COVID-19 hits the spectrum world - PolicyTracker, Mar 2020
"Huawei and China Telecom jointly set up a 5G-enabled remote diagnostic facility which enables doctors to conduct remote online consultations with potential patients, rather than risk face-to-face contact. Infections of healthcare staff in China and elsewhere has been a feature of the pandemic.

Chinese media has also reported the use of 5G-powered robots in the city of Guangzhou which remind people about frequent hand-washing and mandatory mask-wearing. Local media also said China Mobile has donated one robot each to two hospitals in Wuhan, the city first affected by the virus started. The robots carry disinfectant tanks and clean the hospitals along a predetermined route, reducing the risk of infection for staff.

In these scenarios, the virus is providing a use case for 5G and might conceivably spur faster deployment."

"T-Mobile USA was granted a 60-day special temporary authority to use additional spectrum in the 600 MHz band to meet increased customer demand during the outbreak."

"Interestingly, in Spain, whose citizens are in lockdown, the country’s fixed and mobile operators jointly implored users to moderate their bandwidth consumption, prioritising work and study and leaving streaming video and gaming until offpeak hours. The operators recommend voice calls should be switched to a landline, preserving capacity on mobile networks. IP networks are experiencing increases in traffic of close to 40 per cent, while mobile voice usage has rocketed by around 50 per cent and data by 25 per cent."

U.S. GAO - Potential Spectrum Interference Associated with Military Land Mobile Radios
"The new Land Mobile Radios operate in the same frequency range--380 Megahertz (MHz) to 399.9 MHz--as many unlicensed low-powered garage door openers, which have operated in this range for years. While DOD has been the authorized user of this spectrum range for several decades, their use of Land Mobile Radios between 380 MHz and 399.9 MHz is relatively new."

"Since DOD began its rollout of the new Land Mobile Radios in 2004, a number of complaints have been reported at several locations near military installations"

Simjacker – Next Generation Spying Over Mobile | Mobile Security News | AdaptiveMobile, Sep 2019
Via Amie Stepanovich

"... Simjacker. We believe this vulnerability has been exploited for at least the last 2 years by a highly sophisticated threat actor in multiple countries, primarily for the purposes of surveillance. Other than the impact on its victims, from our analysis, Simjacker and its associated exploits is a huge jump in complexity and sophistication compared to attacks previously seen over mobile core networks. It represents a considerable escalation in the skillset and abilities of attackers seeking to exploit mobile networks. "

"This S@T Browser software is not well known, is quite old, and its initial purpose was to enable services such as getting your account balance through the SIM card. Globally, its function has been mostly superseded by other technologies, and its specification has not been updated since 2009, however, like many legacy technologies it is still been used while remaining in the background."

Stakeholders not keen on EC’s reconfigurable radio systems proposal | PolicyTracker: Mar 2019
"A European Commission (EC) proposal to ensure that software uploaded onto radio equipment doesn't harm spectrum access, interoperability, safety or access to emergency services has drawn a mostly negative reaction from stakeholders who fear the rule could stifle innovation and competition. The EC said in its initial impact assessment that it is mulling a regulation on reconfigurable radio systems (RRS) under the EU Radio Equipment Directive (RED)."

"The EC laid out five options:

maintain the current situation in which device makers aren’t required to implement any specific measures (Option 0)
industry self-regulation to ensure that software doesn’t compromise initial compliance (Option 1)
adopt a regulation under Article 4 of the RED to require that manufacturers of radio equipment, or of software allowing radio equipment to be used as intended, inform member states and the EC about how the intended combination will comply before the software can be uploaded (Option 2)
adopt a regulation under Article 3(3)(i) of the RED to require that radio equipment support certain features in order to ensure that software can only be uploaded into it where the compliance of the combination of the equipment and software has been demonstrated for the purposes of market access (Option 3)
adopt a regulation requiring that both Options 2 and 3 be demonstrated before equipment is allowed on the market (Option 4).

"The 276 feedback messages received showed strong opposition to any option but doing nothing or allowing industry self-regulation."

