FUTURE USE OF MHZ AND MHZ

3. 1- Military usage of 870-876 & 915-921 MHz
Within around 12 CEPT countries
Remaining parts of a wider range ( MHz or part of it) mostly for Tactical Radio Relays
Already discussed in WGFM CivMil meeting
NJFA 2014’s update confirmed harmonized mil usage : TRR, unmanned systems telecommand, datalinks, …

FUTURE USE OF MHZ AND MHZ

4. SRD regime : general autorisation ECC REC 70.03 Soft harmonisation
SRD Challenges for Mil
SRD regime : general autorisation
Easy access to the market = a risk
ECC REC Soft harmonisation
national decision : Possiblity to ‘escape’ to the harmonisation but a risk with circulation of SRD equipment
EC Decision (Mandatory harmonisation)
contribution to the sharing studies
Last resort: negociation to maintain MIL usage (Art 1.4 – Spectrum Decision)
To monitor SRD demands to access to spectrum
ANTICIPATION ! CASE by CASE APPROACH !

FUTURE USE OF MHZ AND MHZ

5. 2a - Military usage in France
FR Mil usage: MHz & MHz
MHz shared with SRD
MHz & MHz shared with GSM-R
MIL Systems withdrawn from MHz
& MHz :
Safe harbour
Only usable « gap » between 470 and 1350 MHz
Trend : New MIL systems in & MHz

FUTURE USE OF MHZ AND MHZ

6. 2b - FRA national situation
No implementation of ERC REC for & MHz
Increased SRD demand to access to spectrum
Political decision to assess sharing with SRD
A national working group established in May 2015
Collection of data
Preliminary studies
Interviews with SRD industry
Refined studies
National position
=> Nov 2015
=> Feb 2016

2c - Studies – key points
Studies between June 2015 and May 2016
Conducted by the MoD with the support of the ANFR
6 types of representative military systems (in use) have been considered (robot/UAV telecommand, data links, etc.)
Use of Seamcat and WGSE scenarios
ECC Report 189 & 200 as an initial reference
Use of results of a national technical questionnaire to the industry
Challenge for Defense :
SRD parameters , SRD scenario (identIfied with support of ANFR)
To establish realistic simulation scenarios (military vs SRD)

FUTURE USE OF MHZ AND MHZ

8. 2c - EARLY RESULTS EXAMPLES
Very limited possibilities of sharing with for ex. generic SRD at 1% or 2.8 % DC at MHz
Possibilities with 0.1% DC
Insufficient margin
Better results at MHz with Wideband SRD or RFID

9. FUTURE USE OF 870-876 MHZ AND 915-921 MHZ
2c - FINAL RESULTS
Trilateral meetings with SRD industry
sharing and refined scenarios
2nd round of studies with slight improvements
Uncertainty maintained on density and mitigation techniques
Initial sharing scenario established and contribution from France in the CEPT process
Sharing opportunities identified with “red lines”
MHz DEF ONLY,
MHz sharing under conditions (generic SRD only in portion of the band)

FUTURE USE OF MHZ AND MHZ

10. 3- GENERAL CONCLUSIONS on sharing with unlicensed SRD
Dialogue between CIV /MIL
Knowledge of military applications (national usage only vs possible abroad missions)
Unlicensed spectrum implies a lack of control on the density of use : risk assessment
(key role of SRD scenario of deployments)
"non interference basis (NIB)“ Primary criteria
To ensure confidence to the incumbent
+ “non protection” = confidence in legal basis
The new entrant to accept/follow the sharing rules
