Security Lab researchers reveal how smart devices can be turned into surveillance devices with music
Researchers from the Allen School’s Networks & Mobile Systems Lab and Security and Privacy Research Lab teamed up on a new project, CovertBand, to demonstrate how smart devices can be converted into surveillance tools capable of secretly tracking the body movements and activities of users and their companions. CovertBand turns off-the-shelf devices into active sonar systems with the help of acoustic pulses concealed in music. The team’s findings reveal how increasingly popular smart home assistants and other connected devices could be used to compromise users’ privacy in their own homes — even from half a world away.
“Most of today’s smart devices including smart TVs, Google Home, Amazon Echo and smartphones come with built-in microphones and speaker systems — which lets us use them to play music, record video and audio tracks, have phone conversations or participate in videoconferencing,” Allen School Ph.D. student and co-lead author Rajalakshmi Nandakumar told UW News. “But that also means that these devices have the basic components in place to make them vulnerable to attack.”
As fellow author and Ph.D. student Alex Takakuwa points out, “Other surveillance approaches require specialized hardware. CovertBand shows for the first time that through-barrier surveillance is possible using no hardware beyond what smart devices already have.”
CovertBand relies on repetitive acoustic pulses in the range of 18 to 20 kHz. While that is typically low enough that most adults are unlikely to pick up on the signals, young people and pets might — and an audible volume is required for more distant surveillance or to pick up activity through walls. To get around this, the team found that they could disguise the pulses under a layer of music, with repetitive, percussive beats the most effective at hiding the additional sound.
“To our knowledge, this is the first time anyone has demonstrated that it is possible to convert smart commodity devices into active sonar systems using music,” said Allen School professor and co-author Shyam Gollakota.
By connecting a smartphone to a portable speaker or flat-screen TV, the researchers discovered they could use the data collected through CovertBand to accurately identify repetitive movements such as walking, jumping, and exercising up to a distance of six meters within line of sight, and up to three meters through walls. Having proven the concept, researchers believe a combination of more data and the use of machine learning tools would enable rapid classification of a greater variety of movements — and perhaps enable the identification of the individual making them.
With CovertBand, Allen School researchers have identified a plausible threat, given the increasing ubiquity of these devices in our pockets and in our living rooms. But our embrace of emerging technologies needn’t end on a sour note. As professor and co-author Tadayoshi Kohno points out, when it comes to cybersecurity, knowledge is power.
“We’re providing education about what is possible and what capabilities the general public might not know about, so that people can be aware and can build defenses against this,” he said.

Over the past 30 years, fiber lasers have gradually become a premier technology in the industrial coding and marking field. Invented by American physicist Dr. Elias Snitzer in 1961, fiber laser systems were largely used for niche applications before technical advancements in the 1980s and 1990s allowed them to be used for industrial marking and cutting applications. Today, fiber lasers, alongside CO2 laser marking systems, are considered to be among the best coding technologies on the market.
The popularity of fiber laser marking machines is largely attributed to their ability to mark non-organic materials. Fiber laser systems produce wavelengths 10 times shorter than CO2 systems. In many cases, materials that cannot be marked by wavelengths produced by CO2 lasers can be marked with a fiber laser marking system. The ability of materials to absorb the shorter wavelength from a fiber laser creates a contrast, color change, or surface distortion in the substrate. Fiber lasers use the same marking delivery method as CO2 laser marking systems and have the ability to mark high-density materials like rigid plastics, steel, and aluminum, expanding the applications they can be used for.
However, not all fiber laser marking machines are created equal. If you’re on the search for a fiber laser system for your operation, here’s what you need to know.
When considering which fiber laser system will work best for you, several factors will guide your search. The most obvious starting point is confirming the machine is well-suited for marking applications. There are many fiber laser systems on the market, including models that are best suited for welding, drilling, and cutting applications.
The systems designed for welding, drilling, and cutting most often utilize continuous-wave beams as opposed to marking systems that typically utilize pulsed beams. While some fiber laser systems can generate both beam outputs, it’s essential to know that your potential system choices will generate the appropriate beam for your needs.
Beam output similarly affects which materials the system can mark and how quickly. Consequently, it’s essential to ask the following questions while searching for a laser marking system:
It’s important to determine the effectiveness of the laser marking system to produce the desired throughput and quality of the marking application. Always test the exact material to be marked with the exact laser marking system you intend to use.
A marking application must be evaluated thoroughly. Factors to consider include:
With this information, you should be able to find the best fiber laser marking machine to fit your operational needs. Next, we’ll look at the best places to begin your search.
As one of today’s premium marking technologies, fiber laser systems are available from a variety of sources. However, there are a few laser companies that maintain higher profiles than their competitors. To begin your fiber laser system search, we recommend starting with these five businesses:
Headquartered in Ditzingen, Germany, Trumpf has been manufacturing and distributing industrial equipment for nearly 100 years. It first entered the laser market by creating its own CO2 systems in the mid-1980s, and now it offers a wide range of laser systems, including its flagship fiber laser model, the TruFiber.
Compatible with stainless steel, titanium, aluminum, and copper, as well as plastics and textiles, TruFiber systems use pulsed beams to perform marking applications. To meet the needs of differently-sized businesses, TruFiber systems are available in different models, ranging from the high-powered TruFiber P to the compact TruMicro Series 2000.
Since 1974, Japanese company Keyence has kept a high international profile in the coding and marking industry. Known in the industrial printer sector for its continuous inkjet models, it’s also active in the fiber laser field, where its MD-F Series systems are widely popular.
Keyence differentiates MD-F Series fiber laser machines from the competition by focusing on its “Wobble Control,” i.e. the MD-F system’s circular marking pattern. Conventional laser systems mark materials by creating a series of overlapping single lines. In contrast, MD-F Series lasers are moved in circular patterns, keeping the energy more highly concentrated and thus more effective.
A titan of industrial printing, Domino Printing Sciences is one of the biggest names in the coding and marking industry. It first gained its reputation by designing high-powered continuous inkjet systems in the 1970s, but in August 1994, it expanded its product portfolio to include laser marking systems. Before long, Domino’s laser marking systems were adopted by some of the biggest companies in the world, including Dr. Pepper.
Today, Domino’s top fiber laser option is the F720i. Designed for use on industrial canning lines, the F720i fiber laser can mark up to 100,000 cans per hour with high-quality, fully traceable codes. Further, the system is designed to resist the challenging elements commonly found in industrial canning environments, such as high humidity, temperature changes, and sugar-filled air. As a result, the F270i is capable of delivering long periods of extended uptime for maximum efficiency.

