mastermunj 10 Report post Posted May 26, 2011 Hi All, Our society has MTNL / Dolphin cellular towers as of now and they are giving barely any rent which is not much beneficial to society. We are now planning to approach other cellular operators like Airtel, Reliance, Vodafone & others to know if they can place towers on our society terrace and would give better rents. Can anyone guide me through this or give suggestions about how to proceed ahead on this matter. Thanks, Munjal Share this post Link to post Share on other sites

mastermunj 10 Report post Posted May 26, 2011 Radiation exposure is everywhere. I went on my terrace and looked around to see more than 30 towers within 1 square kilometer area approximately. Share this post Link to post Share on other sites
prakashkadam 1 Report post Posted May 27, 2011 Radiation exposure is everywhere. I went on my terrace and looked around to see more than 30 towers within 1 square kilometer area approximately. Among the health concerns related to exposure to cell towers are: Abnormal cell growth promotion DNA damage Reduced immune system competence Sleeplessness, irritability, anxiety, depression Weakened blood-brain barrier Childhood and adult leukemia Eye cancer Infertility and miscarriage Attention span deficit and general memory loss Sleep disturbance and chronic fatigue Brain tumors Cardiac problems 1 Share this post Link to post Share on other sites
santanu@impaq 16 Report post Posted May 27, 2011 The RF power output of the Radio Units in Urban GSM config are nowadays limited to 40Watts per channel. If you are more than 10 meters away from an antenna, the ill effects are not apparent as per varoius studies. BUT !!! What do you say about putting a 2 Watt ( that is GSM Max ) transmitter right on your head barely a few milimeter from your brain. Mind you, even if you disregard the radiation , it is also a small local microwave heater on your head. Just kidding ! Lets enjoy the friuts of the cellphone revolution. RADIATION IS EVERYWHERE!

raccoon 53 Report post Posted May 27, 2011 RADIATION IS EVERYWHERE - a very, very dangerous statement. So are poisons, so are carcinogens and a lot of other things. But that does not mean you can get away by saying that and ingesting a poison beyond a limit. And we hardly even know what those limits are... Disrespect it at your own peril.

sougatadc 358 Report post Posted May 27, 2011 a la handset radiation limit (SAR), do the operators observe radiation limit of the antennae fixed on the towers? And nowadays, the probability of hazard has shoot up as number of operators have gone up considerably and every operator has antennae around you. Nobody is happy if the signal is poor, so the operators tend to keep the signal high which makes the radiation more. There are so many voice/data signals omnipresent (BSNL mobile,EVDO/1X, 3G; Vodafone; AirTel, Aircel, Uninor; TataIndicom; Virgin; Tata DoCoMo; Reliance GSM; Reliance CDMA; Netconnect/1X; MTS; !dea), many operators are sharing the same towers, it is highly necessary to have ombudsman for radiation from towers also.

santanu@impaq 16 Report post Posted June 22, 2011 More the number of towers per operator , less is the power output per radio unit since the tower get closer to each other and to prevent cross-talk, the transmitter power at tower has to be reduced. But as you rightly pointed out, there is no proper audit of the resultant radio energy spillage by the operators. The operator are supposed to self audit but since we have been closely associated with Indus, I can assure you that the situation is far from being under control. The only consolation is that RF power in the region upto 5Ghz is non-ionizing in nature and does not cause molecular level damage to living cells. Another example in Delhi, Pitampura tower has 2 nos of 10KW transmitters and 1 no of 5KW transmitter for TV and radio. These power are hugh as compared to a few hundred watts for a heavily loaded multi operator tower. Such High power transmitters for Radio and TV exist in almost every major city. This RF radiation is very different from ionizing radiation caused by alfa , beta particles as in case of nuclear fission or fusion radiation which damages at a molecular level causing severe damage to living cells. The cellphone is a necessary evil. The GSM handsets are a bit better because they transmit at lower power than an average CDMA handset. That too is because CDMA operators can get away with 1/6 th the no of towers needed by GSM operators for approx same subscriber density. So a CDMA tower is usually much far away causing the handset to operate at a higher power levels and consequently lesser batt backup. But then CDMA is a better technology as far as spectrum utilization, multipath interference, call quality with EVRC-B etc. Share this post Link to post Share on other sites
drabhayshah76 7 Report post Posted June 22, 2011 Well, i heard that a CDMA handset transmits 10 times less power than a GSM handset.

