DOHA: The United Nations Telecommunications Agency reported on Sunday that only a third of people in the world’s poorest countries have access to the Internet, but that low-orbiting satellites could provide newfound hope to millions, particularly in rural areas of Africa.
Tech titans like Microsoft have promised to help underserved communities “leapfrog” into the modern Internet age by funding the deployment of thousands of next-generation satellite transmitters.
According to the International Telecommunication Union, only 36% of the 1.25 billion people residing in the world’s 46 poorest countries have access to a computer with an Internet connection. In contrast, in the European Union, over 90% of the population has access.
The International Telecommunication Union criticized the “staggering international connectivity gap” that had grown over the previous decade.
UN Secretary General Antonio Guterres told the leaders of the Least Developed Countries at a summit in Doha, “you are being left behind in the digital revolution,” highlighting a major complaint at the summit.
Some African countries, such as the Democratic Republic of the Congo, suffer from a severe lack of access to the internet, with only about a quarter of the country’s nearly 100 million people having access to the web.
Major cities in the DRC, such as Kinshasa, have easy Internet access, but vast swaths of land that have been fought over by rival rebel groups for more than two decades are digital deserts.
Doha summit tech experts promised rapid change and a boost to African hopes with the launch of thousands of Low-Earth-Orbit satellites.
Microsoft’s plan to provide Internet access to 100 million Africans by 2025, as outlined before the summit, will rely heavily on satellite coverage.
In December, Microsoft made a commitment to bring Windows 10 to 5 million people in Africa, and just last week, they upped that number to 20 million.
Viasat is one of the companies launching satellite constellations into space to compete with terrestrial fiber broadband, and it will provide service to the first five million customers.
Space X and Starlink, both owned by Elon Musk, are launching thousands of satellites to an altitude of 400 to 700 kilometers (250 to 430 miles) above Earth.
To AFP, Microsoft president Brad Smith admitted that he initially questioned whether or not the 20 million figure proposed by his team last year was realistic, but that he is now convinced it is possible.
The price of technology has dropped significantly and will continue to do so, he predicted. That’s why we can expand so rapidly to serve such a large population.
The African continent “has the opportunity to leapfrog other nations when it comes to regulatory structure for something like wireless communications,” he continued.
As an example, “we can reach much more people than we could with fixed line technologies five, ten, or fifteen years ago.”
The available bandwidth has been largely allocated for telecommunications and television in the more developed nations.
Unlike in the United States, “the spectrum isn’t being used in Africa, so it is available and the governments are moving faster to bring this connectivity to more people,” Smith said.
Internet access for an additional 20 million people in Africa is being made possible thanks to a partnership between Microsoft and telecoms expert Liquid Intelligent Technologies.
Smith declared, “we are bullish on what we believe digital technology can do for development” as he explained why his company was providing Internet access and digital skills training to thousands of Africans as a private sector alternative to “foreign aid.”
Although the private sector is “woefully under-developed and under-invested” in many LDC economies, Microsoft’s president admitted as much.
Although Liquid Intelligent is expanding its terrestrial fiber network across Africa (100,000 km; 62,000 miles), it is also making significant strides in the satellite sphere.
According to Nic Rudnick, the company’s deputy chief executive, “satellite is often the only technology or the most reliable technology for fast broadband that always works in hard-to-reach areas.”


You connect each effect's 9v and ground connections to each other then to the power jack/battery connector
bajaman wrote:You connect each effect's 9v and ground connections to each other then to the power jack/battery connector
I would prefer to isolate each stage by running a separate 100 ohm resistor to each effect from the + 9v supply socket or battery positive terminal and then drop a 220uf electrolytic(or larger if you prefer) from the circuit side of these resistors (2 electros required) to ground. By doing this you will decouple any signal voltage from travelling through the power supply rail between each effect and enhance operational stability by reducing or eliminating any intermodulation artifacts, particulary in the high frequency range. Make sure you connect the negative terminals of each electrolytic to ground.
bajaman wrote:Hello - is this clearer
Add a 100 ohm resistor from EACH effect's +ve supply rail to the + 9v supply socket or battery positive terminal and then add a 220uf polarised aluminium electrolytic capacitor from EACH circuit's +ve supply rail to ground (connect the -ve pins of the capacitors to ground). This is a very old "trick" known as supply rail decoupling and it works surprisingly well, particularly when running effects from a common power supply adaptor. Many good designers already use this method of decoupling in their products - a schematic helps to identify this.