Each year, new technologies rise and fall, sometimes making an impact on our daily lives and other times barely leaving a trace. One category of emerging technologies that has the widest variety is the Internet of Things or IoT.
Someone who works for an Internet of Things (IoT) software company, the frequently asked question will be what is IOT?
It is defined as, A system of interrelated computing devices, mechanical and digital machines, objects, animals or people that are provided with unique identifiers and the ability to transfer data over a network without requiring human-to-human or human-to-computer interaction.
Let’s see the simple explanation of the Internet of Things(IOT), it means that internet connection is the most valuable thing which benefit us in all terms, from calling & reading books to watching movies & news.
The point is that connecting things to the internet yields many amazing benefits. We’ve all seen these benefits with our smartphones, laptops, and tablets, but this is true for everything else too.
The Internet of Things is actually a pretty simple concept, it means connecting all the things in the world to the internet.
The confusion arises in your mind because there are so many examples and possibilities in IoT. To understand the benefits of connecting things to the internet. We should firstly connect everything to the internet.
When something is connected to the internet it means that it can send information or receive information. This ability to send or receive information makes things smart.
Let’s take smartphones as an example. we can listen to just about any song in the world, but it’s not because your phone has every song stored on it but it’s because every song is stored somewhere else, where your phone can send information (asking for that song) and then receive information (streaming that song on your phone).
A thing doesn’t need to have storage or a computer inside, but it needs to connect.
In the Internet of Things, all the things that are being connected to the internet can be put into three categories:
- Things that collect information and then send it.
- Things that receive information and then act on it.
- Things that do both.
And all three of these have enormous benefits that feed on each other.
Collecting and sending information means sensors. It could be temperature sensors, motion sensors, moisture sensors, air quality sensors, light sensors, and many more. These sensors with a connection, allow us to automatically collect information from the environment which allows us to make more intelligent decisions.
On the farm, automatically getting information about the soil moisture can tell farmers exactly when their crops need to be watered. Instead of watering too much (which can be an expensive over-use of irrigation systems) or watering too little (which can be an expensive loss of crops), the farmer can ensure that crops get exactly the right amount of water. More money for farmers and more food for the world!
Just as human senses, we are able to smell, taste, feel, and hear. Machines have sensors that make them sense the world.
We’re all very familiar with machines getting information and then responding. Your printer receives a document and it prints it. Your car receives a signal from your car keys and the doors open and many more.
The real power of the Internet of Things arises when things can do both of the above. Things that collect information and send it, but also receive information and act on it.
Kevin Ashton, co-founder of the Auto-ID Centre at MIT, first mentioned the internet of things in a presentation he made to Procter & Gamble (P&G) in 1999. Wanting to bring radio frequency ID (RFID) to the attention of P&G’s senior management, Ashton called his presentation “Internet of Things” to incorporate the cool new trend of 1999.
Let’s quickly go back to the farming example. The sensors can collect information about the soil moisture to tell the farmer how much to water the crops, but you don’t actually need the farmer. Instead, the irrigation system can automatically turn on as needed, based on how much moisture is in the soil.
You can take it a step further too. If the irrigation system receives information about the weather from its internet connection, it can also know when it’s going to rain and decide not to water the crops today because they’ll be watered by the rain anyways.
And it doesn’t stop there! All this information about the soil moisture, how much the irrigation system is watering the crops, and how well the crops actually grow can be collected and sent to supercomputers that run amazing algorithms that can make sense of all this information.
And that’s just one kind of sensor. Add in other sensors like light, air quality, and temperature, and these algorithms can learn much more. With dozens, hundreds, thousands of farms all collecting this information, these algorithms can create incredible insights into how to make crops grow the best, helping to feed the world.
As you can see from these Internet of Things examples, the future of IoT is a bright one. As new innovations emerge about how best to use IoT products, it will be interesting to see which way this technology heads.