Brussels urges EU member states to accelerate 5G spectrum assignments | PolicyTracker: spectrum news, research and training
"The head of DG Connect, which is part of the European Commission, has branded Europe’s current assignment of 5G spectrum “unacceptable” and urged countries to make more frequencies available. Roberto Viola used his keynote speech at this year’s European 5G conference to reiterate the Commission’s position on 5G and argue that member states need to move faster in assigning spectrum."

Viola quote: “The situation in the 700 MHz band is quite impressive; it’s equally impressive in the 3.5 GHz band, but it is devastating in the 26 GHz band. This is not acceptable.”

"The comments were made in the wake of the adoption of the European Electronic Communications Code, which turned 2020 targets into a legal obligation. All EU countries must now clear and assign 5G pioneer frequency bands (700 MHz, 3.5 GHz and 26 GHz) by the end of 2020."

"Moreover, Viola said he believed the “5G hype is justified” because it will become “the glue” which holds together all future technologies such as artificial intelligence, blockchain and advanced computing."

"Chinese manufacturer Huawei has again asked for patience and tolerance if initial 5G launches don’t live up to expectations."

UK and India offer contrasting spectrum trading experiences | PolicyTracker, Jan 2019
"A deal to swap spectrum between Telefonica and Vodafone in the UK received regulatory encouragement, while India's Reliance Jio Infocomm and RCom were given the cold shoulder. However, both situations indicate trading is on the rise. "

"The UK agreement is of interest because it is the first time two of the country’s mobile operators have agreed to trade spectrum without being told to by Ofcom as a condition attached to regulatory clearance of an M&A deal."

"Elsewhere, the US has always been a leader in swapping and selling spectrum, arguably treating it more like a financial asset than other mobile markets. In addition, because of the size of the market, licences are awarded on a regional basis, meaning operators often need to fill gaps in coverage, for which trading is suited. A similar argument holds in Australia."

CBRS spectrum sharing could be first good use case for blockchain | PolicyTracker, Jan 2019
The US Citizens Broadband Radio Service (CBRS) could be a "great candidate" for the first use of blockchain technology for spectrum sharing, according to Nokia's Seppo Yrjölä. Interest in the use of blockchain for spectrum management is growing, but problems such as regulation, costs and the lack of business models need to be sorted out.

Nextel Communications | Wiki | Everipedia
Nextel towers in the United States have caused radio interference with commercial and public safety trunked and conventional 800 MHz two-way radio systems. To resolve the problems, Nextel and the Federal Communications Commission developed a plan, approved by the FCC in August 2004, to relocate Nextel systems elsewhere in the 800 MHz band in order to reduce the potential for interference.

Ofcom sets 900 and 1800 MHz licence fees and consults on 3.4 and 3.6 GHz fees | PolicyTracker: Jan 2019
"UK mobile network operators (MNOs) will pay £1.09 million ($1.4 million) per MHz per year for 900 MHz spectrum, and £0.805 million ($1.02 million) per MHz annually for 1800 MHz spectrum beginning 31 January 2019, Ofcom said.

The levels reflect the full market value of the frequencies and take into account input from Vodafone, Telefónica (O2), EE and H3G (Three), as well as evidence from previous UK spectrum auctions and international benchmarks, the regulator added. The lump-sum values were converted into equivalent annual payments using an annualisation rate derived from a post-tax discount rate and a tax adjustment factor."

EXCLUSIVE: The spectrum bands carrying the most data, broken down by carrier | FierceWireless
"... in the charts and maps below, it’s clear that Verizon’s 700 MHz and AWS spectrum holdings are carrying the vast majority of the operator’s data traffic. But T-Mobile’s network is relying extensively on the operator’s 1900 MHz spectrum licenses—and the same goes for AT&T’s network. And Sprint, which is in the process of deploying additional 2.5 GHz services, already transmits much of its data across those licenses in urban areas, but not in rural areas."

Cybersecurity for Mobile Financial Services: A Growing Problem, CGAP Nov 2018
"... industrial-grade PIN harvesting is supplanting these slow approaches to obtaining individual PINs. There are many opportunities to acquire DFS account numbers and the associated PINs without ever meeting (or even knowing) the person whose money is being stolen. USSD is the most common form of access to mobile money services in developing countries, and it does not offer much protection for these sensitive credentials. Credentials can be collected in a number of ways that providers and policy makers should be aware of."