This page is for realistic scientifically plausible slower-than-light communication. For unrealistic science-fictional faster-than-light communication see this page.
This deck contains communication gear, perhaps even with something like a Morse code key for use when radio interference becomes a problem (If this was a Metalunan ship, this is where you'd find the interociter).
Sometimes this deck is called a "radio shack", manned by a communication officer whose nickname is "Sparks." Communication officers are the ship's ears and mouth. They direct incoming messages to the proper departments and send outgoing messages in the proper format to the proper channels. Communication noise must be monitored and auxiliary channels used if required. All messages must be logged. Distress signals are sent to the watch officer, but never responded to without authorization. Responding binds the ship to render assistance, a decision reserved for the captain. The communication officer must also maintain the ship's transponder, which broadcasts the ship's ID.
The communication officer may also be responsible for encrypted communications, using the proper keys to encrypt and decrypt. If this is a military spacecraft, the comm officer is responsible for destroying the code book if the ship is captured by a hostile power. Hit the red "incinerate" button to keep the one-time pad and Captain Midnight secret decoder pin from falling into enemy hands. The safe containing the code book may be on the communications deck, but on some ships it is in the captain's cabin.
Communication will generally be by radio or laser.
A problem seldom seen in Terran based radio communication is time lag. Radio and all other electromagnetic radiation travels at c (the speed of light in a vacuum), which is 299,792,458 meters per second. For obvious reasons this is called one light-second.
The average distance between Terra and Luna is 1.282 light-seconds. This means if you are at Clavius moon base talking to Dr. Floyd on Terra, the delay between when you stop talking and Dr. Floyd starts will be a minimum of 2 × 1.282 = 2.563 seconds.
At their closest approach, the distance between Terra and Mars is about 78 million kilometers or 260 light seconds. This means the round-trip delay will be about 8.7 minutes! When NASA's Curiosity rover landed on Mars, the delay was about 13 minutes one-way, which was rather nerve-wracking. Driving the rover is also very tricky with such a huge delay factor.
Back in the 1900's, Amateur Radio (aka "ham radio") was very popular. Back in those days people didn't travel very much. But if you got your amateur radio license and a radio rig, you could talk with people between 30 and 100 kilometers away. Or even over 400 kilometers away if you link to a radio repeater station. It was sort of like a more powerful and regulated version of the CB radio used by truckers. Science fiction writers like Poul Anderson postulate that rock rat asteroid miners would also be avid ham radio operators. A miner at their claim would probably be located at an inconveniently large distance and large delta V from the closest neighbor. Ham radio is a cheap way to keep in touch, and pass news & gossip. You probably can get more range if you use Morse code instead of speech.
In the communication version of the Kzinti Lesson, note that long range laser communication gear can be used as short ranged laser weapons. In many of Larry Niven's "Known Space" stories comm lasers have been used as weapons, e.g., "There is a Tide" and "The Ethics of Madness."
Radiators are not the only thing spoiling the Polaris' sleek external lines. Roger Manning's radio needs large dish antennas. They might not be as large as the monsters on 2001's Discovery, but they won't be much smaller than the ones on the Apollo service module. It might also be a good idea to have landing radar on an outrigger or boom, so it won't be blinded by the exhaust. Both of these will be retracted during atmospheric re-entry, with the landing radar deployed when the air speed drops low enough so it won't be ripped off.
Range is how far you can transmit a message. Major factors are:
- Power in the signal, including loss due to inverse-square law
- Sensitivity of the receiver
- Noise in the signal, including electromagnetic interference from natural and artificial sources
By "bandwidth", I mean in the computing sense: how many bits per second of digital information can be trasmitted. The other sense (signal bandwidth) is width between the upper and lower set of frequencies used.