The levels discussed here are probably irrelevant to any practical application.
This is a silly topic, but there’s a slight chance it might help someone troubleshoot something, someday.
Here is an FFT of an A-grade E1DA Cosmos ADC with nothing plugged in. The settings are unreasonable; 160 averages of 4M Length: about 2 hours of data collection. This was taken with input set to 1.7V, mono mode (summing both channels).
Almost perfect white noise spectrum, with only a bit of low frequency rise. The chart starts at 2Hz so performance is better than it looks at first glance. With these settings the white noise is -187dBFS at 1kHz.
The mains noise is a barely visible -184dBFS blip at 60Hz; not remotely measurable in any reasonable test suite. This is plugged into the front USB port on a desktop PC, and with the input impedance set to 640Ω.
Mains noise increases slightly to -182dBFS when the input is set to 10V (3.84kΩ input impedance).
“Shorting” the input makes the mains noise disappear but otherwise has no significant effect on the noise level. This was taken using a 10.4Ω balanced dummy load to ground, on the 10V input setting. If I had to guess, it looks like the mains noise is dominated by bias/leakage current over the input resistor. Levels this low indicates that the OPA2156’s more robust input specs (aside from noise) compared to the OPA1612 wouldn’t have any practical advantage as the input in this scenario.
Miscellaneous external tests (not relevant to Cosmos ADC performance)
Now with a 30cm XLR Y-splitter cable plugged in. This type of cable is normally required to take measurements in summing mode. The cable itself was left dangling in midair to prevent it from touching anything. A much lower FFT length and averaging was used for this test, so the broadband noise level is not comparable to the tests above. Mains noise has jumped to -161dBFS. This goes away when the input pins are shorted (and as a result is likely not present in actual measurements).
This may look significant compared to the charts above, but this level of mains noise probably isn’t relevant. It is much more pronounced than before, but has practically no effect on the overall noise (still orders of magnitude below the RMS white noise level, which has remained unchanged). APx555 charts typically set the Y-minimum at -160dBr, so this level of noise wouldn’t even be visible on those graphs.
This measurement is with a unibody metal XLR to 1/4″ TS adapter plugged in. This adapter shorts XLR pins 1 and 3 to the connector shell. Despite being much smaller than the Y-splitter cable, it has significantly higher mains noise, enough to reduce the overall noise performance by 1.5dB.
It also introduces a new spray of spuriae previously unseen on any graphs, which all appear to be odd-order harmonics of the mains fundamental.
Connecting a function generator, 1Vpp 1kHz, across XLR pin 1 and the connector shell, produces the above. Note that the FFT length and averaging are different, so the broadband noise levels are not comparable to the other tests. I didn’t verify whether the function generator actually output 1Vpp (doubtful since the load impedance was almost zero). Measuring pin 1 and the connector shell directly at the ADC (nothing plugged in) show that they are shorted together (or at the very least have a low resistance between them); likely they are both attached to ground. In other words, injecting a signal between the two ground inputs, presumably between the chassis and signal grounds, produces something measurable; the two grounds are not connected at the input.
Shorting the two grounds together doesn’t seem to measure any different from an open circuit (not pictured). Perhaps this changes when connected to an actual input with actual current (not tested).

It's a reality : Microsoft has announced, November 7th, the end of Windows Live Messenger for 2013.
The instant messaging service, launched on 1999 as "Microsoft Network Messenger" (MSN), became one of the most popular. With the acquisition of Skype in May 2011 (for more than $ 8,5 B, about 6 B €), both services are duplicated : Skype allows users to send instant messages, like Messenger.
Windows Live Messenger will disappear on 2013, but it will not be of a technical point of view : "Skype is moving from a P2P service to a modern, suitable for mobile devices" said The Verge website.
Thus, Messenger will not disappear completely. "Skype and Messenger meet", said Tony Bates, Microsoft's head.

