A number of liaisons from several ITU-R Working Parties have been uploaded to the 802.18 Mentor website. The document numbers, titles and a very brief summary are given below.
18-17-0007-00, “Technical and operational characteristics and implementation of railway radiocommunication systems between train and trackside (RSTT) associated with work on WRC-19 agenda item 1.11”, Ongoing efforts of ITU-R WP5A regarding RSTT, also called Positive Train Control.
18-17-0008-01, “Technical and operational characteristics of digital land mobile radios for specific use”, ITU-R WP5A is developing a report on the technical and operational characteristics of digital private land mobile radios systems that provide capabilities (DPLMR).
18-17-0009-00, “Operational requirements and technical characteristics of systems in the land mobile service excluding IMT in the frequency band 51.4-52.4 GHz and adjacent or nearby bands”, ITU-R WP5A is requesting data as there are currently no ITU-R Recommendations or Reports that include such characteristics for the frequency ranges of interest.
18-17-0010-00, “Multiple Gigabit Wireless Systems”, ITU-R WP5A is requesting data in support of a revision of Recommendation ITU-R M.2003, which provides the general characteristics and radio interface standards for Multiple Gigabit Wireless Systems in frequencies around 60 GHz.
18-17-0011-00, “Request for Information on Machine Type Communications (MTC) in the land mobile service”, ITU-R WP5A is requesting this data in response to a request from ITU-R WP5D (IMT) for information on these type of systems.
18-17-0012-01, “Preliminary information on land mobile service applications associated with work on WRC-19 agenda item 1.15”, ITU-R WP 5A continues to developed a working document towards a preliminary draft new Report ITU-R M.[300GHZ_MS_CHAR] on technical and operational characteristics of the land mobile service applications operating in the frequency range 275 - 450 GHz.
18-17-0013-01, “Characteristics of terrestrial IMT systems for frequency sharing / interference analysis in the frequency range between 24.25 GHz and 86 GHz”, ITU-R WP5D (IMT) is requesting data on technology-related parameters related to technologies operating in that band.
18-17-0014-00, “Candidate frequency ranges and related information for Wireless Power Transmission (WPT) impact studies”, ITU-R WP 1A is tasked with liaising technical and operational information to WP 1B so that WP 1B may develop impact studies. (Note: That in a WP1A meeting in 2016 IEEE Japan proposed using 2450 MHz for WPT. Since it is a license exempt band they may have not listed it in this document.)
18-17-0015-00, “CHARACTERISTICS FOR USE OF VISIBLE LIGHT* FOR BROADBAND COMMUNICATIONS”, ITU-R WP 1A started development of a working document towards a preliminary draft new Report ITU-R SM.[VISIBLE-LIGHT] under Question ITU-R 238/1.
18-17-0016-00, “Preliminary information on fixed service applications associated with work on WRC-19 agenda item 1.15”,
ITU-R WP 5C continued to develop its working document towards a preliminary draft new Report ITU-R M.[300GHZ_FS_CHAR] on technical and operational characteristics and applications of the fixed service applications operating in the frequency range 275 450 GHz.
18-17-0018-00, “PRELIMINARY DRAFT REVISION OF REPORT ITU-R SM.2351-1 ON SMART GRID UTILITY MANAGEMENT SYSTEMS”, ITU-R WP1A has begun a revision of SM.2351-1, which was influenced by IEEE802, to incorporate 3GPP contributions.
All of these were presented in this morning’s meeting of 802.18. Others were informally discussed Monday evening.
