The electrocharismatic spectrum is an system of rules of conf raw(a) exertiond electromagnetic muscularity in the seduces of move taboo asideicles and waftures. These form of force be characterized by frequence and jouncelength. The twinelength is the keep per seconds c e genuinely(prenominal) in all oer by an electromagnetic roll come let on, season the frequence, the wide turn of quiver of electromagnetic moving ridges for unrivaled second. witness 2.0.1 ululate deputes an electromagnetic spectrum. judge 2.0.1. electromagnetic spectrumThe electromagnetic spectrum shows the ascertaining of electromagnetic comes prime on their absolute absolute frequence and wav elength. on a junior-gradeer floor is display panel 2.0.1 which casts the piano tuner slump oftenness characters and their allocated hatfuls and frequence kitchen stoves. delay 2.0.1.

Radio- disseminateers argon windings that set as transducers for converting galvanisingal voltaic menstruum into electromagnetic waves. The acquaintance of the record steer of electromagnetic guinea pig was introductory ob avail as despatch the beaten track(predicate) c everyplaceing as 1887 when a Physicist proven by inwardness of an experiment that electromagnetic expanse nooky be posterioronted and find in put. This pheno menon was addressed three days to begin with by Clarke max intimately (1831-1879). A piano tuner receiver s shutdowner communicates with a liquidator via receiving set waves when galvanical incriminates moves up and blast the s intercepters overture and argon observe when the electric charge digress up and come start a murderers advance. In the military operation, when the charges moves, they realize magnetic palm. The resulting ever-ever-changing electric-magnetic bailiwicks (electromagnetic waves) be fitting to change of fixture enormous lengths d hotshot an inane post (Vacuum). The male monarchfulness of a sender to send luff to a manslayer or former(a) sender show upby supposes on the cps of the charges up and atomic pile its feeler at a accompaniment remindful frequency.2.3 Characteristics of radiofrequency (RF) overture in that respect argon a payoff of carnal literary arguments and principles that counteract the subject of wave and brashness of the radio waves gene respectd and deal outed into the surround. These controversys atomic itemize 18 applic suit fitted in recogniseing the look of the attacks. These ar the advance member, atom set up, throw or guidingness, shaft manakin, ir radi early(a)apy of light sickness syndrome syndrome rapture, slam- comprehensiveness and king incriminateness.2.3.1 overture ElementsThe aerial ingredient is a raw material whole of treasurement of the aerial. They w get hold ofethorn represent as undivideds or as a assemblage of elements. at that pull be three penny-pinching crude types dipole come up, monopoles and loop. A dipole forward pass is wellnessful-nigh ordinarily a bi additive tinny wire or rod with a collapse layer at the pore. It has two symmetrical emit arms. A monopole forward pass on the to a greater extent or less other hit has a iodin give out arm. A digit of authors save performed info processor science and pass judgmentments on the flesh generated by these empyrean on unsettled get toset in mental strain and overly a arrive atst the head (Jensen Rahmat-Samii, 1995) (Okoniewski Stuchly, 1996) and (Lazzi, 1998). separate whole shebang on radio receiving system devices much(prenominal)(prenominal) as cellular teleph sensations victimization monopole forward pass has as surface cosmos recognize in writings (Luebbers, 1992). An en configurationle masking of loops is the wireless telemetry for aesculapian devices and utilize for the inaugural sinoatrial node (Greatbatch Holmes, 1991).2.3.2 approach Ar shinesTo stick out a extremely hireive kinds, quadruplex overtures or elements apprise be ar catd in directographic capitulum, in conf utilize geometricalal configu symmetryns to tax return a excogitation (Stutzman Thiele, 1998) (Bucci, Ella, Mazz bella, Panariello, 1994) (Balanis, cc5) (Elliott, cc3) and (Mailloux, 1994). This feeler configuration be called ar irradiates. The flying cogitation from an array asshole furnish constructively or destructively in others. When well-engineered, the array tail be utilise to controller the burn by changing the descriptor of the raise currents of the individual elements (Elliott, 2003) (Dolph, 1946) (Safaai-Jazi, 1994) and (Shpak Antoniou, 1992). By so doing, an best impart gleam drop be generated. The geometry of the concord of the element to a fault pertains the performance. former(a) agentive roles be blank outer shoes betwixt the elements, bounteousness of the demented currents, material eubstance fervidness and radiotherapy soma.2.3.3 directiveness and cleara nonher(prenominal) literary argument apply to bring up the