5G Will Give Operators Massive Headaches – Bell Labs



5G Will Give Operators Massive Headaches – Bell Labs

The Massive MIMO antennas expected to be at the heart of so-called 5G next-gen mobile networks will come with some major challenges because of their huge size, according to Tod Sizer, head of access technologies research at Bell Labs , part of the Alcatel-Lucent (NYSE: ALU) empire. (See AlcaLu Breathes New Life Into Bell Labs and Prepare for a 5G Onslaught.)

He says operators will face a creative challenge in deploying 5G basestations in downtown areas.
"They're very flat, they're very large, and they'll never go on top of the big towers because there's too much wind blowing," Sizer said. "But you can hide them in the facades, say, right behind advertising billboards or on the side of walls or buildings."

Of course, even before they are deployed, there's no shortage of technical hurdles to be overcome to build antennas of that power and complexity.

No more than six MIMO (multiple input, multiple output) antennas are deployed in a 4G basestation, but 5G MIMO will likely involve hundreds, Sizer predicts.

"If you want to make 100 antennas work together, you need to get the costs to the point and the size and the weight and the power to be low enough so it's economic to deploy. The challenges we have in the digital processing are as severe as the heat and size issues."

Sizer said Massive MIMO would be likely deployed only in high-density urban areas. He describes it as "a wonderful technology for Singapore," where most people live in a high-rise, but wouldn't be required for medium-density suburbs.

He said that whereas 4G was primarily about the radio, the big challenge for 5G would be to create a user- or application-aware network with a focus on end-to-end performance.

"We know what the application is, we know what the network is. How can the network adapt to that particular woman, with that particular application, in that particular place?"

As well as the obvious issues of bandwidth and latency, 5G would also have to provide "responsivity," which Sizer describes as the ability to create a session, complete the operation quickly, and shut it down.
"For an app like search, that's critical… if I can create a connection, use it and then shut down the connection, that allows me to use the network less. That has impacts on the capacity of the network; it also impacts battery life."

He says the industry will need to get creative to acquire the spectrum resources necessary for 5G, such as millimeter waves or the use of LTE unlicensed spectrum through carrier aggregation.

He also points to under-used 5GHz bands used for radar surveillance near airports. "We're working with the federal government and the FCC to share that spectrum. If you're not within 100 kilometers of an airport, why can't I use it? Or use it when the radar is pointed in other directions?" asks the Bell Labs man.

Vitamin E prevents glucose metabolism alterations induced by static magnetic field in rats.

 2014 Jun 27. [Epub ahead of print]

Vitamin E prevents glucose metabolism alterations induced by static magnetic field in rats.

Ghodbane S1, Amara S, Lahbib A, Louchami K, Sener A, Sakly M, Abdelmelek H.

Abstract

In the present study, we investigate the effects of a possible protective role of vitamin E (vit E) or selenium (Se) on glucose metabolism disruption induced by static magnetic field (SMF) in rats. Rats have been exposed to SMF (128 mT, 1 h/day during 5 days). Our results showed that SMF failed to alter body weight and relative liver weight. Our data demonstrated that exposure to SMF increased (+21 %) blood glucose level and caused a decrease (-15 %) in liver glycogen content. Moreover, the same treatment induced a reduction of pancreatic islet area. Interestingly, supplementation with vit E (DL α-tocopherol acetate, 150 mg/kg per os during 5 days) prevented alterations induced by SMF on glucose metabolism and liver glycogen content, whereas supplementation with Se (Na2SeO3, 0.20 mg/l, in drinking water for 4 weeks) restored only hepatic glycogen contents. By contrast, both vit E and Se failed to correct the area of pancreatic islets.

