Beamcaster: alternativa al Wifi basata su raggi infrarosso

Qualche giorno fa vi ho dato un'informazione che si è rilevata non corretta.

Dopo accertamento fatto presso l'azienda produttrice,  scopro che il reclamizzato Beamcaster non funziona tramite raggi a luce LED ma a radiazione infra rosso.

Ricordo che questa tecnologia permette di trasmettere il segnale digitale, in una stanza (open space) tramite un 'trasmettitore' da fissare al soffitto che dialoga con fino a 8 riceventi che sono i vari 'device' , quali personal computer, stampante, etc.

Loro fanno riferimento ad una approvazione emessa della americana FDA (ho chiesto copia ) .

Io non ho trovato articoli scientifici su ricerche di effetti delle radiazione infrarosso ai sistemi cellulari od altro. Faccio un approfondimento .

Per il momento mi sembra una alternativa al Wifi  tecnicamente valida . Vedere qui

Sentenza tedesca d'appello che riconosce la elettrosensibilità come malattia professionale

Prima sentenza confermata in appello di un tribunale tedesco di riconoscimento di elettrosensibilità .

E' una  causa avviata da un ex-militare radarista tedesco : è stata riconosciuta come malattia professionale.

Qui sotto è riportato il lungo iter, iniziato con primi sintomi evidenziati nel 1973 , nel 1994 lo Stato Federale ha rigettato la richiesta di riconoscimento della malattia, acquisita a causa di servizio ; è andato in pensione nel 1994.

Ha iniziato la causa contro lo Stato Federale Tedesco. La controparte ha eccepito che EMF sotto i valori limite riportati da WHO/OMS, ICNIRP e Agenzia tedesca per le radiazioni, non sono dannose.   Egli ha portato alla corte gli studi e la testimonianza di Drr Karl Hecht e Lebrecht von  Klitzing .
La corte ha incaricato un  esperto nel 2005 che ha dato ragione allo Stato.
Dopo altre testimonianze tecniche la corte ha incaricato un altro esperto  che nel 2008 ha dato ragione all'ex militare.

Ovviamente lo Stato ha fatti ricorso alla Corte d'Appello (?) che ha incaricato altro esperto, che ha detto che esiste la relazione tra malattia e fonte di radiazione.
Quindi sentenza definitiva.

EHS of a former German Army Radar-mechanic acknowledged as occupational disease by the court of appeal for administrative litigation in german state Schleswig-Holstein (Schleswig-Holsteinisches Oberverwaltungsgericht)
3 LB 21/11, September 13, 2012
The plaintiff worked for the geman army (Bundeswehr) from 1970 to 1992 as a mechanic for Radarsystems. While working he was exposed to ionizing and non-ionizing radiation. Since 1973 the plaintiff suffered from inflammation, infectious diseases and palpitations. From 1976 he also suffered from agitation, sleep disorders, fatigue, lack of concentration and extreme forgetfulness, extreme headaches, disorder of the immune system, food allergies and other allergic symptoms, non-functioning eyesight, sweats, exhaustion until midth of the 90ies.
The plaintiff was diagnosed with EHS and treated in two clinics in 1993. In 1994 the Federal Republic of Germany as his employer rejected to acknowledge his illness as an occupational disease claiming there is no proof that his symptoms are caused by the exposure. In 1994, the plaintiff was pensioned off.
The plaintiff filed a law-suit against the Federal Republic as his former employer to the court for administrative litigation in Schleswig to get this acknowledgement. He gave the court several reports of experts who examined his or other Radar-Mechanics conditions. As the court granted the plaintiff´s suit the defendant filed an appeal to the higher court, arguing that committees and experts- the WHO, the ICNIRP and the german committee for the protection of radiation (Strahlenschutzkommission – SSK) are of the opinion that EMF-exposure below standards does not cause any physical harm.
The plaintiff sent the court Prof. em. Prof. Dr. Dr. med. Karl Hecht´s study from 2001 on „Effects of EMF“ as well as a report by medicine physicist Dr. rer nat Lebrecht von Klitzing on the biological effects of pulsed high frequency waves below standards as well as a synopsis by Prof. Hecht from 2005 that explained that the majority of personnel exposed to radiation suffered from the symptoms of what is called the „microwave syndrom“. The court appointed another expert who reported in 2005 and 2006 that the plaintiff´s symptoms are not caused by ionizing or non-ionizing radiation or a combination of both. After hearing several other expert witnesses – among them Prof. em. Prof. Dr. Dr. Karl Hecht and Dr. rer. nat. Lebrecht von Klitzing – the court appointed another expert and – after another hearing – obliged the defendant to acknowledge the plaintiffs request in a verdict from August 20th, 2008.
On appeal, the highest federal court in administrative matters (Bundesverwaltungsgericht) declared that the decision violated federal law as the court had not taken enough efforts to research the facts. The court of appeal than appointed a third expert who stated that it was possible to proof the causation of the plaintiff´s exposure and his disease.
The court ruled again in favor of the plaintiff and also ruled that another appeal is not permitted. The defendant´s complaint against this to the highest federal court was not successful. In consequence, the acknowledgement is now legally binding.

