When Trump Phones Friends, the Chinese and the Russians Listen and Learn - The New York Times Oct 2018
"When President Trump calls old friends on one of his iPhones to gossip, gripe or solicit their latest take on how he is doing, American intelligence reports indicate that Chinese spies are often listening — and putting to use invaluable insights into how to best work the president and affect administration policy, current and former American officials said.

Mr. Trump’s aides have repeatedly warned him that his cellphone calls are not secure, and they have told him that Russian spies are routinely eavesdropping on the calls, as well. But aides say the voluble president, who has been pressured into using his secure White House landline more often these days, has still refused to give up his iPhones."

5G mobile network deployment - implications for MNOs and towercos - AnalysysMason Jul 2019
"The number of 5G deployments is increasing worldwide and these deployments are making use of new spectrum and new technologies. Mobile network operators (MNOs) and towercos will need to respond differently to the network architecture and infrastructure requirements for 5G. More specifically, MNOs need to fully understand the costs associated with 5G in terms of both capex (for example, new equipment) and opex (for instance, site rental), whereas towercos must consider how they can maximise revenue from their towers amidst changes to site configurations, while also identifying opportunities to address the changing infrastructure requirements of MNOs. This article discusses how mobile network deployment is changing in response to 5G technology and examines how these changes will affect MNOs and towercos."

radio spectrum auctions. 3G Auction.
"Nokia’s “3G technology” propaganda was in a class of its own. They had done some quite innovative work in stimulating a number of small Silicon Valley companies to try out ideas for Internet type applications on the mobile phones. They were also one of the champions of getting Internet Web site text onto mobile phones using a protocol they called WAP (Wireless Application Protocol).

They showed us a graph of the steep world-wide growth in the numbers of mobile radio customers. This was a curve soaring upwards. They then showed a graph of the steep world-wide growth in the number of customers connecting to the Internet. It was another curve soaring upwards. We were invited to imagine the potential growth that would come from putting the Internet on a mobile phone. A market that would be the imposition of one high growth curve being overlaid on another high growth curve was a very compelling image. The 3G opportunity was an enabling technology to do this."

Exclusive: Russia Carried Out A 'Stunning' Breach Of FBI Communications System, Escalating The Spy Game On U.S. Soil | HuffPost Sep 2019
"Both compounds, and at least some of the expelled diplomats, played key roles in a brazen Russian counterintelligence operation that stretched from the Bay Area to the heart of the nation’s capital, according to former U.S. officials. The operation, which targeted FBI communications, hampered the bureau’s ability to track Russian spies on U.S. soil at a time of increasing tension with Moscow, forced the FBI and CIA to cease contact with some of their Russian assets, and prompted tighter security procedures at key U.S. national security facilities in the Washington area and elsewhere, according to former U.S. officials. It even raised concerns among some U.S. officials about a Russian mole within the U.S. intelligence community."

"American officials discovered that the Russians had dramatically improved their ability to decrypt certain types of secure communications and had successfully tracked devices used by elite FBI surveillance teams."

Joel Brenner: "we were neither organized nor resourced to deal with counterintelligence in networks, technical networks, electronic networks.”

"Russian spies also deployed “mobile listening posts.” Some Russian intelligence officers, carrying signals intelligence gear, would walk near FBI surveillance teams. Others drove vans full of listening equipment aimed at intercepting FBI teams’ communications."

"Original proponents of 5G suggested widespread use of virtual and augmented reality, autonomous cars that need low-latency gigabit connectivity, body-cams, ubiquitous internet of things and many services we cannot currently imagine. However the upgrade to 4G showed that charging customers more did not work. More critically, few consumers will see any benefit from 5G."

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."

5G FWA: more of a challenge than a complement to fixed broadband, AnalysysMason Jun 2019
"Operators tend to think about 5G fixed–wireless access (FWA) in one of two ways:

as a complementary technology, useful only where fibre or cable is uneconomical
as a challenger technology, good enough to exploit deficiencies in existing fixed broadband supply and pricing."

"In neither case is anyone really talking about 5G fully replacing the fixed networks: it is more a matter of degree. Our study suggests that the market opportunity is for about 20–30% of broadband connections in developed economies by 2023, higher in emerging ones. That is an addressable market of 290 million static locations. We forecast that the challenger opportunity will be about twice as large as the complementary opportunity"

"I have argued elsewhere that the capacity angle to 5G tends to get overshadowed by – sometimes incompatible – longer-term thinking centred on new use cases and service-based slicing. The operators that emphasise this brave new world are usually the largest, with deep investment in FTTP or cable. Mobile-only operators often see it differently, and they see the potential immediate, more old-world, benefits of 5G as a capacity play."

