Will Satellite Operators Become (Rural) Mobile Operators? - NSR, Feb 2019
"Connecting the “other 3 billion” is a recurring motto for the satcom Industry. Unfortunately, the reality is that the impact on mitigating the digital divide is still modest. Mobile is the de facto way of getting online for “the bottom of the pyramid” but here, satellite can still find enormous opportunities by complementing the gaps of terrestrial networks. Given this trend, are Wi-Fi hotspots over satellite the key way for satcom to bring the unconnected online?"

"Numerous actors in the satcom space are launching Wi-Fi hotspot offers to serve the low-end segments of the market. The addressable market for these kinds of solutions is massive given the billions living in underserved areas. According to NSR’s VSAT and Broadband Markets, 17th Edition report, Wi-Fi hotspot annual service revenues will reach $7.5 billion by 2027, representing 43% of total satellite consumer broadband revenues."

"With HTS becoming the norm, satellite broadband offers can now meet UN Broadband Commission affordability targets of 1 GB of data for less than 2% of the monthly GNI per capita"

"Today, a satellite terminal that supports double-digit Mbps with 10s of concurrent sessions combined with a Wi-Fi smallcell is below the $1,000 USD threshold, which is within the reach of local businesses."

"Selecting the right locations to set up the Wi-Fi hotspot is not trivial. It needs a reliable local microentrepreneur with appropriate technical skills to maintain the equipment and run the network. The village must be big enough with adequate disposable income to generate demand but not too large that it will shortly be targeted by terrestrial alternatives. In the same line, the hotspot should be far enough from terrestrial alternatives to avoid being cannibalized by terrestrial solutions, but penetration of mobile devices is crucial to ensure customers can access the network."

In-flight connectivity will be main driver of high-data-rate satellites, AnalysysMason Oct 2018
"Wi-Fi on board passenger aircraft will become the main driver of demand for next-generation high-data-rate satellites."

"We were asked to develop new regional market forecasts to 2025 for the following markets.
= Service provider trunking. Traditional point-to-point connectivity for telecoms service providers and mobile backhaul.
= High-bandwidth enterprise services. Both land-based and offshore services.
= Mobility platforms. In-flight connectivity (IFC) for passenger aircraft; connectivity for cruise ships, ferries and other large vessels; passenger connectivity on railway trains."

"We forecast that the worldwide market for high-speed satellite trunking services will grow in value from EUR1.9 billion in 2017 to EUR4.7 billion in 2025. We believe that the fastest-growing segment will be in-flight connectivity for passenger aircraft, where wholesale revenue will grow from EUR278 million in 2017 to EUR1.9 billion in 2025."

Leading RF Security Vulnerabilities in 2018 — Bastille
Wi-FI: Krack
Keyless entry
Medical devices
Remotely hijacking vehicles

"RF vulnerabilities are most often not the result of flaws in operating systems and applications. The problems often reside in the firmware of communications chips, which are trade secrets not open to public inspection. An attack on them bypasses not just network firewalls but many forms of detection. The vulnerable devices are often simple, mass-produced ones, the kind found on the Internet of Things. Many manufacturers pay more attention to price than security."

LTE and Bluetooth in-device coexistence with WLAN
Modern mobile phones can support cellular and non-cellular wireless communications standards at the same time. This means, however, that the subsystems must operate in very close proximity to each other within a single device (in-device coexistence). The resulting high level of reciprocal leakage can at time cause considerable interference.

The role of unwanted emissions and receiver performance in spectrum management - ECC Newsletter May 2018
"When the '800 MHz' band — from 790-862 MHz — was studied for mobile (4G) usage, compatibility studies (see CEPT Report 30) showed that both unwanted emissions from mobile systems and selectivity of the digital terrestrial television (DTT) receiver could have an impact on DTT reception. However, the studies also found that reducing further unwanted emissions of 4G base stations beyond a certain level would not provide additional mitigation because receiver selectivity would then be the dominant interference effect."

"The boundary between the out-of-band and spurious emission domains is usually defined as 2.5 times the transmitter’s bandwidth, but there are some exceptions to this rule. "

"Particular challenges in this ongoing review are raised for 5G technology using active antenna systems (AAS). In this case, the antenna array is integrated in the device, which means that unwanted emissions cannot be as easily measured. It has also been reported that it will be difficult for 5G systems in millimetre wave bands (26 GHz and above) to meet the existing limits, due to constraints on filtering technology."