On the new Macbook Pros the issue of Bluetooth interfering with WiFi network is really bad. So bad that I could not use my bluetooth mouse while surfing the internet!
The issue is caused by the fact that both bluetooth and most WiFi network use frequencies near 2.4Ghz; signals are then overlapping and disturbing each other. So, some slight interference, is normal and maybe it’s more serious on the rMBP because it has a single card to handle both WiFi and BT.
The solution consists in setting priorities between WiFi and bluetooth (giving WiFi signal an higher one).
You have to launch the Terminal (Applications>Utilities>Terminal), paste the following code, press Enter and insert your admin password.
sudo defaults write /Library/Preferences/com.apple.airport.bt.plist bluetoothCoexMgmt Hybrid
The problem, in facts, is not solved. It can’t be solved, if radio signals are using the same frequencies. But, at least, I am able to use the internet with my mouse (that’s a pretty basic task :D)
The real solution would be to use different frequencies for the WiFi network: to avoid this kind of issues, WiFi is also available in 5Ghz frequencies, however just a few routers support that.
If yours do, all you have to do it to enable it in the settings page.
Please note that 5Ghz WiFi has a shorter range since higher frequencies can’t pass through objects and walls like lower ones do. Some routers even support both frequencies, so your devices can use the 5Ghz when in range, and 2.4Ghz otherwise.
However, if you don’t want to upgrade your router, the command I wrote about earlier is a great trade-off!

The Nintendo GameCube Broadband Adapter is an attachment for the Nintendo GameCube to connect via LAN with another Nintendo GameCube console. A few games can employ this connection for multiplayer purposes, such as Mario Kart: Double Dash!! and Phantasy Star Online Episode I & II. The second game is even compatible with the ASCII Keyboard Controller, allowing them to communicate to others while playing online. To connect, owners of the Nintendo GameCube Broadband Adapter must register their network cards and configure the systems for the DHCP server. Some games can support up to eight consoles connected if each system plays from a disc of the same game.


As a professional drone service provider, Autel Robotics' launch of enterprise drones has affected the entire drone market and brought huge competition. In the list of commercial drones, Autel Robotics has a total of five drones, namely Autel EVO II Dual 640t, Autel EVO II Pro RTK, Autel EVO II Dual 640T RTK, Autel EVO II Pro Enterprise, Autel EVO II Dual 640T Enterprise .
Don't know enough? We will explain from the following angles.
1. Both have a foldable design and the color is orange.
- The propeller blades used by the EVO II enterprise will be longer and can replace the propeller blades of the EVO II RTK series, but it will affect the battery life.
- EVO II RTK series drones cannot use the propeller blades of EVO II enterprises, which will affect the motor load and cause safety accidents.
The EVO II RTK series supports 36 minutes of flight in a windless environment, and the EVO II Enterprise RTK also has a battery life of 36 minutes in a windless environment, but the EVO II Enterprise can carry different loads. Therefore, the flight time can reach 42 minutes with no load, 38 minutes with night lights, 29 minutes with searchlights, and 34 minutes with megaphones.
Both the EVO II RTK series and the EVO II Enterprise series include two drones, Autel EVO II Pro RTK, Autel EVO II Dual 640T RTK, Autel EVO II Pro Enterprise, Autel EVO II Dual 640T Enterprise. EVO II Pro carries 6k Camera, the EVO II Dual 640T carries an 8k camera and thermal imager.
Image Transmission Performance
The EVO II RTK series supports 9 kilometers of image transmission, and the EVO II enterprise series supports up to 13 kilometers of image transmission.
RTK Module Difference
Both the EVO II RTK series and the EVO II Enterprise RTK use the same RTK module to achieve centimeter-level precise positioning with the same positioning accuracy. At the same time, the two also support network RTK, support PPK, and include microsecond time synchronization.
The EVO II RTK series is no different from the EVO II enterprise RTK connection. It needs to be connected through the APP. The remote control obtains the real-time differential data of RTCM3.0/RTCM3.1/RTCM3.2 through the local map transmission connection or 4G network.
RTK Base Station Mode
The EVO II RTK series uses the same base station model as the EVO II Enterprise RTK.
There are three supported RTK base station modes:
- Support remote control to connect to local RTK base station (A-RTK high precision positioning system) ( RTCM 2.X/3.X );
- Support the remote control to connect to the default network RTK service (RTCM3.2) through the 4G network; (free for the first year in China, and purchase for the second year);
- Support custom network RTK service based on N-Trip account connection (RTCM3.0/RTCM3.1/RTCM3.2)
Both EVO II RTK series and EVO II Enterprise RTK use the same RTK module, so the format of the file record is the same, with the following file formats:
- EVENTLOG.bin is the exposure timestamp log file in binary format;
- PPKRAW.bin is the mobile terminal satellite observation data and ephemeris data in RTCM3.2 MSM5 format;
- Rinex.obs is the transcoded Rinex observation file;
- Timestamps.MRK is the clear exposure timestamp in ASCII format, the location result of each photo at the time of taking the photo, the location status at the time of taking the photo, the standard deviation of the location, and the record file such as the time of taking the photo.


