WRC-19: summary of key decisions - PolicyTracker: spectrum management news, research and trainingPolicyTracker: spectrum management news, research and training
Agenda Item 1.13: mmWave bands for 5G. This was by far the most controversial and difficult item on this year’s agenda. Discussions, which have dragged on for months, concluded with three main outcomes:

The high-profile 26 GHz band received a global 5G identification through a groundbreaking time-delay mechanism. The idea is to help spur the development of 5G in the near term while protecting passive services in the long term once 5G networks become denser.
The whole range from 37 to 43.5 GHz has been globally identified for IMT, as well as 66-71 GHz
Two underrated frequency bands (45.5—47 GHz and 47.2—48.2 GHz) also received a 5G identification in some countries worldwide.

AI 1.6 looked at the coordination mechanisms for GSO (geosynchronous orbit) and non-GSO systems operating and/or planning to operate within the FSS (fixed satellite service) allocations in bands in the 37.5—51.4 GHz range, while 9.1.9 was seeking a new allocation for FSS. The main results were as follows:
AI 1.6 reached a compromise solution on the aggregate value of degradation of throughput as high as eight per cent.
New limits will ensure the protection of GSO networks while allowing non-GSO in Q/V bands.

WRC-19 introduced a milestone-based approach for the deployment of non-GSO satellite systems to guard against spectrum speculation.

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.

Airbus to establish Zephyr flight test centre in Western Australia | Jane's 360, June 2018
"Airbus has selected Wyndham Airport in Western Australia to be the primary flight test centre for its Zephyr ‘pseudo-satellite’ unmanned aerial vehicle (UAV)."

"The Zephyr is designed to operate for up to 45 days at a time at altitudes of up to 70,000 ft to remain clear of the weather and commercial air traffic. Potential payloads include an over-the-horizon communications relay for line-of-sight communications and/or a surveillance payload. The latest Zephyr-T (Twin-tail) being developed by Airbus DS increases the wingspan of the baseline aircraft from 25 m to 33 m, enabling it to carry as 20 kg payload."

BAE Systems reveals PHASA-35 solar-powered HALE UAV | Jane's 360
BAE Systems has revealed its PHASA-35 concept for a solar-powered high-altitude long-endurance (HALE) unmanned aerial vehicle (UAV) that can remain aloft for up to a year.

The Persistent High Altitude Solar Aircraft (PHASA) UAV features a 35 m wingspan, giving it the moniker PHASA-35. According to the company, a quarter-scale demonstrator known as PHASA-8 flew in 2017 and work is now already under way to prepare the first full-scale aircraft to be ready for flight tests in 2019.

The 150 kg PHASA-35 is being developed by BAE Systems in partnership with UK company Prismatic, which bills itself as an expert in the design, manufacture, and delivery of innovative, high-value aerospace products and systems.

Interference and Compatibility Studies Between Satellite Service Systems and Sys
Abstract
This paper provides the results of interference and compatibility studies in order to assess the sharing conditions between Fixed Satellite Service (FSS) and Fixed Service provided by High Altitude Platform Stations (HAPS) in the same operational frequency bands and discusses the most important operational parameters that have an impact on the interference calculations. To characterize interference phenomena between the two systems carrier to interference (C/I) ratios are evaluated. Simulation results under the scenario of a realistic deployment of HAPS and the use of different satellite configurations are presented. An interesting result derived from the simulations is that FSS/GSO Earth Stations and HAPS ground stations may coexist in the HAPS coverage area under certain considerations.

High-Altitude Platforms — Present Situation and Technology Trends, J. Aerosp. Technol. Manag. vol.8 no.3 , Jul/Sep 2016
ABSTRACT

High-altitude platforms (HAPs) are aircraft, usually unmanned airships or airplanes positioned above 20 km, in the stratosphere, in order to compose a telecommunications network or perform remote sensing. In the 1990 and 2000 decades, several projects were launched, but very few had continued. In 2014, 2 major Internet companies (Google and Facebook) announced investments in new HAP projects to provide Internet access in regions without communication infrastructure (terrestrial or satellite), bringing back attention to the development of HAP. This article aims to survey the history of HAPs, the current state-of-the-art (April 2016), technology trends and challenges. The main focus of this review will be on technologies directly related to the aerial platform, inserted in the aeronautical engineering field of knowledge, not detailing aspects of the telecommunications area.