"CEPT is currently consulting on spectrum needs for the successor to GSM-R."

"The US regulator is considering a proposal from Metrom Rail for waiver of certain rules to allow the company to install and operate an ultra-wideband positive train control (PTC)system in the 3.272-5.015 GHz band."

"Freight and passenger railroads in the US are required by law to have PTC in place, including all the required spectrum, by 31 December 2018, with PTC systems fully implemented by the end of 2020."

Massive MIMO Will Create More Wireless Channels, But Also More Vulnerabilities - IEEE Spectrum, Nov 2018
"As wireless communications systems have to accommodate an ever-increasing number of data transfers, a lack of sufficient protocols for ensuring that data is transferred to the correct user could leave systems open to an attack."

"A major constraint of this approach, especially as the number of communication channels for each base station continues to grow, is the limited number of pilots available. Sometimes, users must be assigned the same pilot sequence, which can interfere with the proper transfer of data and lead to poor system performance. This is called pilot contamination. But this contamination can also be harnessed by an attacker to purposely interfere with data transfers. "

"when an attacker is close to the base station, within 300 meters or closer, he or she can impose their own pilots strongly enough to reduce the total transmission rate of a massive MIMO system by more than 50 percent"

"Pilot contamination can also be used to siphon off data transfers if the attacker’s pilot signals are strong enough, threatening the privacy of wireless communications. "

High-frequency traders flirt with high-frequency spectrum | PolicyTracker, Nov 2017
"The ongoing hunt for low latency communications between financial exchanges has generated renewed interest in the technology used for shortwave broadcasting – but using the spectrum in this way appears to breach of US regulations."

"Now an engineer in the US has stumbled upon the use of trans-Atlantic shortwave radio by high-frequency traders. As with the use of microwave, the rationale is that radio travels twice as fast through the air than light travels through fibre-optic cables."

"In addition to the technical limitations, the regulatory environment in the US, as it presently stands, also appears to cause problems for shortwave-based high-frequency traders: the Federal Communications Commission (FCC) does not appear to offer any sort of spectrum authorization product for this service."

"According to several commentators, most high-frequency traders overcome the regulatory vacuum by obtaining experimental licences. "

Physical layer security in wireless networks: a tutorial - IEEE Journals & Magazine
Wireless networking plays an extremely important role in civil and military applications. However, security of information transfer via wireless networks remains a challenging issue. It is critical to ensure that confidential data are accessible only to the intended users rather than intruders. Jamming and eavesdropping are two primary attacks at the physical layer of a wireless network. This article offers a tutorial on several prevalent methods to enhance security at the physical layer in wireless networks. We classify these methods based on their characteristic features into five categories, each of which is discussed in terms of two metrics. First, we compare their secret channel capacities, and then we show their computational complexities in exhaustive key search. Finally, we illustrate their security requirements via some examples with respect to these two metrics.

Thieves steal a Tesla Model S by hacking the entry fob - Engadget Oct 2018
"A Tesla owner who recorded thieves stealing his Model S by hacking the passive entry system has published the video on YouTube so we can all watch (and learn). It shows the crooks using a tablet to apparently capture the passive signal from his keyfob, then using the data to open the vehicle. "

"Tesla has recently implemented features to deter passive entry theft, but the owner sheepishly admitted he didn't use them. Namely, he failed to activate the "PIN to drive" feature that requires a further code before you can drive off. He also left passive entry -- which opens the car when you walk up to it with the fob -- enabled, even though it was parked outside. He also didn't use a "Faraday pouch" to store the fob, which would have prevented the thieves from nabbing the signals."