Traffic flows across a network in two directions - inbound and outbound. Proper filtering of this traffic ensures that a network is functioning as intended in a secure and efficient manner.
Inbound, or Ingress filtering, protects a network from invalid traffic originating from outside the network by blocking this traffic when it enters the network.
Outbound, or Egress filtering, ensures that your network does not transmit invalid traffic to remote networks.
Proper filtering can reduce the ability for a remote attacker to easily use spoofed packets and Man-in-the-Middle attacks across the network edge by disallowing traffic that meets certain specifications.
As an example, an attacker will often attempt to spoof a trusted host on the target network in order to abuse a trust relationship between two machines on your network. With proper Ingress filtering, the remote attacker's packets will never reach their intended target as the spoofed network address should never attempt to connect to the target machine from an outside interface.
Alternatively, the well-known and abused "un-routable" network spaces reserved for private use can be used to circumvent certain firewall implementations for the purpose of information retrieval and network mapping, and as a precaution, should be filtered on all edge routers.
These abused address spaces are generally called Bogons, and are defined as Martian blocks [Private (reserved for non-Internet usage) and reserved address spaces (multicast, experimental, future use) RFCs 1918, 3330] and blocks that are not currently assigned to a designated registry organization. Bogons should be filtered on both the inbound and outbound directions on all network interfaces that are open to the Internet. In reality, these Bogons should be filtered in all network devices regardless of their location or function, as such filtering when applied on a widespread scale will reduce the total amount of abusive Internet traffic.
It is important to note that the Bogon list is dynamic, and regularly changes as new block spaces are assigned and released, so regular updates will be required for comprehensive coverage. Publicly available Bogon lists are by no means a complete filtering solution, but are a great place to begin when identifying troublesome address spaces during the creation and deployment of any filtering solution. More information on the Bogon list can be found at the Team Cymru Bogon Reference at http://www.team-cymru.org/Services/Bogons.

Connection problems with Intel Centrino Advanced-N 6230 and Linksys WRT54G router
Using my new Dell XPS 15 (LX502) with an Intel Centrino Advanced-N 6230 wireless card I couldn't connect to my WRT54G router running the Tomato firmware anymore. Neither WPA nor WPA2 worked, not even WEP. Turns out that I had "Afterburner" mode enabled, which seems to cause problems, as also described here. After disabling this feature in the Tomato interface, everything worked nicely again.

Bevan Slattery is recognised as one of Australia’s leading entrepreneurs having founded some of Australia’s most successful technology companies.
In 2002, Slattery co-founded PIPE Networks which grew to become Australia’s largest Internet Exchange and Australia’s third-largest metropolitan fibre network provider – with over 1,500km of fibre in five cities connecting 80 data centres, 250 Telstra exchanges, and over 1000 buildings. In 2008, PIPE Networks proceeded with the construction of the $200m Sydney to Guam cable (PPC-1) with the project being completed in October 2009. PIPE Networks was sold to TPG for an enterprise value of $420m in May 2010.
In 2010, Slattery founded NEXTDC Limited (ASX: NXT), with a vision to become Australia’s largest independent data center provider. Having raised over $200m, NEXTDC launched data centres in Brisbane, Canberra, Melbourne, and Sydney, and began works in Perth, making NEXTDC Australia’s largest data centre provider in terms of geography and IT power capability.
In 2013, Slattery established Megaport (ASX: MP1) as the world’s first SDN-based elastic interconnection platform designed to provide a secure, seamless, and on-demand way for enterprises, networks, and services to interconnect. Bevan successfully launched Megaport in Australia, New Zealand, Singapore, and Hong Kong before the business was acquired by Megaport Limited in August 2015. Bevan oversaw Megaport’s listing on the ASX in December 2015.
Also in 2013, Slattery founded Superloop Limited (ASX: SLC) with a vision to become the leading independent provider of connectivity services across the Asia Pacific region and the US. Superloop was listed on the ASX in July 2015.