Project Loon provides connectivity in Puerto Rico | PolicyTracker: Oct 2017
"The US Federal Communications Commission (FCC) has awarded Google a licence to operate its stratospheric helium balloons in Puerto Rico, but connectivity on the 4G system is limited to text messages and some internet access. "

" The original plan for Loon was to have a chain of balloons across the globe but the focus has now shifted to targeted deployments such as those seen in Puerto Rico, as this requires fewer balloons and allows Google to focus on areas not already served by terrestrial networks."

"UK mobile network operator BT/EE is working with a Texan company called Phazr on its own high-altitude platforms (HAPs) project, testing tethered balloons or “helikites”. Drones and outdoor use cases similar to the crisis coverage situations currently addressed by Project Loon are high on BT/EE’s agenda. . . . The trial used 26 GHz for downlink and 3.5 GHz and unlicensed spectrum in 5 GHz for uplink. "

Turning on Project Loon in Puerto Rico – The Team at X, Oct 2017
"Working with AT&T, Project Loon is now supporting basic communication and internet activities like sending text messages and accessing information online for some people with LTE enabled phones. This is the first time we have used our new machine learning powered algorithms to keep balloons clustered over Puerto Rico, so we’re still learning how best to do this. "

"Since our first sizable tests in New Zealand in 2013, Loon balloons have flown more than 26 million kms around the world. Thanks to improvements in balloon design and durability, many balloons stay airborne for more than 100 days, with our record breaking balloon staying aloft for 190 days."

Sharing and Compatibility Study between Fixed Service Using High Altitude Platform Stations (HAPS) and Other Services in the 31/28 GHz Bands | SpringerLink
Abstract
In the World Radiocommunication Conference 2000 (WRC-2000), use of the 31 GHzand 28 GHz bands was permitted for the fixed service (FS) by using highaltitude platform stations (HAPS) in some countries. This paper examines thesharing and compatibility of the HAPS-based FS with the other services usingthe same and adjacent frequency bands and establishes the conditions of thecoexistence with those services. Feasibility of dynamic channel assignment(DCA) scheme among the different communication systems to facilitate thecoexistence is also studied.

(19) INTERFERENCE ANALYSIS BETWEEN FIXED SATELLITE SERVICE SYSTEMS AND FIXED SERVICE USING HIGH ALTITUDE PLATFORM STATIONS IN THE V-BAND
Abstract
This paper provides the results of studies in order to assess the sharing conditions between Fixed Satellite Service (FSS) and High Altitude Platform Stations (HAPS) in the same operational frequency bands. To characterize interference phenomena between the two systems carrier to interference (C/I) ratios are evaluated. Simulation results under the scenario of a realistic deployment of HAPS and the use of different satellite configurations are presented. An interesting result derived from the simulations is that FSS/GSO Earth Stations and HAPS ground stations may coexist in the HAPS coverage area under certain considerations. arrive at a satisfactory long term environment. The efficient utilization of the same spectrum is of great importance due to the scarce resources of it. Taking into consideration the fact that the allocation of the fixed-satellite service in the bands 47.2-50.2 GHz for Earth-to-Space transmission is more important than that in the 37.5-39.5 GHz band in order to accommodate feeder links to broadcasting satellites and that the 47/48 GHz band is the unique allocation of HAPS fixed service in Europe, this paper investigates the requirements and criteria of the two systems in order to operate in the same frequency bands in an non-interference basis and discusses as well the most important operational parameters that have an impact on the interference calculations. At first the potential interference caused by HAPS platform directing to the geostationary satellite receiver is examined. To characterize interference phenomena between the two systems carrier to interference (C/I) ratios are evaluated and the interference values are compared with the maximum permissible interference powers for the proper operation of the Fixed Satellite System. The same procedure is followed for the examination of the interference paths from FSS earth stations to HAPS ground stations. The first section introduces a typical HAPS-based FS system in V-band while the second describes the operational technical characteristics of GSO/FSS systems plaaned for the 40/50 GHz band. The last section of this paper gives a detailed description of the potential interference between HAPS and FSS systems and summarizes the results of the interference analysis