"In ECC Report 249, published in 2016, measurements of a range of different types of transmitters showed that typical equipment generally exceeds – by some margin— the minimum requirements for both out-of-band and spurious emissions. Therefore, assessing interference based on the minimum requirement represents a worst-case scenario which may limit opportunities for sharing. The report concluded that sharing and compatibility studies should reflect actual equipment performance in order to ensure efficient use of spectrum. Ideally a statistical distribution of unwanted emissions should be used in the studies to capture the spread in performance of different equipment models."

ViaSat, Intelsat, OneWeb cite access to spectrum as big concern | FierceWireless Oct 2017
"Asked about the major factors affecting investment in next-generation satellite technology, several leading satellite players said access to spectrum is the No. 1 issue. Executives from ViaSat, Intelsat and OneWeb testified Wednesday during a U.S. Senate Committee on Commerce, Science and Transportation hearing"

"Another related area: unlicensed spectrum. The business model changes dramatically when unlicensed spectrum is made available. In Africa, ViaSat needs to go through cellular operators to provide service, but the cell equipment costs thousands of dollars. In Mexico, it’s able to go directly with its own satellites and put in a Wi-Fi hotspot for $1,000, so seeing regulations to support those kinds of models would be very helpful, Dankberg said."

"As more satellites are launched, the potential for collisions rises, and OneWeb’s Wyler stressed that a more formal process needs to be created to prevent catastrophe in space."

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)."

UK regulator to allow Wi-Fi at 5.8 GHz before rest of EU — PolicyTracker: the spectrum management newsletter
Interference concerns came from users of the fixed satellite service; radar; programme making and special events equipment; broadband fixed wireless access; amateur radio and satellite; and short-range devices (SRDs), including drones. "We examined these coexistence arguments... and have not found a compelling reason not to authorise 5.8 GHz for Wi-Fi services given the benefits this extension will deliver for citizen[s] and consumers," Ofcom said. It set a proposed power limitation at 200 mW equivalent isotropically radiated power (EIRP) per channel, with no fixed outdoor use, and with a requirement to implement specific techniques to avoid interference into radar.

Improving spectrum access for consumers in the 5 GHz band - Ofcom
From cover email:
"Ofcom has today confirmed plans to increase the amount of spectrum available for Wi-Fi in the 5 GHz band. In the future, this could enable better wireless broadband for consumers.
As broadband delivered to the home gets faster, people increasingly expect their Wi-Fi to provide several services at once – such as video streaming, video calls, gaming and remote working. This demand puts pressure on the spectrum which carries Wi-Fi signals.
Many Wi-Fi routers in the UK currently use a part of the spectrum called the 2.4 GHz band, which is becoming increasingly congested and can impair broadband performance. Many people have newer broadband routers, which use not only the 2.4 GHz band, but also the 5 GHz band – which has much more spectrum and is less congested.
Ofcom has decided to open up an additional ‘sub-band’ within the 5.8 GHz section of the 5 GHz band. In deciding to do so, we have taken into account the impact on other existing users, such as satellite services.
The extra sub-band will result in 125 MHz more spectrum. This will allow for two more 80MHz channels to accommodate data-hungry applications. These extra channels are already being used in other countries, including the US.
In order to implement the decision, Ofcom is now consulting with UK stakeholders on proposed regulations which will allow Wi-Fi use in this band. The making of the new regulations will also be contingent on any comments the European Commission may have on the technical parameters we propose to apply to the use of the band.
The closing date for responses to this consultation document is 11th April 2017."

Globalstar shelves controversial proposal for unlicensed spectrum, asks FCC to OK revised plan | FierceWireless Nov 2016
After years of being in limbo, Globalstar says it’s backing off a proposal to launch a wireless network that critics said would have interfered with Bluetooth and Wi-Fi devices. Instead, the company told the FCC that it wants to “narrow the relief” it originally sought and urged the commission to adopt rules that will expedite the outcome of a Notice of Proposed Rulemaking (NPRM).

The move, reported by Network World last week, represents a big change in Globalstar’s plans.

LTE vs. Wi-Fi Simulations: The output is only as good as the input | Joey Padden | Pulse | LinkedIn
The punchline seems to be

I understand and appreciate the engineering desire to strictly adhere to the spectrum management principle that the government should not regulate unlicensed spectrum uses. Focused narrowly on spectrum management doctrine, unlicensed is supposed to be the home of permission-less innovation. But in my mind LAA/LTE-U pose a broader public policy question. Stated simply it is:

“Should private wireless carriers that want to save money by moving data traffic from expensive licensed spectrum to free unlicensed spectrum be allowed to interfere with public Wi-Fi used by millions of consumers and by important institutions and infrastructure in our society?”

To me, the broad public interest answer to this question is self-evident - “no”.