Hypothesis on how to measure electromagnetic

Electromagnetic hypersensitivity (EHS) is an ill-defined term to describe the fact that people who
experience health symptoms in the vicinity of electromagnetic fields (EMFs) regard them as
causal for their complaints. Up to now most scientists assume a psychological cause for the
suffering of electromagnetic hypersensitive individuals. This paper addresses reasons why most
provocation studies could not find any association between EMF exposure and EHS and presents
a hypothesis on diagnosis and differentiation of this condition. Simultaneous recordings of heart
rate variability, microcirculation and electric skin potentials are used for classification of EHS.
Thus, it could be possible to distinguish “genuine” electromagnetic hypersensitive individuals
from those who suffer from other conditions.

Il Ministro dell'ambiente tedesco lancia segnali di allarme per il Wifi

Ripreso da un articolo su stampa inglese, si riporta come il Ministero dell'ambiente tedesco lanci segnali di precauzione alla popolazione di ridurre il più possibile l'uso di sistemi wireless ed invece di utilizzare connessioni via cavo. Inoltre si raccomanda di dare ampia informazione alla popolazione.

Il governo inglese si è di conseguenza parimente allarmato.

e quello italiano ?!

Incontro estivo in una zona libera da EMF, in Francia

è stata organizzata da associazioni ambientaliste francesi, con la partecipazione sia della deputata europea Michel Rivasi che dal Prof Belpomme una settimana di incontri sulle tematiche relative alla elettrosensibilità in una area delle Alpi francesi situata a 300 ca  Km da Torino .

Il luogo di incontro è scelto in quanto non ci sono assolutamente segnali e neanche la corrente elettrica. Ci sono anche camere. 
Vicino c'è una cittadina con strutture ricettive più normali, anche se distanti da antenne.

Può essere una opportunità di scambio e magari per riprendere discorsi che mi pare abbandonati di propos

Un bar canadese Wifi-free !

E' stato aperto in Canada un bar  in cui so è voluto creare un ambiente dove nessun segnale telefonico e wifi potesse entrare :   la scelta è stata più di tipo sociale che sanitario. 
Provare e creare un piccolo pezzo di 'disconnected city' !

Dopo alcuni tentativi di mettere alle pareti fogli di alluminio (insufficiente) è stata creata, allo interno del locale, una vera gabbia di Faraday.

Chissà se questo esempio farà il giro del mondo ?

Viene richiesto un contributo per sostenere la ricerca indipendente (Prof Hardell)

C'è la possibilità di dare un contributo economico alle attività di ricerca del Prof  Hardell.

vedere qui

Ricordo che grazie alle ricerche di Hardell si è arrivati alla classificazione 2B dello IARC per i CEM. Infatti i suoi studi e le sue conclusioni (secondo le quali si deve passare ad una classificazione di 'probabile cancerogeni')  sono sotto attacco da tutta la 'ricerca' non libera di tutto il Mondo.

Quindi immaginiamo come questo signore ed il suo staff possano lavorare, con quale libertà, finanziamenti pubblici, ...

E' doveroso per tutte le persone interessate ai suoi studi dare  il proprio  contributo.

Ho chiesto se questi contributi possono essere fiscalmente deducibili per le nostre tasse (come avviene in Germania).

Nell'allegato (link) ci sono i riferimenti per il bonifico.

I sistemi wireless sono inefficienti: bruciano 80 Miliardi di $ !

