ABSTRACT Inthe first part we will talk about wireless technologies and how viriletechnology has been affected by the wireless revolution.
We will say who is theengine of this revolution. We will talk about the generation of mobilenetworks. And we will see our belives how will wireless technology outperformthe traditional way of doing business.We’lltalk about wirless media.
As wireless communication takes place through the airin a space where physical lines or cables do not mediate. Also, in wirelesscommunication, various wireless media are used. We will talk about how wirelessmedia function and how they are applied.Wewill also touch the wirless standards, say something about him, see thedifference between them and list them. We will also mention what computernetworks and what types of computer networks exist.
Wealso see how wirless technologies have a negative impact on the health ofchildren and how they affect them. we will also say something about theintensity of the radiation of the mobile phone. we will read that wirelessradiation affects the cell membranes and cells in the human organism. Also, aschildren are particularly sensitive to wireless radiation signals because theirnervous systems are even more uplifting.
we will see that the World HealthOrganization has recognized that wireless technology is a potential carcinogen. Wewill see how wirless radiation is dangerous for humans, its relate on mobilephones, wireless headphones, bluetooth devices, and wireless devices. we willread tips on how to avoid wirless radiation or, at the very least, reduce it. Wewill broaden how wirless technologies are the causes of many diseases. Giventhat this is still somehow a new technology, studies on long-term effects onhealth have not been carried out. Many health professionals believe thatwireless radiation is extremely dangerous for long-term health. They believethat there is a possibility that we will face the tumor epidemic in the futurethat will result from uncontrolled mobile phone use and increased exposure ofthe population to wireless devices.
Many studies have shown that there is nosignificant link between the use of mobile phones and human health, if it isused within the limits of short-term and normal daily use, but due to the rapidgrowth of number of users, extensive surveys are being launched INTRODUCTION Inorder for the Internet as a modern information technology to contribute to theprogress of humanity, its future development should be directed, starting withthe principles of humanities that still need to be built up in accordance withthe digital age in which the world is increasingly rapid.CurrentInternet users are mostly complaining about speed. As the number of Internetusers grows with increased demands on audio and video, the situation isdeteriorating. Initially, the US government invested heavily in the developmentof the Internet. Since 1995, it has interrupted all funding and has taken overits own organizations to control the development of the Internet.Inthe beginning, the internet is used to download textual content such as e-mailor text file transfer.
Then there was no need for fast internet. Today, when itis steadily stealing for business purposes with a greater need for multimediacontent, the existing Internet has become slower. The information industryseeks to build fast internet components – fast routers, optical cables of therequired capacity, and reliable satellite transmission.
The impression is thatthe key problem is in the cost of purchasing earth and purchasing the soil. Inaddition, there is a problem of monopoly power of local telephone companiesthat hold high prices for high speed services and the Internet will slowlyreach private homes.TheInternet, however, has two main goals: the first is the high speed ofconnection and data transmission, and the other high-quality services. Thesetwo goals are gradually achievable. The gigabit performance of the Internetinfrastructure provides high transfer speeds. It is expected that this willsoon meet the high demands of e-commerce, as the new economy and e-commercerequire reliable, fast transfer and high quality. For now, the Internet isstill reserved only for academic and government users. But it is realistic toexpect the Internet, due to its performance, will soon be commercialized.
WIRELESSTECHNOLOGIES Alltrends and reality indicate that the world has been affected by the wirelessrevolution. The launcher of this revolution is a mobile phone, which is nowalmost an indispensable means of modern communication. Mobile phones,affordable prices for mobile communication and numerous services have floodedthe world.
Statistics show that the number of mobile phones exceeded the numberof fixed phones. The annual number of subscribers is increasing by nearly 200million new ones. In the United States, over 60% of the population has mobilephones, Western Europe close to 90%. Asian nations about 70%. China, like manyother things, is a mobile giant. It is assumed that it now has about 400million mobile phone users. It is predicted that in a few years it could haveover 600 million users of mobile devices.
It is estimated that mobile phoneusers pay their operators nearly 50 billion dollars annually. Obviously, themobile telephony industry is profitable. It is therefore understandable thatthe world records $ 200 billion of investment in the third generation of mobiletelephony, which is designated as 3G. (Jelic, 2015)Thefirst generation of 1G mobile networks originated in the early 1980s and wasanalogous.
It provided voice communication, and text transfer was possible witha good modem. The second generation of 2G appeared ten years later and useddigital networks. Voice transmission was better, global roaming and supportedtransmission of simple data as a stamp message. Data transmission is up to 14.4 Kbps, which is very slow for convenient internet access. The third generationof 3G mobile networks is based on the data transfer technique in a series ofpackages. This technology provides greater efficiency and speed oftransmission. 3Gs have a speed of 144 Kbps, even a mobile in-car use, and up to2 Mbps if the mobile is not in use on the go.