Experience: my dog found my cancer

Experience: my dog found my cancer


'None of the oncologists I met was sceptical about Mia's role in diagnosing my cancer – they have heard it before'
experience: Emilie Clark with dog Mia
Emilie Clark with Mia: 'She fixed her eyes on mine and stared intently. She seemed certain there was a problem.' Photograph: Mark Chilvers for the Guardian
I met my miniature dachshund, Mia, at a rescue centre five years ago. She was one of a litter of 12-week-old puppies confiscated from a puppy farm. I hoped she would be my assistance dog for my health problems. Since birth, I have suffered with a type of heart arrhythmia called ventricular tachycardia. My heart races and, if I don't take medication immediately to slow it, I lose consciousness. I've had to be rushed to hospital to have it restarted. Unrelated to that, at 19 I started to lose my hearing and now struggle with high-pitched sounds such as the phone or doorbell ringing.
I was studying to be a vet, so the idea of having an assistance dog appealed to me – I love animals. The theory was that Mia would alert me when the phone was ringing or when my heart rate was speeding up and I had to take emergency medication. When she was 16 weeks old, she was assessed by a charity that trains pets to become assistance dogs. I hoped the immediate and instinctive bond Mia and I shared when we met meant she'd be suitable.
She qualified as my assistance dog just before her second birthday. Mia learned to alert me just before my arrhythmia starts by making a horrible screeching noise and jumping up at me. She ferrets in my handbag and brings me my heart medicine. She puts her paw on my leg to inform me when the phone's ringing. Once we were in B&Q when the fire alarm sounded and, executing her training perfectly, she lay on the floor and stared at me, hard, to tell me a siren was blaring.
One evening in November 2011, I was at my computer when Mia leapt on to my lap and nuzzled into the flesh at the top of my left breast. She closed her eyes and licked furiously. That frightened me because it's what she does when I have a bruise or cut.
I pushed her gently away but she fixed her eyes on mine and stared at me intently, as she does when she's alerting me to something. I was uneasy now. Mia seemed certain there was a problem with the area at the top of my breast. I couldn't distinguish anything – my breasts are naturally lumpy – so it was difficult. All evening Mia attempted to leap on to my lap and tend to the area of skin where she perceived a problem. The following morning, I visited my GP with a sense of dread. I asked for an ultrasound or a mammogram. I didn't start the consultation by telling him that my dog had alerted me to the possible abnormality – I was aware it might sound far-fetched, but when he was dismissive, saying it was unlikely I had breast cancer because I was only 24, I explained.
"I know dogs detect cancer and my dog is determined there's something wrong with my breast," I said firmly. Then I informed him that, as I trusted my dog, I wasn't leaving his surgery until he'd made me a hospital appointment.
My faith in Mia's diagnostic abilities wasn't misplaced. I had an ultrasound within a week and, sure enough, there was a lump that a biopsy later confirmed was grade 2a breast cancer. Two days later, I was in surgery having the lump removed. Then I started radiotherapy – five days a week for three weeks. I was angry. I was only 24 and I'd already suffered so many health problems.
It made everything else harder. Training to be a vet requires 100% dedication and, with fighting cancer and having intense and exhausting radiotherapy, I couldn't give that, so I had to drop out of university. They were really hard times. My relationship broke up and I had to move back home with my parents. Mia was by my side through it all. Cuddling her after bad news or a gruelling session of treatment alleviated some of the pain.
None of the oncologists I met during my ordeal was sceptical about Mia's role in diagnosing my cancer – they had heard it before. There's a charity called Medical Detection Dogs that trains dogs to sniff out cancer, and its work is endorsed by Cancer Research UK. Scientists are researching how dogs possess this diagnostic ability so that humans can harness it.
Fortunately, my cancer hadn't spread but it will be another 16 months of scans before doctors grant me the all clear. Meanwhile, I'm rebuilding my life. No matter what life serves up, the bond between Mia and me will always be incredibly strong.

Selenium Reduces Mobile Phone (900 MHz)-Induced Oxidative Stress, Mitochondrial Function, and Apoptosis in Breast Cancer Cells.

 2014 Jun 27. [Epub ahead of print]

Selenium Reduces Mobile Phone (900 MHz)-Induced Oxidative Stress, Mitochondrial Function, and Apoptosis in Breast Cancer Cells.

Kahya MC1, Nazıroğlu M, Ciğ B.