As an example, using old 1977 technology the Voyager space probes use S Band (2 to 4 GHz) communications with 3.7 meter high-gain antennas. As the ranged to Earth increased, the bit-per-second rate decreased due to the inverse-square law. Using the 62 m Deep Space Network dishes as receivers, at Jupiter it was 115 kBits/sec. At Saturn it was 57 kBits/sec. It went rapidly downhill from there.
As far as signal bandwidth goes, voice transmission typically takes 2400 Hz, while Morse code takes only 100 to 150 Hz.
A final matter is that there is only so many radio frequencies to go around, so some authority has to be in charge of radio spectrum allocation.
Radio proper typically use the electromagnetic spectrum from 3 kHz to 300 GHz.
Laser communicators typically use visible, infrared, or ultraviolet frequencies. Currently the maximum range that laser communication has managed in the field is 24 million kilometers, but that will no doubt be improved by many orders of magnitude.
Some times masers are used in recievers in order to amplify weak radio signals.
Also read about the Interplanetary Internet.
Sometimes solar storms or enemy jamming might fill the communication lines with static. If it is real bad, one might have to revert to good old Morse code. The dot and dash symbols can punch through interference much easier than the spoken word. Even present day naval vessels can send Morse code by Signal Lamps, when the enemy might overhear a radio message.
By its nature, Morse code is sent over the radio by Amplitude Modulation (AM), not Frequency Modulation (FM) or other kind of modulation. Radio Morse code requires less signal bandwidth (100 to 150 Hz for typical speeds in the 20 to 40 word per minute range) compared to voice (2400 Hz), though it has a lower data rate.
Morse code is usually received as a medium-pitched audio tone (600–1000 Hz), so transmissions are easier to copy than voice through the noise on congested frequencies (too many conversations taking place on the same band), and it can be used in very high noise / low signal environments (loud static and faint voice, never a happy situation). The transmitted power is concentrated into a limited bandwidth so narrow receiver filters can be used to suppress interference from adjacent frequencies (narrowing the opening that static and competing conversations can leak through).
The narrow signal bandwidth also takes advantage of the natural aural selectivity of the human brain, further enhancing weak signal readability (translation: it is easier to hear a dot or dash than it is to decipher somebody slurring their words). The signal can be weak if the sender is distant, has low amounts of power available for the radio, or both. Very well could be good news for castaways in a wrecked spacecraft in the back of the beyond. In fact the required bandwidth can be reduced and the signal range increased by simply drastically slowing down the word per minute rate. Dave Hinerman (WD8CIV) told me about some hams who experimented with computer generated Morse code with the dots lasting ten seconds and the dashes lasting 30. They were trying to see what was the least amount of power needed to transmit a receivable decodable signal.
In addition, a Morse code signal is easier to jury-rig than a full two-way radio (for instance: by tapping two wire together). Which could come in handy for an interplanetary spy trying to transmit information using the equipment at hand before the bad guys burn open the hatch with their laser pistols. Or by survivors of a drastic shipboard accident that destroys the communication equipment. Or if Our Hero is in a holding cell of the evil villain's lair, covert communication would be possible with prisoners in other cells by tapping on the walls (though actually prisoners would want to use a Tap Code because it is hard to tap a "dash" sound). Or sending a message by turning on and off a flashlight or using a mirror to flash sunlight at the intended message recipient (in olden days this was the mechanism used by heliographs).
Skilled telegraphers can comprehend ("copy") Morse code signals at rates in excess of 40 words per minute. Top sending speed by experts might be around 75 to 100 words per minute. Individual telegraphers might use slightly longer or shorter dashes or gaps, perhaps only for particular characters. This is called the telegrapher's fist, and other telegraphers can recognize specific individuals by it alone. A good telegrapher who sends clearly and is easy to copy is said to have a "good fist". A "poor fist" is a characteristic of sloppy or hard to copy Morse code.
