Virgin Media O2 beats EE, Vodafone and Three to test new signal boosting tech

Virgin Media O2 beats EE, Vodafone and Three to test new signal boosting tech

Virgin Media O2 has become the first carrier to successfully test a new mobile signal boosting technology. Dubbed Neutral Host In-Building (NHIB), the system is designed to increase the signal indoors for 4G and 5G networks. This will be used in business and public venues, so you won’t lose the signal in car parks, shopping centres, offices, and more.

Although Virgin Media O2 was the first to test NHIB, the technology will work across all mobile networks. So, if the signal boosting system is installed in your local library or train station, your 4G signal from Three or Vodafone will be upgraded so you can continue to send text messages, reply to WhatsApp messages and make calls indoors.

The first test was carried out in London’s Canary Wharf in an unspecified workplace.

With one trial under their belt, we’d expect to see more mobile carriers push ahead with tests of this new technology. As millions leave their homes and return to the office, bringing strong 4G and 5G signals across public and enterprise buildings is hugely important. While there are often public Wi-Fi networks available – many free to join – these often require users to hand over some personal information, including name, email address and phone number to gain access.

BT and Sky offer faster broadband, but they cannot match a new rival

That’s not something that everyone will be comfortable with. Without a VPN activated on your device, it’s possible for gadgets to be vulnerable to a man-in-the-middle style attack, where a scam artist connected to the same Wi-Fi network can intercept traffic from your smartphone, tablet or computer – including key details like payment information during the checkout process, text messages, and more.

Relying on your existing 4G or 5G network in a busy public building removes that risk.

Speaking about the successful trial by Virgin Media O2, director of radio engineering for the company, Omar Calvo said: “Customer experience and mobile connectivity is central to our values and the businesses we support. To deliver a great Virgin Media O2 network experience inside buildings, we are joining with several different industry partners, including Freshwave, to build state-of-the-art shared in-building small cell solutions.

“This technology is aligned to the new JOTS Neutral Host In-Building (NHIB) specification, an initiative led by Virgin Media O2. I’m proud to say Virgin Media O2 is the first UK mobile network operator to support live calls on NHIB small cells and we see this as an exciting milestone for Virgin Media O2 and we believe it will transform the way mobile coverage is delivered into offices and indoor public venues.”

With any luck, we’ll hear more about the progress of this industry-standard technology soon.

‘Strong deterrent signal’ US Air force sends dozens of F-22s to Pacific amid China tension

‘Strong deterrent signal’ US Air force sends dozens of F-22s to Pacific amid China tension

The stealth fighters, which arrived in Guam on Sunday, will take part in a military exercise near the Tinian islands for Operation Pacific Iron 2021. Pacific Air Forces in Hawaii confirmed approximately 25 F-22 Raptors from the Hawaii Air National Guard and from Joint Base Elmendorf-Richardson, Alaska, have been deployed.

General Ken Wilsbach, Pacific Air Forces commander, told CNN the deployment of F-22s will be the US’s largest joint deployment.

He said: “We have never had this many Raptors deployed together in the Pacific Air Forces area of operations.”

Operation Pacific Iron 2021 will focus on deploying, operating, manoeuvring, sustaining and generating forces from smaller and dispersed bases.

The operation is meant to project forces into the US Indo-Pacific Command area of responsibility showing the US to be “a more lethal, adaptive, resilient force”.

Images of the F-22s arriving at Andersen Air Base in Guam were shared on the Defence Visual Information Distribution Service (DVIDS).

According to a statement from Pacific Air Forces, other aircraft from Idaho and Japan will join the F-22s for what the Air Force calls an Agile Combat Employment operation.

The Agile Combat Employment operation will distribute the combat aircraft to other airfields across the region to increase survivability from enemy missile strikes.

Carl Schuster, a Hawaii-based defence analyst and a former director of operations at the US Pacific Command’s Joint Intelligence Center, said the deployment of the Stealth fighters is sending a strong signal to China.

Type 2 diabetes: Four 'serious' foot problems that signal blood sugar damage to nerves

In addition to symptoms, you should also see a GP if you’re worried you may have a higher risk of getting type 2 diabetes, advises the NHS.

Following a formal diagnosis, your GP will usually recommend changing aspects of your lifestyle to bring blood sugar levels under control, notes the health body.

There are two key components of blood sugar control – diet and exercise.

“Diabetes won’t stop you from enjoying your food, but knowing some simple hacks and swaps will help you choose healthier options and make planning your meals a little easier,” explains Diabetes UK.

Vitamin B12 deficiency: A type of body pain may signal you have low B12 levels

Vitamin B12 deficiency: A type of body pain may signal you have low B12 levels

Vitamin B12 is a nutrient that helps keep the body’s nerve and blood cells healthy and helps make DNA, the genetic material in all cells. Given its importance, it is hardly surprising that B12 deficiency can cause a slew of symptoms. Unfortunately, attributing changes in the body to low B12 levels can be tricky because the symptoms are often non-specific.

A study published in the journal Neurology B12 sought to assess the prevalence of non-specific sensory symptoms.

According to the researchers, chronic pain syndrome is commonly reported in people with B12 deficiency.

To investigate the prevalence of this symptom, patients attending the Neurology outpatient clinic, as well as inpatients underwent a test to determine B12 levels.

All patients reported ill-defined chronic pain, and other non-specific sensory symptoms.

There were 70 patients – 19 males and 51 females – enrolled in the study.

Most of the patients reported vague body pain (82 percent), followed by sensory symptoms of limbs (76 percent).

“There is a high prevalence of Vit [vitamin] B12 deficiency in patients presenting with ill-defined chronic pain and other non-specific sensory symptoms,” the researchers concluded.

Other general symptoms of B12 deficiency include:

  • Extreme tiredness (fatigue)
  • Lack of energy (lethargy)
  • Breathlessness
  • Feeling faint
  • Headaches
  • Pale skin
  • Noticeable heartbeats (palpitations)
  • Hearing sounds coming from inside the body, rather than from an outside source (tinnitus)
  • Loss of appetite and weight loss.

How to respond

You should see a GP if you’re experiencing any of the above symptoms of vitamin B12, advises the NHS.

“These conditions can often be diagnosed based on your symptoms and the results of a blood test,” explains the health body.

It’s important for vitamin B12 or folate deficiency anaemia to be diagnosed and treated as soon as possible.

As the NHS points out, although many of the symptoms improve with treatment, some problems caused by the condition can be irreversible if left untreated.

People strictly following a vegan or vegetarian diet are particularly at risk because B12 is generally found in meat, fish and dairy products.

The course of treatment depends on the underlying cause.

Pernicious anaemia, for example, is usually treated with injections of vitamin B12.

There are two types of vitamin B12 injections:

  • Hydroxocobalamin
  • Cyanocobalamin.
