HFIA WorkshopWideband 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 !!

Number of 24-kHz channels available within 2-hours framesToulon [FRA] - 04/2013 - 10 dB over Minimum Noise Floor (±48kHz around each 150Hz sample)



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


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