Radio Frequency-Activity Modeling and Pattern Recognition (RF-AMPR) | 2018
"OBJECTIVE: The PMW 120 Program Office desires a Radio Frequency Activity Modeling and Pattern Recognition (RF-AMPR) capability to perform pattern recognition, anomaly detection, and improved clustering of radio frequency (RF) signals. Specifically, it shall consist of a parametric RF classifier, a generative model of activity in the local electromagnetic environment, a machine learning-based anomaly detection method, and an RF data-clustering algorithm that classifies data that would otherwise be discarded by the parametric classifier."

"DESCRIPTION: Current automated RF data analysis and information discovery methods necessitate discarding significant volumes of sensor data as “non-analyzable”. This SBIR topic seeks to apply machine learning methodologies to better characterize this discarded data, enabling a more complete understanding of RF activity present in a specific environment."

"Anomaly classification shall include “known unknowns”, radio frequency events that are outliers of known classes, and “unknown unknowns”, anomalous RF events that represent new devices or activities."

Expert Commentary: The Dark Side of Detect and Avoid - Inside Unmanned Systems, Mar 2018
"Your task is to penetrate U.S. air surveillance networks, slip drones into American airspace and spy on critical infrastructure like dams, power plants, factories, etc. "

"EASY WAY NO. 1: Simply have 3PLA, the Third Department of the People’s Liberation Army’s General Staff Department—China’s equivalent to the U.S. NSA. hack into the databases of the NASA-designed future Unmanned Traffic Management (UTM) system to get fine-grained ground based DAA (GBDAA) data from the hundreds of radars that will be connected to UTM.... find out which companies are flying near your targets of interest, ... and then get 3PLA to hack into the target’s imagery servers. "

"EASY WAY NO. 2: This option is a bit more expensive, but gives you more control over the intelligence gathered. You do all the steps from easy way No. 1, but instead of just waiting, you take over their drone and gather your own imagery"

"EASY WAY NO. 3: Put your own data links on buildings near targets and take over drones to do your spying. A drawback to easy way No. 2 is that cell phone company cyber security is actually quite good, making it tough to hack into their network and fly them from China directly. Easy way No. 3 gets around cell phone company security by simply taking direct control of unwitting American drones. ... There’s a chance that upcoming airworthiness standards for beyond line of sight (BLOS) drone operations will err on the side of reliability and toss security out the window ... links that don’t ask too many questions when lost also don’t care if a slightly higher powered antenna takes over from their original ground station and gives their drone orders for a bit."

"EASY WAY NO. 4 (THIS SHOULD PROBABLY BE CALLED DEAD EASY WAY NO. 1): Start your own drone critical infrastructure inspection front company and make money while you spy!"

"The cell phone companies already have impressive cyber security for the relay portion of the network; your cell phone calls are very secure while they’re being relayed between cell towers. The problem remains with the drone data links themselves. The FAA simply must write drone command and communications standards that give link reliability and security equal footing."

"The issue will be the sheer volume of vetting required to manage the same level of security screening for the unmanned aviation business community."

Protect spectrum access systems from attacks, study says | PolicyTracker Sep 2018
"Keeping networks safe from malicious or inadvertent attacks isn't just a matter for the online world. As new technologies enable the development of more potentially interfering devices, instances of spectrum disruption are on the rise. The UK Spectrum Policy Forum (SPF) has 10 recommendations to help spectrum users, managers and installers fight back. "

"Disruptions may come from cyber-spectrum criminals seeking to make money from fraud or from industrial competitors and foreign intelligence agencies looking for an economic advantage for their companies or countries, the report said. Hacktivists might want to attack spectrum-dependent systems (SDSs) for political or ideological reasons, and company insiders with legitimate access to SDSs may cause disruptions accidentally or for malign reasons. Other SDSs in the same spectrum might disrupt though accidental or deliberate system configurations; changes to the local built or natural environment could also increase interference signals."

"Car theft is on the rise in the UK as more criminals use radio transmitters to perform “relay” car hacks.
"A robber in Saint Petersburg, Russia, defeated the alarm system in a jewellery store with a repetitive radio frequency generator whose manufacture was reportedly no more complicated than assembling a home microwave oven.
"GSM-R, which is part of the European Train Management System, involves some data which is safety-critical, said MacLeod. If the GSM-R connection is lost, the train must stop. Compact battery-powered jammers can be bought on the internet for GSM systems, and it’s likely they can be operated from within the train. In 2015, the number of interferences reported on GSM-R that could stop trains from running rose to the point where Finland reportedly switched to a domestic radio system.
"Other problems have included interference to meteorological radars from a 5 GHz disabled dynamic frequency selection mechanism and ground-based interference that caused the loss of meteorological satellite services."