Another criticism is limited scope:

There are two primary issues with this analysis, firstly the papers present this work as covering “a large design parameter space” when in fact these simulations cover a narrower parameter space than that used in the 3GPP simulation efforts. Areas not studied in this analysis include: <long list of stuff>

He goes on to critique various other aspects, including “These simulations assume throughput as the only metric. But, latency is a first order performance metric.”

Mobile operators to shift from "pure Wi-Fi" to unlicensed services tied to LTE, says report — PolicyTracker: Jul 2016
"At least 90 per cent of mobile data will be carried over unlicensed bands anchored to variants of LTE by 2020, according to a report from research firm Mobile Experts. But it's still not clear whether there's any real need to aggregate unlicensed with licensed spectrum.
The report, "Carrier Wi-Fi and LTE-U 2016," predicts a "decisive transition" from "pure Wi-Fi" to the tying of unlicensed services to LTE in various ways."
"Around 80 per cent of mobile data is carried over Wi-Fi today, but that figure will rise to at least 90 per cent by 2020, said Mobile Experts analyst Joe Madden."
"What's really needed is "close cooperation between 3GPP, IEEE and regulators to develop a consensus on rules for hybrid band sharing and aggregation (fixed/mobile converged networks that combine licensed and licence exempt band use)," said Horvitz. And if not rules, he added, then there should at least be principles concerning technical and coexistence fairness issue"

AT&T, Verizon, T-Mobile throw support behind new LTE-U, LAA coalition - FierceWirelessTech
"Some wireless rivals that often don't see eye to eye on wireless policy issues are banding together behind Evolve, a new coalition launched in Washington, D.C., today to promote the benefits of unlicensed spectrum and new technologies like LTE-Unlicensed (LTE-U) and License Assisted Access (LAA). AT&T (NYSE: T), Verizon (NYSE: VZ) and T-Mobile US (NYSE:TMUS) are among the participants in a group, which also includes CTIA, the Competitive Carriers Association (CCA), Alcatel-Lucent (NYSE: ALU) and Qualcomm (NASDAQ:QCOM). Noticeably absent from this group are the backers of WiFiForward, which includes Google (NASDAQ: GOOG), Comcast (NASDAQ: CMCSA), Microsoft (NASDAQ: MSFT), Broadcom, NCTA, Open Technology Institute New America, Public Knowledge and Ruckus Wireless, among others."

Qualcomm, NCTA, auto makers push for 5.9 GHz testing for vehicles - FierceWirelessTech Sep 2015
"Automobile associations, as well as the National Cable & Telecommunications Association (NCTA), Intelsat and Qualcomm (NASDAQ:QCOM) are all asking the FCC, in coordination with the Department of Transportation (DOT) and Department of Commerce (DOC), to conduct thorough testing for the development of vehicle safety technology in the 5.9 GHz band. The 5.9 GHz stakeholders and a group of lawmakers -- Commerce Committee chair Sen. John Thune (R-S.D.) and senators Corey Booker (D-N.J.) and Marco Rubio (R-Fla.) -- sent essentially identical letters to the FCC, DOT and DOC urging them to work together to facilitate testing that could be concluded by Dec. 31, 2019, notes Broadcasting & Cable."

LTE, Wi-Fi delegates collaborate, not clash, during coexistence workshop in Beijing - FierceWirelessTech aug 2015
Despite what appeared to be a lot of defensive posturing before the meeting, there were no fists flying when delegates from the Wi-Fi and LTE communities met over the weekend for a 3GPP coexistence workshop in Beijing to discuss Licensed Assisted Access (LAA) technology. On the contrary, those who attended the meeting, both from 3GPP and Wi-Fi perspectives, told FierceWirelessTech that they were pleased with the degree of collaboration that occurred.

Qualcomm, NCTA continue to battle over FCC regulation of LTE-U, LAA - FierceWirelessTech
"Representatives from Qualcomm (NASDAQ:QCOM) and T-Mobile US (NYSE:TMUS) argued this week that the FCC should not step in to regulate LTE Unlicensed (LTE-U) and related technologies. At a CTIA-organized briefing for reports on Monday, Qualcomm and T-Mobile officials argued that LTE-U can coexist happily with Wi-Fi and that opponents of the technology had not marshalled sound technical reasons for opposing it. Meanwhile, the National Cable & Telecommunications Association, speaking for many cable companies that have their own Wi-Fi networks, hit back hard against Qualcomm. In an FCC filing made public on Wednesday, NCTA said that Qualcomm has not engaged in meaningful collaboration with the unlicensed community, and that its proposals thus far on LTE-U/Wi-Fi coexistence are not fair or equitable.