SPORTSAFE UK – IRIS
SportsafeUK supply, install and service sports equipment nationally. Their on-site services are conducted by over 40 engineers, who used an Excel-based system and emailed daily service reports. This slow, inconsistent process was inaccurate, costly and impacting other business functions.
ECS designed and implemented IRIS; a bespoke, fully integrated software solution, running on tablets. IRIS communicates seamlessly with two internal systems and enables managers to monitor and control the work, with completed reports automatically distributed.
ECS’s approach in standardising the process reduced the time taken to complete a service report from over 2 days to within 2 hours. It is now far simpler to train new engineers; paper records have been significantly reduced and SportsafeUK have made dramatic savings. The IRIS system has improved their customer experience and the entire business process has become more efficient – with quicker quote generation and faster follow-up on sales leads.
What they said
I have had the pleasure of working with the ECS Team throughout the development of IRIS. At over 25,000 visits per year across the whole country…the way the tablet creates the report for the customer to see whilst our team is still on-site has received great feedback from our 120 councils in the UK.
Our internal processes have sped up to a point where customers receive their quote and report the same day as the inspection…the report feedback direct from the customers is very positive.
The company is now looking at IRIS V2; this will take the system further forward and increase productivity across the business.”

Traffic Signal Coordination
The City of Peoria attempts to coordinate the traffic signals to provide safe and efficient traffic flow throughout the City. The ability to provide good coordination on a corridor is generally a function of signal spacing, prevailing traffic speed, amount of traffic, roadway capacity, signal cycle lengths, and conflicts with other major roadways. Not only does traffic signal coordination serve the greater good of the traveling public, but also has the added benefit of reducing fuel consumption and emissions because it reduces overall traffic delays.
In addition, except for in the Central Business District, most Peoria traffic signals use video or pavement loop detection systems to actuate the signal timing. This allows the signal to adjust the length of a phase of traffic, such as a left turn, to accommodate the current traffic load. This type of system helps clear the intersection and reduce the overall traffic delay. Another benefit of actuated signals is that they allow the controller to know when a vehicle from the side street approaches the intersection, which is particularly important at night because it allows the signals to maintain green signals on the main road and only call for the side street green to be activated when needed.
A majority of the signals in Peoria are coordinated, however, some are not. Signals that are in isolated locations or in too tight of a network do not lend themselves to good coordination. These intersections are often run in a free mode and change on the demand of traffic volumes. In the downtown area, where the streets are laid out in a grid fashion, it has been found that the signals run more efficiently pre-timed with short cycle lengths. The downtown intersections are still coordinated on some of the streets that have good progression, however, on other downtown streets, that do not have good progression because of the close proximity of the intersections, they are not coordinated.

In the second quarter China took over the position once held by the US as the world’s top smartphone market, with 33.1 million handsets in shipments, more than the 25 million handsets shipped in the US.
Since the start of the second quarter China’s smartphone shipments have passed those of conventional mobile phones. In June smartphones accounted for 56.9% of China’s mobile phone market.
The explosive growth is attributed to the introduction of budget-priced smartphones made possible by a sharp drop in hardware costs. Smartphones priced below 1,000 yuan ($157) cost less than 400 yuan ($63) to produce, according to Southern Daily.
Budget smartphones flooded the market during the first half of this year after China Unicom introduced them in the second half of last year, prompting China Mobile and China Telecom follow suit.
China’s smartphone shipments in the first quarter skyrocketed 164% over the same period of last year to 33.1 million handsets, according to data from the US-based asset-management firm Needham & Company.


We had so much fun creating interactive content for the last Data Digest that we decided to do it again. Today we present an interactive map showing broadband internet availability in the Coachella Valley. CVEP has long championed high-speed internet availability as a crucial component of attracting and retaining businesses in the valley. Remote-work households considering relocating to our valley look for high-speed internet when contemplating a move. While broadband access has improved, we have a long way to go. Click here to explore the map.
Our interactive map utilizes layers produced by Esri that compute a broadband score based on Federal Communications Commission (FCC) Form 477 data. The FCC requires “all facilities-based broadband providers to file data with the FCC twice a year (Form 477) on where they offer Internet access service at speeds exceeding 200 kbps (0.20 megabits per second) in at least one direction. Fixed providers file lists of census blocks in which they can or do offer service to at least one location.” You can zoom into this map to get this census block level data.
The FCC’s minimum standard for broadband of 25 Mbps download and 3 Mbps upload sets the broadband score at 100. That score is then weighted by the population in the area, the population served by different speeds, and breakdowns of race/ethnicity. The map layers have been color-coded to show speeds above and below this FCC standard of 100. Red/orange areas are below the standard, and green areas are above. These data are updated twice yearly, but the FCC takes a while to compile them. The most recent data in these maps is for June 2021.
Because the score is calculated in real-time based on the user’s selection, we have filtered the data just for Riverside County, for performance issues. This map shows Western Riverside County east to the Coachella Valley. At this scale, we are seeing Census tract data. Note how Western Riverside County has much more contiguous high-speed access in the aggregate, while the Coachella Valley has much less. Be aware that at the Census tract level, the broadband scores are computed for a much larger area. If we zoom in, the scores become more nuanced. Still, at this scale, only five census tracts in the Coachella Valley have aggregated broadband scores above the FCC standard.
We see the most granularity at the Census Block level. This is the geographic level for which the FCC requires data for Form 477. For each geographic level, a pop-up block of text details the characteristics of broadband access for the chosen block.