There are three main types of Morse code "keys" (devices used by telegraphers to tap out the dot-dash Morse code signals). They are Straight Keys, Semiautomatic Keys and Iambic Paddles. Improvised keys generally take the form of two wires that the telegrapher taps together.
My dear departed maternal grandfather used one of those as a radio HAM. I tried to use it but was never very good at it.
My dear departed maternal grandfather rigged up one of these for a friend of his who had a disability in his arms. My grandfather bolted the paddles under the table and crafted a long lever his friend could control with a knee.
So in times of imperfect reception one can fall back on Morse Code. But even with perfect reception, some spoken items are hard to distinguish. The letters "T" and "D" for instance. Misunderstood words and letters can be catastrophic, especially in a military situation. To avoid this the NATO phonetic alphabet is commonly used. Also useful are military "brevity words."
Another useful source is the International Code of Signals. These are a set of international code signs and words that do not depend upon the two people communicating to share a language in common. They include multicolored flags, semaphore, blinking lights, Morse code, and radio. For instance, AJ means "I have had a serious nuclear accident and you should approach with caution" and EO means "I am unable to locate vessel/aircraft in distress because of poor visibility". Those signals can be understood even if the sender only speaks Mandarin Chinese and the receiver only speaks Czechoslovakian. Refer to the manual found here.

Lots of communication will have to be encrypted for security reasons, especially if a crew member is doing some online banking. For non-military purposes, a useful innovation is Public-Key Cryptography. It allows two valuable functions:
 Encrypting Messages
Ordinary encryption allows specific persons to send you a message that only you can read. Problem is that the encryption key they use is also the decryption key. Which means anybody with the key can read the encrypted message, not just you.
There is also a problem when you try distributing the key to the specific people you want. If an evil spy intercepts the key, they can read any message sent to you. Worse: the evil spy might swipe the key and subsitute their own secret key. Sending the key safely to your friends is really hard.
With public key encryption this is not a problem. The encryption key is NOT also the decryption key. You can broadcast the encryption key far and wide with no attempt at security, it won't hurt anything. This makes distributing the encryption key easy, just post it on the internet. It doesn't matter if evil spy obtains it, they cannot use to decrypt your messages.
 Digital Signature
When it comes to digital signature, the trouble with ordinary encryption is that it cannot do it at all. Public-key encryption can.
Digital signature is an extra bit of encoded message you attach to a cleartext message. It "gives a recipient reason to believe that the message was created by a known sender, that the sender cannot deny having sent the message (authentication and non-repudiation), and that the message was not altered in transit (integrity)." Better than a pen-and-ink signature on a contract, since a digital signature sort of rots away if somebody changes the contract.
How Does It Work?
If you only wanted to know why public-key encryption is so popular, you can stop reading now. What follows is the esoteric inner workings of the scheme.
Encryption is taking a message (the "plaintext") and scrambling it into an unreadable mess (the "cyphertext") so that the Wrong People cannot read it. The Right People can unscramble the message back into plaintext and read the message. It is much like two last-century children sending messages using their Captain Midnight secret decoder badges ("Be sure to drink your Ovaltine").
Old fashion garden-variety encryption uses what is called a Symmetric-key algorithm. The sender takes the plaintext plus an encryption key (in the form of a huge number with many digits) and feeds both into the encryption algorithm (meaning you put both into your encryption sofware or smartphone app). It spits out the cyphertext.
The cyphertext is sent to the recipient. They feed the cyphertext and the encryption key to their encryption algorithm and the cleartext pops out. The Wrong People cannot intercept the message (unless they manage to crack the encryption or swipe the encryption key).
What makes this "symmetric-key" is the fact that both sender and recipient are using the same key.
Public-Key Cryptography is different. There are two keys: A and B. A message encrypted with key A can be unencrypted with key B and a message encrypted with key B can be decrypted with key A. And a message encrypted with key A cannot be decrypted with key A. This is also called an asymmetric-key algorithm.
The two keys are generated by the user using a key-pair generating software, by feeding the software a huge random number.
How do you use it?