digitalnirvana 646 Report post Posted June 22, 2011 (edited) ^ CDMA uses more power please read http://en.wikipedia.org/wiki/Comparison_of_mobile_phone_standards . Edited June 22, 2011 by dipanlahiri Share this post Link to post Share on other sites
santanu@impaq 16 Report post Posted June 22, 2011 To accomodate more subscribers with limited spectrum, the GSM networks need to reuse the frequencies by installing more towers per area. As a result the Tower is closer to the handset and the handset needs lees power to make its signals reach the base station. CDMA need only as may towers to just make sure that the signals do reach the hanset and vice-versa. So by default CDMA requires much less no of Towers for the same subscriber base. Since the Tower is further away, the handset is forced to use higher power levels to make sure the signals reach base. Moreover as dipan also mentioned above, inherently CDMA handset radio consumes more power. But the earlier question of Audit of Radiated power from Towers of various operator remains unanswered. Hope the operators stick to their audit deadlines. Share this post Link to post Share on other sites

csmart 472 Report post Posted June 23, 2011 for few bucks, we are ignoring long term health hazards that these towers pose. in western countries, people fight to drive out towers from their neighborhood while we fight to get the towers right on top of us. besides, there, towers are much higher then at ours. its pity that people don't realize how harmful these are to infants just for few bucks. we also do not estimate the effects of weight of these towers on building. we simply want more money.

city02 63 Report post Posted June 24, 2011 for few bucks, we are ignoring long term health hazards that these towers pose. in western countries, people fight to drive out towers from ... i agree but the bigger issue is that there are much greater health hazards that are also ignored in india so why should this one be any different? how many have died due to exposure to towers? yet everyday people are killed crossing tracks in mumbai alone just to save 1-2 minutes of climbing stairs how many have been hospitalised due to towers? yet millions smoke and get various types of cancer despite any govt efforts to date, our cities remain among the world's dirtiest for air, water, and sound pollution which kill or injure lakhs of city dwellers... the list is endless and the risk from towers to your health while certainly there on an absolute scale is not even in the top dozen risks that we face on a daily basis and calmly accept with our 'chalta hai' attitude i'm not implying we should mount towers on every rooftop but rather even if we did, it would not be able to rise to the top of health hazards we face routinely in metros 'we are like this only' ... but i think most of you knew that implicitly.

csmart 472 Report post Posted June 24, 2011 i agree that cities in India are not safe. but at the same time, everybody takes some or other way of protecting themselves. for water, you haver water purifier in home, you dont keep your house tardy. one of the reason for dirt in cities are we, citizens. we keep our house/office clean and in the process dump everything on road. you do not spit in your house but you do on roads. similarly, govt. is educating people on rail tracks crossing. but then we do not want to listen. for us whatever we do is right and govt is wrong. look at the way we cross the road, we never wait for signal but follow our own methods. you are in mumbai, so you how dangerous it is on Marine drive and PAlm Beach Road to cross and walk. the former has few signals but we cross wherever we feel like. while palm beach road is not meant for walker/joggers, still people do. now what govt do when we do not want to improve. similar with seat belts and helmets. we will follow all the rules religiously when we travel abroad and while in India, breaking rules is our birth right. you are aware of hazards related to cell towers. but since others are doing it, you also want it. there is no data that can identify that cancer is caused due to cell tower or how many hospitalized. it affects child development cycle. why dont you remove water filter from your house? you will not do it as you know it will affect you. the point was to highlight hazards and now its upto you what you want to do. the attitude you showed is what every Indian shows. and then blame govt when anything goes wrong. i am not saying govt is right or doing everything they can. we are also not doing what we can do.