Researchers find 36 new security flaws in LTE protocol | ZDNet
"A group of academics from South Korea have identified 36 new vulnerabilities in the Long-Term Evolution (LTE) standard used by thousands of mobile networks and hundreds of millions of users across the world.

The vulnerabilities allow attackers to disrupt mobile base stations, block incoming calls to a device, disconnect users from a mobile network, send spoofed SMS messages, and eavesdrop and manipulate user data traffic."

"The research team's discoveries aren't exactly new. Several academic groups have identified similar vulnerabilities in LTE over the past years on numerous occasions --July 2018, June 2018, March 2018, June 2017, July 2016, October 2015 ... These vulnerabilities have been the driving force behind efforts to create the new and improved 5G standard --which, unfortunately, isn't that secure either, with some researchers already poking holes in it as well."

"They discovered this sheer number of flaws by using a technique known as fuzzing --a code testing method that inputs a large quantity of random data into an application and analyzes the output for abnormalities, which, in turn, give developers a hint about the presence of possible bugs."

"Because the flaws reside in both the protocol itself and how some vendors have implemented LTE in their devices, researchers believe many other flaws still exist in the real world."

Are more MNOs starting to consider shared mobile networks? | PolicyTracker: Feb 2019
"An increasing number of mobile operators are proposing a pragmatic solution for the lack of investment in 5G and high network rollout costs: sharing networks. "

"Spain’s fourth largest mobile network operator (MNO) MásMóvil and regional network provider Euskaltel recently struck a deal to build a 5G pilot shared network."

"Last year, South Africa’s Vodacom and Telkom also reached a network sharing deal. The agreement will allow Telkom customers to roam on Vodacom’s 2G, 3G, and 4G networks from June 2019."

"But Mexico seems to be ahead of almost everyone, as only Rwanda has built a national wholesale mobile network before.

Red Compartida (‘shared network’ in Spanish)–which went live in March 2018–offers broadband to all of Mexico’s telecom carriers, in a move to expand mobile coverage, lower consumer prices and reduce 5G deployment costs."

"Although shared networks remain relatively rare, sharing infrastructure is becoming more common among mobile providers. O2 and Vodafone have just signed an extension to their current network sharing deal in the UK to cover 5G."

3G & 4G Networks Are Prone to Stingray Surveillance Attacks - Jul 2017
"3G and 4G LTE devices deployed worldwide have a critical security vulnerability that could be used by Stingray devices, security researchers revealed at the Black Hat Conference in Las Vegas. Researchers said all the modern and high-speed networks have a protocol flaw that enables mobile devices to connect with the cell operator, allowing attackers to track and monitor users."

"Many believe that the modern protocols, unlike 2G, protect users against easy-to-use tracking and surveillance. However, latest research reveals a flaw in the authentication and key agreement, which enables a phone to communicate securely with the user’s cell network."

"While this flaw doesn’t reportedly allow attackers to intercept calls or messages, it does enable them to monitor consumption patterns and track the phone location."

Opinion | If 5G Is So Important, Why Isn’t It Secure? - The New York Times, Jan 2019
"The Trump administration’s so-called “race” with China to build new fifth-generation (5G) wireless networks is speeding toward a network vulnerable to Chinese (and other) cyberattacks. So far, the Trump administration has focused on blocking Chinese companies from being a part of the network, but these efforts are far from sufficient. We cannot allow the hype about 5G to overshadow the absolute necessity that it be secure."

"Shortly after taking office, the Trump F.C.C. removed a requirement imposed by the Obama F.C.C. that the 5G technical standard must be designed from the outset to withstand cyberattacks. For the first time in history, cybersecurity was being required as a forethought in the design of a new network standard — until the Trump F.C.C. repealed it. The Trump F.C.C. also canceled a formal inquiry seeking input from the country’s best technical minds about 5G security, retracted an Obama-era F.C.C. white paper about reducing cyberthreats, and questioned whether the agency had any responsibility for the cybersecurity of the networks they are entrusted with overseeing."

"T-Mobile, Sprint, and AT&T are selling access to their customers’ location data, and that data is ending up in the hands of bounty hunters and others not authorized to possess it, letting them track most phones in the country."

"The bounty hunter did this all without deploying a hacking tool or having any previous knowledge of the phone’s whereabouts. Instead, the tracking tool relies on real-time location data sold to bounty hunters that ultimately originated from the telcos themselves, including T-Mobile, AT&T, and Sprint, a Motherboard investigation has found. These surveillance capabilities are sometimes sold through word-of-mouth networks."

