Yes, I am feeling worse since 4G came to Seattle.  More skin burning.

Maybe someone knowlegable in Telecommunications can help me here.  This is as far as I got tonight in trying to break down the basics of 4G:

4 G refers to 4th Generation.

When going from one generation to another, there is an up grade of technology.

1G or 1st Generation refers to the analog signal used by cellular towers in the 1980s.

2G or 2nd Generation technology was in the 1990s and upgraded the analog signal to digital and let people send text messages across the network

3G  or 3rd Generation technology, in the early 2000s, made use of electromagnetic wavelengths to broadcast a wireless broadband signal, which let users access the Internet and download applications using handheld mobile devices

4G or 4th Generation technology further upgrades previous wireless networks with FASTER INFORMATON TRANSFER TIMES, heightened security, and greater information exchange abilities. 4G services have become necessary to satisfy the high demand by customers to USE THEIR PHONES  to download HIGH LEVELS OF DATA, for example, by watching videos or accessing emails. Mobile data has increased 250 per cent over the past two years. 

The International Telecommunications Union has decreed that the 4G label should only be used for services which can offer speeds of 1 GIGABIT PER SECOND.   By comparison, 3G or third-generation networks offer data transmission speeds averaging around 200 kilobits per second (kbps), which is significantly slower than 4G technology. 

How much faster is data transmission with 4G than 3G?

4G = 1 Gigabit (or 1024 Megabits) per second = 1,048,576 kilobits per second divided by 3G (200 kilobits per second) = 5,242.88

So 4G data transmission is about 5,000 times faster than 3G!!

To compare this to computer language, Your Hard drive stores Gigabytes of information, whereas, Computer Processor Speed is measured in GHz and Mhz.

But data transmission SPEED is one thing and Microwave intensity is another, so we move from Gigabits to Gigahertz. because there is no direct conversion between frequency and bit rate. 

Microwaves are a subset of Radio Waves.  With regards to wavelengths, the higher the Frequency, the shorter the wavelength.  Frequency is how many vibrations or cycles per second.

Microwaves  range from 300 MHz to 300 GHz and hence their wavelength ranges from 1 millimeter to 1 meter.

WAVELENGTHS:

Average AM Radio Wavelength = 300 meters (or about 1,000 feet in length).
Average television and FM radio wavelength = about 3 meters (or about 10 feet in length).
Average Microwave Wavelength = less than 30 cm. which is considerably shorter than radio waves.

Microwaves travel in straight lines, much like light waves do. Dish antennas are often used to collect and focus microwave signals.

The 2G wavelength has a frequency of 800 - 1900 Mhz or 1.9 Gigahertz

The 3G wavelength has a frequency of 2100 Mhz  (or 2100 cycles per second) or 2.1 Gigahertz. 

The 4G wavelength has a frequency of 2300 Mhz  or 2.3 Gigahertz.

If you know the Frequency of a wave, which we do above, the industry accepted formulas is

Wavelength = 300 / Frequency in Mhz. with the result given in meters.

3G wavelenth = 2100 Mhz / 300 = 0.14285714285714285 meters or 5.6 inches.

So when you make a call on your cell phone using 3G technology, the microwaves penetrating your skin have a wavelenth of 5.6  inches, and are coming at you 2100 times a second. The frequency of 2100 times a second wrecks havoc on your cells.  You are 90% water and these frequencies penetrate your skin where they vibrate and heat your cells, just like a microwave oven does.  That is what causes the burning, prickling feelings on your skin.

The 4G wavelength is 2300 Megahertz. That translates to 0.13043478260869565 meters long or 5.1  inches long. 

WITH 4G we have a slightly shorter 5.1 inch long wave, cycling with a frequency of 2300 times a second.  In 3G the wave is 5.6 inches long cycling at 2100 times a second.  So the 4G wavlength cycles 200 times MORE per second than 3G.   A wave of radiationn penetrating your skin with more cycles per second spells increased  heating of cells, but you  may not notice the SLIGHT increase from 3G to 4G in that regard.  What you may notice is the extremely amped up ACTIVITY of the microwave highway, which metaphorically has been expanded from one lane to 6 lanes. 

This greatly amped up activity of the system referred to as "higher network capacity" with "More simultaneous users per cell", INCREASED DATA SPEEDS  of 100 mbps between  two points, global roaming across multiple networks, means EXTREMELY HIGH amounts of data will be coming though widely expanded frequency channels. 

Well, all of this spells increased amounts of databits flying back and forth through our air space, 5,000 times faster than before, between cell phone and tower, which means more Microwave Activity consisting of microwaves with a slightly stronger intensity than 3G. 

This is as far as I got.  Can someone give an idea of how much more Microwave Activity we will be getting with 4G due to the increased speed and throughput of informaton?  Thanks.

I never noticed any difference from 4G either, but some people here

really did notice the difference.