"The draft version of the amendment bill–to be presented to the South African parliament this week–includes measures designed to encourage spectrum liberalisation, such as plans to create a national wholesale open access network (WOAN) and to enable spectrum sharing, trading and refarming as well as the introduction of a “use it or lose it” licensing regime.

"The new act also gives the government, instead of the regulator ICASA, full control of the national radio plan. However, the Ministry of Telecommunications and Postal Services must still consult with the regulatory body on future actions."

Drones and Frequencies to Fly on - ECC Newsletter August 2018
" CEPT held a Workshop on ‘spectrum for drones – UAS’ in sunny Copenhagen on 29-30 May 2018. The focus of the workshop was on drones which fly in circumstances where they do not need communications with air traffic control."

"The workshop heard from the European Aviation Safety Agency (EASA), which has new draft regulations before the EU Commission. The approach includes three categories of operations (Open, Specific and Certified) in an operation centric approach."

"These acts are expected to be published by the end of 2018 or in early 2019. They will be complemented by related standardisation initiatives."

"When it comes to UAS, frequencies are used in a number of ways: for command and control (CC) and identification, as well as for payload transmissions (e.g. on-board cameras sending information to the ground). Communications solutions are also needed for drones-to-drones, drones-to-infrastructure and for radar sensors and optical sensors on board the drones. In addition, they are needed for distribution of positioning information in order to avoid collisions, geo-awareness about fly zone restrictions such as around airports, sensitive facilities and locations, and drones traffic management."

"In the specific category, the basic principle is that a UAS operation, before being conducted, must be approved on the basis of a risk assessment."

"It was agreed at the workshop that, in the future, spectrum harmonisation may indeed be needed in areas of e-identification, geo-awareness and anti-collision. The various ideas for the technical solutions have, however, not converged in standardisation, while the use of several technologies may even provide a potentially safer approach using data fusion. Hence, the precise impact and needs for new frequency opportunities for drones/UAS is not yet clear."

"In February 2018, the ECC published ECC Report 268 on the technical and regulatory aspects and the needs for spectrum regulation when it comes to drones."

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."

A survey of the existence of GPS interference in Europe « Electronic Environment
"One of the objectives of STRIKE3 is the deployment and operation of an international GNSS interference monitoring network to capture the scale and dynamics of the problem, and to work with international GNSS partners to develop, negotiate, promote and implement standards for threat reporting and receiver testing."

"This article presents measurement results from a survey of the existence of GPS interference and jammers within Europe. The measurement started in the late March 2016 and ended in the beginning of July 2016. Interference detection equipment were deployed ‘as is’ in seven European countries; Sweden, UK, France, Czech Republic, Poland, Slovakia and Finland, see fig. 1. In total eleven different site locations are covered among these countries."

"there is a huge variation in the number of weekly events at each site, with some sites having only a few detections per week whereas others have several hundred ... The most active sites appear to be those next to major roads or in city center locations. These are also the busiest sites in terms of vehicles (which may carry jammers) and other sorts of activity"

", the greatest number of chirp type events (which are likely to be intentional and are associated with vehicle jammers) are seen at site 8 and site 10, with a significant number also seen at site 5. Those three sites are close to busy roads and hence that probably explains the high number of these types of events."

Intelsat's FCC Pipedream - Intelsat SA (NYSE:I) | Seeking Alpha, Paul Litchfield, June 2018
Via Rich Lee

"The Mobile NOW Act, passed in March of last year, instructed the FCC to make available at least 255MHz below the 6GHz frequency by the end of 2020, with a goal of making 500MHz available."

"You can see from these points that the satellite companies really do not have much to offer that is of value to the mobile companies or the FCC and thus their proposal is very unlikely to be accepted."