Jeremy Naydler, Wake Up World
In November last year (2018), the United States Federal Communications Commission (FCC) authorized the rocket company SpaceX, owned by the entrepreneur Elon Musk, to launch a fleet of 7,518 satellites to complete SpaceX’s ambitious scheme to provide global satellite broadband services to every corner of the Earth. The satellites will operate at a height of approximately 210 miles, and irradiate the Earth with extremely high frequencies between 37.5 GHz and 42 GHz. This fleet will be in addition to a smaller SpaceX fleet of 4,425 satellites, already authorized earlier last year by the FCC, which will orbit the Earth at a height of approximately 750 miles and is set to bathe us in frequencies between 12 GHz and 30 GHz. The grand total of SpaceX satellites is thus projected to reach just under 12,000.
There are at present approximately 2,000 fully functioning satellites orbiting the Earth. Some beam down commercial GPS (or ‘SatNav’), some provide TV, some provide mobile phone services, and some bounce radar back and forth to produce images for meteorologists and military surveillance. The Earth is thus already comprehensively irradiated from outer space. But the new SpaceX fleets will constitute a massive increase in the number of satellites in the skies above us, and a correspondingly massive increase in the radiation reaching the Earth from them. The SpaceX satellite fleet is, however, just one of several that are due to be launched in the next few years, all serving the same purpose of providing global broadband services. Other companies, including Boeing, One Web and Spire Global are each launching their own smaller fleets, bringing the total number of projected new broadband satellites to around 20,000 – every one of them dedicated to irradiating the Earth at similar frequencies.
Why this sudden flurry of activity? The new satellite fleets are contributing to a concerted global effort to ‘upgrade’ the electromagnetic environment of the Earth. The upgrade is commonly referred to as 5G, or fifth generation wireless network. It has become customary in tech circles to talk about the introduction of 5G as involving the creation of a new global “electronic ecosystem.” It amounts to geo-engineering on a scale never before attempted. While this is being sold to the public as an enhancement of the quality of video streaming for media and entertainment, what is really driving it is the creation of the conditions within which electronic or “artificial” intelligence will be able to assume an ever-greater presence in our lives.
The introduction of 5G will also require hundreds of thousands of new mini mobile phone masts (also referred to as “micro-cells” or “base stations”) in urban centres throughout Australia, and literally millions of new masts in cities throughout the rest of the world, all emitting radiation at frequencies and at power levels far higher than those to which we are presently subjected. These new masts are much smaller than the masts we currently see beside highways and on top of buildings. They will be discreetly attached to the side of shops and offices or secured to lampposts. The 20,000 satellites are a necessary supplement to this land-based effort, for they will guarantee that rural areas, lakes, mountains, forests, oceans and wildernesses, where there are neither buildings nor lampposts, will all be incorporated into the new electronic infrastructure. Not one inch of the globe will be free of radiation.
Given the scale of the project, it is surprising how few people are aware of the enormity of what is now just beginning to unfold all around us. Very few people have even heard about the 20,000 new satellites that are due to transform the planet into a so-called “smart planet,” irradiating us night and day. In the national media, we do not hear voices questioning the wisdom, let alone the ethics, of geo-engineering a new global electromagnetic environment. Instead, there is a blithe acceptance that technology must continue to progress, and the presence in our lives of increasingly “smart” machines and gadgets that each year become cleverer and more capable is an inevitable part of this progress. And who doesn’t want progress? Almost everyone loves their sleek and seductively designed phones, iPads and virtual assistants, and regards them as an indispensable part of their lives.
The question we should ask is whether we also want increasingly intense exposure of the natural environment and all living creatures, including ourselves, to more and more electromagnetic radiation. Is it likely that this does not entail any adverse health consequences, as both government and industry claim? If the electromagnetic waves that connect our smartphones to the Internet travel through brick, stone and cement, then what happens when these same waves encounter our bodies? Be assured that they do not just bounce off us! They travel into the human body. The degree to which they are absorbed can be precisely measured in what is called the Specific Absorption Rate, expressed in Watts per kilogram of biological tissue. When we fill our houses with WiFi, we are irradiating our bodies continuously. When we hold a smartphone to our ear, electromagnetic waves irradiate our brains. Do we really believe this could be completely harmless?
Waves and Frequencies
At present, mobile phones, smartphones, tablets, WiFi and so on all operate at under 3 GHz in what is called the “microwave” region of the electromagnetic spectrum. If you could see and measure their wavelengths, you would find that they are many centimeters (or inches) long. A smartphone operating at 800 MHz, for example, sends and receives signals with wavelengths of 37.5 centimeters (just under 15 inches). Operating at 1.9 GHz, the wavelengths are 16 centimeters (just over 6 inches). WiFi uses the 2.4 GHz frequency band with 12 centimeter wavelengths (just under 5 inches long).
