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.""

ITS Releases Key Software Model to Boost Collaborative Spectrum-Sharing Research | NTIA
The source code posted by ITS is a "reference implementation" of the Extended-Hata Urban Propagation Model (eHata), which was created to predict propagation of new commercial broadband services proposed to share the 3.5 GHz band with Navy radars. Those predictions enabled regulators to significantly expand commercial access to the 3.5 GHz band through the establishment of the Citizens Broadband Radio Service.

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)."

Fact Sheet: Administration Announces an Advanced Wireless Research Initiative, Building on President’s Legacy of Forward-Leaning Broadband Policy | whitehouse.gov
"NSF today is committing $50 million over the next 5 years, as part of a total $85 million investment by NSF and private-sector entities, to design and build four city-scale advanced wireless testing platforms, beginning in FY 2017. "
“DARPA is announcing its plans to demonstrate the viability of the technologies being developed for its latest Grand Challenge, the Spectrum Collaboration Challenge (SC2), within the testing platforms being announced today.”
"This fall, ITS will be sponsoring undergraduate and graduate student wireless spectrum research that will utilize the spectrum test bed that ITS is developing in collaboration with the University of Colorado-Boulder (CU-Boulder) to span the Federal and university campuses."

NTIA Technical Report TR-12-486 - Case Study: Investigation of Interference into 5 GHz Weather Radars from Unlicensed National Information Infrastructure Devices, Part 3 - ITS
In early 2009, the Federal Aviation Administration (FAA) became aware of interference to Terminal Doppler Weather Radars (TDWRs) that operate in the 5600–5650 MHz band and provide measurements of gust fronts, windshear, microbursts, and other weather hazards for improved safety of operations in and around airports. National Telecommunications and Information Administration (NTIA) engineers, with assistance from FAA engineers, determined the interference to be caused by some unlicensed national information infrastructure (U NII) dynamic frequency selection (DFS) devices operating in the same frequency band as TDWR systems. These devices use DFS technology that is supposed to detect the presence of nearby co-channel radars and change operating frequencies to prevent interference to those radars. This report, the third of a three-part series, describes some U NII emission spectra and introduces an additional set of TDWR test waveforms that the Federal Communications Commission (FCC) ...

NTIA Technical Report TR-11-473 Case Study: Investigation of Interference into 5 GHz Weather Radars from Unlicensed National Information Infrastructure Devices, Part 1 - ITS
John E. Carroll; Frank H. Sanders; Robert L. Sole; Geoffrey Sanders Abstract: In early 2009, the Federal Aviation Administration (FAA) became aware of interference to Terminal Doppler Weather Radars (TDWRs) that operate in the 5600– 5650 MHz band and provide quantitative measurements of gust fronts, windshear, microbursts, and other weather hazards for improved safety of operations in and around major airports. This report describes field measurements and results from an examination of interference to a TDWR in San Juan, Puerto Rico from unlicensed national information infrastructure (U–NII) dynamic frequency selection (DFS) devices operating in the same frequency band. Several U–NII devices from different manufacturers were found to be causing interference into the TDWR. These devices operate in the same bands as these Federal radar systems, but employ DFS technology that is supposed to detect the presence of nearby radar systems and change operating frequencies to prevent interferenc

NTIA Technical Report TR-15-517 = 3.5 GHz Exclusion Zone Analyses and Methodology
"This report describes the 3.5 GHz Study. It explains the assumptions, methods, analyses, and system characteristics used to generate the revised exclusion zones for small-cell commercial broadband systems to protect federal radar operations (ship and land based) from aggregate interference in the band 3550–3650 MHz. The 3.5 GHz Study’s exclusion zones are compared with the exclusion zones that were generated in the Fast Track Report, which considered macro-cell operations."

U.S. Department of Transportation Announces Decision to Move Forward with Vehicle-to-Vehicle Communication Technology for Light Vehicles | National Highway Traffic Safety Administration (NHTSA)
"The U.S. Department of Transportation's (DOT) National Highway Traffic Safety Administration (NHTSA) announced today that it will begin taking steps to enable vehicle-to-vehicle (V2V) communication technology for light vehicles. This technology would improve safety by allowing vehicles to "talk" to each other and ultimately avoid many crashes altogether by exchanging basic safety data, such as speed and position, ten times per second."

European C-ITS to take priority over Wi-Fi in 5.9 GHz band - PolicyTracker Feb 2014
"Brussels reassures industry that Wi-Fi in the 5.9 GHz band will not be allowed to interfere with C-ITS." "The focus for many of those at the 6th ETSI Workshop on Intelligent Transport Systems (ITS) is the development of standards for Cooperative Intelligent Transport Systems (C-ITS), which will enable vehicles made by different manufacturers to communicate with each other and with road infrastructure systems. The so-called "Release 1 specifications" for C-ITS have just been adopted and issued. A European Commission official assured delegates at the workshop that harmful interference from Wi-Fi in the 5.9 GHz band would be prevented. He said Brussels is committed to C-ITS, even if it means jettisoning plans to allow Wi-Fi to share C-ITS's 5.9 GHz band allocation."
