11. ADVANTAGE: In typical analog cell phone system, each carrier receives about 800 frequencies to use across a city. With the use of this concept, different cells (non-adjacent) can use the same set of frequencies.
30. 6. COGNITIVE EFFECTS 7. ELECTROMAGNETIC HYPERSENSITIVITY The study confirmed longer (slower) response times to a spatial working memory task when exposed to RFR from a standard GSM cellular phone placed next to the head of male subjects, and showed that longer duration of exposure to RFR may increase the effects on performance. Several unspecific symptoms during and after use; ranging from burning and tingling sensations in the skin of the head and extremities, fatigue , sleep disturbances, dizziness , loss of mental attention , reaction times and memory retentiveness, headaches, malaise, tachycardia ( heart palpitations), to disturbances of the digestive system . Reports have noted that all of these symptoms can also be attributed to stress and that current research cannot separate the symptoms from nocebo effects.
31. 8. GENOTOXIC EFFECT 9. SLEEP AND EEG EFFECTS Sleep, EEG and waking rCBF(regional cerebral blood flow) have been studied in relation to RF exposure for a decade now, and the majority of papers published to date have found some form of effect. Australian research conducted in 2009 by subjecting in vitro samples of human spermatozoa to radio-frequency radiation at 1.8 GHz and specific absorption rates (SAR) of 0.4 to 27.5 W/kg showed a correlation between increasing SAR and decreased motility and vitality in sperm, increased oxidative stress , stimulating DNA base adduct formation and increased DNA fragmentation .
32. 10. DECREASED HIP-BONE DENSITY Men who routinely wear their cell phones clipped to their belts have a reduced bone mineral content (BMC) and bone mineral density (BMD) in the hip, according to a study from National University of Cuyo, Mendoza, Argentina. Electromagnetic radiation is theorized to be the cause of the decrease in bone strength.
44.