Abstract

Exposure to mobile phone-induced electromagnetic radiation (EMR) may affect biological systems by increasing free oxygen radicals, apoptosis, and mitochondrial depolarization levels although selenium may modulate the values in cancer. The present study was designed to investigate the effects of 900 MHz radiation on the antioxidant redox system, apoptosis, and mitochondrial depolarization levels in MDA-MB-231 breast cancer cell line. Cultures of the cancer cells were divided into four main groups as controls, selenium, EMR, and EMR + selenium. In EMR groups, the cells were exposed to 900 MHz EMR for 1 h (SAR value of the EMR was 0.36 ± 0.02 W/kg). In selenium groups, the cells were also incubated with sodium selenite for 1 h before EMR exposure. Then, the following values were analyzed: (a) cell viability, (b) intracellular ROS production, (c) mitochondrial membrane depolarization, (d) cell apoptosis, and (e) caspase-3 and caspase-9 values. Selenium suppressed EMR-induced oxidative cell damage and cell viability (MTT) through a reduction of oxidative stress and restoring mitochondrial membrane potential. 
Additionally, selenium indicated anti-apoptotic effects, as demonstrated by plate reader analyses of apoptosis levels and caspase-3 and caspase-9 values. In conclusion, 900 MHz EMR appears to induce apoptosis effects through oxidative stress and mitochondrial depolarization although incubation of selenium seems to counteract the effects on apoptosis and oxidative stress.

$80 water meter fee slammed

$80 water meter fee slammed

City council has approved it, but an $80 fee to read the water meter is excessive, says Councillor James Pasternak.


Jessica Annis, who doesn't want the city to install a smart water meter in her home, holds up a no trespassing sign. She wants to continue to report the numbers for her meter readings herself.

Jessica Annis, who doesn't want the city to install a smart water meter in her home, holds up a no trespassing sign. She wants to continue to report the numbers for her meter readings herself.
The City of Toronto will soon start charging $80 to manually read water meters of customers who refuse new wireless meters. Based on three readings a year, that’s an extra $240.
At least 3,341 customers who don’t want the smart meters that automatically transmit readings are being warned by the city they could also be fined up to $50,000 and have their water cut off.
While objectors want to continue sending in their readings, Toronto Water notes the new program as approved by city council is mandatory for all customers.
The city should try to accommodate people rather than slap them with a “draconian” $80 non-compliance fee, said Councillor James Pasternak.
“This is really a far reach for big government to be coming down so hard on homeowners,” he said.
The city’s water department expects to save $5 million annually by getting rid of manual meter readings.
More on the star.com
Longtime Toronto resident Shelly Lee said the potential savings could come at a price. “We know that these wireless systems are hackable,” she said.
Critics of wireless water meters in the U.S. have pointed out that transmissions aren’t encrypted, so readings can easily be altered or the signals can even be jammed. There’s also the possibility of customers abusing the system by finding ways to manipulate the wireless meters.
“My current meter works just fine,” Lee said. “I will not let Neptune (the installer) into my home to replace it.”
Toronto Water says out of 242,000 accounts in areas where the program has been completed, holders of 2,368 metered accounts either outright refused access or ignored as many as nine contacts from the city, including a registered letter. They will be subject to the $80 fee every time their meter is read.
In the same completed areas, another 973 customers with no meters who pay a flat rate have refused to move to the new meters and they will be subject to an annual fee of $1,020 for water.
Residents, including Lee, have cited concerns about radio frequencies from the wireless devices, prompting Toronto Public Health to issue a statement that the transmissions — which last for one second a day — are unlikely to pose a health hazard.
But Lee said exposure to additional radio frequencies in a world that’s being inundated by various cellular, radio and other wireless transmissions is just another possible health risk.
She doesn’t understand why residents couldn’t have the option of sending in water readings online or over the phone.
Midtown resident Darlene Allan said she’s been calling in her reading for 20 years and doesn’t understand why the city won’t let her continue.
“It seems like the city is taking something that isn’t broke and trying to fix it,” Allan said, adding she didn’t appreciate the city “threatening” people with potential huge fines and cutting off their water supply.
East-end resident Jessica Annis doesn’t want to hand over access to her property so the city can install a device that could compromise her privacy if the system were hacked.
“They say this isn’t hackable, well everything’s hackable,” Annis said. “I have privacy concerns. I have other concerns. They don’t have authority over my private property.”
In many cases, the reasons for people not co-operating are unknown because the customer simply hasn’t responded to any of the contacts, said Anthony Fabrizi of revenue services.
The new fee, previously approved by council, takes effect July 1. At budget committee recently, Pasternak tried but failed to have the fee delayed to Dec. 31.
Pasternak objects to the fee and the “threatening” warning letter that says allowing access is mandatory under city bylaws and notes that failure to comply is an offence carrying a maximum $50,000 fine, and could result in the water supply being turned off.
“I think in general electronic meter reading is a solid policy but it’s very important when you bring in new measures that you do so with a soft landing,” he said. “I think it’s important to show leniency.”
In a report, the city said the meter reading fee could serve as an incentive for people to accept automated meters, and added that $80 is the city’s actual cost of sending someone out to do a manual read.
Toronto Water general manager Lou Di Gironimo said the program has been successful in that all but 1.3 per cent of customers in completed areas have balked.
“That’s a pretty good success rate,” Di Gironimo said. “The people that have completely ignored us or just said no, council decided we should be able to charge non-compliance fees because there will be extra costs to manage those accounts.”
Unlike Pasternak, Councillor Gord Perks supports the fee.
“The principle should be to recover our costs,” Perks said. “If someone wants a service other people don’t get, they should pay the cost of that special service. Otherwise, they’re asking everyone else to subsidize them.”
In approving wireless meters, city council was told they would help detect leaks by more closely tracking consumption. It noted customers are notified to check for leaks if their daily consumption is three times the average.
The program also targets flat rate customers who have no meter and tend to use more water than the flat rate covers. The $1,020 annual fee covers the city’s estimate of actual water consumption.
Pasternak said he didn’t have a problem with the new flat rate charge because customers should pay for the water they use.