"For the first time, the U.S. government has publicly acknowledged the existence in Washington of what appear to be rogue devices that foreign spies and criminals could be using to track individual cellphones and intercept calls and messages."

Christopher Krebs, DHS, “noted in the letter that DHS lacks the equipment and funding to detect Stingrays”

"Every embassy “worth their salt” has a cell tower simulator installed, Turner said. They use them “to track interesting people that come toward their embassies.” The Russians’ equipment is so powerful it can track targets a mile away, he said."

"Shutting down rogue Stingrays is an expensive proposition that would require wireless network upgrades the industry has been loath to pay for, security experts say. It could also lead to conflict with U.S. intelligence and law enforcement."

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."

How spies can use your cellphone to find you – and eavesdrop on your calls and texts, too - The Washington Post, May 2018
"The letter [from the Department of Homeland Security to Sen. Ron Wyden (D-Ore.)], dated May 22 and obtained by The Washington Post, described surveillance systems that tap into a global messaging system that allows cellular customers to move from network to network as they travel. The decades-old messaging system, called SS7, has little security, allowing intelligence agencies and some criminal gangs to spy on unwitting targets — based on nothing more than their cellphone numbers."

"Researchers say that SS7 tracking systems around the world now create millions of “malicious queries” — meaning messages seeking unauthorized access to user information — each month."

"Firewalls installed by carriers in recent years block many of the malicious queries, but many others are successful in eliciting unauthorized information from cellular carriers worldwide."

"Criminals last year used SS7 to intercept security codes that a bank texted to its customers in Germany, allowing the criminals to steal money from accounts, according to news reports."

"Carriers worldwide have gradually added better security, but SS7 does not have any way to verify that carriers sending data requests are who they claim to be. The firewalls increasingly installed by carriers, meanwhile, protect their own customers but typically not people who are roaming on the network, said Engel, the German researcher who first reported the security and privacy risks of SS7."

"DHS, which declined to comment for this article, issued a report on SS7 cellphone security in April 2017 that noted the risk to federal personnel"

"The DHS report recommended that carriers adopt new protections. An FCC group, the Communications Security, Reliability and Interoperabilty Council, issued recommendations for improving SS7 security in March 2017 that U.S. carriers have largely adopted

They account for almost ~90% of the U.S. C-band spectrum and service various cable customers across the U.S. for video distribution. However, with spectrum rights expected to expire in mid 2020s and YoY performance on the C-band U.S. business declining fast"

"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?"

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

Abstract:
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.

Astranis Targets Cellular Backhaul with GEO Smallsats - Via Satellite - Mar 2018
"NewSpace startup Astranis is sending its smallsats all the way out to Geostationary Earth Orbit (GEO) to deliver broadband internet. From there, the company intends to work alongside other satellite operators and Mobile Network Operators (MNOs) to meet demand for cellular backhaul."

"Each smallsat will clock in at around 300 kg, and will carry four to six Ka-band spot beams and broader Ku-band beams."

"Astranis’ primary business case rests on using its satellite bandwidth for cellular backhaul. Gedmark believes it comes down to a matter of cost: the reason MNOs are lacking coverage in many regions is because it’s economically unfeasible to build fiber out to far-flung cell towers."

Coverage, not revenue, is increasingly the goal of spectrum assignments | PolicyTracker Feb 2018
"After 20 years and three or four generations of mobile technology, governments and regulators are starting to recognise that there is a contradiction between extracting large amounts of money from mobile operators for spectrum licences and then demanding costly network deployments to cover 100 per cent of a country. That’s according to Gérard Pogorel, Emeritus Professor of Economics at top French graduate engineering school Télécom ParisTech."

"It took the French government six months to arrive at a comprehensive contract with operators to renew 4G licences without new auctions but with strong commitments from them to deploy new networks quickly, Pogorel said. . . . By contrast, the Japanese government, which has never held a spectrum auction, is planning one for March, said Pogorel. "

What is the Future for Mobile Network Operators? CircleID - Paul Budde, Jan 2018
"We have seen the fixed telecom operators slowly being pushed back into the infrastructure utility market.

"Mobile networks are moving in that same direction — that is, the largest part of their network will be a utility, with currently two, three or four mobile infrastructure providers per country and little economic sense for overbuilding the basic infrastructure, the industry is facing serious problems."

"So a convergence is taking place. Increasingly the backbone networks for the mobile operators will mimic the fixed ones, and there will be little room for duplication of these networks. So wireless will increasingly be a retail element rather than a basic network.

