Frequently Asked Wi-Fi Related Questions

Q: What is Wi-Fi?

A: Wi-Fi is a technology used to create wireless networks; its abbreviation comes from “Wireless Fidelity”. Many people refer to Wi-Fi as being “wireless Internet”, because that’s the main use of the Wi-Fi technology.

Often times, people that are using their smartphones in a café are making use of the free Wi-Fi signal provided by the café owners to access the Internet.

 

Q: How old is Wi-Fi?

A: The technology was invented in the late 90s, even though the first devices that used wireless communication didn’t appear until 2000. Companies used lots of cables to connect their computers in a network back then, so Wi-Fi has made everything simple by helping companies get rid of all their network cables.

Later on, hot-spots appeared in hotels, airports, etc., allowing people to connect to the Internet without having to rely on a wired network.

 

Q: What can I do to boost the Wi-Fi signal in my home?

A: Begin by moving your router around, until you find a position that provides the best signal. If this solution fails, you can use SMA antennas and RP-SMA cables to bypass the router’s antennas. This method will allow you to experience a significant Wi-Fi signal boost.

 

Q: What’s with those B, G, N, etc. letters that are sometimes printed on the Wi-Fi devices’ boxes?

A: Technology evolves and Wi-Fi isn’t left behind. Each new standard provides greater speeds, security improvements, greener features, and so on.

If your Wi-Fi devices only support the B and G standards, for example, you are missing out of the faster speeds provided by Wi-Fi N. And faster Wi-Fi network speeds mean faster download speeds, better video streaming, and so on.

 

Q: Are Wi-Fi networks insecure?

A: Yes, many wireless networks are insecure. Since all your data travels through the air, it can be intercepted and decoded. This is why it’s mandatory to use an encrypted Wi-Fi network.

 

Q: Is my computer protected from viruses if I make use of an encrypted Wi-Fi network?

A: No, this step will only prevent people from getting access to your data by spying on your wireless network, but doesn’t do anything against the hackers that want to get inside your computer using the Internet. You will also need a good antivirus program and ideally an antispyware program as well, if you want to keep the bad guys at bay.

 

Q: What is Mobile Wi-Fi?

A: Mobile Wi-Fi is a technology that allows several devices (phones, tablets, laptops, etc.) to share a mobile Internet connection.

In many ways, mobile Wi-Fi is similar with a portable hotspot. If your mobile connection can access the Internet, the connection will then be shared among the connected devices. Internally, Mobile Wi-Fi devices are small modems that also include a 3G SIM. As soon as these modems connect to the mobile phone network, they can start acting like standard Wi-Fi access points.

1. People that have kids younger than five years old and want a free fluoride varnish dental treatment for them can go to McCall, Idaho.

medical newsIt is a well known fact that fluoride is of great help when it comes to preventing cavities in young patients. This initiative targets mostly kids that do not have a personal dentist; this means that the kids that don’t benefit from a dental insurance plan are welcomed to the treatment. The treatment is complimentary, but the parents should enlist the name of their kids.

2. Flu has taken the life of 21 persons, including 2 kids, in Idaho. The flu season has started on the first of October, 2012 and since then many people in the region have suffered from it. Flu is a serious condition that can take lives, even the lives of kids.

The 19 adult patients that died were older than 50; many doctors recommend that the people suffering from various medical conditions should get flu shots. Flu can cause several complications of pre existing medical conditions. For example, flu can be very bad for pregnant women or persons with diabetes and heart disease. Among the flu symptoms there are: fever above 100 degrees Fahrenheit / 37.8 degrees Celsius, trouble breathing, dizziness, confusion, dehydration, vomiting, being sleepy and irritable.

3. About one fifth of the houses in Idaho contain radon, a gas that is the second cause of lung cancer in the U.S., right after smoking. Radon was found in many of the Idaho counties, and actually there are some counties where more than half of the existing houses registered high levels of radon.

This is a radioactive gas that can be found in the soil; it has no smell, taste or color and it is known to determine the death of over 20,000 persons in the U.S. every year. Radon accumulates in larger quantities during winter, when many people keep the windows and doors closed, thus allowing the gas to remain inside the walls of the house. The gas can be found in larger quantities in the basement and the ground floor rooms of the houses.

4. As spring is making itself more and more visible, farmers have also started to replenish the stock of chicks and ducklings. More than that, there are even parents that have thought about getting their kids such a present for Easter. But the Public Health and Agriculture authorities encourage people to be very careful and handle wisely the small birds, due to the high risk of salmonella, which may cause infections.

As more and more people have started to raise chickens and ducks in urban areas, they should be correctly informed concerning the possible risks and the preventative measures that should be taken. They should be taught to wash their hands on a regular basis, never allow the birds to get in the house, as well as clean all the potentially contaminated areas often.

5. Residents of SW Boise attended a class where they were taught how to prevent debilitating falls that can happen at senior age, a fact that can leave them incapable of moving on their own. Simple exercises have been practiced, and they proved to be helpful the seniors’ strength, balance, mobility and endurance.