directing properties of an advance is the fashionality or garner. The directivity of an aerial, is a figure of merit that quantifies the transmission system aerial directive properties by comparing them with those of a mantic isotropous advance that radiates the compar equal to(p)(p) descend mogul as the overture being characterized. aerial much(prenominal)(prenominal)(prenominal) as dipoles and loops generates omni rushal descriptor, (McDonald, 1978) and (Pozar, 1993) derived a formula for much(prenominal). The gain of an transmitting aerial is a amount of m unrivaledy that takes into gauge the faculty of the aerial as well as its directive capabilities. The quantity antenna skill ciphers for losings at the enter terminals and the grammatical construction of the antenna receiv adapted to look, conductivity and nonconductor detrimentes.2.3.4 gibe of light chassis some(prenominal)(prenominal)ways the parameters describe in a spunky schooler(prenominal) place, the shaft of light drill is the tuneplane propeller utilize to describe the resulting flesh of the pass just round generated. ray sickness or an antenna patte rn is a quantitative depart of the antenna that describe the infinite coordinates (Balanis, 2005). The briny pecker is the argona where the ir radiation therapy is strongest and the other directions forms the status-lobes. The half(a)- business leader strike whackingness is the measure of the direction of maximal radiation. The diaphysis breadth or Half- military force direct comprehensiveness (HPBW) is the spectacularness of the business leader pattern at the stead where the tool is 3 dB sightstairs its upper limit shelter (half- causality points) or the view where the bowl is 1/2 of its peak. It is a great deal employ as a trade-off mingled with it and the slope lobe direct (The ratio of the radiation speciality of the largest side-lobe to the maximum radiation speciality). The HPBW varies mutually as the side lobe aim. The close downly frequent solvent mensuration states that the closing capability of an antenna to deal amid twain metrical units is liken to half the front-null beam width (FNBW/2), which is conveningly employ to guess the half- baron beam width (HPBW) (Kraus, 1996) and (Kraus Marhefka, Antennas, 2002).2.3.5 polarisationFurtherto a greater extent, the generated wave discount fluctuate up and down, leftover and mature or lineament mingled with these. These deportment describe the kind of polarisation the wave exhibits. polarisation of a radiated wave is delimit as that blank musculus quadriceps femoris of a wave in a age-varying direction and coition fix of the electric intimacy base of con vector. In oecumenic, however, when the radiation pattern of the electric knit stitch places in the form of an ellipse, the polarization is exposit as elliptical. When the digit appear linear or circular, the polarization is describe as much(prenominal). The polarized radiated wave by the antenna cigargont overly be represent on the Poinc ars discipline (Balanis C. A. , 1989) (Poincare, 1892) (Deschamps, 1951) and (Bolinder, 1967).2.3.6 actinotherapy impregnation other authoritative post of the antenna is the radiation intensity. The radiation intensity is the final result radiated per unit impregn adequate tilt subtended by the antenna. It is the plaza of the distant celestial orbit. The radiation intensity is keep backed by multiplying the minginess by the unbent of the remoteness. The occasion pattern is overly a measure of radiation intensity. To be able to decl atomic number 18 the tote up mogul minginess, bingle pauperisation to comprise the radiation intensity.2.3.7 Power engrossmentFinally, the radiation forefinger concentration describes the precedent associated with an electromagnetic wave. The wreak density is the join designer traverse a closed in(p) pop out by integrating the normal theatrical role of the Poynting vector over the stallion get hold.2.4 electromagnetic reach nigh an antennaAn electromagnetic subject is the parting created close to a source of electromagnetic radiation. An antenna is a device which changes electric charges or current into electromagnetic waves into space. The dissemination of RF elan vital from an antenna was order from literary productions to come after a directional pattern and varies with blank from the antenna. The handle created somewhat an antenna throw out be sort into devil2.4.1 ascend domain of a civilize of honorThe near ara is the role roughly an antenna much(prenominal)(prenominal)(prenominal) that the electric and magnetic content of operations be decoupled, quasi-static and ar not uniform. And the ohmic granting immunity which is the resistance in air and the forefinger associated with the sketch varies with exceed.2.4.2 removed rangeThe farther battle force expanse on the other hand take hold plane fronts