Cause of the Hum Different assumptions about the source of the hum (heating of buildings, industrial plants in the neighborhood, individual ear problem, wrong nutrition, military experiments…) have so far not been confirmed.
Latest research in Germany points to mobile communication radio waves (base station antennas) as source of the hum. The hum is not caused by the cell phones themselves but by the emissions of the basis stations (antennas) transported over the air interface. The low frequent pulsing and modulations of the signals lead to acoustic resonance in buildings.   Beyond ear perception, the radiation is also otherwise physically noticed by humans. 
Reasons that speak for mobile communication as source of the hum:
– correlations between peoples´ reports of first hearing the hum and the setup of antennas in their neighborhood, clearly demonstrable in small towns and villages; increase of the phenomenon parallels setup of antennas;
– physical complaints of hum sufferers are the same as the symptoms that are reported for radio wave sickness
– measurements show artificial signals in the ELF-range; qualitative signal analyses show characteristics of portable radio technology (pulsing, modulation)
– effects of radiation by mobile radio waves on human brain waves in the ELF-range have already been medically proven.
ELF frequencies in mobile communication technology as cause of the hum?  Many people are not aware of the fact that – besides RF frequencies – also low frequencies (ELF frequencies) play an important role in mobile communication technology. This is not only the case with regard to the cell phones (as has been focussed in most publications), but also with regard to the so called “base stations”. Low frequencies are used in two techniques: in signal pulsing and in wave modulation.
Signal pulsing Pulsing means that the signal is periodically interrupted. This interruption plays an important role in GSM. GSM works with 8 time slots of 576
μs that are combined to a time frame of 4.615 ms. The time frames are interrupted by short pauses. The result is a pulsed signal of 1736 Hz.
The time slots themselves are combined to a so called “multi frame”. A multi frame comprises of 25 time frames plus a pause (i.e. 26 time frames). The result is a pulsed signal of 8.33 Hz, i.e. with a periodicity of 120 ms.

Multirahmen = multi frame; Zeitrahmen = time frame; gepulstes Signal = pulsed signal
These signals are sent by each basis station 24h a day on the Broadcast Channel (BCCH). The broadcast channel is an organizational channel that indicates the existence of the base station and therefore is always run with full power. Through the broadcast channel,  7 calls can be transmitted at the same time.
When more than 7 callers use the base station, another channel is added. Each call is then transmitted over one of the 8 time slots. One call results in a pulsed signal with a periodicity of 217 Hz (fig.2). According to the number of calls, additional channels add to the emissions of the base station.

mobile2 Unlike the broadcast channel, the other channels adapt their emissions to the actual needs. Each channel is regulated seperately. The result is an irregularly pulsed signal (fig. 3). Overlapping frequencies reinforce each other.

Low frequency modulation In mobile communication technology, low frequencies are also used to optimize signal transmission. Modulation means that the main signal is mixed with another frequency (carrier frequency) that serves as transportation medium.
There are several types of modulation. In mobile communication technology, especially digital modulation is used. The methods comprise simple OOK (onkey-offkey) modulation, audio frequency shift keying (AFSK), phase shift keying (PSK), pulse-amplitude modulation (PAM), pulse frequency modulation, pulse code modulation and many others. According to the coding options they offer, several subtypes are distinguished (e.g. 4PSK, 8PSK etc.).
A modulation type which is very often used in mobile communication technology is the so called TDMA modulation (time division multiple access) which uses a frequency of about 50 Hz.
Low frequency modulation in the range of 5 to 20 Hz is also used for power regulation with regard to moving cellular phones.
Warning by the European Parliament Already in 2001, the European Parliament warned against the use of ELF frequencies present not only in the so called handset but also in the emissions of the antenna.of mobile base stations.
 „Of particular importance is the emphasis given to
(i)                   the fact that electromagnetic fields are not alien to living organisms, but play a crucial role in controlling and maintaining their orderly functions – i.e. that a living organism is an electromagnetic instrument of great and exquisite sensitivity.
(ii)                 The subjectiveness of human vulnerability, which necessarily follows from the inherently non-linear nature of the problem, which is here recognised ab initio, and
(iii)                The presence of ELF features both in the microwave pulses emitted by the antenna of a mobile phone and in the (much more penetrating) magnetic field associated with the surges of Electric current from the battery of the handset, which are necessary for the generation of the microwave pulses.

Sedona Vs Smart Meters

Published on Feb 25, 2014

On February 20th 2014 many residents of Sedona Arizona turned out to attend a meeting at City Hall to discuss the installation of “the Smart Meter.” We have many statements and opinions from our residents on this video why they are not happy with the smart meters in our community. Sedona is a wondrous place for it’s residents and the domestic and international visitors which number in the millions, who visit us annually. We all wish to preserve the integrity of this sacred and magical place.