This speed is suited for internetconnection and for the use of available Internet services such as e-mail, Web,etc. Between 2G and 3G appeared 2.5G that uses the existing infrastructure andhas a transfer speed of 50-144Kbps. This generation used an internet access.(Jelic, 2015)Mobilephones today have much wider application than voice communication.
They becomenew platforms for the transfer and processing of data, such as computers.Powerful processors, miniaturization of components with new technologies, beingbuilt into mobile phones, expanding the power of wireless networks and openingup space for new roles of mobile devices. They are already successfully usedfor numerous mobile applications, such as: downloading images, sounds, videos,various games, accessing the Internet. There are several users who use themobile phone for business purposes: mobile shop, mobile banking, field work andareas where there is no wire communication.WIRELESS MEDIA Wirelesscommunications take place through the air in a space where physical lines orcables do not mediate. In wireless communication, various wireless media areused. All wireless media rely on various parts of the electromagnetic spectrum.Microwave or infrared waves occupy a specific range of frequency ranges.
Mobilephones and paging systems use a specific range of frequencies that are definedby national monitoring agencies based on an international agreement. Eachtelecommunication transmission medium or device occupies a different range offrequencies, measured in megahertz, on an electromagnetic spectrum. Microwavesystems transmit high-frequency radio signals through the atmosphere and arewidely used for cross-communications. Satellite communications are suitable forthe transmission of large-scale data at a great distance. A number of resourcescan be used for wireless communication. These include mobile phones,, palettes,smartphones. The future belongs to PDA, Today and computers use wirelesstechnology to connect to peripherals – keyboard, mouse, printer. It’s aboutbleuting technology.
WIRELESSSTANDARDS Digitalmobile services use different competitive standards that do not communicatewith each other. The world except the United States uses the GSM standard (GlobalSystem for Mobile Communication). The world is dominated by the GSM standard,because it is used by 75% of mobile phone users. The GSM standard works at afrequency of 1. 8 GHz. In the US, the standard is 1. 9 GHz. (Mitchel, 2017)Thismeans that the US mobile phone system is not compatible with the rest of theworld.
In the US, GSM is not standard because the Federal CommunicationsCommission has allowed open competition in mobile telephony technology. Thatled to diverse standards that do not support roaming. The main US standard isCDMA (Code Division Multiple Access) (Mitchell, 2017)Mobilephones and PDAs can be used to access the Internet and the web. To achieve thiscommunication, a special WAP (Wireless Application Protocol) standard has been created.This standard allows wireless devices that have small screens and great memoryto access web information. WAP uses Wireless Murk up Language.WIRELESS INHEALTH PROTECTION Theactivity, which, by its nature, such as plenty of paper, the constant change oflocation of medical personnel, the strong dynamics of business processes,especially in urgent situations, simply requires wireless communication. Manyhospitals have wired networks on which the information system is based.
Thisoften creates a situation where information is not available at the right timeand at the right time. Mobile technologies can solve some of the problems ofpoor coordination. The benefits of using wireless technology in medicine are:1.
Getting Electronic Medical Documents – Healthcare personnel can use wirelesspalmtops to inspect medical documents, including diagnostic information in realtime. They can scan the data immediately and alert the patient’s dossier whilevisiting patients.2Whitememos that are listed on booster lists – doctors and nurses can enter dataelectronically into a wireless PDA, smartphone, or laptop.3.
Resultsof laboratory analysis – doctors can immediately obtain laboratory test datafrom a wireless PDA, smartphone or laptop4.Recipe / Medicines – medical staff can use a mobile phone, a wireless laptop,to send prescription drug users, reducing delays and errors5.Medical databases – Medical staff can control references to medicines and othermedical information about patients (diagnosis, therapy, chronic illness,allergy medicine, blood group), wherever they work in any situation byconnecting wirelessly to medical databases .
THE IMPACT OFWIRELESS TECHNOLOGY ON HEALTH OF CHILDREN Thereis no space in which a person works, lives or sleeps, and in which there is noharmful radiation. Wireless technology refers to the transmission ofinformation between two or more points that are not physically linked. Itsorigin dates back 200 years ago. SAR represents the amount of energy the skinabsorbs when exposed to electromagnetic radiation. In other words, it is thestrength of EMtalas absorbed by a certain mass of human tissue. When it comesto radiating the mobile phone, the SAR represents the maximum power per unitmass absorbed by the user’s headphone at a certain time.
Electromagneticradiation is a combination of oscillating electric and magnetic fields thattravel together through space in the form of mutually vertical waves. Theradiation intensity of the mobile phone is different at different stages of theconnection. The most intense radiation is in the reporting stage and decreasesin phasing.