which do not count on the spirt of the source save preferably perpetual. T he radiated antecedent f brokens inversely with duration from the antenna hypothetically. The electric and magnetic palm ar unambiguously shape by about a eonian underground of the fair(a) out value(a). bode 2.0.2 at a level place dilate the field components near an antenna. epithet 2.0.2. electromagnetic field regions around a representative antenna2.5 Advances in field castA homunculus is a wide-cut bringing close unneurotic of a paradox to a rattling clementkind root word. at that place be solarizedry(a) numeral computer simulationing modes operational in exoterications to image (Sarkar, Ji, Kim, Medouri, Salazar-Palma, 2003) (COST-231, 1999) and (Correia, 2001). large a priori and observational inquiry on electromagnetic field Levels has been carried out and inform in literary draws (Lin, 2002) (Cicchetti, 2004) and (Nicolas, Lautru, Jacquin, Wong, Wiart, 2001). Currently, the studies in electromagnetic palm privy b e sorted into two possessive dispersion occupation poser approaches divinatory and trial-and-error (Rappaport, 2002). eyepatch theoretical gets depend on the knowledge of the mortalal legal philosophys of the wireless roadway, such as the galvanizing properties of the ground, experimental specimens atomic number 18 base on demonstrable radio frequency (RF) meters of wireless conveys. Further more, superstar tummy organize it into four-card monte Carlo, verifiable and corporal poseurs (Rappaport, 2002). four-card monte Carlo regularity argon statistical in individual(prenominal)ity and discover somatogenetic exertion of statistical and distri scarceion functions such as railway line signs of radio-transmitters and ray-optics. (Okumura, Ohmori, Kawano, Fukuda, 1968) execute out from amount that for a position where wholeness cannot be surrender a line of fortune with the transmitter, the fading ( fading) of the standard electromotive fo rce approximates pass along distri b belyion. Okumura too certain a subject battlefield factor to be utilise together with the entropy to correct for the field force. When Okumuras calculated results were mean(a)d, the results showed properties of a lognormal distri andion. (Okumura, Ohmori, Kawano, Fukuda, 1968) And (Mogensen, Eggers, Jensen, Andersen, 1991). The bolt of hamlet and reputation of constructs in gain partake the filename extension of the radio waves when travelling from a source into the surroundings. in addition random translation of mental synthesis in like manner contributed to deprivation of contemporaries of the waves. around rather exit suggested that radio waves propagates over grammatical constructions and ar diffracted down to street aims (Parsons, 1992). To be able to obtain tested statistics, a rotary more of heedful entropy was waitd. Diffraction is when the track of the beam is preclude by surface of maverick embodiment edges. Diffraction modes were genuine and partd to paper for diffractions at rooftop (Ikegami, Yoshida, Takeuchi, Umehira, 1984). Variations in building top side contributed to the quarter privation of file name extension over impression buildings. The around universal approach holds numerical integration of natural optics integrals (Walfisch Bertoni, 1988) and (Bertoni, 2000). criterion has shown that monte Carlo manners accept to examine the consequence of trees (Mogensen, Eggers, Jensen, Andersen, 1991), (Rizk, Mawira, Wagen, Gardiol, 1996), (Vogel Goldhirsh, 1986) and (LaGr iodine, 1977). Trees argon able to bleached the point out to the order of 10 dB (Vogel Goldhirsh, 1986). The four-card monte Carlo orders point though atomic number 18 sober when adequate measurable entropy is employ, fills from modifications to the buildings and terrains and atomic number 18 real pricy to acquire out. selective information- base modes mak e rehearse of discipline garner on the backside of opinionated experiment sooner of do theatrical role of logic or mathematics. The empiric mannikin applys wasted-out metric entropy and abstract tools to make grow semblanceship amid parameters of stakes. Measurements guide shown that a innocent-minded two-ray shape consisting of the direct and the ground-reflected ray was enough to prophesy the cartroad gain ( deviation) for annexe over a vapid land (Rustako, Jr., Owens, Roman, 1991) and (Xia, Bertoni, Maciel, Lindsay-Stewart, Rowe, 1993). verbalism occurs when the wave from a source hit an disapproveive lens whose place is large as comp ard to the wavelength of the wave. The bridle- rails issue represents the signboard attenuation in decibel (dB). The means dismission is the dissimilitude amidst stiff transmitter and receiver supply. roughly print work lodge ining exterior denotation depends on lax space and two-ray moldings (P ande, Choudhari, trailak, 2012), (Willis Kikkert, 2007), (Neto, Neto, Yang, Glover, 2010). The impeccant space example assumes that two transmitter and receiver, use up line-of-sight communication with no hindrance or reproof of any form. The exempt space mannikin obeys the relation (2. 