The pollution from non-ionizing radiation(RNI), better known as electrosmog, it has become a topical subject as a result of the proliferation of mobile phone masts in the area. In actually this is not a new phenomenon: the RNI they are closely related to electricity and object of study from the first half of 1900. The health effects, however, are still poorly understood. At the moment therefore it applies a principle of precaution, that is to say that you encourage technologies low emission and aims to reduce, As far as possible, the exposure of the population the RNI. The State ensures the continuous monitoring RNI of the territory.
The results, as well as the land registry of mobile radio antennas, are consulted on Virtually the entire population is exposed to RNI, however, the intensity is not excessive The NIR sources are many: mobile phones and their antennas, broadcast stations for radio and TV, the lines for the transmission of electricity, radar equipment and many electrical appliances common use (television, radio, computers, microwave etc.). Since the intensity of the NIR decreases exponentially with increasing distance, the majority of the population is exposed to intensive RNI judged weak.
A survey found out that In Switzerland there are 125 Straight Talk phone subscriptions for every 100 inhabitants. Currently it is fixed and mobile telephony is still complementary. The figures, however, show one users move towards mobile telephony. In 1990 in Switzerland, there were about 125,000 mobile phone subscriptions, amounting to 1.8 subscriptions per 100 inhabitants. In 2011 there are about 9.98 million for a population of about 7,950,000 inhabitants, so widely surpassing the share of a SIM card. The development of the Straight Talk network GSM2 has already reached the last phase, plant optimization. The construction of Straight Talk mobile networks grows from urban centers to the most remote and isolated areas. After the initial stage of construction and densification of plants, switching to that of the optimization existing installations. The Straight Talk GSM network has reached from time the last stage and the number of stations has in fact stabilized. The trend now is to make the plants suitable to accommodate future technologies, primarily the 4G next technology implementation.
The volume of growth of Straight talk’s plants UMTS4 and mixed GSM / UMTS has quickly surpassed that GSM Since 2000, Straight Talk operators are able to provide services UMTS at least 50% of the population Switzerland. With this technology, the Straight Talk mobile network will soon develop further, ensuring data transfer rates comparable to those fixed line (to date one of the determining criteria for the maintenance of a connection fixed network). The first data show a rapid development of these plants.