"These changes are already reflected in the evaluation of some of the mobile network operators (MNOs) and mobile tower operators. Those of the MNOs are going down while those of the tower operators are going up. This is a clear indication of where the financial market sees the market moving to."

" A holistic approach will be needed instead of one that is aimed at protecting a sharp divide between mobile and fixed networks."

U.S. GAO - Telecommunications: FCC Should Improve Monitoring of Industry Efforts to Strengthen Wireless Network Resiliency
What GAO Found: The number of wireless outages attributed to a physical incident—a natural disaster, accident, or other manmade event, such as vandalism—increased from 2009 to 2016, as reported to the Federal Communications Commission (FCC). During this time, the number of outages substantially increased from 189 to 1,079 outages, with most of the increase occurring from 2009 to 2011.

What GAO Recommends: FCC should work with industry to develop specific performance measures for the Wireless Network Resiliency Cooperative Framework, monitor the framework's outcomes, and promote awareness of it. FCC agreed with the recommendations.

That Time When Intelsat, Inmarsat and SES Joined to Defend Spectrum - From our Archive - Via Satellite -Via Satellite
"In 2007, Via Satellite awarded its Satellite Executive of the Year honors to three leading spectrum executives from operators Intelsat, Inmarsat and SES for crafting a unified message that helped preserve C-band spectrum access for the industry. Ten years later, Intelsat and Intel have made waves with a joint FCC proposition that opens the door to sharing C-band spectrum with mobile operators. Looking back to our 2007 SEOTY award winners explains some of the history behind the strong response to the proposal."

"The satellite industry’s use of C-band spectrum faced a serious threat in 2007, but a well-organized effort involving satellite players around the globe fended off terrestrial companies seeking a foothold in the band."

"The scope and complexity of this effort involved representatives from companies around the globe, and the task of keeping the different satellite-related companies unified in their message and organized through the months leading up to WRC-07 and throughout the meeting was a gargantuan one."

"We were aware of the WRC agenda item since WRC-03. However, the responsibility for this issue had been placed in ITU Working Group 8F, which was dominated by supporters of IMT."

"It has been a wake-up call in the sense that the message is now loud and clear — we are fighting for spectrum in competition with emerging terrestrial wireless services, both to keep our existing operations intact as well as to grow our own new services including mobile and broadband."

Sprint tests flying Magic Box | FierceWireless, Sep 2017
"Magic Box, which is given free to Sprint customers who qualify, has proven to be a very useful product to get coverage where it’s needed, according to Günther Ottendorfer, COO of technology at Sprint. Then Sprint came up with another idea: use it for certain applications to provide coverage from the air."

"The aerial small cell is designed to be a rapidly deployable solution capable of extending Sprint’s 2.5 GHz data service initially up to 10 square miles. It can be used after natural disasters or for special events, like sports or concerts."

Verizon’s Palmer: ‘Our network is an absolute beast,’ resilient in wake of hurricanes | FierceWireless, Sep 2017
Nicola Palmer, chief network officer at Verizon: “Our network is an absolute beast,” she said. “It is so resilient and so layered” that it can withstand an amazing amount of what Mother Nature can dish out. In Florida, 92% of sites reportedly were up line, she said, with reports out by the FCC. “I’m anxious to get down there and get my boots on.”  

"Palmer said the resiliency of Verizon’s network is all due to careful planning before disasters strike, and they plan every year. “You don’t make the calls on game day,” she said. It’s about things like architecture, the back-up power strategy, generator penetration and batteries. “We didn’t have a single switch location that lost connectivity or power” because of the architecture and forethought."

Industry Voices—Madden: A shake-up is coming to RRH semiconductors for LTE base stations | FierceWireless
"In the market for mobile infrastructure, the change to Massive MIMO is shaking up the established order. Comfortable players like Xilinx and Analog Devices are developing radically different and new semiconductor modules to capture a larger share of the future market, with higher levels of integration. As one simple example, we will see integration of data converters with the digital front end, to cut power consumption by 40%. The size of the radio will shrink by 70% or more, so that the OEMs can line up 64 radios together in a Massive MIMO array. It’s not your father’s base station anymore."

"For the 80-100 chip vendors that support the RRH, this year is a critical time. Each supplier must choose a direction for 2018-2019 products, and the uncertainty around 16T16R or 128T128R is paralyzing many of them. But there’s no time to wait: The wide bandwidth and high performance required in 5G will drive a new profit cycle in RF semiconductors, so chip vendors can’t miss the 2019-2020 wave of deployment."