Gadgets powered wirelessly at home with a simple Wi-Fi router - June 2015
Work is under way to use the Wi-Fi signals that surround us to power our gadgets. . . In Seattle, six households have taken part in an experiment in which modified electrical devices were put in their homes along with a Wi-Fi router. Over 24 hours, the devices were powered solely by the router’s signal, which also continued to provide wireless internet access to the home. ... The hard part is getting the router to constantly push out enough energy, says team member Vamsi Talla from the University of Washington in Seattle. . . . To get around this, the team designed software that broadcasts meaningless data across several Wi-Fi channels when no one is using the internet. ... [The FCC] limits the power of a Wi-Fi broadcast to 1 watt. . . One company with a solution is Ossia in Bellevue, Washington. It has a system called Cota that gets around the FCC regulations by designing a wireless hub that transmits waves at a Wi-Fi frequency but doesn’t send a communications signal.

Sprint, Google, Microsoft, Huawei, TWC and others tap into aggregated Wi-Fi - but revenues remain lethargic - FierceWirelessTech
"A wide range of major companies including Sprint, Google, Time Warner Cable, Huawei and potentially Microsoft are collecting Wi-Fi hotspots as a way to further their respective business goals. . . . However, some of the companies that are doing the actual work of aggregating those hotspots don't have much to show for their efforts--at least, not yet" - "Lowenstein said wireless carriers' business models are completely geared toward encouraging users to buy larger and larger buckets of cellular data. Thus, there's little reason for them to embrace Wi-Fi offloading since it generally gives users more data that they don't have to pay extra for."

Google-backed Sidewalk Labs to take over NYC Wi-Fi rollout - FierceWirelessTech
"Starting this fall, the phone booths in New York City will be replaced with up to 10,000 iconic-looking "links" designed by Antenna Design. The links will offer 24/7 free Internet access up to gigabit speeds, which is more than 100 times faster than average public Wi-Fi, as well as other services such as free phone calls in the U.S., a touchscreen tablet to get information on city services and free cell phone charging, among other things. The digital displays will show public service announcements and advertising. Mayor Bill de Blasio's office expects the five-borough ad network could generate more than $500 million in revenue for the city over 12 years."

In-flight Wi-Fi could potentially open up avionics controls to hackers - RCR Wireless April 2015
“The U.S. Government Accountability Office on April 14 released a report detailing the potential for in-flight Wi-Fi networks to be compromised by cyber attacks.” “Wired reports that particular safety concerns are associated with Boeing’s 787 Dreamliner and the Airbus A350 and A380 models. From that report, those models “have Wi-Fi passenger networks that use the same network as the avionics systems of the planes, raising the possibility that a hacker could hijack the navigation system or commandeer the plane through the in-plane network.” While the passenger portion of the network is separated from the avionics side, that configuration isn’t foolproof.”

Wi-Fi vs EU LBT: Houston, we have a problem - Joey Padden, Lead Architect, CableLabs
"Three coexistence methods commonly appear in contributions to 3GPP so far; channel selection, some form of duty cycling the LTE signal, and Listen-Before-Talk. Combining channel selection and LBT is also quite popular. This post will be the first of a series looking more closely at the pros and cons of each approach."

Public wi-fi report - Analysys Mason Feb 2015
"This latest study from Analysys Mason explores how consumers in the United Kingdom perceive public Wi-Fi services. Analysys Mason surveyed 2000 UK residents for the study. Respondents were asked a number of questions including how often they used public Wi-Fi networks 1 and their impression of public Wi-Fi networks in comparison to cellular networks." Key findings: -- Public Wi-Fi highly relevant for 4G subscribers -- Non-4G subs prefer public Wi-Fi to cellular -- UK mobile subs would like a mix of cellular and public Wi-Fi -- users see mobile operators as most likely provider of public Wi-Fi networks

Automotive radar spectrum in 77 GHz band could work for 5G - PolicyTracker Feb 2015
"The 5G agenda is being pushed by vendors and the academic community, not mobile operators, Varrall told PolicyTracker. The market hype for the current 4G technology centres on data rates. But 4G only deploys easily in high average revenue per user (ARPU) markets such as Japan, the US and, to some extent, Europe, while in other, lower-ARPU markets, operators struggle to achieve return on investment in LTE." "Wi-Fi is increasingly capable and ubiquitous because it's cheap and there are only two bands (2.4 GHz and 5 GHz) to service. LTE, on the other hand, comes in many different flavours, creating a more complex supply chain that leads to fewer economies of scale" "So why 77 GHz? The band is in the middle of the E band allocations at 71-76 GHz and 81-86 GHz proposed for ultra-high bit rate wide area radio systems in the the US defence sector, Varrall said in a recent RTT "technology topic" paper on automotive radar."