The user calls key A the "public key", and broadcasts it far and wide. Key B is the "private key", and the user keeps it a deep dark secret.
For  encrypting messages, anybody can use your public key to encrypt a secret message intended just for you. The message can only be decrypted with your private key, which presumably only you know. Thus the sender is reasonably sure you are the only one who can read the secret message.
In the example at right, Bob sends the secret message "Hello Alice!", encrypting it with Alice's public key. Only Alice can decrypt it by using her private key.
For  digital signature, it is a bit more complicated. To do it simplistically, you would "sign" a document (say, a contract) by encrypting the document with your private key. Anybody else in the universe can use your public key to decrypt the contract. The fact that your public key worked is proof that the document was encrypted with your private key, which presumably only you have. Thus it is proof you "signed" the document.
In the example at right, Alice digitally signs the contract "I will pay $500" by encrypting it with Alice's private key. Bob can verify Alice's signature since the message decrypts with Alice's public key.
In practice, since encrypting a huge document can take an annoyingly large amount of computing time, digital signature generally use a cryptographic hash (message digest) of the document. The hash is encrypted with the private key instead of the entire document. The encrypted hash is transmitted along with the plaintext document. To verify that you digitally signed the document a person has to:
- Decrypt the encrypted hash with your public key
- Generate a hash of the plaintext document
- If the two hashes are identical, the digital signature is valid
Clever readers will have spotted the flaw in the system: How do you know the public key is really associated with the person? Some disaffected young person living in their mother's basement can claim they are Stephen Hawking and distribute a public key. How is anybody going to be sure that any given public key actually comes from who claims it?
What is needed is a Public key infrastructure. Among other things, the infrastructure binds a person with their public key, that is, they ensure that Stephen Hawking is actually associated with Stephen Hawking's public key and not some disaffected young person living in their mother's basement. This is done with a Certificate Authority (which is also a Trusted third party).
A person who has generated a public and private key makes an application to the certificate authority. The authority does some checking to ensure that person is actually who they say they are. Usually this is via some simplistic domain validation but the validation becomes more stringent as the amount of money at stake increases.
Assuming the person passes the check, the certificate authority issues a public key certificate, which is a fancy way of saying the CA broadcasts the public key and assures everybody that it actually belongs to the person. Of course the public key certificate is digitally signed with the CA's private key.
An Automatic Identification System (AIS) is a radio system on a vehicle that continually broadcasts the vehicle's unique ID, position, course, speed, and any other vital navigational information. Currently these are found mainly on naval vessels.
A Transponder is a radio system on a vehicle that responds to a radio interrogation message with a radio reply containing the information. Interrogations such as "identify yourself", "what is your altitude?" etc. If there are no interrogations, the transponder is silent. Currently these are found mainly on aircraft. "Transponder" is short for "transmitter-responder".
AIS and Transponders are the responsibility of the ship's communication officer. Which is why this section is in the "Communication Deck" page.
In the Traveller role playing game, by law civilian starships are equipped with something they call a transponder, but which acts more like an AIS (it is constantly broadcasting). In Traveller it is illegal for a civilian starship to turn off its transponder, unless there are mitigating circumstances. Which usually means a fear of pirate corsairs using your transponder signal to home in on you.
Pirate ships will need illegal "variable transponders" that can be set to broadcast fake identities, in order to lull the suspicions of both victims and police.


Vocabulary Growth in Speech Recognition
People have been working on large vocabulary continuous speech recognition (LVCSR) since the 1980's. As computers became more powerful and the speech recognition technology advanced, the meaning of "large vocabulary" has changed. In the early days, a vocabulary of one thousand words was considered large. Now, vocabularies of one million tokens is the new norm.
To analyze the trend, I collected 32 publications where the authors built a LVCSR system and recorded the size of the recognizer vocabulary. These were published between 1988 and 2015.
The trend is for the size of the speech recognition vocabulary to double roughly every four years.

