Reason why we should choose CDMA instead of GSM

Not long ago the International Agency for Research on Cancer which is a branch of the World Health Organization states that cell phone radiation "probably carcinogenic to humans". Scientific evidence of links between cell phone use to brain cancer stage has not reached a conclusion, said the agency, but there is some evidence that higher rates of brain cancer in people exposed to more phones. Mobile phone users should take precautions until the link obtained a definitive answer.

related to radiation, there are interesting suggestions from Joel Moskowits. "Switch to the previous CDMA network if your GSM network users!" What is the reason?

Apparently, the GSM mobile phone emits more radiation than mobile phones on CDMA networks. It is not revealed in the specification of cell phones because the phone company only lists "specific absorption rate" (SAR). "The figure could be misleading because the SAR measures the maximum radiation emitted phone and do not reflect the average amount of radiation emitted," says Moskowitz.

Several recent studies indicate that the CDMA phones normally emit some radiation output part of their maximum, while GSM phones emit half of the maximum value. This is related to differences in wave radio frequency (RF), which operated both networks, and the difference of the two methods of transmitting the cell phone.
When the GSM transmitting, the full power immediately. Then a controller circuit lowered it to an acceptable level of humans. Unlike the CDMA network which divides the frequency by the same among all the phone calls so the phone emits power at the lowest level necessary to maintain the accuracy of the call. Like someone who speaks softly while at the party, "said Mark McNeely, an electrical engineer at a consulting service and engage in research about the comparison of GSM and CDMA networks. According to the study, the GSM mobile phone radiation 28 times compared to CDMA phones.

But there are exception. If you have a CDMA phone but live in the countryside and the nearest base stations located in remote, then the level of radiation can be similar or even higher than the GSM mobile phone to achieve the same tower. In this case, if there is a GSM tower that is closer, the better you are using a GSM phone.
