Dear 802.18 members,
cc 802.11 and 802.15 members,
On 14 September 2022, Portugal ANACOM began a public consultation on its spectrum strategic plan, which covers a wide range of topics including short range devices and license-exempt operations.
[1] Spectrum sharing techniques
Section 4.3 discusses different spectrum sharing techniques (both Wi-Fi and UWB are mentioned), and some example mechanisms including LBT and DFS.
ANACOM commented in its plan that it will continue to monitor the development of new spectrum sharing techniques, while taking into account the objective of maximizing the efficient use of spectrum. ANACOM aims to implement them on a case-by-case basis in Portugal, taking into account their suitability for the bands and services in question, demand and the national context with regard to spectrum usage conditions.
[2] Mobile services (upper 6 GHz)
Section 4.4 discusses the frequency bands ANACOM is interested in.
6425~7125 MHz is discussed in one of the paragraphs in this section. It recognizes that (1) it is one of the agenda items in WRC-23; (2) since November 2021, the CEPT is analyzing the possibility of making the upper part of the 6 GHz band available for Wi-Fi; and (3) there is a prospect or licensing of a fixed satellite service earth station (FSS) on Madeira Island to make or uplink data from the Rande and Integraty Monitoring Stations (RIMS) stations of the system. European Geostationary Navigation Overlay Service (EGNOS) for a Eutelsat satellite at 6725~7025 MHz.
66~71 GHz is also discussed in another paragraph in the same section. The band was also analyzed at CEPT and considered that the technical conditions reflected in Commission Implementing Decision (EU) 2019/1345 and in Recommendation ERC/REC 70-0327 already allow communications services next-generation (5G) wireless broadband electronics.
In this consultation, ANACOM proposed the following 5 strategic actions for mobile services:
a) Develop in a timely manner the appropriate regulatory framework for the implementation of mobile broadband, identifying additional spectrum for SCET (including for 5G/6G);
b) Encourage the use of wireless broadband technologies that allow the transmission data at higher speeds, as well as with lower latency and also ultra reliability, which allow the development of diversified scenarios;
c) Monitor and, if necessary, impose conditions to improve coverage and capacity of mobile networks throughout the national territory;
d) Develop frequency coordination actions at the international level as necessary, to avoid harmful interference;
e) Foster the growth and innovation of applications, namely M2M/IoT
[3] Intelligent Transport System (ITS)
Section 4.4.4 discusses the ITS and IEEE 802.11p is mentioned. It recognizes that, within the CEPT, compatibility studies are being carried out between ITS systems, which operate in the band 5875~5935 MHz, and between very low wireless LANs (WAS/RLAN VLP), operating at 5945~6425 MHz, in order to reassess the conditions associated with the operation of WAS/RLAN .
In this consultation, ANACOM proposed the following 2 strategic actions for ITS:
a) Monitor developments within the scope of the CEPT on the review of technical conditions for wireless LANs above 5935 MHz that safeguard application protection related to safety in the field of urban rail ITS below 5935 MHz, as well as safety-related applications in the field of road ITS below 5925 MHz (eg requirements in terms of out-of-band emission limits);
b) Encouraging the use of the 5875-5935 MHz band by intelligent transport systems urban rail and road transport, respecting the applicable technical requirements.
[4] Short range equipment
Section 4.12 discusses ANACOM's plan for the short range equipment and proposed the following 4 strategic actions:
a) Monitor developments in the SRD industry and prepare the framework in a timely manner regulatory framework so that new equipment, when placed on the market, can operate in Portugal, taking into account the growing importance of short-range equipment for the economy and rapid changes in technology and social needs. In this context, it should be noted that the CEPT is, since November 2021, analyzing the possibility of make the high part of the 6 GHz band available for Wi-Fi, although, as described above, the 6 GHz band (6425-7125 MHz) is also being disputed by the mobile community for terrestrial electronic communications services;
b) Monitor developments at CEPT regarding the Permanent Mandate of the Comissão Europeia: "Annual update of the technical annex of the Commission Decision on the harmonisation of radio spectrum for use by short-range devices"
c) Promote the harmonization of frequency bands exempt from licensing and their respective technical conditions for use by SRD at European and World level, in order to avoid harmful interference and ensure the greatest possible flexibility, promoting simultaneously a reliable and efficient use of the frequency bands by the equipment short-range, as well as the development of economies of scale;
d) Prospectively assess the impact that new spectrum needs for smart energy grids, smart meters, intelligent transport, M2M communications and IoT will have in the future, in order to ensure that the regulatory solutions to be implemented accommodate these developments properly..