(p. 5)"SES investors have heeded their CEO's advice and built in only a very small premium for any potential FCC windfalls, in stark contrast to the gargantuan gains racked up by Intelsat."

(p. 5) "However, for the sake of argument, let’s assume that the satellite companies are somehow able to accomplish the herculean task of fixing all these six problems. They offer to vacate at least 300MHz of spectrum, they are able to trample the rights of the FS companies, they convince the FCC to act in a seemingly unfair, legally challengeable manner, they get all the other satellite companies on board and they manage to convince the mobile companies to pay for something that they don’t need (satellite service licenses) for time periods that are too short and for licenses that have already expired. In that case, how does this proposal look compared to the usual ways of vacating spectrum?"

Trump White House OSTP, others agree sharing will be key in future spectrum policy | FierceWireless Jun 2018
"With new and dynamic access techniques and technologies, sharing continues to offer a lot of promise, [Redl] said. "

"There are fewer opportunities for outright clearing and reallocation for exclusive use nowadays, and “I think that’s something that we’re going to have to pivot and really focus on how to make use of what we have and to move quickly to get to those goals,” she said. While there are still bands that can be cleared, that’s going to be both expensive and take a significant amount of time. Given the pace at which wireless is moving, sharing is going to be the way to achieve the goals and use the spectrum as soon as possible, [Guyselman] added."

Utilities come together to push for access to spectrum | PolicyTracker, June 2018
"Currently, there is no dedicated spectrum for use by utilities. Enterprises operate private LTE and digital mobile radio systems across various bands. While utilities have examined the potential of different bands, including 6 GHz, 3.5 GHz and 4.9 GHz, they have expressed a preference for 400 MHz because it has sufficient capacity and would provide favourable coverage for utilities to communicate over wide areas.

US utility companies are seeking to gain access to the 406-420 MHz band, which will have to be shared with federal government users and the National Telecommunications and Information Administration’s (NTIA) Interdepartmental Radio Advisory Committee. In continental Europe, utilities would use 450-470 MHz. The UK is currently considering 400 -450 MHz."

EU institutions reach agreement on Electronic Communications Code | PolicyTracker June 2018
"It adds that countries must allow the use of at least 1 GHz of the 26 GHz band, provided there is clear evidence of market demand and no significant constraints from existing users. The 32 GHz and the 40 GHz bands have also been identified as priority bands for 5G deployment.

The code says the EU welcomes increased cooperation among member states in spectrum management but underlines that spectrum usage varies across the Union and that flexibility for national governments must be preserved. For instance, the EECC proposes that the Body of European Regulators for Electronic Communications (BEREC) will issue standardised declarations for service providers, but national regulatory authorities (NRAs) will continue to have the lead role in general authorisations. "

“Peer review should contribute to a better exchange of best practices between Member States and increase transparency… but it should not be a formal condition of national authorisation procedures,” the draft document says. The peer review of national spectrum assignments will be led by the European Commission’s advisory body the Radio Spectrum Policy Group (RSPG), not BEREC.

"The decision to increase spectrum licences to 20 years, short of the 25 years the industry wanted, aims to secure return on investment."

Radio Spectrum Management; Ministry of Business, Innovation, and Employment

"A Managed Spectrum Park (MSP) has been established to allow access to a number of users in a common band of spectrum on a shared and, as far as possible, self-managed basis. The objective of MSPs is to encourage the efficient use of spectrum, innovation and flexibility, and to provide for low-cost compliance and administration. The 45 MHz allocated for the MSP is located at 2575 - 2620 MHz, although 5 MHz is required for a guard band at the lower boundary of the allocated frequency. The effective bandwidth available for services in the MSP is therefore 40 MHz, at 2580 - 2620 MHz."