SRG on wireless carrier support for drones: 'No one operator really stood out' | FierceWireless, May 2017
SRG looked at commercial LTE systems from Sprint, AT&T, T-Mobile and Verizon Wireless to see what their coverage is like for the most basic functions of a drone—command and control (C2). Terrestrial cellular networks are designed to provide coverage from zero to 10 feet above ground, not 400 feet, but the analysts noted that several network operators are touting their network performance for drone coverage and they wanted to see for themselves how well the networks could support unmanned aerial systems (UAS).

Coexistence of new services in the 700 MHz band with digital terrestrial television - Ofcom May 2017
"This consultation presents our technical analysis of coexistence issues between future mobile services in the 700 MHz band and digital terrestrial television (DTT) in the adjacent band.

The 700 MHz spectrum band currently houses DTT and wireless microphones used for programme making and special events (PMSE). In November 2014, Ofcom decided that the 700 MHz spectrum band would be repurposed for mobile data services. At that time we also presented results of our initial work on coexistence issues.

We have now completed more detailed work to investigate the nature and scale of potential interference risks. We also discuss technical aspects of some potential solutions to mitigate the risks."

AT&T Labs working to combine drone video footage with artificial intelligence monitoring | FierceWireless
"AT&T Labs is researching ways to take video footage from a drone flying around an AT&T cell tower and use AI to analyze that footage for signs of rust, corrosion or other defects on the tower. The result would save AT&T the time and money it takes to have engineers physically climb cell towers to do inspections (thanks to the drone), as well as the time and money it takes to have engineers review video from a drone inspecting a tower (thanks to the artificial intelligence)."

"Pregler’s drone team has been looking at ways to use drones to provide cell coverage in areas where the carrier doesn’t currently offer service, or where it needs to provide extra coverage."

"AT&T’s helicopter drone also carries a long tether cable that connects it to a box on the ground."

Verizon and Charter: the Trump era heralds a wave of European-style cable–mobile consolidation - AnalysysMason Jan 207
"Seeing every Verizon move through the teleology of 5G misses the point; US mobile is shrinking and Verizon needs to spread its bets."

"In pursuing a mobile-first strategy, Verizon has progressively shrunk its wireline footprint. In the early part of last decade, the company was a proponent of FTTP, but found the capex burden intolerable, and of its 22% wireline coverage, only 15% has FiOS (FTTP) availability, with the rest on low-grade ADSL. Charter acquired the larger Time Warner Cable and the smaller Bright House Networks in 2015."

"Analysys Mason's view is that the USA is waking up to the same realities that hit Europe a few years ago: a mobile-first strategy no longer makes any 'industrial' sense, and the survival of mobile-only operators into the 5G era is in question. Market structure (with a geographical fragmentation of fixed but not mobile) has shielded the USA from this, as it has in other markets with a similar asymmetric structure such as Finland and Russia. While 5G-readiness is something to aspire to, the rationale for any merger is, from Verizon's point of view, much more immediate and banal: mobile revenue will come under increasing pressure; broadband/video has more growth potential than mobile; and fixed–wireless may not work."

"Analysys Mason forecasts rises in consumer wireline revenue and a decline in mobile revenue between now and 2021 in the USA."

"We believe that Verizon's interest in cable is at least in part motivated by the realisation that mmWave fixed–wireless (pre-standards 5G) is not the best way to address the great indoors."

New App Detects Government Stingray Cell Phone Trackers - Slashdot - Jan 2015
"SnoopSnitch scans for radio signals that indicate a transition to a stingray from a legitimate cell tower. "SnoopSnitch collects and analyzes mobile radio data to make you aware of your mobile network security and to warn you about threats like fake base stations (IMSI catchers), user tracking and over-the-air updates." say German security researchers Alex Senier, Karsten Nohl, and Tobias Engel, creators of the app which is available now only for Android. The app can't protect people's phones from connecting to stingrays in the first place, but it can at least let them know that there is surveillance happening in a given area."

How To Detect And Find Rogue Cell Towers | Hackaday Aug 2016
"From what we saw at HOPE in New York a few weeks ago, we’re just months away from being able to put a femtocell in a desktop computer for under $3,000. In less than a year, evil, bad hackers could be tapping into your cell phone or reading your text message from the comfort of a van parked across the street. You should be scared, even though police departments everywhere and every government agency already has this capability."
"For the last few months [Eric Escobar] has been working on a simple device that allows anyone to detect when one of these Stingrays or IMSI catchers turns on. With several of these devices connected together, he can even tell where these rogue cell towers are."
"To build his rogue-cell-site detector, [Eric] is logging this information to a device consisting of a Raspberry Pi, SIM900 GSM module, an Adafruit GPS module, and a TV-tuner Software Defined Radio dongle."
