Wideband HF spectrum availability
A quick practical approach
French MoD – DGA TN 11/FEB/2014 Slide #2 / 15
Introduction : first predicates
Information extracted from April 2013 sampling Band monitored : 2-30 MHz In the region of Toulon (France) Samples taken in 150 Hz increments during 2-
hours frames 2 hours for technical and stability reasons (better
representativity of statistical availability) Minimum and mean noise is computed +/- 48 kHz
around the central frequency except for 2.000 ≤ f < 2.048 MHz, and 29.952 < f ≤ 30.000 MHz
Channel considered « free » if no signal is detected 10-dB over mean/mini. noise level
Note: Data is available for the last 10 years !!

24-kHz channels availability (over mean/min.)
French MoD – DGA TN 11/FEB/2014 Slide #7 / 15
1st conclusions…
Mean noise floor around 48 kHz was retained over minimum noise floor for statistical representativity
3-kHz free channels represent 23.28 % of the whole band
6-kHz, 12-kHz and 24-kHz give respectively 17.18%, 11.05 % and 7.61 % availability
However : this is without considering LUF-MUF
French MoD – DGA TN 11/FEB/2014 Slide #8 / 15
2nd predicates… (1/2)
Considering LUF-MUF To be representative of real-time situations
2 scenarii : One « tactical » link (500 km) between Toulon and
Cagliari One « long way » link (2.700 km) between Toulon and
Suez Power output : 10 W (considering a 400W input
power dispatched over 16 3-kHz channels with a 2.5x backoff)
Computed using CNET (Télécom Bretagne) Point-à-Point software with 80 % reliability

Main conclusions…
Total number of 3 kHz-channels * hour: (30 MHz – 2 MHz) / 3 kHz * 24hours = 224.000
Channels available during 2 hours : 3-kHz : 4.358 100 % 6-kHz : 1.279 ( = 2.558 * 3-kHz) 58.7 % 12-kHz : 209 ( = 836 * 3-kHz) 19.2 % 24-kHz : 31 ( = 248 * 3-kHz) 5.7 %
3-kHz channels usability is very low 3.9 % availability amongst total (4.358*2hr/224000)
Fragmentation of the HF spectrum is of the essence : 2 solutions
Use non-contiguous 3-kHz channels Reduce HF spectrum fragmentation
