Reporting from the Nordic HF Conference – Wide Band HF
August 17, 2016
Isode CEO, Steve Kille, is attending, presenting at and reporting from the Nordic HF Conference (HF 16) on the island of Faro, Sweden.
WBHF is a key new development, and there were two good papers at Nordic HF on measurements during Session 2 on Monday.
Vivianne Jodalen, Terje Mikal Mjelde and William M. Batts reported on measurements made in the arctic (Wideband HF in the Arctic) and measurements made across the Atlantic (Performance of a transatlantic long-haul wideband HF system).
The good news is that a range of successful measurements were made in over-the-air environments. The practical results suggest that 6kHz channels (wider than 3 kHz narrowband) can often be achieved, but it was often not possible to realise the maximum of 24kHz. Throughput was generally quite a bit less than the “top end”.
While this is useful information and gives performance much better than narrow band, it is a long way short of the top end 120 kbps. I think there is a real risk that people have been over-sold WBHF and will be disappointed with the reality. This would be a pity, as it offers useful improvements.