Machine Learning for Performance Prediction in Mobile Cellular Networks - IEEE Computational Intelligence Magazine ( Volume: 13, Issue: 1, Feb. 2018 )
Janne Riihijarvi ; Petri Mahonen

In this paper, we discuss the application of machine learning techniques for performance prediction problems in wireless networks. These problems often involve using existing measurement data to predict network performance where direct measurements are not available. We explore the performance of existing machine learning algorithms for these problems and propose a simple taxonomy of main problem categories. As an example, we use an extensive real-world drive test data set to show that classical machine learning methods such as Gaussian process regression, exponential smoothing of time series, and random forests can yield excellent prediction results. Applying these methods to the management of wireless mobile networks has the potential to significantly reduce operational costs while simultaneously improving user experience. We also discuss key challenges for future work, especially with the focus on practical deployment of machine learning techniques for performance prediction in mobile wireless networks.

"Machine Learning and RF Spectrum Intelligence Gathering"

"Many applications that are central to RF spectrum intelligence gathering require some sort of pattern recognition. For example, to classify a signal by type we need to identify the particular pattern associated with the modulation, while to recognise that there is an interesting signal present in received data, we need to distinguish between pattern and noise.

In this White Paper, we explore how machine learning techniques can be applied to these applications of signal classification and anomaly detection to deliver faster and more effective performance to customers."

Who’s Afraid of a Pan-European Spectrum Policy? The EU and the Battles Over the UHF Broadcast Band | Ala-Fossi | International Journal of Communication Jan 2018

Several European Union (EU) member states have consistently opposed European Commission (EC) efforts to create a supranational EU spectrum policy, but only Finland voted against the EC at the World Radiocommunication Conference in 2015, proposing the release of the entire ultra-high frequency (UHF) band for mobile use. Originally, in 2007, the EC and Finland wanted quick release of the UHF for mobile, but the EC has changed its UHF policy completely. Based on a new institutionalism approach, this article argues that one of the main reasons for this development is that the EU’s spectrum policy planning system has become intergovernmental. The EU members are now able to force the EC to seek a wide consensus on spectrum policy. The unique Finnish spectrum policy stand is based on certain nation-specific institutional factors: concentration of power in the spectrum policy, strong economic orientation of the communication policy, and oversupply of UHF frequencies.

Wireless Technology Prospects and Policy Options | The National Academies Press
Via Paul Kolodzy

The use of radio-frequency communication--commonly referred to as wireless communication--is becoming more pervasive as well as more economically and socially important. Technological progress over many decades has enabled the deployment of several successive generations of cellular telephone technology, which is now used by many billions of people worldwide; the near-universal addition of wireless local area networking to personal computers; and a proliferation of actual and proposed uses of wireless communications. The flood of new technologies, applications, and markets has also opened up opportunities for examining and adjusting the policy framework that currently governs the management and use of the spectrum and the institutions involved in it, and models for allocating spectrum and charging for it have come under increasing scrutiny.

"There is an impasse between the Square Kilometre Array (SKA) SA and the local aviation industry over the restriction of some radio frequencies within the Karoo.

A draft Astronomy Geographic Advantage (AGA) Act has been published for public comment, seeking the protection of the SKA from radio interference. The frequency spectrum that is referred to in the AGA is from 100MHz to 25.5GHz."

"The Civil Aviation Authority (CAA) says a restriction on the frequencies would hamper two-way communication between pilots and the relevant air traffic control sector. However, the SKA says these draft regulations specifically recognise the importance of safety-of-life services, such as those used in the aviation sector, and provide for exemptions of these services from the strictest of the SKA protection requirements."

Radio frequency ban at SKA may see aircraft rerouted - BusinessDay Jun 2016
"A POSSIBLE ban of certain radio frequencies in the Karoo as a result of the Square Kilometre Array (SKA) project could see aircraft flying the Johannesburg-Cape Town route being redirected via Port Elizabeth, the Atlantic Ocean or over Upington."

"About 131,500ha of land surrounding the telescope’s 176-dish core, which lies 80km from Carnarvon, needs to be free from radio frequency interference. As a result, radio frequencies in the spectrum 100MHz to 25.5Ghz could be banned from a large portion of the Karoo. The ban would also have a negative effect on mandatory search, rescue and alerting services in the area. SA’s aviation authorities are opposed to a possible ban on the frequencies.
The Civil Aviation Authority (CAA) said a ban on the frequencies would hamper two-way communication between pilots and the relevant air traffic control sector."