Air Force Uses Airborne Lasers to Create High-Speed Data Links
Researchers have tested the laser links at distances of almost 22 miles during flight
Manned Air Force jets and drones could soon send high quality video and audio by using ultra-high bandwidth lasers, transmitting critical battlefield data faster than ever. The Air Force Office of Scientific Research has conducted experiments that transmit data without interference across almost 22 miles, both in the air and on the ground.
Transmitting data through laser optics has typically suffered from atmospheric turbulence or temperature distortions. But the Air Force researchers used adaptive optics — a process similar to how powerful telescopes compensate for atmospheric distortions to create sharp images of distant stars.
The Register notes that a laser beam could carry encrypted information in the same way that fiber optics carry such data. Sensitive data is converted to individual photon packets of light, so that any attempts to intercept the transmission would change the data and alert communications personnel.
“If we can now put one link on the ground and one on a demo aircraft, it wouldn’t take much to apply the technology to operational aircraft for the Air Force,” said David Hughes of the Air Force Research Laboratory in New York.
For now, Hughes and his team have teamed up with AOptix Technologies to conduct more flight tests and demonstrate this capability over greater distances. That could pay off with an even more interconnected battlefield that allows drones to send back intelligence data at higher speeds.
In any case, it’s also a nice Air Force demonstration of lasers beyond burning things.

Manufacturing – “Smart Factory”
Through rapid developments in IoT – dynamic and ever-evolving environments which generate high-volume streams of heterogeneous data – the whole manufacturing industry is currently overthrowing traditional production, quality control and surveillance practices.
In such environments The DeepEyes algorithm on standard cameras (as data capturing device, sensor) can be used to make working environments smarter, more precise and more secure.
Various application areas are possible:
The DeepEyes technology can give robots the ability to “detect” humans who enter their operation space on a very fine-tuned basis. This ensures human safety and at the same time reduces interruption times in the working process.
Montoring if individuals are not in a physical state to operate accident-prone machines, can be recognized (a-normal movements, gestures etc.)
Monitoring if individuals wear security apparel.
With DeepEyes technology both manual and chemical processes can be monitored in order to ensure that quality standards are met. With two 1080p cameras and our software we can detect anomalies of 0.01 mm in 3D at 1 m distance.
- Automated monitoring of gestures and movements of workers in meat/fish processing thus ensuring that quality standards are being met.
- Process surveillance in the production of synthetics or food (brewing, baking etc. )
The DeepEyes technology DeepPose can identify body movements and reflect these on the screen with the use of a standard video camera. This represents a huge advance in game development and also allows to enhance existing game offerings.
The scope of the DeepEyes technology is much wider than the usual Kinect and Leap Motion technology, as it does not require additional expensive equipment. A simple webcam or smartphone is all it takes.
DeepPose uses standard hardware, is very precise in detecting motion and distance, easy to use and there is no need for an internet Connection.
The DeepEyes algorithm is undemanding in operation. Processing a video in 720p / 30fps only consumes 10% of CPU (i5 2520m) and 50 MB of RAM. Optionally, the system can be configured to accompany the human hand, its fingers, or to recognize the posture of a person.

OB Fire-Rescue leading effort for water safety phone alert system
Orange Beach Fire-Rescue is coordinating with Gulf Shores Fire-Rescue and the Baldwin County Emergency Management Agency to create a cell phone beach safety alert system that could be a game changer for water safety awareness on the Alabama Gulf Coast.
The system would provide a link to visitors’ cell phones through the county’s Everbridge mass notification system. Baldwin County already uses the system’s software for its “AlertBaldwin” program that notifies citizens about mostly weather related emergency situations.
OB Fire Chief Mike Kimmerling (pictured) said getting people to sign up for the service would require coordination with local businesses such as short term rental companies to alert visitors that they can text a keyword to Everbridge’s number, 888-777, to receive notifications when red flags are flying on local beaches.
“There’s going to have to be some collaboration with businesses, with municipalities and with billboards. We could get waterproof fliers to hand out at all the condos that has beach safety flag information. The info is something we could print on the bottom,” said Kimmerling.