The world's first cesium-capturing dietary supplement
Cesium Eliminator, Formula 137, is the world's first dietary supplement that's scientifically proven to bind with and capture cesium isotopes.*

Why cesium? Because Cesium-137 is the single most destructive radioisotope that threatens life following:

- A nuclear accident
- An act of nuclear terrorism
- An act of nuclear war

In all three scenarios, cesium-137 is the most devastating, long-term radioactive contaminant that threatens water supplies, food supplies and human populations. Cesium-137 has a 30-year half-life and persists in soils for 200 - 300 years, rendering those soils unusable for agriculture.

About Cesium-137, the U.S. Centers for Disease Control says:

Exposure to Cs-137 can increase the risk for cancer because of exposure to high-energy gamma radiation. Internal exposure to Cs-137, through ingestion or inhalation, allows the radioactive material to be distributed in the soft tissues, especially muscle tissue, exposing these tissues to the beta particles and gamma radiation and increasing cancer risk. (1)

And here's what the EPA says about Cesium-137:

Cesium-137 that is dispersed in the environment, like that from atmospheric testing, is impossible to avoid... People may ingest cesium-137 with food and water, or may inhale it as dust. Like all radionuclides, exposure to radiation from cesium-137 results in increased risk of cancer. (2)

Cesium-137 is deadly, and that's why this breakthrough product, Cesium Eliminator Formula 137, can be such a lifesaver in emergency situations.

The perfect preparedness companion with potassium iodide or nascent iodine
Many people have stockpiled iodine sources for strategic protection against radioisotopes of iodine such as Iodine-131. Nascent iodine protects the thyroid from radioactive iodine isotopes.

While nascent iodine (or potassium iodide) is a wise choice for preparedness against radiological disasters, it's only a half-measure because it offers zero protection from radioactive cesium-137 fallout.

Cesium-137 fallout quickly contaminates open water sources such as rivers, streams and lakes. When those sources are used as public water supplies, the home tap becomes irradiated with cesium-137. Drinking radioactive water can be fatal.

Cesium Eliminator offers the best binding with cesium isotopes, providing a layer of defense that iodine-based products simply can't address.* That's why the well prepared are going to want to add Cesium Eliminator to their preparedness gear, possibly right alongside nascent iodine. (The two products should not be consumed simultaneously, however, because iodine can reduce Cesium Eliminator effectiveness. See CesiumEliminator.com for full details.)

