these!
Why ESOMPs?
Broadband connectivity: anytime, anywhere
Why not typical MSS systems?
•
Typical Mobile-Satellite Service systems are not suitable for
modern applications:
•
Limited amount of spectrum (2x 41 MHz)
limited amount of
available throughput;
•
User Terminals are equipped with omni-directional antennas
no
spectrum sharing in the same geographical area;
•
No obligation to comply with specific eirp spectral density limits
sharing with other satellite networks is difficult.
What’s wrong with them

Which technical provisions should
ESOMPs comply with?

ESOMPs and FSS networks
•
space-to-Earth direction:
ESOMPs can operate with
typical FSS downlink pfd levels;
•
Earth-to-space direction:
ESOMPs shall:
•
Comply with the same off-axis eirp spectral density limits as those
contained in Recommendation ITU-R S.524-9;
•
Point and track the correct satellite
only
;
•
Take into account any unwanted and temporary mis-pointing and act
accordingly;
•
Be under the control of a Network Control and Monitoring Centre
(NCMC).
How ESOMPs will protect FSS
6
ESOMPs and FS networks
•
If coordinated,
typical FSS can share the spectrum with
FS,
therefore the same should apply to ESOMPs
SF-
series ITU-R Recommendations available;
•
Scenarios in which ESOMPs would have to share spectrum
resources with FS are:
•
Neighboring countries allowing terrestrial services in the same band;
•
ESOMPs operating in national/international waters/airspace.
•
What are the
solutions
?
•
Generic provisions (e.g. coordination threshold based on pfd);
•
Bi-lateral coordination and specific provisions.

Which regulatory framework for
ESOMPs?
8
ESOMPs and the RR
•
ESOMPs are not a new concept in the Radio
Regulations
;
•
No.
5.547A
allows for Earth Stations on Vessels to operate
in the C- and Ku-bands;
•
No.
5.504A
allows for AES to operate in the FSS in the Ku-
band;
•
Both approaches are subject to certain provisions to make
sure:
•
That existing and future FSS systems are protected;
•
That harmful interference is not caused to FS systems eligible to be
protected.
Learning from the past…
9
ESOMPs and the RR
•
Since WARC-92, No.
5.526
allows for networks which are both
in the FSS and MSS to include links between earth stations at
specified or unspecified points or while in motion;
•
Only recently a new class of e/s has been included in the BR
IFIC:
•
“
UC
”:
earth station while in motion associated with a space station in the
fixed-satellite service in the bands listed under provision No.
5.526
.
•
Administrations can now coordinate and notify ESOMPs that
communicate with the FSS based on existing criteria for FSS links
in the bands 19.7-20.2 GHz and 29.5-30 GHz, as appropriate;
•
ESOMPs are
not
operating under
4.4
in those bands covered by
provision No. 5.526.
A look to the present
10
ESOMPs and the RR
•
What else should be done?
•
Finalise the works of WP 4A on the
Draft New Recommendation on
ESOMPs;
•
Discussions on some limitations within
No.
5.526
are expected to take place in
the ITU.
Heading towards the future

To conclude…
12
The role of the Radio Regulations
•
They need to evolve, to allow a
flexible
and
efficient
use of
the spectrum resources;
•
Regulations should not be an
obstacle but encourage new
technologies to be promptly and
easily available.
Facilitating new technologies