The introduction of 5G will entail the use of considerably higher frequencies than these, with correspondingly shorter wavelengths. Above 30 GHz, wavelengths are just millimeters rather than centimeters long. The millimeter waveband (from 30 GHz to 300 GHz) is referred to as Extremely High Frequency, and its wavelengths are between 10 millimeters and 1 millimeter in length.3 Up to the present time, Extremely High Frequency electromagnetic radiation has not been widely propagated, and its introduction marks a significant step change in the kind of electromagnetic energy that will become present in the natural environment.
The reason why millimeter waves are to be used for 5G is that much larger bands of spectrum are available in the Extremely High Frequencies than at lower frequencies. This means that there can be much broader “bandwidth.” Broader bandwidth means that larger quantities of data can be transferred and the speed of transfer of the data will be significantly faster. One of the effects of this is that it reduces what is called “latency,” or time-lag, in the system, improving the quality of video streaming. But in so doing, it also enables a greater seamlessness between the data accessible from virtual sources and our perceptions of objects in the real world, as is required, for example, in Augmented Reality applications. Greater seamlessness means that we more effortlessly inhabit the natural and the electronic worlds as if they were a single reality.
One of the technical problems of using frequencies in the millimeter region of the spectrum is that because the waves carrying the data are so tiny, being only millimeters long, they are less able to pass through physical barriers, like walls and trees, than are the longer waves of lower frequencies. This is why it is necessary to have so many more new “micro-cells” or “base stations.” They will need to be spaced at 100 meters apart in cities because beyond this distance their signals weaken and are therefore less able to penetrate buildings and connect with the devices inside. As well as being more closely spaced, the 5G micro-cells will operate at much higher power than current phone masts in order to ensure that the signals are sufficiently strong.
Because the wavelengths are so much smaller, the antennas transmitting and receiving them will also be much smaller than those of current phone masts and electronic devices. A single 5G transmitter/receiver will have a large number of tiny antennas, grouped together in one unit. An array of just over a thousand such antennas measures only four square inches, so will easily fit into a small base station on a lamppost, while the smartphone in your pocket will probably have sixteen.
Both 5G satellites and 5G land-based masts will use a system called the “phased array.” In phased array, groups of antennas are coordinated to radiate pulses in a specific direction and in a specified time sequence. This allows a concentrated beam of radio waves to be exactly aimed at designated targets, to enable signals to be sent or received. Because the beams are concentrated in this way, this adds to their power, which means they are able more easily to penetrate buildings. But it also means that any living creature that gets in the way of such a concentrated beam will be subjected to a powerful dose of extremely high frequency radiant electricity.
A study published earlier this year demonstrated that certain insects, because of their small body-size, are particularly vulnerable to the millimeter waves of the higher frequencies to be utilized by 5G.5 Other studies have shown that bacteria and plants are vulnerable, and so also (as one might expect) are the skin and the eyes of animals including, of course, human beings.6
As well as its ability to concentrate power in focused beams, phased array technology has a further complicating factor. Either side of the main beam, the time intervals between the pulses are different from the time intervals between those of the main beam, but they may overlap each other in such a way as to produce extremely rapid changes in the electromagnetic field. This can have a particularly detrimental effect on living organisms, because instead of the radiation decaying when it is absorbed into living tissue, it can be re-radiated within the body. The moving charges streaming into the body effectively become antennas that re-radiate the electromagnetic field and send it deeper into the organism. These re-radiated waves are known as Brillouin precursors, named after the French physicist Leon Brillouin, who first described them in 1914. Research suggests that they can have a significant and highly detrimental impact on living cells.8
The UN-reassuring Assurances of Government and Industry
The government body charged with advising on the health effects of electromagnetic radiation, the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), seeks to reassure us that there is no established evidence that Radio Frequency radiation (which radio, television, mobile phones, smartphones and 5G all use) has any adverse health effects on either adults or children.9 ARPANSA’s advice is largely based on findings derived from the supposedly independent AGNIR (Advisory Group on Non-Ionising Radiation), which advises the UK Health Department.10 AGNIR’s report, published in 2012, on the safety of Radio Frequency radiation stated that there was a lack of “convincing” and “conclusive” evidence for any adverse health effects. It was like giving a blank cheque to the telecommunications industry to move into the higher frequencies without any heed for the consequences.11