Global Warming News

The sun has always been a real blessing for life on Earth, and all over the world people try to find ways to use the solar energy in diverse ways that will help us improve our lives.

global warming newsBack in time people learned to use mirrors and ignite a fire using the rays of the sun. Ancient history tales told us about the creative Archimedes, who used bronze shields to set enemy ships on fire by concentrating the solar energy. Nowadays, after the people have learned to use the water, the wind and coal to make energy, scientists all over the world are still trying to find ways in which they can transform the solar energy into electricity with a much greater efficiency.

A group of scientists from The Department of Chemistry, Chemical Engineering and Materials have come up with a brilliant idea that would transform the solar energy into electricity using metals. It is a large research effort that seems to be different from all other similar projects. The scientists have developed devices that can convert the sun energy into electricity by using semiconductors, which are rich in electrons on one side only. The light particles excite the electrons and as a result, these charged particles are created and they can then be captured and used to light up bulbs, for example.

It is not all good news, though. Many nations of the world are worried because of the global warming, and many countries have stated their commitment to fight against global warming, estimated to be about two Celsius degrees higher in comparison to the pre industrial period.

In fact, new studies published by Science Magazine have demonstrated that a raise with only 1.5 degrees of the global temperature has a huge impact on life on our planet. Not only that, but scientists have noticed that in Siberia’s caves, the permafrost begins to melt if the temperature rises with only 1.5 degrees Celsius. If this is really going to happen, experts talk about an impact similar to the release of a 1,000 giga tones bomb.

The permafrost covers about 24 percent of the land surface of the Nordic hemisphere, and if this area begins to melt, the sunlight and the bacteria would have a big impact on the previously frozen plant components. This would mean, in the end, that carbon and methane are released in the air in huge quantities. At this moment there isn’t any viable solution that would allow us to limit the raise in temperature that takes place in the entire world.

The raise in global temperature has been recently linked to the decreased work capacity that people have. In fact, not just the heat affects us, but the high humidity as well. Scientists from the National Oceanic and Atmospheric Administration have concluded that due to the climate change, life in different regions on Earth will be completely changed.

The most pessimistic estimations say that around the year 2050, due to the association of high temperatures and high levels of humidity in the air, about 80 percent of the work capacity of people will decrease, especially during the hot summer months, every year. The impact would actually be twice as big as what we are facing today.

When the levels of humidity are high, people can find it very difficult to cool their bodies; perspiration is affected and heat related illnesses will occur. The specialists estimate that over a period of fifty years, if people do not invent new modalities to cool the air and keep the temperature values low, the average Earth temperature would be eleven degrees Fahrenheit higher in comparison with what it was in the preindustrial period.

Idaho News

1. Several people have decided to get their heads shaved in order to help cancer research in Boise, Idaho. The participants have asked for money from their friends and family members, in exchange for the privilege to see them go bald. The money gathered was donated to a children’s cancer research fund. The event is organized every year.

2. A new study has showed that money can buy willpower indeed. People on a diet could win or lose 20 dollars a month if they enrolled in a program created to help them lose pounds. The program was conducted at Mayo Clinic and was the longest to demonstrate that money given as incentives had a great power making people lose weight. On the other hand, people had to pay money if they could not lose weight.

3. After a woman turns 50, losing weight gets more and more difficult. One explanation is the hormone change in her body: the cortisol level increases and this makes the body store more fat on thighs and stomach.

Specialists have noticed that once a woman gets older, the muscle mass is declining, and muscles are replaced by fat. The good news is that doctors can create personalized diets for each woman and if seriously kept, these diets can help a lot.

4. Older people are not at all helped by the flu shot that has been used this year; only 9 percent of the old people state that the flu shot has helped them. As a result, many older people have been hospitalized with flu this year.

5. A new Vein Center in Idaho is presenting the next generation of medical services offered to patients with swollen veins. Half of all Americans over 50 and close to two thirds of women over 60 have this problem. The varicose veins are sometimes visible in the teenage years as well.

This is a condition that is genetically transmitted from generation to generation, so if your mother had this medical problem, it is very possible that you are going to have it as well. The physical activity is very helpful to prevent or postpone the start of the problems. It is a progressive condition that gets worse if not treated properly.

6. Cinnamon has proved to be of great help once again, and specialists recommend incorporating it in our diets on a regular basis. It prevents and combats diabetes, as it behaves in the organism like an insulin substitute for persons diagnosed with type 2 diabetes.

This is a recent result of a study conducted by the University of California, Santa Barbara, the U.S. Department of Agriculture and Iowa State University. Since cinnamon is capable of potentiating the insulin in the body, the conclusion is that it has the potential to prevent and overcome diseases like diabetes.

7. Due to the Daylight Saving Time, people lose one hour of sleep and this is very dangerous for those that drive a car in the morning. The risk is to get sleepy while driving, says the National Transportation Safety Board.

March 3-10 was elected to be the week of National Sleep Awareness Week, which was planned as an event that highlights tragedies that are caused by sleep loss. Sleep deprivation is strongly linked to the mistakes drivers make when driving their cars.