Around $80 billion wasted on power for online devices in 2013

More Data, Less Energy cover
Simple measures can keep problem of inefficient ‘network standby’ from worsening in years ahead, IEA report says
2 July 2014   Paris
Today, the world’s 14 billion online electronic devices – such as set-top boxes, modems, printers and game consoles – waste around USD 80 billion each year because of inefficient technology. By 2020, the problem will considerably worsen, with an estimated USD 120 billion wasted. But a report by the International Energy Agency points to a different path, identifying simple measures that can be implemented now to improve energy efficiency in networked devices, resulting in massive savings of energy and money.
The report, More Data, Less Energy: Making Network Standby More Efficient in Billions of Connected Devices, shows that electricity demand of our increasingly digital economies is growing at an alarming rate. While data centre energy demand has received much attention, of greater cause for concern is the growing energy demand of billions of networked devices. In 2013, a relatively small portion of the world’s population relied on these devices to stay connected. But energy demand is increasing as a growing share of the world’s population becomes wired and as network connectivity spreads to devices and appliances that were previously not connected, such as washing machines, refrigerators, lights and thermostats.
“The proliferation of connected devices brings many benefits to the world, but right now the cost is far higher than it should be,” said IEA Executive Director Maria van der Hoeven. “Consumers are losing money in the form of wasted energy, which is leading to more costly power stations and more distribution infrastructure being built than we would otherwise need – not to mention all the extra greenhouse gases that are being emitted. But it need not be this way. If we adopt best available technologies we can minimise the cost of meeting demand as the use and benefits of connected devices grows.”
As the report explains, much of the problem boils down to inefficient “network standby” – that is, the maintaining of a network connection while in standby. In many devices, standby is a misnomer: it suggests that the device has gone to sleep and is almost off. In reality, most network-enabled devices draw as much power in this mode as when activated to perform their main tasks.
In 2013, the world’s networked devices consumed around 616 terawatt hours (TWh) of electricity, the majority of which was used in standby mode. Of that total, around 400 TWh – equivalent to the electricity consumed annually by the United Kingdom and Norway combined – was wasted because of inefficient technology.
“The problem is not that these devices are often in standby mode, but rather that they typically use much more power than they should to maintain a connection and communicate with the network,” said Ms. Van der Hoeven. “Just by using today’s best available technology, such devices could perform exactly the same tasks in standby while consuming around 65% less power.”
The report describes technologies and technical solutions as well as a range of policy options that are available to reduce energy waste. It projects that if better energy efficiency measures were applied to online devices in the coming years, 600 TWh of energy would be saved. That’s equivalent to shutting 200 standard 500MW coal-fired power plants, which would cut emissions by 600 million metric tons of CO2.
In the report, the IEA calls on policy makers, standards development organisations, software and hardware developers, designers, service providers and manufacturers to work together to reduce energy demand. To achieve this, the agency urges an international initiative to enhance standards, as the issue is global.

About the IEA
The International Energy Agency (IEA) is an autonomous organisation which works to ensure reliable, affordable and clean energy for its 29 member countries and beyond. Founded in response to the 1973/4 oil crisis, the IEA’s initial role was to help countries co-ordinate a collective response to major disruptions in oil supply through the release of emergency oil stocks to the markets. While this continues to be a key aspect of its work, the IEA has evolved and expanded. It is at the heart of global dialogue on energy, providing reliable and unbiased research, statistics, analysis and recommendations.

La tecnologia Li-Fi sembrerebbe pronta per il mercato : una reale (e sana) alternativa al WiFi ?

 C'è una società russa che ha iniziato a commercializzare in alcuni paesi: USA, Israele, UK, le connessioni via LiFi ovvero connessione senza fili ma senza l'uso di radiofrequenze ma della luce (LED).
E' possibile collegare fino ad otto apparecchiature (che quindi vengono messe in rete) tramite un 'apparecchio' che viene installato sul soffitto.

Essi parlano di vantaggi economici, di velocità di trasmissione (4 volte quella del Wifi) , e di sicurezza dati .  Accennano a compatibilità ecologica . 

Già nel maggio 2013 ne abbiamo parlato: vedere

Chiederò direttamente a loro lumi in merito alla sicurezza per la salute umana (non ho mai ricevuto risposta ad analoga domanda posta ai ricercatori di Glasgow (2013) ...!).




Russian firm’s Li-Fi internet solution winning foreign clients 


June 30, 2014 Dan Pototsky, 

RBTH The Russian company Stins Coman is selling its Li-Fi based solution (a visible light communication technology that uses light from light-emitting diodes to deliver internet) in the U.S., Israel, China, and other countries. Will Li-Fi be able to compete with Wi-Fi’s radio signal in transferring information with speed and reliability?

In April 2014, the Russian company Stins Coman announced that it had developed a wireless local network called BeamCaster. This innovative solution transfers information to electronic devices with the help of light. 

The core of the network is a router that is capable of transmitting a signal using a light beam at a distance of up to 23-26 feet (7-8 meters). The signal can be transmitted to eight devices at once in other parts of an office, and access speed is four times faster than standard Wi-Fi. 