Two men, including Baldwin County Sheriff’s Deputy Bill Smith, drowned in rough surf in Fort Morgan this month.
“We need to be looking at every way we can to help educate people to have them have a good time and still be safe,” said Kimmerling.

Remote Power Systems
Photovoltaic solar power systems are ideally suited to provide power in almost any situation where the grid is either unavailable or not desired, from simple water pumping systems, remote telemetry and communication systems right through to complete households and stations, anything needing electricity can be powered by the sun using photovoltaic solar power systems.
In some situations it may be beneficial to combine more than one energy source, into a hybrid system. Hybrid systems are generally used when the power requirements are quite high, such as for a household or worksite and can include any mix of solar power, wind power, hydro power, diesel (or other fossil powered) generators and / or virtually any other available source of electricity.
Household Remote Power Systems
Typical household 'stand alone' power systems (SAPS) use solar as the primary power source, often with a diesel genset to provide backup in case of extended poor weather or short term increases in electricity requirements.
Remote power systems are individually designed by our photovoltaic engineers to meet the specific requirements of the client and specific details of the site. The size of the solar arrays and battery banks will depend largely on how much energy the household uses and the system location. The more power consumption, the larger the solar power system will need to be. Systems can be single or three phase and can be as large as required. Household scale remote power systems for a generally cost between $20,000 and $50,000 and will offer decades of reliable energy from the sun.
Other generators such as wind or micro hydro can also be integrated to the system where available.
Contact Autonomous Energy to talk to one of our engineers about what system would be best for you.
Industrial Remote Power
Solar power is often the cheapest and most effective way to power a range of remote sites from small telemetry systems or traffic signals right up to telecommunications plant or mine site accomodation. Solar power systems can be designed to provide DC or AC power or both.
Some typical uses for remote solar power systems include:
- Water pumping
- Remote accomodation
- Street lighting
- Advertisement illumination
- Telecommunications stations
- Island power
Autonomous Energy provides both engineering services as well as turn key solutions. Please contact Autonomous Energy for more information or for a proposal to power your project.


What are ground wave, sky wave and Space waves
Wave which glides over the surface of the earth is called ground wave and the mode of propagation is called as surface wave propagation.
To radiate signals with high frequency, the antennas should have a size comparable to the wavelength λ of the signal on or very near to the ground. In antennas have large physical based vertical towers current in the ground. In standard AM broadcast, ground-based vertical towers are generally used as transmitting antennas.
A wave induces current in the ground over which it passes and it is attenuated as a result of absorption of energy by earth. The attenuation of surface wave increases very rapidly with increase in frequency. The maximum range of coverage depends on the transmitted power and frequency. Ground waves will propagate long distance over sea water due to its high conductivity.
Long distance communication between two points on earth can be achieved by the ionospheric reflection of radio waves are called sky waves.
These waves have a frequency range from a few MHz up to about 30 MHz. The mode of propagation is called sky wave propagation.
The ionospheric layer acts as a reflector for a certain range of frequencies (3 to 30 MHz). Electromagnetic waves of frequencies higher than 30 MHz penetrate the ionosphere and escape. The phenomenon of bending of electromagnetic waves is so that they are diverted towards the earth which is similar to a total internal reflection in optics. Above 200 MHz ionosphere becomes completely transparent i.e., the waves of that order cannot be reflected back to earth.
These waves used in shortwave broadcast services.
Space wave communication
The waves which travel in a straight line from transmitting antenna to the receiving antenna are space waves. Communication done by using space waves is known as space wave communication.
At frequencies about 40 MHz communication is limited to line of sight paths. At these frequencies, the antennas are relatively smaller and can be placed at heights of many wavelengths above the ground.
Because of the line-of-sight nature of propagation, direct waves are blocked at some point by the curvature of the earth. If the signal is to be received beyond the horizon, then the receiving antenna must be high enough to intercept the line of sight waves.

The Quantum Random Number Generator (QRNG) chip, in theory, provides data encryption at such a high level that a smartphone cannot be hacked even with a targeted attack, let alone an ordinary mass hacker action.
