77th WG SE meeting - September 2017

The 77th meeting of ECC WG SE was held last 25-29 September in Sibiu, Romania, attended by about 57 participants, including the observer from the European Communications Office (ECO) and representatives of industry and/or operators: AB5 Consulting, APWPT e.V., ANITEC, ASP, Ericsson, EUROCONTROL, CAR 2 CAR Communication Consortium, Directorate General for Civil Aviation (France) , DJCSL, Intelsat, International Civil Aviation Organisation (ICAO),  Joint Stock Company Russian Space Systems, Ministry of Defence (France), NARFA Poland, Ring Advocacy, ROBERT BOSCH GmbH/European Telecommunications Standards Institute (ETSI), TeliaSonera and ViaSat, Inc.

The following documents were adopted on a preliminary basis and forwarded for the consultation phase:

  • Draft ECC Report 270 on “Sharing studies between Telecoil Replacement Systems (TRS) and Mobile Satellite Service (MSS) in the frequency range 1656.5-1660.5 MHz”;
  • Draft ECC Report 271 on “Compatibility issues related to NGSO satellite systems operating in the FSS bands 10.7-12.75 GHz (space-to-Earth) and 14-14.5 GHz (Earth-to-space)”;
  • Draft ECC Report 272 on “Earth stations in the frequency ranges 4-6 GHz, 12-18 GHz and 18-40 GHz in the vicinity of aircraft”.

The document ECC Report 267 on “Coexistence of Wideband Ultra-Low Power Wireless Medical Capsule Endoscopy Application operating in the frequency band 430 440 MHz” was approved for publication, after the public consultation phase.

Regarding work undertaken in project team 7 (PT SE7) - responsible for mobile service issues except international mobile telecommunications (IMT) - specifically the introduction of long term evolution (LTE) technology in the 450-470 MHz band for private mobile radio/public access mobile radio (PMR/PAMR) applications, the work continues. Nevertheless, given the number of studies received, the conclusions are still being discussed. A request from the ECC to analyse the introduction of low power wireless access network (LPWAN) networks based on SigFox technology was notably received.

In the same line, this project team is analysing the introduction of broadband public protection and disaster relief (BB-PPDR) networks based on LTE technology. Various studies have been presented. However, the preliminary conclusions indicate that the mitigation techniques (security distances) vary with the propagation model and guard bands considered.

A new task was also created at this meeting to analyse the use of applications for programme making and special events (PMSE), limited to 25 mW in the 960-1164 MHz frequency band.

Regarding project team 19 (PT SE19) - responsible for fixed service issues - it is analysing the introduction of fixed service applications in the 57-66 GHz band in outdoor environments (when existing regulations allow applications of the same kind, but with lower power and more restrictions when they operate indoors). The idea is to introduce an American technology (WiGig), described in ITU-R M.2227.

Regarding project team 24 (PT SE24) – responsible for matters concerning short range devices - the work concerning the task on wireless power transmission (WPT) will notably focus on vehicle chargers operating in the 70-90 kHz band. Two new tasks were also created:

  • smart tachographs to measure weight and size, operating in 5.8 GHz;
  • people detection and anti-collision, operating in 446-457.1 kHz.

Finally, a new project team 45 (PT SE45) was created – responsible for analysing the introduction of wireless local access networks (WLANs) operating in 5925-6425 MHz, given that studies for the introduction of such applications in the 5 GHz band have demonstrated that it is not possible.

The next meeting will be held on 22-26 January 2018 in Rome.