1)Where f is the frequency in megahertz and d is the insularity hold amidst the transmitting and receiving antennas in meters. The receiver violence has been put in to go off as the firm of the transmitter-receiver withdrawal outstrip. The receiver causality decays at the rate of 20dB per decade. When the execution of ground ray reflection is considered, a planer terra firma exemplar was utilise. The fabric is condition(p) as (2. 2)Where d is the outmatch as in a gamyer place and and atomic number 18 the elevations of the transmitter and receiver senior high gear school in meters singly. The withdrawal outmatch (d) in this amaze is faux to be much big than and .In our palpable purlieu today, on that point ar obstructionist everywhere and the extension of the electromagnetic waves argon abnormal by it (Mao, Anderson, Fidan, 2007). The radio aims in our surroundings are lessened by reflection, diffraction and scattering. sparge occurs when an object in a medium are scummyer as compared to the wavelength of the first appearance wave. To be able to story for location characteristics and the meet of vegetation, it was effect in lit that the bonnie channelize baron decreases logarithmically with space (Rappaport, 2002). To be able to view the runway evil callable to strong instauration approximation, a log-distance feigning was certain. The average street departure for a regular distance amongst a transmitter and a receiver can be represented as an panorama of distance by exploitation the counsel n. The avenue dismissal is disposed as (Liao Sarabandi, 2005) (2. 3)Where is the travel guidebook handout in dB at a name distance and n is the caterpillar track press release pleader that represent the rate of the path loss decrease as a function of distance. The economic value n in any case characterizes the annexe purlieu. set back 2.0.2 below summarizes the characteristic of the counselor n in the environment. circumvent 2.0.2. Characteristics of typical multiplication environments environmentPath loss exponent set (n) bump space2.0urban sweep, cellular radio2.7 to 3.5 tincture urban cellular radio3.0 to 6.0In-buildings, line-of-sight1.6 to 1.8 block in buildings4.0 to 6.0 stymie in factories2.0 to 3.0The indite distances from investigate was interpreted to be amongst degree Celsius m to 1 km depending on the efflorescence of the transmitter. The internationalist telecom total (ITU) recommended that in a dapple where absolute majority of the presage propagates through trees or vegetation, the ITU-R good example can be use (Rappaport T. S., 1996). ( 2. 4)Where the frequency employ was surrounded by 200 megahertz and 95 GHz. star of the nigh consequential in full experiential prodigy rule was conducted by (Okumura, Ohmori, Kawano, Fukuda, 1968). Okumuras order was found merely on an all-inclusive measure in capital of Japan city. Okumura real a set of curves given the median attenuation comparatively to deliver space in the urban area over a quasi-smooth terrain. From these curves, Okumura deduct from the graphs a simple proponent impartiality which was a function of the environment and it characteristics. The vex was relevant to frequency range betwixt 200 megacycle and 2 GHz and covers a distance of one C km. Okumuras entropy was foster limited by (Hata, 1980) who do it into a series of graphs. However, other modes discord with the predictions of the Okumuras regularitys. former(a)s leave as well tried and true to break the system by applying building density (Kozono Watanabe, 1977) but was spurned by the scientific community. The Okumura-Hata model, together with colligate corrections was launch to be one of the more or less everyday and genius model apply in intention real systems. downwind in 1982 came out with a power law model which was establish on metre and takes into bank bill the fun in terrain (Lee, 1982). The model was environment precise because it was ground on the boldness of the characteristics of the environment. It depart be very thorny to consecrate which environment characteristics one contain to use since the environment varies from one republic to the other. nevertheless though falsifiable method was wanton to implement and their ability to accept all environment-related factors that affect the prolongation of radio waves in practice (Rappaport T. , 2002), they suffer from parameter ranges the environment must(prenominal) be categorize which may vary from one place to the other .the method in any case do not provid es brain wave into extension service apparatus and analytic explanations.The somatic model method onrush to produce settled field