HF XL uses up to 16 non-contiguous 3kHz channels over a 200kHz bandwidth rather than a block of contiguous channels covering a 24/48kHz bandwidth, making it much more likely that high data rates can practically be achieved. Whichever you choose, Thales has the answer to your wideband HF radio needs.