Therefore, it is recommended that the mobile phone be locked in theear only after it is established. Manufacturers of mobile phones are obliged toindicate the SAR value in the technical characteristics of the apparatus.AnIndian study has been recognized in the world that investigated the geneticdamage of the blood cell in the lungs of the lips of a person using mobilephones a day from one to fifteen hours. The control group in this experimenthad never used a cell phone, so the damaged cells amounted to about 4 %.
Incell phone users, average cell damage was 39.75%. The blood of one of the24-year-olds showed a cell damage of 63 percent. He used the cell for 1 to 2hours a day for two years. It is today the norm of millions of children of theworld.TheFrench Minister of Health advised that children should not be allowed more than6 minutes of conversation daily. After the nuclear disaster in Chernobyl,workers were working on the cleaning of the plant for several minutes.
In theUS and Canada, profits completely blocked all serious inquiries. In America,the cost of wireless communications is billions of dollars, and even theheadmasters even suggest that their children are more secure when they are incontact with them. A natural mobile phone is the right thing to do. The Serbiangovernment does not advertise this issue at all, although the incidence ofcancer in children and adults has been on a massive increase in recent years.Ifit is believed in all the above research, the number of cancer will increaseyear after year. But how do you imagine a modern world without wirelesstechnology? On the other hand, these sun-and-large companies that realize enormousprofits on wireless technology and to maximize their profits will announce tothe public that such technology can not be harmful, of course, co-operatingwith a scientific institute.
Opening funds for expensive treatment withchemotherapy and x-ray will be established and charged on all sides. Thereare recommendations in Austria. France, Germany and Sweden, that you do nothave to hold your mobile phone handset, that you need to use hands-free toreduce radiation on your head and not use a mobile phone in a car without anexternal antenna.
Electronicdevices with wireless technology connect to wireless computer networks(wireless LAN) using electromagnetic radiation. They are installed in homes,schools, offices, shops, cafes, airports, libraries, hospitals, publicbuildings and entire parts of the city. Wireless signals, unlike TV and radiosignals, are strong enough to penetrate the concrete walls. Many healthprofessionals believe that wireless radiation is extremely dangerous forlong-term health, especially for children, for developing people.Wirelessradiation penetrates into the body, affects cell membranes and cells, and thusover time impairs the functioning of the body. It disturbs the natural energyfield of the body causing stress, fatigue and weakening of the immune system,causes many headaches, problems with concentration, dizziness, depression, isoften the trigger of seizures, insomnia, high blood pressure, infertility, andso on.
Childrenare particularly sensitive to wireless radiation signals because their nervoussystems are even more uplifting. The skulls are thinner and smaller, and theradiation penetrates deeper into their brain. Many schoolchildren have wirelesstechnology, but this has a negative impact on children’s learning ability.
InMay 2011, the World Health Organization recognized that wireless technology isa potential carcinogen HOW MUCH WIRELESSRADIATION IS HAZARDOUS Internationalstandards specify the allowed radio radiation. Namely, according to thestandard, a different amount of irradiation is permitted depending on whether aperson is in a controlled or uncontrolled environment. A controlled environmentis defined as a space where people’s access and stay can be controlled, wherepeople who are irradiated are staying aware and where special measures can betaken to reduce irritation. Uncontrolled environments are public places wherepeople’s stay can not be controlled, nor they should be aware that they are inthe radiation radiating zone, nor take any special protection measures.Weare interested in two 2.4 GHz frequency bands and 5.4 to 5.
8 GHz, which areused for various purposes of wireless communication, from cell phones,bluetooth devices, wireless telephony to wireless. For both of these ranges,the standard permits irradiation of 5mW / cm in 6 minutes in a controlledenvironment, or 1 mW / cm for 30 minutes in an uncontrolled environment. It isimportant to emphasize that this level of irradiation refers to the susceptiblyirradiated in the indicated time periods. If the irradiation is interrupted,the duration of the allowed irradiation increases in proportion to theirreversibility of the irradiation. (Heid,2016)However,we should always be careful when we are near the radio.
It should be avoided tostand the antenna radiation antenna, to hold the antenna hand whiletransmitting it or to hold it for a long time in its immediate vicinity or nearthe antenna cables. Home wireless devices do not emit sufficient energy that itcan be dangerous, but some other radio devices can have a much higher power ofthe transmitter.(Heid, 2016)WIRELESSTECHNOLOGY AS POSSIBLE CAUSES OF DISEASES Electronicdevices with wireless technology connect to wireless computer networks(wireless LAN) using electromagnetic radiation. They are installed in homes,schools, offices, shops, cafes, airports, libraries, hospitals, publicbuildings and entire parts of the city. Wireless signals, unlike TV and radiosignals, are strong enough to penetrate the concrete walls. Many healthcareprofessionals believe that wireless radiation is extremely dangerous forlong-term health.Manypublic health experts, on the basis of the existing science, believe that thereis a possibility that in the future we will face a tumor epidemic that will resultfrom uncontrolled use of mobile phones and an increased exposure of thepopulation to wireless devices.