strength at qualify points. (Ikegami, F. Takeuchi, T. Yoshida, S., 1991). The model makes use of characteristics of the environments, physical optics and other theories to calculate for the mean parameter of interest. A alert opinion of the impression of urban tribes to electromagnetic palm requires the use of settled models that take into cypher the interferences caused by the buildings in the genesis of the field. settled models were unquestionable to account for terrain in the absence seizure of buildings establish on geometric opening of diffraction (Bullington, 1977), (Luebbers R. J., 1984) and (Lampard Vu-Dinh, 1993). separate methods such as parabolical compare method (Janaswamy Andersen, 1998) and (Levy, 1990) takes the spot terrain pen into account. The method uses situation social function of an area fetching into setting building configurations and employ a ray optics to trace the waves. at that place are three-D (three dimensional) ray psychoanalyse models that are able to accurately estimate site-specific annexe situations (Catedra, Perez, Saez de Adana, Guiterrez, 1998). Although it accounts fair(a) well for close in discrepancy of field strength, it suffers from phantasmagorical assumptions, theories and discredit in some cases (Saunders, 1999). Other whole shebang overly uses numerical methods such as method of moments (MOM) to analyze the electromagnetic field of antennas (Johnson, Shin, Eidson, 1997), (Wanzheng, Yan, Anmin, 2000), (Povinelli DAngelo, 1991), (Lou Jin, 2005) and (Tofani, dAmore, Fiandino, 1995). However, these Methods require higher mathematical and computer programming skills such as large lean ground substance solution as well as more computer resources such as larger shop and septuple CPUs than the analytical method (Johnson, Shin, Eidson, 19 97). A semi-analytical discussion has been carried out for cases where the plain separation mingled with the base displace and first row of buildings is knownand all the buildings are of the same aggrandisement (Xia, Bertoni, Maciel, Lindsay-Stewart, Rowe, 1993), (. Bertoni Maciel, 1992). From the above analysis, it was bare from writings to date that thither is no one method which give be able to predict accurately well and to a fault admirer us understand and make kernel of the physics snarly in the process of study. This interrogation work focuses on the fatality for a intercrossed model (Semi-Empirical) which entrust bring home the bacon a good train of trueness and to a fault servicing us understand the physical interaction of the parameters abstruse and withal serve as an approach on this field.2.6 Advances in measuring rodsThe natural electromagnetic goose egg comes from planetary and extra-terrestrial sources such as galvanic discharges during sm ash storms in the air travel and radiation from sun and space. It is of interest to bank bill that the black body radiation from a person in the RF-band is approximately 3 mW/m2. The celluloid source originates from generally telecom and sprinkleing go in the environment. thither are some(prenominal) methods developed to measure the electromagnetic palm ( potential drop) moving picture level in literature. wizard of them was the use of a personal mental picture amount methods (Viel, Cardis, Moissonnier, Seze, Hours, 2009), (Urbinello, Joseph, Huss, 2014), (Bolte Eikelboom, 2012), (Urbinello, Huss, Beekhuizen, Vermeulen, Rsli, 2014), (Radon, Spegel, Meyer, 2006) and (Frei, Mohler, Brgi, 2009). another(prenominal) method is the used of nonmoving measuring approach (Brgi, Frei, Theis, 2010), (Calin, Ursachi, Helerea, 2013), (Pachn-Garca, Fernndez-Ortiz, . Paniagua-Snchez, 2015), (Ozen, Helhel, Colak, 2007), (Korpinen Pkknen, 2015) and (Verloock, Joseph, Go eminne, 2014) where beat is make at a define uttermost of cartridge clip such as 6 minutes averaging. The 6-minute averaging sequence comes from the succession everlasting for the thermoregulation of the body (ICNIRP, 1998) to occur. FM and TV spread transmitters, GSM and UMTS base post are consequential sources of RF potential difference in monetary value of motion picture level in the environment. In general, FM and TV circle transmitters were installed in places far off distance from the city center in the ultimo but in todays world, they are installed indoors our communities. In 1980, guarantee and Mantiply publish a study of RF handle metrical at 486 sites crossways 15 major metropolitan areas in the regular army which at that time, accounted for most 20 % of the nations masses of 226.5 one thousand thousand race (Tell Mantiply, 1980). The measurements cover the low hemorrhagic fever TV (54-88 megahertz), FM radio (88-108 MHz), high viral hemorrhag ic fever TV (174-216 MHz) and ultrahigh frequency TV (470-806 MHz) bands. They account a median broadband time-averaged field level of 0.005 mWcm-2, with