"in 1942 patented the concept of “frequency hopping” that now underlies the spread spectrum radio systems used in products ranging from mobile phones to wireless networking systems ... It’s difficult, however, to draw a link from it to the PN used in CDMA cellular, GPS and early generations of Wi-Fi. It’s more likely that the roots of PN are Second World War cryptography and work by Paul Green at MIT Lincoln Lab"

Summary of a Forum on Spectrum Management Policy Reform | The National Academies Press
In 2003, the Department of Commerce’s Spectrum Policy Initiative was established with the objective of promoting a more efficient and beneficial use of the spectrum. As part of that Initiative, a series of public forums about spectrum management policy was held. The Computer Science and Telecommunications Board was asked to organize one of these forums, a public forum to gather the views of a variety of government and private sector stakeholders about the impact of spectrum policy on their activities. This report presents a summary of those views. Among those included are those representing national defense, homeland security, aviation, science, public safety, amateur radio, cellular voice and data, and terrestrial broadcast uses of the spectrum. Although prepared by the NRC, the report does not present NRC findings or recommendations. A broader study of spectrum policy, including findings and recommendations, will be issued in early 2005.

"Ludicrous and Ridiculous" – CEOs React to Intelsat's 5G Proposal - Via Satellite -
"Choi believes, first and foremost, that C-band or any other spectrum used in Geostationary Earth Orbits (GEO) does not belong to any satellite operator but rather by countries/administrations that are registered with the International Telecommunications Union (ITU). “The orbital slot filings operated by Intelsat belongs to an intergovernmental organization called the International Telecommunications Satellite Organization (ITSO) and I highly doubt they would agree to this preposterous move,” he said."

Choi believes there would be three violations of the rules and rights as defined by the ITU regulations at this move: “First, Intelsat does not own any C-band spectrum rights either in GEO or for use in terrestrial,” he said. “Second, the ITU Radio Regulations does not allow individual countries to assign satellite C-band spectrum for use terrestrially by any individual country. If the FCC agrees with this they would be setting a dangerous precedent and all other countries would follow suit. The radio regulations created in the ITU and its legitimacy maybe completely decimated, threatening the existing C-band operations in every country around the world. This would destabilize the fundamental business that even Intelsat has on a global basis. Third, C-band rights are assigned to multiple administrations that serve the United States and I don’t believe any other party would agree to go along with it.”

How Politics Stalls Wireless Innovation - WSJ, Oct 2017
Some of it is arguable, e.g.
• “LightSquared quickly spent about $4 billion” (it’s been a while since I dug around, but I couldn’t find any evidence in their bankruptcy filing that this much went out the door)
• “the FCC yanked LightSquared’s licenses” (it didn’t yank the license, it withdrew the ATC waiver that was conditional on not causing harmful interference).
• “To use radio spectrum, parties must stay in their lanes” (doesn’t seem to grok how overload works – or maybe he thinks parties have to assume infinite power in adjacent bands, and pay for reductions)

But there’s stuff to agree with, e.g. “the costliest spectrum conflicts emanate from overprotecting old services at the expense of the new.”

Interestingly, he says nothing about auctioning overlays (probably too hard to explain in an op-ed), preferring to ask for Ligado to get a pass, and sending border disputes to arbitration.

Intelsat, Intel Propose C-Band 5G Solution | Broadcasting & Cable
"Intelsat and Intel (no relation) are teaming up on a marketplace-based proposal to allow for joint use of parts of the C-band spectrum (3700-4200) for 5G wireless, with satellite operators giving up spectrum in metro markets for a price set by the marketplace. "

"They are proposing clearing some portions of the band for 5G use in "certain" major metro areas—certain regions would be easier to free up than others, clearing could include "transitioning their services and customers to another portion of the licensed C-band spectrum, physically moving ground antennas outside of the identified geographic area, or other means," they said. . . . So, instead of an FCC action, a consortium of satellite operators would make the spectrum available and it would go to whatever wireless operator found that spectrum "most interesting," said an Intelsat exec speaking on background—essentially a private instead of public auction."