It is therefore important that we all, and inparticular children, restrict the use of mobile phones, limit the exposure toback-level wireless technology, and that the government and the industrydisclose ways to enable us to use wireless technology without such high riskfor serious diseases. We must educate decision makers that the usual businessis unacceptable. The importance of this public health issue should not beunderestimated.(RSA and Ga,2016)Sincethis is still somehow a new technology, studies on long-term effects on healthhave not been performed. However, thousands of studies have been carried out onthe health effects of mobile phones and telephone transmitters. These studieshave found that radiation that is spread by mobile phones can cause cancer.
Issuesrelated to fertility and abortion are of great concern to researchers who arestudying EMF in schools. Only a handful of studies investigated the possiblerelationship between exposure to EMF (electromagnetic frequency) and the riskof abortion.Wirelessradiation penetrates into the body, affects cell membranes and cells, and thusover time impairs the functioning of the body. It disturbs the natural energyfield of the body causing stress, fatigue and weakening of the immune system.Itcan also cause headaches, problems with concentration, dizziness, anxiety,memory loss, depression, hyperactivity, abnormal heart rhythm, epilepsy, nausea,skin rash, insomnia, tinnitus, high blood pressure, brain damage, autism,diabetes, fibromyalgia, infertility, DNA damage, leukemia, tumors, etc …
MOBILE PHONE ANDTHE IMPACT ON HEALTH Asa mobile phone emits electromagnetic radiation, there are authorities that warnthe recipients of negative consequences for the health of the user after a longperiod of use. Radiation is non-ionizing, but, however minimal, the probabilityof adverse effects exists. Many studies have shown that there is no significantlink between the use of mobile phones and human health, if it is used withinthe limits of short-term and normal daily use, but due to the extremely rapidincrease in the number of users, extensive surveys are being launched.(Naeem,2014)Today’sconsensus of scientific and medical associations is that the negative effect onthe health of users can not yet be established with certainty, given the smalltime period of massive use of mobile phones, which does not allow for asignificant statistical study. However, it is recommended that you do not useand keep the mobile phone close to your head or heart, especially childrenSCENIHR(Scientific Committee on Emerging and Newly Identified Health Risks) concludedin 2007. that there is no significant effect on human health from the radiationof mobile phones in normal use, ie that normal exposure to mobile phoneradiation can not cause brain cancer, neurological or reproductive effects, butsome non-exclusive studies suggest the viability of the benign tumor of theauditory nerve. CONCLUSION Manypublic health experts, on the basis of the existing science, believe that thereis a possibility that in the future we will face a tumor epidemic that willresult from uncontrolled use of mobile phones and an increased exposure of thepopulation to wireless devices.
It is therefore important that we all, and inparticular children, restrict the use of mobile phones, limit the exposure toback-level wireless technology, and that the government and the industrydisclose ways to enable us to use wireless technology without such high risk ofserious illness. We must educate decision makers that the usual business isunacceptable. The importance of this public health issue should not beunderestimated.Thereis no space in which a person works, lives or sleeps, and in which there is noharmful radiation. Wireless technology refers to the transmission ofinformation between two or more points that are not physically linked. Itsorigin dates back 200 years ago.
SAR represents the amount of energy that thebody absorbs during exposure to electromagnetic radiation. In other words, itis the power of an EM wave that is absorbed by a certain mass of human tissue.When it comes to radiating the mobile phone, SAR represents the maximum powerper unit mass absorbed by the head of the phone user at a certain time.(Naeem,2014)Electromagneticradiation is a combination of oscillating electric and magnetic fields thattravel together through space in the form of mutually vertical waves. Theradiation intensity of the mobile phone is different at different stages of theconnection. The most intense radiation is in the reporting stage and decreasesduring the conversation phase.
Therefore, it is recommended that the mobile phonecomes to a close only after the connection is established. Theradiation level at the permissible limit exists at a distance of 5.6 cm fromthe antenna for controlled conditions and 10.5 cm for uncontrolled conditions.It is obvious that level and radiation are far-eminent than allowed. Inaddition, people should not be so close to the source of radiation that, inreal terms, these levels are much lower than the one we considered.
However,we should always be careful when we are near the radio. It should be avoided tostand in the antenna radiation beam, to hold the antenna with the hand whiletransmitting it or to hold it for a long time in its immediate vicinity or nearthe antenna cables. Home wireless devices do not emit enough energy to bedangerous, but some other radio devices can have a much higher power of thetransmitter.
