In the age of Cellular Mobile technology telecom industries are growing very fast due to its demand, every year large number of users are using the mobile Phones this forces companies to provide the coverage to there customers in a very discipline manner ,In order to provide the coverage companies have competition to install new cell site, now a days we can see new cell sites around us ,you can see large number of towers are installed on the building, due to this a net of towers are created around us , these tower are highly radiative which are radiating the EMF(Electromagnetic Magnetic Field wave), At some range it is harmful for the human body .In this competitions companies are neglecting the rules and regulation of the TRAI(Telecom Regularity Authority of India ),which causes harmful effect to the human being .TRAI have some set of rules on basis of which companies have to installed the tower, and the transmission from the tower should have a specifics range of EIRP(Effective Isotropic Radiated Power).Government is responsible to check the EIRP ,for this government asked companies to provide the report to the TRAI .The survey perform by the companies to provide this report to the TRAI is called EMF Survey (Electromagnetic Field Survey).EMF Survey is perform to check the value of EIRP across the BSS.

Time Is Almighty EMF SURVEYTempus Telcosys (P) Limited Page 2IntroductionIn the age of Cellular Mobile technology telecom industries are growing very fast due to itsdemand, every year large number of users are using the mobile Phones this forces companiesto provide the coverage to there customers in a very discipline manner ,In order to provide thecoverage companies have competition to install new cell site, now a days we can see new cellsites around us ,you can see large number of towers are installed on the building, due to this anet of towers are created around us , these tower are highly radiative which are radiating theEMF(Electromagnetic Magnetic Field wave), At some range it is harmful for the human body.In this competitions companies are neglecting the rules and regulation of the TRAI(TelecomRegularity Authority of India ),which causes harmful effect to the human being .TRAI have someset of rules on basis of which companies have to installed the tower, and the transmission fromthe tower should have a specifics range of EIRP(Effective Isotropic RadiatedPower).Government is responsible to check the EIRP ,for this government asked companies toprovide the report to the TRAI .The survey perform by the companies to provide this report tothe TRAI is called EMF Survey (Electromagnetic Field Survey).EMF Survey is perform to checkthe value of EIRP across the BSS.DefinitionEMF Survey is perform to collect the EIRP (Effected Isotropic Radiated Power) ratio to knowabout the strength of EMF signal across the BSS (Base Station Subsystem).Need Of EMF SurveyThis survey is performed to check the harmful effect cause due the high power radiation of theEMF from the towers.
  • 3. Time Is Almighty EMF SURVEYTempus Telcosys (P) Limited Page 3TRAI Guidelines:Old Guideline: According to the TRAI (Telecom Regularity Authority of India) the survey area across thenominal point should be of 20 meter. EIRP ratio (Effective Isotropic Radiated Power): According to TRAI the EIRP ratio shouldbe less than 1.New Guideline: According to the TRAI (Telecom Regularity Authority of India) the survey area across thenominal point should be of 60 meter. EIRP ratio (Effective Isotropic Radiated Power): According to TRAI the EIRP ratio shouldbe less than 0.5.EMF Survey Tool Kit:1. GPS2. Laptop3. Digital Camera4. Magnetic Compass5. Measuring Tape6. Binocular7. Writing material8. EMF Tester/EMF Meter/Spectrometer

Time Is Almighty EMF SURVEYTempus Telcosys (P) Limited Page 4Procedures of EMF Survey With the help of GPS we have to reach at the nominal point. Collection of data :o Site Ido Site Nameo Site Addo Lat, Longo Antenna Heighto Tower Heighto RF cable lengtho panoramic photos (0,30,90.120……..330 degree) 12 photos, sky should be 10% &Cluster 90%.o Calculate Firing angle/azimuth angle.o Sector Photos(Sector A, Sector B, Sector C)/o Site Photoo To take adjacent photo if the G+1 building is present in the range of 60 meter.o Detail of each G+1 building and cell site is Mandatory.Calculation Method: There are two methods to calculate EIRP Ratio :o Using EMF Tester ando Using calculation sheet( Formulated excel sheet).