Anyone in the business of preparedness, survival, "prepping" or public safety will want to consider becoming an affiliate for this innovative, breakthrough product. It begins shipping next week.

The official donation announcement will be launched in just a few days, providing a contact point where members of these organizations can request such donations.

My aim is to get this product into as many people's hands as possible, to help prepare them against nuclear accidents, nuclear war or nuclear terrorism.

You can help us in this mission -- and earn a healthy affiliate commission at the same time -- by joining our affiliate program and placing banners or text links on your own websites or blogs.

Help pioneer the launch of the world's first cesium-capturing dietary supplement
With the launch of Cesium Eliminator, we are making history together! You can join in that history by helping spread the word (and earning an affiliate commission in the process).

Believe me when I tell you that Cesium Eliminator will be impossible to get during the next nuclear accident or disaster. Those who want to be protected from radioactive cesium-137 in water or food will be highly motivated to stock up now while the supply is available.

This is a product that can literally help change the course of human history by giving victims of nuclear disasters a powerful, scientifically-validated tool to protect their safety and help defend their lives.* You can be part of this effort to help save lives and deploy a lab-validated dietary supplement that can literally help protect lives in an emergency.

Warnings and emergency medicine notes
Cesium Eliminator is NOT a replacement for urgent medical care. It is not a treatment for radiation poisoning. Anyone suffering from acute radiation poisoning should seek immediate, urgent hospital care. No dietary supplement blocks radiation (due to the laws of physics). Cesium Eliminator is for emergency use only and is NOT a vitamin or mineral supplement, nor a daily multivitamin. See www.CesiumEliminator.com for full FAQs, notes and warnings.

THE WORK OF OLLE JOHANSSON

THE WORK OF OLLE JOHANSSON

Dr. Olle JohanssonIn the 1970s the newspaper industry was one of the first to supply its employees with computers. Complaints of visual problems and headaches, as well as clusters of miscarriages and birth defects in children born to female editors and other newspaper employees, generated some publicity. In the United States, then-Representative Al Gore held Congressional hearings in 1981 on the health effects of computer screens. In Sweden, a union activist brought the problem to the attention of Dr. Olle Johansson, a neuroscientist at the world-renowned Karolinska Institute. Johansson was the head of the Experimental Dermatology Unit at the Institute.
“For me,” said Johansson, “it was immediately clear that persons claiming skin reactions after having been exposed to computer screens very well could be reacting in a highly specific way and with a completely correct avoidance reaction, especially if the provocative agent was radiation and/or chemical emissions — just as you would do if you had been exposed to e.g. sun rays, X-rays, radioactivity or chemical odours.”
Johansson began to study the skin of these patients, and proved that they had a real skin condition that was provoked by sitting in front of a computer screen. The damage was similar to that caused by ultraviolet radiation from the sun. He also showed that the radiation from computers causes measurable changes even in the skin of “normal” people,” and also in the skin of laboratory animals.
He named the new disease “screen dermatitis.” However, since such individuals also usually complained of other symptoms, such as chest pain, memory loss, fatigue, insomnia, dizziness, nausea, and headache, the more general term “electromagnetic hypersensitivity” came into use.
Many people who worked in the electronics industry in Sweden, including an estimated 12% of the electrical engineers in that industry, became electrically sensitive, and helped form an organization called Föreningen för el-och bildskärmsskadade (Association for the Electrosensitive), or FEB. Due in part to the work of FEB and the research of Dr. Johansson, electrosensitivity is a fully recognized disability in Sweden.
Dr. Olle JohanssonMore recently, Johansson and his colleagues have conducted important epidemiological studies showing that wireless communication networks are causing significant illness throughout society. They have also shown that increased rates of asthma as well as certain types of cancer were strongly correlated with exposure to radio broadcasting during the twentieth century.
“The world may be moving inexorably,” Johansson warns, “toward one of those tragic moments that will lead historians to ask: Why did they not act in time?”