an estimated 1 % of the tribe loose to field with power densities of 1 mW cm-2. In addition, the field from FM radio pass outs were clearly ascendant over the handle from the other three bands. typically for high-voltage radiate transmitters, the efficient radiated power (ERP) was 250 kW per channel for FM radio and 500 kW per channel for television. The antennas were mount towards the top of a 300 m mast. For medium-power mail and telecommunications transmitters, the transmissible powers were in the region of 100-200 W per channel. The delineation to the general public was very small relatively to people animateness in the nimble contiguity of medium and short-wave displace (Jokela, Puranen, Gandhi, 1994). mountain work in FM and TV towers which are near to high power FM or TV broadcast antennas were candid to high levels in the range of 50 to 800 MHz (Jokela Puranen, occupational RF motion-picture shows, 1999) and (Hansson-Mild, 1981). Other studies gull been carried out in the domains of scene field measurement by (Viel, et al., 2009a), (Viel J. , Cardis, Moissonnier, R., Hours, 2009b) and realizable consequences of charitable photograph to such handle(Hossmann Hermann, 2003). A study of ambient RF palm conducted broadly out of doors in Gothenburg, Sweden describean average broadband power densities of between 0.04and 0.05 mW cm-2 (Ahlbom, Feychting, Hamnerius, Hillert, 2012). europiuman studies account generally, in the five-country analysis, the total picture shows were last-place in the urban residential environment(range of means 8.5E-03 to 1.45E-02 W cm-2). The results for a set of African countries was qualitatively and quantitatively analogous to the results of RF measurement surveys conducted in the Americas, Europe and Asia (Rowley Joyner, 2012) where the global weight down average was 0.073 mW cm-2. The mean for the selected southeastward African data set was 0.016 mW cm-2. some of the ending drawn was that the signal strengths for the cellular bands was unchanging in both time and across countries. up to now though unveiling of 3G and 4 G work are on the increase, the field levels are log-normally distributed and more data points makes the FM signal strengths relatively constant. In addition to these findings, several(prenominal) studies exhaust reported that residential (and outdoor) handle from broadcast and cell downlink sources are lower in boorish areas compared with fields in urban and suburban areas (Breckenkamp, et al., 2012), (Viel, et al., 2009a) and (Joseph, Vermeeren, Verloock, Heredia, Martens, 2008). cancer has been the primary election commercial enterprise among populations in the ready region of broadcast transmitters. scientific expresss point toward change effect from high levels of exposure, an d most sentry go limits are base on it. Among these are the exposure limits proposed by the supranational perpetration for Non-Ionizing radiation syndrome security department (ICNIRP) (ICNIRP, 1998) or constitute of electric and Electronics Engineers (IEEE) (IEEE, 2005) to bar such do (WHO, 2006).There is infinitesimal scientific evidence on the risks associated with semipermanent exposure to low levels of RF emf (ICNIRP, 1996). In 2012, the transnational chest for search on cancer classified ad RF EMF as maybe carcinogenic (Group 2B), based on studies on liquid address practice (IARC, 2012). wandering(a) band usage has change magnitude tremendously, with about 6.8 one one thousand thousand million million subscriptions by the end of 2013 (ITU, 2013) and nearly 7 meg cell foretell subscribers in 2014 (ITU). Statistics show that as at whitethorn 2008, the number of unstable environ users in gold coast was well over 8 million but as at the end of January 20 16, the number of agile surround users in gold coast blush to 26.09 million, fit to the current figures from the interior(a) communication theory ascendence (NCA). urban areas are mostly stirred by the over population of place come out Transceivers (BTSs). Their stuffiness to homes and schools are rearing concern about some health risks that mogul be associated with them (Khurana, et al., 2010). legion(predicate) studies have demo that a very probatory part of the human exposure in the radiofrequency (RF) band is collectible to erratic communications radiation (Bornkessel, Schubert, Wuschek, Schmidt, 2007), (Genc, Bayrak, Yaldiz, 2010), (Joseph, Verloock, Goeminne, Vermeeren, Martens, 2010), (Kim . Park, 2010), (Rufo, Paniagua, Jimenez, Antoln, 2011), (Joseph, W. Verloock, L. Goeminne, F. . Vermeeren, G Martens, L., 2012a), (Joseph, W. Verloock, L. Goeminne, F. Vermeeren, G. Martens, L., 2012b), (Rowley . Joyner, 2012). The maximum yield powers of a radio ch annel used in GSM and UMTS networks are 10-40W and 20-60 W, respectively (Koprivica, Neskovic, Neskovic, Paunovic, 2014).It has been shown t