Samsung, together with the largest South Korean telecom operator SK Telekom, presented the world’s first smartphone equipped with a quantum random number generator. The gadget called Galaxy A Quantum has a quantum chip Quantum Random Number Generator (QRNG), which provides data encryption at such a high level that the smartphone can not be cracked even with a targeted attack, not to mention the usual mass actions of hackers.
This chip is capable of creating truly random and unpredictable encryption keys that cannot be picked up for hacking. Unlike conventional information encryption methods based solely on mathematical formulas, physics is also involved in quantum encryption. It uses a light-emitting diode that emits a random photon and a CMOS sensor that reads it. And all this is placed in a tiny chip with dimensions of only 2.5 x 2.5 mm.
So, the Galaxy A Quantum is the most usual Galaxy A71 5G with the Exynos 980 processor.

This property situated on a new rural development in Sussex benefitted from beautiful architecture, with large open plan spaces and a modern finish. However, given the price point, the lighting, heating, and home control systems fell considerably short of the clients expectations through a lack of modern technology, connectivity options, and most importantly controllability.
By replacing the light switches with Crestron wireless keypads, and introducing Honeywell’s wireless Evohome heating control system, a straight forward retro-fit installation using the exisiting mechanical and electrical infrastucture within the property, overlaid with the intouch user interface, has provided a substantially enhanced system that now gives the client intuitive control over ligthing, heating, powered blinds and Sonos wireless audio.
Taking things to the next level, we included an Amazon Echo unit that gives the home owner the ability to control all of these functions with simple voice commands. For example, by saying ‘Alexa, tell Crestron it’s time for bed’, the blinds drop, the lights slowly dim until off, the music stops playing and the heating drops by 2 degrees. Our ability to seemless integrate so many functions into a single, simple command has created a more convenient and efficient living environment in this property.

Epofat Tunnel Guard (ETnlG) is a stand-alone system designed to detect
any human moving within a tunnel made of steel reinforced concrete or
other materials. The system uses a single vertically mounted sensor
housed in an eight inch diameter protective durable PVC pipe that can be
lowered down a bore-hole next to the SRC tunnel. The sensor is then
connected to and powered from a surface control unit. Any human passing
by the sensor within the tunnel will immediately be detected and an
alarm indicated at the surface control unit. As for all Ralen Epofat
products the technology employed is harmless for operators and detected
individuals alike. The system will always detect the presence of any
living human being but will ignore any animal signature such as rats,
dogs, cats etc.
The sensor is operated from a control workstation situated on the surface in an appropriate booth or room. Alternatively all information can be relayed to another more suitable location for command and control purposes. All data from the sensor are stored centrally.

Sometimes I wonder if technology is really all it’s cracked up to be. At times (probably most of the time) it can be a wonderful thing. There are so many pieces of technology that make life easier, and make it easier for us to share our lives with others. There are times, when I do something that wouldn’t have ever been possible before with out it.
But at other times, I wonder. Yeah it’s great, but when it’s not working correctly, it can really be a pain. For instance: we use a VoIP phone. And when it’s working correctly it’s great. It’s cheap, and gives us more features. But when it’s not working it’s a pain. The internet is another example, when it’s up and the network is functioning properly, it’s great, when it’s not, it’s a pain.
Today, the network wasn’t working when we got back from the park, so I had to spent the next 3 or 4 hours getting it back up and working. It’s all working now, and I’m obviously online, but it was a royal pain to go through the process to figure out what was wrong.
Technology also has other issues. For instance, since we use a VoIP phone, it makes it more challenging to have phones throughout the house. So we either had to buy a more expensive phone with more extensions, or I had to figure out how to run the phone into the wiring in the house. I did that, but then there was interference from the phone service in the house. So, I had to disconnect the phone service outside the house. Now we have the phone running through the wiring in the house, which is nice. However, I’m forcing this new technology to fit into the mold of a technology that is becoming extinct. Which means at some point it will be extinct and we’ll have to buy something else to replace it.
I’m online, but thinking about not being so.