According to its developers, BeamCaster offers several advantages; for example, the mobility and speed of its configuration. Li-Fi is unique in that it creates a digital binary code with a light beam, while Wi-Fi transmits data using radio waves. 

“All you have to do is install the transmission model on the ceiling, configure it toward the receiving modules on the work computers, and you’ll get a working network in the office in just a couple hours that can quickly be disassembled if necessary,” said Dariush Zayents, head of the Russia office of RiT Technologies, a subdivision of Stins Coman that developed this optical technology. 

Another advantage is its speed. BeamCaster’s light module can transfer data at a speed of 1.25 gigabytes per second, which is the guaranteed speed for transferring data to each working unit. In the near future, the developer will be ready to boost that speed to 5 GB/second - significantly faster than the radio signal that Wi-Fi uses. 

“We know that the maximum [speed] that a Wi-Fi network is capable of is 300 MB/second (standard 802.11n). And that’s the speed on the entire channel, not for each connected user,” Zayents explained. 

Scientists have known for quite some time that light waves are good at transferring various types of information. Harald Haas, a professor at Edinburgh University, pioneered the Li-Fi technology when he demonstrated a successful prototype of a device that transfers information using LED radiation three years ago, and even created a company to sell Li-Fi based solutions. 

Among other things, the creators of the new beam technology assert that their solution is much more secure and environmentally friendly than Wi-Fi. 

“As you know, it’s very easy to intercept a Wi-Fi signal,” Zayents continued. “It passes through walls, and hackers can easily connect to a corporate network. Our device only transfers data in a light beam, so it’s impossible to intercept it or eavesdrop on it.” 

In addition to that, the radio signal used by Wi-Fi can interfere with other electronics; for example, certain medical devices. Of no less importance is the inverse relationship; the light beam is not affected by external electromagnetic fields. 


Light beam 

The BeamCaster set, which includes a central device plus eight receivers, is currently going for several thousands of dollars on the market. That is a hefty price tag, which is why for now the producers’ main clients are the offices of major companies, such as U.S. telecommunications innovators Arris (for video applications) and Cortina (for maintaining its engineering center), Israel’s Bynet (for servicing its call center), and China’s Soarsky (six systems for its open engineering offices). 

However, according to the developers, the BeamCaster suite will soon hit stores, with one portal averaging less than $100 in price. Such a price will allow the developers to enter new markets. 

Nonetheless, experts are skeptical about the project’s future. 

“The device has several shortcomings, such as the difficulty of positioning the receivers, the inconvenience of working with mobile devices, and the relatively high cost of implementation,” said Vadim Sukhomlinov, Strategic Business Development Manager at Intel in Russia. “I would assess the prospective market for this device in volume at about 5 percent of what Wi-Fi currently occupies. “That said, the solution itself is really promising and interesting. It could be a decent alternative to Wi-Fi for big companies. Besides that, the speed at stationary devices is very high and much more protected than a radio or wire signal,” Sukhmolinov added.

Belgio: il consigliere della città di Ghent, per la educazione e l'infazia, ha messo al bando il wifi

... nelle scuole della prima infanzia, ovvero per bambini sotto ai tre anni.
La motivazione è essenzialmente la preoccupazione di danni futuri dovuti alle radiofrequenze.




Ghent, Flanders: Ghent bans wi-fi from pre-schools and day care

http://www.flanderstoday.eu/education/ghent-bans-wi-fi-pre-schools-and-day-care




Summary
Ghent’s alderwoman for education and youth has announced a ban on wireless networks in day care facilities and pre-schools out of concern for radiation levels

Radiation feared

As part of a new policy plan for local schools, Ghent’s alderwoman of education and youth has banned wireless internet from spaces that cater to children between 0 and three years of age – essentially, pre-schools and day care facilities. Network cables can still be used in those facilities.
“In schools where they work with tablet computers, wi-fi can remain in place,” alderwoman Elke Decruynaere explained to Het Laatste Nieuws. “We want all children to have access to internet at school, but we also want to be careful. A report has demonstrated that we need to cautious with exposure of young children to radiation through wireless internet.”
Ghent politician Peter Dedecker (N-VA) spoke out against the plan, saying that the negative effects of radiation are not irrefutably proven and that restricting internet access could limit children’s general educational development.
“It’s important for children to get used to technology,” Dedecker told deredactie.be. “There are also a lot of educational mobile applications that teach young children about colours and shapes, for example. It would be a shame if the apps can’t be used because there is no wi-fi at school.”
