National Space Council officials to attend WRC-19 spectrum conference - SpaceNews.com
"Michael Beavin, senior policy adviser at the National Space Council, confirmed the council “is planning to send folks” next fall to the four-week conference, referred to as WRC-19, in Sharm el-Sheikh, Egypt."

"The satellite industry fared better than expected at the previous WRC in 2015, protecting the majority of the 800 MHz C-band from mobile operators wanting the spectrum for cellular networks. The satellite industry also flustered the U.S. Federal Communications Commission by uniting against U.S.-led efforts to examine satellite Ka-band spectrum’s potential for 5G cellular networks. . . . Francois Rancy, director of the ITU’s radiocommunication bureau, said last November that C- and Ka-band look like prime targets for cellular 5G ‘harmonization,’ or coordinating the spectrum on a regional or global basis for a single purpose."

"FCC Commissioner Michael O’Rielly echoed the importance of satellite communications, but said he remained frustrated with the satellite industry’s deflection on Ka-band at WRC-15."

Facebook ends ambitious Aquila program, will pursue partnerships instead | FierceWireless June 2018
"Facebook is getting out of the drone-building business, shuttering its facility in Bridgwater, U.K., and focusing on partnerships instead."

“Going forward, we'll continue to work with partners like Airbus on HAPS connectivity generally, and on the other technologies needed to make this system work, like flight control computers and high-density batteries,” said Yael Maguire, VP of connectivity at Facebook, in a blog post.

"Facebook said it will be working on a proposal for the 2019 World Radio Conference to get more spectrum for high altitude platform station (HAPS) systems"

Mobile and satellite industries disagree on potential 37–43.5 GHz 5G tuning range | PolicyTracker: the spectrum management newsletter
"These frequencies could all use the same equipment (unlike frequencies at 24.25–29.5 GHz) and they are all are on the WRC-19 agenda for potential identification for IMT in the Radio Regulations."

Summary of View A and View B submitted to IWG-2.

New generation of non-geostationary constellations poses challenges for WRC-19 | PolicyTracker: the spectrum management newsletter
"Article 22.2 of the Radio Regulations, the ITU document that manages international spectrum use, states that geostationary orbit (GSO) satellites cannot receive interference from NGSO satellites in fixed-satellite service (FSS) bands. However, the regulations do not yet include any rules on how this is to be achieved above 30 GHz.

To address this, agenda item 1.6 of WRC-19 considers the regulatory framework for NGSO satellites to use the fixed-satellite service at 37.5–39.5 GHz (space-to-Earth), 47.2–50.2 GHz (Earth-to-space) and 50.4–51.4 GHz (Earth-to-space).

In addition to preventing interference to GSO satellites, the rules also need to find a way for NGSO satellites to avoid interference to each other, to passive earth exploration satellite services at 36-37 GHz and 50.2-50.4 GHz and to radio astronomy services at 42.5-43.5 GHz, 48.94-49.04 GHz and 51.4-54.25 GHz."

"... WP 4A had identified a way to calculate unavailability: the convolution methodology. This is meant to protect GSO satellites without imposing onerous and spectrally inefficient equivalent power flux-density (EPFD) limits on NGSO systems.

It works by calculating the single entry increase in unavailability to a reference GSO link, compared to a maximum stipulated in the Radio Regulations. Administrations then determine the overall increase in link unavailability so that aggregate interference will not degrade the GSO satellites’ availability by more than 10 per cent."

US IWG-3: "Alexander Epshteyn, an engineer at Boeing, drafted a paper for the group’s meeting in late March that proposed solutions to protect GSO networks based on the convolution methodology."

ITU-R may move to milestone approach for satellite filing for NGSOs | PolicyTracker: Mar 2018
"A consensus is emerging during preparations for WRC-19 that a milestone process should be established for the bringing into use (BIU) of some of the larger non-geostationary orbit (NGSO) satellite constellations. This would oblige operators to demonstrate progress in building their constellations in order to obtain and keep their satellite filings."

"Hazem Moakkit, vice president for corporate and spectrum strategy at Intelsat, told a recent industry conference that at the moment you can have filings submitted for over 6,000 satellites, but the rules say you can BIU with only one satellite. “There is something broken here and it needs to be fixed,” he said."

"The milestones for NGSO satellites might start after seven years from the original application. After a few more years, an operator would have to show that they have a certain percentage of a constellation in operation. According to the current consensus described by Allison, there may be two more milestones, with the final one set 15 years after the first application. The longer timescale would reflect the greater complexity that these constellations would have in comparison to geostationary satellites."

Car industry not “waiting for 5G to happen” — PolicyTracker, May 2017
"Automotive companies are looking to ad hoc networks based on a vehicle-to-vehicle (V2V) approach, rather than vehicle-to-everything (V2X), a source at one automotive manufacturer told us.

We do not have a legal basis to say which technology should be introduced, even if we wanted to
Rather than “waiting for 5G to happen”, said the source, the industry will be looking at what it can do now, particularly with the IEEE 802.11p standard at 5.9 GHz (5875-5905 MHz), an adaptation of the standard used for Wi-Fi."

Privacy issue? "This will be done without a central network, as is envisaged in the V2X scenario. “Wherever there is someone, this device is implemented," the source said. "You’re telling the world constantly where you’re going and regardless of who's there, they can listen to it, similar to a phone-to-phone network.”"

"Europe's Radio Spectrum Policy Group (RSPG) said in February that “there is no evidence that spectrum availability is currently a constraint on the development of ITS, and there is no immediate need to take regulatory action in this regard.""

Spectrum for 5G, ITS and Wi-Fi likely to spark debate at WRC-19 — PolicyTracker, April 2017
"While it's still early in the process, the EU and US are beginning to firm up their positions on the agenda items for the 2019 World Radiocommunication Conference (WRC-19). Expect "tussles" over the need for additional spectrum for 5G, Wi-Fi and intelligent transport systems (ITS) as well as an increased focus on satellite services, says industry association techUK."
"One important feature of Agenda Item 1.13 (IMT allocations) is that it includes discussion of what the criteria should be for managing interference between new mobile services and incumbent services such as satellites, Raj Sivalingam, techUK's executive director for telecoms and spectrum, told PolicyTracker."

"WRC-19 will also take up several items relating to satellite services. Among these are Agenda Item 1.6 (studies of technical, operational issues and regulatory provisions for non-geostationary fixed-satellite services satellite systems in 37.5-39.5 GHz; 39.5-42.5 GHz; 47.2-502. GHz; and 50.4.-51.4 GHz); and Agenda Item 1.5 (use of the 17.7-19.7 GHz and 27.5-29.5 GHz bands by earth stations in motion communicating with geostationary space stations in the fixed-satellite service)."

UHF spectrum may be allocated for small satellites at WRC-19 - PolicyTracker Aug 2015
A proposal from the Netherlands says more spectrum is needed for the space operation service to accommodate the expected large growth in small satellite deployments. The proposal, submitted at a sub-meeting of the group developing Europe’s "common positions" for WRC-15, argues that the new allocation should be located between 137 MHz and 960 MHz

Does 5G require a new air interface? PolicyTracker May 2015
"Last month, some of the world's most eminent researchers met in New York to discuss the new air interface that may well come to define 5G technology. . . One of the researchers, associate professor of electrical and computer engineering at NYU Wireless Sundeep Rangan, told PolicyTracker that he expects 5G eventually to involve a new air interface that will work alongside many other technologies." - skepticism from Stephen Wilkus about power consumption in handsets to do antenna gain; from William Webb about beamsteering, and if capacity needed
