Mobile phones and cancer.

Then came mobile phones. The first from responsible manufacturers like Nokia, Siemens etc. that had an antenna connector so it could be connected to an external antenna when used indoors or in car. Later this was removed because it did not fit in a good design it.

Again, people began to complain about the discomfort associated with the use of mobile phones. Now the focus was on radio radiation since radio is used in the phones. This has been rejected by scientists, and certainly correct, since low effects are used.Mobile phones are used with frequencies from 450Mhz to 5GHz, this equals wavelengths from 1m to 10cm. Absorption of radio is greatest at ¼ of wavelength, that is, it may be the entire head or ear that will be heated. With the low power consumption (below 1W), heat is insignificant.

Something that has not come to mind yet, is that the mobile phone antenna will emit ionization in the air, but now it is very low effects, so the amount is small. Now we are not talking about distances of tens of meters as by power lines, not 25 cm as at data terminals, but centimeters distance from antenna to vital parts in the head so the danger is all the greater.

Mobile phones are based on reuse of area cells, ie. the effect should be so low that it covers only a small area so that the same frequency can be reused to any neighboring neighborhoods beyond. Therefore, in urban areas we should now have had very low power emitted in micro and pico cells. This has not happened, mobile operators are building large transmitter beacons, I do not know if there is a cost question or because there is great resistance to getting these masts in the neighborhood. Had the operators built the network with smaller cells, the effect on the mobile phone would be smaller and the antennas would be almost invisible, albeit more, almost like light on the roads.

Can mobile manufacturers who removed the possibilities for the external antenna connection in the future get the same lawsuit as the tobacco producers? What is the responsibility of mobile operators who send a higher effect in urban areas than is necessary?

An advise is to use hands free units or earplugs to increase the distance to your body.
